Intelligent Voice Activated Drone(s) for in-Vehicle Services and Real-Time Predictions2021-01-00634/6/2021
Today, commercially available drones have limited use-cases in the rapidly evolving community. However, with advances in drone and software technology, it is possible to utilize these aerial machines to solve problems in a variety of industries such as mining, medical, construction, and law enforcement. For example, in order to reduce time of investigation, Indiana State Police are currently utilizing ad-hoc commercial drones to reconstruct crash scenes for insurance and legal purposes. In this paper, we illustrate how to effectively integrate drones for in-vehicle services and real-time prediction for automotive applications. In order to accomplish this, we first integrate simpler controls such as voice-commands to control the drone from the vehicle. Next, we build smart prediction software that monitors vehicle behavior and reacts in real-time to collisions. Furthermore, we employ object recognition techniques through In-Vehicle Infotainment (IVI) systems to identify the surroundings based on inputs from drone-mounted camera sensors. Consequently, we implement object identification and smart maneuver of the drone in relation to the vehicle; as well, employ timely deployment of the drone prior to collision for emergency assistance and crash reconstruction purposes. The goal is to optimize performance and amplify safety and security of the vehicle. The prototype detailed in this paper was tested on a vehicle moving at a speed of 45 mph. The driver of the vehicle can deploy and control the drone using voice commands. The drone follows the vehicle and is in-sync with the vehicle and performs tasks to aid in post-collision assistance and crash reconstruction.

The next generation of hearing aids might match a listener's brainwaves with the “soundprint” of a speaker's voice, using that information to automatically turn up the volume on that speaker, according to a new study in a recent issue of Science Advances.
Streamlined HMIs do more with less19TOFHP04_084/1/2019
The phrase “less is more” has been a major part of human-machine interface (HMI) designs for several years as developers traded multiple knobs and buttons for cleaner input techniques. However, the push to simplify the control's look and feel is offset by the need to let drivers and operators manage more things, often with redundant input techniques. The growing number of electronic features and functions comes as vehicle buyers demand controls that can be learned quickly. This need to manage more complex tasks without much training marks a major change from the era when operators slowly learned how to maneuver mechanical controls. New designs will need to further simplify the vehicle environments designed to provide more digital functionality.

WHAT WE'RE DRIVING18AUTP10_0510/1/2018
Mercedes-Benz is fond of saying it cascades at least some of the S-Class' posh luxury and technology throughout its range. That's just what it has done for the fourth-generation A-Class, the nameplate that sits at the bottom of the brand's lineup. The new A-Class is heaped with cabin tech, in particular. Built on Mercedes' MFA2 front-wheel-drive platform, the A200 AMG Line version driven is well-connected, having the MBUX (Mercedes-Benz User Experience) touchscreen interface (and a touchpad), plus “Hey Mercedes” voice recognition.
Switching to comfort mode18TOFHP08_088/1/2018
Switches, knobs and touch panels evolve to reduce operator fatigue. Programmability has become a central design element for engineers tasked with making work environments more comfortable for commercial-vehicle operators. Touchscreens continue to handle more functions, while switches, knobs and joysticks are all becoming more versatile as embedded electronics turn them into multi-function controls. There's a shortage of drivers in trucking and operators in off-highway, prompting a major focus on making sure that workers in both fields stay on the job. A range of control technologies play a major role in the effort to improve comfort for those who spend long hours working in cabs.

Classification of Time Series Measurement Data for Lock-Up Clutch of Automatic Transmission of Vehicles Using Deep Convolutional Neural Networks2018-01-03994/3/2018
A newly developed classifying method for time series measurement data of automatic transmission of vehicles is presented. The proposed method uses deep convolutional neural networks to learn what is comfortable acceleration. In addition, our proposal method employs supervised learning based on experienced engineer’s criterion. As a demonstrative problem, we consider the classification of time series measurement data for lock-up clutch control of an 8 speed automatic transmission.

Memristors Enable Quick-Learning Neural NetworkTBMG-285603/1/2018
Inspired by brains, neural networks are composed of neurons (or nodes) and synapses, which are the connections between nodes. To train a neural network for a task, a neural network takes in a large set of questions and the answers to those questions. In this process of what’s called supervised learning, the connections between nodes are weighted more heavily or lightly to minimize the amount of error in achieving the correct answer.
Analysis of Vehicle Voice Recognition Performance in Response to Background Noise and Gender Based Frequency2017-01-18886/5/2017
Voice Recognition (VR) systems have become an integral part of the infotainment systems in the current automotive industry. However, its recognition rate is impacted by external factors such as vehicle cabin noise, road noise, and internal factors which are a function of the voice engine in the system itself. This paper analyzes the VR performance under the effect of two external factors, vehicle cabin noise and the speakers’ speech patterns based on gender. It also compares performance of mid-level sedans from different manufacturers.

The Effect of Vehicle Noise on Automatic Speech Recognition Systems2017-01-18646/5/2017
The performance of a vehicle’s Automatic Speech Recognition (ASR) system is dependent on the signal to noise ratio (SNR) in the cabin at the time a user voices their command. HVAC noise and environmental noise in particular (like road and wind noise), provide high amplitudes of broadband frequency content that lower the SNR within the vehicle cabin, and work to mask the user’s speech. Managing this noise is a vital key to building a vehicle that meets the customer’s expectations for ASR performance. However, a speech recognition engineer is not likely to be the same person responsible for designing the tires, suspension, air ducts and vents, sound package and exterior body shape that define the amount of noise present in the cabin. If objective relationships are drawn between the vehicle level performance of the ASR system, and the vehicle or system level performance of the individual noise, vibration and harshness (NVH) attributes, a partnership between the groups is brokered. Compatible targets are set and hardware selected that works to meet both groups’ goals. This paper examines the NVH attributes and performance metrics that relate to vehicle level ASR performance, and finds that strong relationships and statistical trends can be drawn between the Sentence Error Rate (SER%) and standard NVH metrics for that road surface or HVAC configuration. The paper also establishes that AI% should be the preferred metric to relate cabin noise to ASR performance in the presence of any other kind of steady state noise.

Low-Power, Special-Purpose Chip for Speech Recognition in ElectronicsTBMG-268635/1/2017
Automatic speech recognition is on the verge of becoming the chief means of interacting with computing devices. To address this, MIT researchers have built a low-power chip specialized for automatic speech recognition. Whereas a cellphone running speech recognition software might require about 1 Watt of power, the new chip requires between 0.2 and 10 milliwatts, depending on the number of words it has to recognize. That probably translates to a power savings of 90 to 99 percent, which could make voice control practical for relatively simple electronic devices, including power-constrained devices that harvest energy from their environments, or go months between battery charges.
Computer Chips Calculate and Store in an Integrated UnitTBMG-265183/1/2017
Researchers at the University of Wisconsin-Madison created computer chips that can be configured to perform complex calculations and store massive amounts of information within the same integrated unit, and communicate efficiently with other chips. Called “liquid silicon” — liquid for software and silicon for hardware — the technology has uses in data-intensive applications such as facial or voice recognition, natural language processing, and graph analytics.

The stretchable device captures physiological sound signals from the body, has physical properties matched with human skin, and can be mounted on nearly any surface of the body. The sensor resembles a small Band-Aid®, weighs less than one-hundredth of an ounce, and can gather continuous physiological data.
SAE Convergence 201616AUTP11_0111/1/2016
Talk of the healthy aspects of disruption mingles with SAE's renowned technical emphasis to foster the auto industry's continuing evolution toward electrification and autonomy. The auto industry is at the moment ravenous for discussion and guidance regarding the ongoing integration of electronics into vehicle development-but particularly regarding the almost daily deluge of news and speculation about vehicle automation. SAE's 2016 Convergence conference supplied a diverse forum for those conversations while providing a new format that grouped each of the conference's three days into a distinct subject-matter theme. From an insightful, consumer-focus keynote address from Ford's Raj Nair, Executive Vice President, Product Development and Chief Technical Officer, to technical sessions that explored everything from trends in human-machine interface to supply-chain transformation, Convergence once again was the rallying point for technical and strategic discussion at a high level.

Reducing Sensor and Readout Circuitry Noise in Digital Domain Using Reference PixelsTBMG-2552210/1/2016
One of the main heritage tools used in scientific and engineering data spectrum analysis is the Fourier Integral Transform and its high-performance digital equivalent — the Fast Fourier Transform (FFT). The Fourier view of nonlinear mechanics that has existed for a long time and the associated FFT carry strong a-priori assumptions about the source data, such as linearity and being stationary. Natural phenomena measurements are essentially nonlinear and nonstationary.
Sub-Audible Speech Recognition Based on Electromyographic (EMG) SignalsTBMG-239082/1/2016
Sub-audible speech is a new form of human communication that uses tiny neural impulses (EMG signals) in the human vocal tract instead of audible sounds. These EMG signals arise from commands sent by the brain’s speech center to tongue and larynx muscles that enable production of audible sounds. Sub-audible speech arises from EMG signals intercepted before an audible sound is produced and, in many instances, allows inference of the corresponding word or sound. Where sub-audible speech is received and appropriately processed, production of recognizable sounds is no longer important. Further, the presence of noise and of intelligibility barriers, such as accents associated with the audible speech, no longer hinder communication.

Hard to answer15AUTD01_011/1/2015
Technical and personal issues make it challenging to link smartphones to vehicles. Human-machine interfaces (HMIs) are quickly evolving as smartphones and apps enter vehicles. Developers are allowing multiple ways for drivers to interact with apps and phones, knowing that a well-designed HMI can be a significant differentiator while a problematic HMI can become fodder for highly-publicized criticism. The tightening link between cars and consumer devices is challenging vehicle designers who must adopt consumer technologies for control. Most executives agree that a range of control and display technologies will be needed to manage apps and phones.

Integrated Technologies Take Medical Device Development to the Next LevelTBMG-200767/1/2014
According to the Journal of Patient Safety, a whopping 210,000 to 440,000 deaths attributable to medical errors occur in hospitals every year. Clearly, there is a desperate need for technology to take a leading role in medical device development in order to improve patient outcomes and save money. The two emerging technologies in the medical space are context-aware technology and multi-input technology.
Speech Acquisition and Automatic Speech Recognition for Integrated Spacesuit Audio Systems, Version IITBMG-199196/1/2014
Astronauts suffer from poor dexterity of their hands due to the clumsy spacesuit gloves during Extravehicular Activity (EVA) operations, and NASA has had a widely recognized but unmet need for novel human-machine interface technologies to facilitate data entry, communications, and robots or intelligent systems control. A speech interface driven by an astronaut’s own voice is ideal for EVA operations, since speech is the most natural, flexible, efficient, and economical form of human communication and information exchange.
State of the Art Technologies in Automotive HMI2014-01-02584/1/2014
Human Machine Interface technologies in automotive systems are taking a giant leap forward with integrated multi-modal, multi-touch and multi-zone systems. This evolution enables the HMI system to provide state-of-the-art graphics effects, speech assistance, touch and gesture enabled interfaces, augmented reality, web and mobile integration alongside other advanced concepts, providing excellent user experience, least driver distraction and ease of use. Modern premium car manufacturers are introducing such user experience in their in-vehicle infotainment (IVI) systems to make their IVI on par with the trend setting mobile smart phone user experience. Apart from the technologies involved in multimodal behaviour, the HMI system includes frameworks, standards and sub systems that enable appreciable amount of autonomy while interfacing with the underlying IVI sub system layers. This paper discusses the technologies, practices and implementations in the current and upcoming industry trends. We present some of our own work on HMI architecture and customizable HMI Design Tool Framework. We hope this would help the IVI community, especially in Tier 1 and Tier 2, to identify technologies where they may focus and position in the infotainment HMI technology arena.

Bright outlook for glass cockpits12AERD0215_012/15/2012
Cockpits are adopting larger screens and touch input, using modularity to ease upgrades. Growth in the number of planes flying globally, combined with a declining number of skilled pilots, is prompting a change in cockpits designed to make flying simpler. Larger displays make it possible to show data that is relevant, while touch control is being used to reduce clutter by eliminating buttons. Before these techniques are employed to reduce the cognitive workload, they're heavily vetted. As engineers devise techniques that guide pilots to the right actions and migrate to more intuitive controls, many are delaying the adoption of voice controls. Things are also changing behind the display panels as more modular systems are used so it's easier to update systems as new features and functions become available.

On driver distraction, the ‘eyes’ have it11AEID0621_016/21/2011
There is disagreement among researchers about how significant a problem mind-off-the-road is, but everyone agrees it's a good idea to look where you're going. Keeping one's attention trained entirely on operating the vehicle is asking too much of the average person, research suggests. Racecar drivers can stay focused, but the rest of us generally have something else on our minds while we're tooling down the highway. That particular state of affairs on our roadways, and in our minds, causes less worry for Ford driver distraction expert Louis Tijerina than it might for the average person. Were it not for hard data supporting his attitude, he might not have arrived at this seemingly counterintuitive view of the matter.

Speech Acquisition and Automatic Speech Recognition for Integrated Spacesuit Audio SystemsTBMG-870011/1/2010
A voice-command human-machine interface system has been developed for spacesuit extravehicular activity (EVA) missions. A multichannel acoustic signal processing method has been created for distant speech acquisition in noisy and reverberant environments. This technology reduces noise by exploiting differences in the statistical nature of signal (i.e., speech) and noise that exists in the spatial and temporal domains. As a result, the automatic speech recognition (ASR) accuracy can be improved to the level at which crewmembers would find the speech interface useful. The developed speech human/machine interface will enable both crewmember usability and operational efficiency. It can enjoy a fast rate of data/text entry, small overall size, and can be lightweight. In addition, this design will free the hands and eyes of a suited crewmember.
Integrated Spacesuit Audio System Enhances Speech Quality and Reduces NoiseTBMG-586711/1/2009
A new approach has been proposed for increasing astronaut comfort and speech capture. Currently, the special design of a spacesuit forms an extreme acoustic environment making it difficult to capture clear speech without compromising comfort. The current system, called Communication-Cap-based Audio (CCA), relies on a single microphone placed close to the subject’s mouth. While this results in clear audio, it also has problems: wire fatigue, blind mating, interference with food/drink, need for custom communication caps, and not being able to adjust the microphone during extravehicular activities.
Processing Electromyographic Signals To Recognize WordsTBMG-51955/1/2009
A recently invented speech-recognition method applies to words that are articulated by means of the tongue and throat muscles but are otherwise not voiced or, at most, are spoken sotto voce. This method could satisfy a need for speech recognition under circumstances in which normal audible speech is difficult, poses a hazard, is disturbing to listeners, or compromises privacy. The method could also be used to augment traditional speech recognition by providing an additional source of information about articulator activity. The method can be characterized as intermediate between (1) conventional speech recognition through processing of voice sounds and (2) a method, not yet developed, of processing electroencephalographic signals to extract unspoken words directly from thoughts.
Honda Next Generation Speech User Interface2009-01-05184/20/2009
Honda, working closely with IBM for their model year 2009 introduction, will be releasing the next step in the evolution of speech user interfaces in vehicles. The new Honda vehicles will include the leading edge Free Form Command (FFC) technology developed by IBM as part of its IBM Embedded ViaVoice (EVV) product line. At its core, Free Form Commands improve the overall end-user experience by creating a system that is easier to use out of the box by increasing the overall usability of the system. Free Form Commands employ an innovative approach which allows Statistical Language Model technology to be deployed within the constraints of an embedded computing environment. This technology allows users to speak commands that are not part of a predefined fixed set of phrases, as is required in today’s vehicles, but instead speak command phrases that match the application functional area they are targeting. The FFC technology goes beyond just recognizing what phrase is spoken, in that the system also uses statistical models to determine the meaning of the phrase via semantic interpretation. For example, in today’s systems, the system designer chooses what commands can be spoken to change the radio station, such as “radio tune 97.9”. When a system is designed using Free Form Commands, the system designer specifies that the user should be able to change the radio station, then using statistical modeling techniques, models are developed that enable this task. As a result, the end-user can now speak a variety of natural phrases to complete that task, such as “tune the radio to 97.9”, “I want to listen to 97.9”, “switch to 97.9”, “change to 97.9”, etc…. This leads to an easier to use system providing greater end-user satisfaction. The improvement in usability is a direct result of reducing the amount of information the user has to memorize. With the previous releases of the system, the user had to remember specific format and phrases of the commands, but with FFC technology, the user only needs to know the type of commands that the system will understand and speak a phrase that is natural to them in that context. In this paper, we will discuss how Honda engaged IBM at the early stages to produce research level prototypes to set the direction for the technology, We will then describe Honda’s and IBM’s refinement of the technology to target a system that would be deployable in a vehicle, the testing and methodology used to validate the solution was valuable to the end-user, and an overview of the Free Form Command technology.

Automated Functional and Robustness Testing of Vehicle Infotainment System2009-01-13664/20/2009
In a current premium vehicle the infotainment system is typically implemented as a distributed system consisting of a number of modules communicating via a Media Oriented Systems Transport (MOST) network. Typical issues with such systems of systems (SoS) are emergent behaviour as systems interact in an unanticipated manner particularly during some initialisation conditions where it may be possible to get delays and failures in individual systems. Testing of infotainment systems at an overall level is conventionally carried out manually by an expert who can observe at a customer level but this has limitations affecting test coverage and effectiveness. Hence there is a requirement for an automated infotainment testing system which replicates a human expert encompassing relevant sensory modalities relating to control (i.e. touch) and observation (i.e. sight and sound) of the system under test. This paper describes the design and development of such a system that consists of simulation of vehicle CAN, vision-based inspection, navigation of features, random cranking waveform generation, sound detection and test automation. The system developed is able to; stimulate the system across a wide variety of initialisation conditions, exercise each function, check for correct operation and record failure situations for post-testing analysis.

User-centered Human-Machine-Interaction (HMI) Design for Automotive Systems2008-21-000410/20/2008
Multimedia systems, GPS navigation, entertainment, and communication (infotainment) have become increasingly popular in today's cars. On one hand, these systems offer a desirable amount of comfort and convenience. On the other, the representation of information on displays and navigation through these virtual worlds leads to increased driver distraction within a constantly changing environment that could be dangerous to road safety. For this reason, Human-Machine-Interaction (HMI) Design needs to be addressed. This paper will present a problem-driven, user-centered cognitive approach. It also shows how HMI Design transfers research findings into efficient product development. There is a very complex relationship between the user, the interface and the traffic environment. Psychological factors, the driving situation, and interface properties affect drivers' behavior. Design parameters for interaction concepts will be shown. As interaction design concepts represent designers' hypotheses, it will also be shown how these HMI concepts are tested. Within this phase users add their perspective to measure subjective and objective interaction efficiency. The reader will experience a combination of primary research, secondary research, and product examples that render a holistic HMI development process between analysis and synthesis with a shared goal; encouraging driver support, reducing distraction, and making driving more enjoyable.

Designed Interface for Users of Powered Wheelchair with Arms or Hands Deficiency2007-01-286711/28/2007
Actually, wheelchair users with impairment or total lost of movements in arms or hands have many difficult to operate conventional motorized wheelchair. This project develop and integrate support systems having focus in a friendly user interface, like voice recognition, filters in joysticks, sonar for collision avoidance and motor drivers, all integrated by a hierarchic control architecture. Voice recognition was developed in two different architectures and implementations methods: the first by using commercial voice recognition software and the second by a microcontroller firmware, allowing a significant cost and weight reduction. For wheelchair user with hands or arms impairment like repetitive strain injuries or muscular dystrophy a joystick filter must to be used to interpret the movements where oscillate around a desired position. Since different kinds of interfaces and inputs are used, a consistent integration is necessary between them. The integration system uses a hierarchical logic, meaning that are some inputs are predominant than others when used, and stays in an idle condition until an event occurs. Hierarchical logic can be used for input management or obstacle avoidance, when an unsafe command is performed, like to drive to close of a wall, when the navigation system will disable some movement's directions. To evaluate this project, a prototype was built in reduced scale, but conserving all sensors and navigation architecture characteristics.

Heads Up Display2007-01-35218/5/2007
This paper presents a novel design approach for an automotive full-windshield Head-Up Display (HUD) interface which aims to improve the driver's spatial awareness and response times under low visibility and/or time critical conditions. Heads-up display is an electronically generated display that is superimposed upon a driver's forward field of view. The display element is largely transparent, meaning the information is displayed in contrasting superposition over the user's normal environment. HUD comes very handy for whom changing their view to look at the instrument cluster could prove to be a fatal distraction. The information is projected with its focus at infinity. Doing this means that a user does not need to refocus his eyes (which takes several tenths of a second) when changing his attention between the instrument and the outside world. The HUD communicates configurable information, such as navigation, performance features as well as vehicle speed to the driver. As we were adding great new features, such as a wide array of user-selectable displays, it was important that the image be as crisp and clear as possible. This paper also touches the challenges involved in the HUD design and introduces the visual components of the interface

A Reference Architecture for Infotainment Systems2006-21-001310/16/2006
Volvo Car Corporation has developed a Reference Architecture for PAG1 Infotainment Systems. A Reference Architecture is an architecture scoping over more than a single system, i.e. an architecture aimed for a family of systems. The Infotainment Reference Architecture has since 2001 been successfully applied for the PAG family which so far covers the infotainment systems of Volvo XC90, Volvo S40/V50, Jaguar XK, Aston Martin DB9 and the brand new Volvo S80. In 1999, the system design departments started up with the clear objective to develop a system solution aiming for the PAG infotainment system family. The work was carried out according to the established development process at Volvo Cars. A year later a discouraging design review was performed. The number of involved functions, the level of function interaction and the distribution of functionalities between ECUs resulted in a non-manageable system solution. These findings implied that large efforts late in integration phases would be needed and the problem was decided to be tackled upfront. A small architecture team was formed, which after two months rolled-out the “Reference Architecture for PAG Infotainment Systems”, defining the strategies and structures addressing the identified problems. This paper gives a detailed description of the technical implementation, usage, evolution and maintenance of the PAG Infotainment Reference Architecture. This paper will also present experiences and lessons learned when working architecture-centric in automotive system development.

Intelligent Navigation for Music and Media from Multiple Sources2006-21-005210/16/2006
The adoption of digital media in the car is rapidly growing; with that are an increasing number of disparate media sources such as portable media players, satellite radio, and HD radio. Media sources utilize various user access models creating a critical standardization problem in the entertainment sub-system design making navigating media in the car not only difficult but a dangerous driver distraction. Each media source creates different metadata and uses slightly different user models contributing to the overall lack of metadata standardization and can result in inaccurate or missing tag information, and multiple categories for the same piece of media. A band like “The Rolling Stones” may be categorized as “Classic Rock” on a satellite system but as “Rock” on a portable MP3 player plugged into the entertainment subsystem. In the car, lack of standardized metadata creates a dangerous environment as the consumer is forced to manually navigate through media; a serious driver distraction. Solutions addressing these issues use technology to unify the metadata from virtually any media source and offer advanced ways to simplify media and music navigation such as; personalized playlisting technology-allowing rapid access to the appropriate content; extended metadata, for DVDs for example, allowing access to program content from the rear seat as well as providing filtering options for the parents; and voice control capabilities allowing drivers to keep their eyes on the road and their hands on the wheel while navigating their media collection through intuitive voice commands. Intelligent navigation in the car is the must have technology that allows consumers to better manage, enjoy and discover digital media.

Shaping the Future of the Automotive User Experience: Design-for-Experience & the Last-Inch Problem2006-21-005010/16/2006
The communications and computing technologies underlying the future automotive user-experience are described in terms of what a typical consumer might see: built-in, beamed-in and brought-in services. A design-for-experience framework is proposed to translate desired experiences into underlying web-enabled services. To realize web-enabled services, the automobile needs to be defined as an information services platform, delivering communications and computing as services. Termed the last inch problem, the challenges associated with delivering this platform are outlined in the paper. Results from the development of engineering concepts and their application to demonstration vehicles are presented.

Using Neural Networks to Identify Squeaks and Rattles in Vehicles2006-01-00994/3/2006
Previous works have developed a methodology to characterize in a unique form annoying noises (squeaks and rattles) that appear inside of automotive vehicles. Thus, for each characterized noise, its origin and alternatives of eliminating it, or to make it more tolerable, are known. Using this methodology, data bases with the squeaks and rattles that typically appear in vehicles have been created. This paper describes the work done towards the development of a tool, based on neural networks, that determines if an squeak or rattle present in a vehicle corresponds to any of the noises already characterized and stored in the database. Using Matlab and experimental results, different types and structures of neural networks have been evaluated in a systematic form. Preliminarily, it was found that for this specific application the best topology is a net with 100 inputs, one hidden layer of 50 neurons with sigmoid active functions and four outputs neurons with linear active functions. Additionally, it was found that the best training method is the gradient descent back-propagation method with a learning rate of 0.05.

Strategy and Challenges for an Integrated HMI2004-21-009110/18/2004
Vehicle interiors are pushing the envelope of style and spaciousness to meet customer expectations. Form follows function of the instrument panel Human-Machine Interface layout is constantly challenged and compromises often must be made to support cabin comfort and design attributes. Usability and driver workload must also be considered at the early design stages of vehicle development, as well as at the HMI component level. This paper discusses the technical issues and possible solutions to support both cabin spaciousness and visibility needs, and optimal viewing and control of in-vehicle electronics. The challenges imposed on the user interfaces of such systems as audio, climate control and navigation are discussed and a practical solution is presented. Highlights of related customer needs and field evaluations are also discussed as they have influenced the strategy.

AMI-C Content-Based Human Machine Interface (HMI)2004-01-02723/8/2004
AMI-C (Automotive Multimedia Interface Collaboration) contains an HMI specification to make it easier for multimedia devices to work in different vehicle brands, makes and models, in harmony with each vehicle's HMI. A key concept of the specification that enables this capability is a “content-based” approach to HMI. In this approach, the multi-media device sends its content (pages) to be presented to an OEM-specified “HMI Manager.” The HMI Manager, in turn, formats the content into the form appropriate for a given vehicle model's displays and User Interface Markup Languagei) that is used to communicate between the HMI Manager and the AMI-C compliant device.

The Application of Different NDT Processes for Automotive PM Components2004-01-04923/8/2004
PM parts, similar to those made by other metalworking processes, are not always defect free. Typical defects like cracks or larger pores are usually checked by cumbersome, visual methods with limited effectiveness. Conversely, physical effects can also be used to detect defects through the application of eddy currents, x-ray, optical methods or the measurement of resonance modes. These methods are gaining a wide field of applications in PM today. Some methods investigate the components locally for pre-defined defects, e.g., optical, ultra-sonic or some commonly used sonic inspection systems. Other localizing methods investigate whole components, detecting locations of defects. Sophisticated integral methods allow for the inspection of the whole component. The key point is the signal evaluation. Simple analysis only allows the determination of local defects, i.e., known defects. Sophisticated methods, combined with the right physical analysis, inspect the whole component, so that unknown defects can also be found. For a cost effective selection of defect sorting, the sensing and evaluation methods need to be fast and applicable in automated rigs. Different physical methods and evaluation tactics are presented along with their advantages and limitations for selected PM engine, transmission and seat components.

Visual User Interfaces for Telematics2004-01-02823/8/2004
The term “telematics” is now used to cover a large spectrum of in-vehicle functionality. This functionality has a correspondingly large spectrum of human-machine interface (HMI) needs. These HMI needs range from “headless” functions that require no user interaction at all, to complex functions with rich graphical or voice recognition interfaces. This paper describes the visual elements of a modern telematics system and design problems and the trade-offs that must be made in an automotive environment.
