A method of selectively elevating a Seamless Switch Integrated in Fabric2026-26-0596To be published on 01/16/2026
This research presents the construction and working principle of Selectively Elevated Seamless Fabric Switch technology aimed at advancing automotive interior design through enhanced aesthetics, functionality, and user experience by providing a tactile surface that is available for operation only during the activated, elevated state. Traditional mechanical switches often suffer from issues such as dust and water ingress, accidental activation, and a fragmented visual profile. The proposed system integrates concealed controls sandwiched with a fabric surface, with switches selectively elevated only upon user interaction. The design incorporates conductive fabric layers and electromagnetic actuation to achieve seamless integration with vehicle interiors while maintaining responsive tactile feedback. The input provided for activating the switch can be a signal such as gesture or proximity of the user’s finger. Upon activation the switch is selectively elevated and ready for operation due

Evaluation of Vibration Reduction Techniques in Agricultural Tractors: A Design of Experiments Approach2026-26-0344To be published on 01/16/2026
Operator comfort is among the most crucial features of agricultural tractors. Tractor operators work long hours and are subjected to vibrations and mechanical shocks, which are potentially harmful to their health. When selecting a tractor for agricultural use, one of the main factors to consider is tactile vibrations. The mandate for this project includes an investigation of tractor vibration control issues. For identifying the source of the issue, study of the controlling system is crucial. The objective of the study was to evaluate the vibrations transmitted through the tractor and to reduce vibrations on specific tactile locations through the design of experiments (DOE) method. In this paper, testing is performed on the specified tactile locations; to reduce resonance-induced vibrations, a range of approaches are being explored, including lowering the natural frequency away from the second-order engine frequency and improving the damping coefficient to lower the vibration amplitude

Global Vehicle Vibration Enhancement Using Circular Force Technology2025-01-001505/05/2023
In addition to safety advantages, sound and vibration are being utilized to enhance the driver experience in Electric Vehicles (EVs). Significant interest and investment continue to grow in utilizing interior and exterior sound for pedestrian safety and driver awareness of vehicle state, as well as enabling a unique personal EV audio experience for brand recognition both inside and external to the vehicle. Several automakers are also using audio to simulate virtual gear shifting and as well as manual transmissions in EVs. According to several automotive industry articles and market research, the audio enhancements alone, without the vibration that drivers are accustomed to in combustion engine vehicles, are not sufficient to meet the engagement, excitement, and emotion that driving enthusiasts expect. In this paper, we introduce the use of new automotive high-force compact light-weight circular force generators for globally shaking vehicles. The technology was developed originally for

Low Frequency Modal Management of a Tata Premium Hatchback Car2022-01-036203/29/2022
Tactile feel of vehicle touch points is one of the important criteria of the customer choice while making the buying decisions in the dealership or on a test drive. This tactile feel of a vehicle is majorly governed by the low frequency mode management achieved while designing the vehicle. Different parameters like inclusion of multiple powertrains on a vehicle program, choice of multiple way seating different at driver’s, front passenger’s and rear passengers’ seating positions, instrument panel and steering system designs having higher torque delivery, suspension modes of the front and rear axles based on their articulation and degree of independency, global modes of the vehicle body, the cabin air cavity configuration and volume, etc. play a significant role in deciding this tactile feel of the vehicle being designed. How these parameters were tuned and designed while developing a Tata premium hatchback car has been elucidated with different subsystem development examples. The

Psychosensory Electronic Skin Technology for AI and Humanoid DevelopmentTBMG-3798611/01/2020
In trying to mimic a human being’s five senses, electronic devices such as the camera and TV were developed. As a result, scientists are continuously attempting to imitate tactile, olfactory, and palate senses. Currently, researchers in tactile sensing are focusing on physical mimetic technologies that measure the pressure used for a robot to grab an object but psychosensory tactile research on how to mimic human tactile feelings such as soft, smooth, or rough has a long way to go.
Electronic “Skin” Brings Sense of Touch and Pain to Prosthetic HandsTBMG-3762409/01/2020
Amputees often experience the sensation of a “phantom limb” — a feeling that a missing body part is still there. Pain, while unpleasant, is an essential, protective sense of touch that is lacking in the prostheses that are currently available to amputees. Advances in prosthesis designs and control mechanisms can aid an amputee’s ability to regain lost function, but they often lack meaningful, tactile feedback or perception.
Process Creates Soft Actuated Objects Using Commercial Knitting MachinesTBMG-3738408/01/2020
Computationally controlled commercial knitting machines were used to create knitted objects that are actuated by tendons. New software makes it possible for the objects to emerge from the knitting machines in their desired shapes and with tendons already embedded. They can then be stuffed and the tendons attached to motors as necessary.
Soft Tactile Logic Distributes Decision-Making Throughout Stretchable MaterialTBMG-3704706/01/2020
Soft tactile logic was developed that can make decisions at the material level where the sensor is receiving input, rather than relying on a centralized, semiconductor-based logic system. The resulting device is not quite a robot and not quite a computer but has characteristics of both.
Negotiating the Steering Control Authority within Haptic Shared Control Framework2020-01-103104/14/2020
This paper presents an adaptive haptic shared control framework wherein a human driver and an automation system are physically connected through a motorized steering wheel. By haptic feedback, the driver and automation system can monitor each other actions and can still intuitively express their control intentions. The focus of this project is to develop a systematic model for an automation system that can vary its impedance such that its interaction with a human partner occurs as smoothly as that same interaction would between two humans. To this end, we define four types of conflicts between the human and the automation system. A cost function is then defined to ensures the safety of the collaborative task but also takes account for the assistive behavior of the automation system. We employed a predictive controller based on modified non-negative least square to modulate the automation system impedance such that the cost function is optimized. The results demonstrate that the

Highly Sensitive Sensors Show Promise in Enhancing Human TouchTBMG-3642704/01/2020
People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Surgeons, for example, find that gloves decrease their ability to manipulate soft tissues. Astronauts are also hampered by heavy spacesuits and find it difficult to work with equipment while wearing heavy gloves.
Researchers Develop Ultra-Thin, Ultra-Flexible Electronic MaterialTBMG-3627503/01/2020
Researchers have developed an ultra-thin, ultra-flexible electronic material that could be printed and rolled out like newspaper. The material could be used for the touch-screens of the future.

They demonstrated that the yarn could be used with standard textile manufacturing techniques to create wearable conductive fabric.
VR Helps Amputees ‘Feel’ Prosthetic LimbsTBMG-3563412/01/2019
Scientists have shown that amputees can actually be convinced that the prosthetic hand belongs to their own body. They do this by going beyond the “seeing is believing” idiom based on established research on how the brain identifies what belongs to its own body. Instead of using the sense of sight alone, they used an astute combination of two senses: sight and touch.
Artificial Skin Creates Ticklish DevicesTBMG-3562412/01/2019

Simulating Softness for Haptic InterfacesTBMG-3545611/01/2019
Researchers have developed a formula that enables them to recreate different levels of perceived softness. Based on the results from their experiments, they created equations that can calculate how soft or hard a material will feel based on material thickness, Young’s modulus (a measure of a material’s stiffness), and micropatterned areas. The equations can also do the reverse and calculate, for example, how thick or micropatterned a material needs to be to feel a certain level of softness.
Flexible Sensor Mimics Human Finger SkinTBMG-3550311/01/2019
Artificial skin tactile sensors can feel the similar pressure and vibration felt by human skin. The new sensors can detect more sensitive tactile than the existing ones. The skin-based sensor detects both pressure and vibration at the same time and effectively measures textile. The new sensors also convert the surface roughness of a matter into electrical signals to identify physical stimulations with more sensitivity and accuracy.
Artificial Skin Could Help Rehab, Enhance VRTBMG-3550811/01/2019
Researchers have developed a soft, flexible artificial skin made of silicone and electrodes. The skin’s system of soft sensors and actuators enable the artificial skin to conform to the exact shape of a wearer’s wrist, for example, and provide haptic feedback in the form of pressure and vibration. Strain sensors continuously measure the skin’s deformation so that the haptic feedback can be adjusted in real time to produce a sense of touch that’s as realistic as possible.

Wearable Devices Allow Direct Communication by TouchTBMG-3415504/01/2019
Emergency situations such as trying to escape heavy smoke from fire could leave the sense of touch as the only way to find an exit. Rather than trying to look at a smartphone screen, a smartwatch — alerted by the same alarms — begins “speaking” through the wearer’s skin, giving directions with coded vibrations, squeezes, and tugs with meanings as clear as spoken words. In other scenarios, a surgeon or a pilot might find it useful to have another channel of communication.
Streamlined HMIs do more with less19TOFHP04_0804/01/2019
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.

Biaxial Testing of Medical Devices, Consumer Products, & Drug-Delivery DevicesTBMG-3345212/01/2018
Globally, the use of medical consumables continues to rise due to an aging population and the increasing prevalence of day surgeries. As the use of medical consumables continues to rise, the testing required to ensure that these products meet specifications also increases. Syringes and other medical products with Luer connectors are the most common medical consumables found in the industry, as they are used to connect a wide variety of medical products. Luer connections come in two forms: either a slip or tapered connection, or a threaded locking connection. Most commonly, Luer connectors are used to connect a needle to a syringe body or to connect various types of medical tubing (such as a catheter) to an IV bag, or a needle to catheter.
Ultralight Gloves Provide Realistic Haptic FeedbackTBMG-3338212/01/2018
Engineers and software developers are seeking to create technology that lets users touch, grasp, and manipulate virtual objects while feeling like they are actually touching something in the real world. An ultralight glove — weighing less than 8 grams per finger — was developed that enables users to feel and manipulate virtual objects. The system provides extremely realistic haptic feedback and could run on a battery, allowing for freedom of movement.

Bringing a Human Touch to Modern ProstheticsTBMG-3245808/01/2018
Amputees often experience the sensation of a “phantom limb”—a feeling that a missing body part is still there. That sensory illusion is closer to becoming a reality thanks to a team of engineers at Johns Hopkins University that have created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips.
Design Issues with Wearables From the Perspective of Electromechanical ComponentsTBMG-2970807/01/2018
Life Alert's “I've fallen and I can't get up®!” became one of the most famous infomercial catchphrases in the late 1980s. The company's device, targeted at senior citizens, provided users at the time with the simple, yet revolutionary ability to call for emergency assistance at the push of a button. As you may have guessed, this was one of the first mass-produced medical wearables available on the market.

Force Sensing — An Addition to the Physical Therapy ToolboxTBMG-2900806/01/2018
Undergoing treatment for a physical injury or condition can be a long and frustrating experience. Broken bones, sprains, torn muscles or ligaments, as well as painful conditions that have developed over time, like carpal tunnel syndrome, need customized treatments. Physical therapists could benefit from a measurement-based approach to retraining patients for proper movement and mechanics.
Flexible “Skin” Senses Shear ForceTBMG-2814201/01/2018
To date, it has been difficult or impossible for most robotic and prosthetic hands to accurately sense the vibrations and shear forces that occur, for example, when a finger is sliding along a tabletop, or when an object begins to fall. Some robots today use fully instrumented fingers, but that sense of touch is limited to that appendage, and its shape or size cannot be changed to accommodate different tasks. The other approach is to wrap a robot appendage in a sensor skin, which provides better design flexibility; however, such skins have not yet provided a full range of tactile information.
Tactile Force SensorsTBMG-2724607/01/2017
In the past, surgeons relied on simple tools, training, and their own interpretations to perform their surgical procedures. The innovative minds behind designing new medical devices focused on developing tools that produced quantifiable data, which in turn improved the integrity of the surgical procedure.
Solar-Powered Skin Offers New Possibilities for ProstheticsTBMG-2700406/01/2017
Anew way of harnessing the sun's rays to power ‘synthetic skin’ could help to create advanced prosthetic limbs capable of returning the sense of touch to amputees. Engineers from the University of Glasgow, who have previously developed an ‘electronic skin’ covering for prosthetic hands made from graphene, have found a way to use some of graphene's remarkable physical properties to use energy from the sun to power the skin.

Gesture-Based Controls for Robots: Overview and Implications for Use by Soldiers17AERP05_0605/01/2017
Developing a more effective means to communicate with robotic devices. Army Research Laboratory, Aberdeen Proving Ground, Maryland A future vision of the use of autonomous and intelligent robots in dismounted military operations is for soldiers to interact with robots as teammates, much like soldiers interact with other soldiers. Soldiers will no longer be operators in full control of every movement, as the autonomous intelligent systems will have the capability to act without continual human input. However, soldiers will need to use the information available from, or provided by, the robot. One of the critical needs to achieve this vision is the ability of soldiers and robots to communicate with each other. One way to do that is to use human gestures to instruct and command robots. The use of gestures as a natural means of interacting with devices is a very broad concept that encompasses a range of body movements, including movements of the hands, arms, and legs, facial expressions

Haptic feedback for gesture-control HMI17AUTP04_0404/01/2017
Mid-air gesture controls rely on sophisticated sensing to aid the human-machine interface and help keep drivers' eyes on the road. Gesture control is becoming more commonplace in many of the devices we use in our daily lives, from games consoles, swiping and pinching on mobile phones, to point-of-sale devices such as ticketing systems in train stations. The automotive segment is already adopting gesture control for infotainment systems as well as serving as a human-machine interface (HMI) for subsystems such as the sunroof, climate control and audio. BMW's latest 7 Series and 5 Series offer an HMI system that can detect four different gestures: setting the car's navigation, browsing apps and starting the audio, answering phone calls and controlling the on-board computer. Volkswagen last year announced gesture controls on its Golf and pledges to spread the technology across its model ranges. Other major OEMs have the technology in their product pipelines.

TOUCH TAKES HOLD, switches lend a hand16OFHP10_0710/01/2016
Touch screens are becoming the norm, but knobs and switches are often used to improve operator comfort. System developers are leaving no technology unturned in their effort to boost performance by improving comfort. Touch screens dominate human-machine interface (HMI) development, but rotary knobs and push buttons remain relevant, as do joysticks, which could replace steering wheels. The electronic systems in cabs are evolving to meet expectations of operators used to the convenience of handheld electronics. However, evolving control strategies can't discount user's familiarity with knobs and buttons.

Tactile Sensor Array Design for Triple Seat Detection and Control2016-28-025802/01/2016
In the field of automotive if a vehicle is designed for a particular per person riding capacity considering the aspects of safety, design and power exceeding those limits puts the driver and pillion riders at considerable risk. With a step ahead in this paper we are trying to detect and limit the number of persons sitting on two wheeler. As per the traffic rules in India the maximum number of persons cannot exceed two, apart from the driver only one pillion rider can be carried in behind while driving. Despite of the ban, driver carries more than a single person. Two Pillion riding is also a root of a lot of accidents happening in two wheelers. To make the detection process effective, robust and cost effective a new sensor design was to be put forward. There is no sensor available that could detect the differential load over the larger area at effective cost. To cater to this problem Bubble based tactile based sensors were developed and checked for this application. An array of Bubble

Distributed User Interface Management System for Interactive Collaborative EnvironmentsTBMG-2389002/01/2016
The Ground Systems Development and Operations (GSDO) Smart Firing Room Project aims to create a firing room using cutting-edge technologies of today that are expected to be the state-of-the-art for the 2020s. One aspect of this project is providing a seamless Interactive Collaborative Environment (ICE) across a diverse array of user-facing devices — numerous screens of varying sizes, personal mobile devices, and natural user interface (NUI) sensors for multi-touch, gesture, and voice inputs. Applications accessible through the ICE are expected to provide Distributed User Interfaces (DUIs) that support collaborative features such as sharing applications with remote users, multi-user interaction for collaborative editing, and modular User Interfaces (UIs) to support customized workspaces spread across multiple devices. Using current technologies, developing an application with a DUI supporting such a wide variety of platforms is extremely costly due to the tight coupling between UIs

Controlling Execution Sequence Using Tactile-Classification During Manipulation by a Humanoid RobotTBMG-2240807/01/2015
It is necessary to track system state during robotic manipulation. System state is defined to be manipulator and environment configuration. Without tracking, the robot is ignorant of the outcomes of its actions. State tracking enables the robot to respond to sub-task failures. Tracking system state is difficult for complex robots that incorporate hundreds of individual sensor signals. It is difficult to determine which signals are relevant and which are not, and to find low dimensional representations of system state.

The Touch Screen RevolutionTBMG-2154502/01/2015
Touch screens are slowly but surely creeping into every aspect of our day-to-day lives. It’s not unlikely that you wake up to a cellphone alarm, adjust the room temperature on a thermostat, change the radio station in the car, and even start the washing machine using only a touch screen. A decade ago, we wouldn’t have used a touch screen for any of these tasks, but today it’s commonplace. To understand the impact of touch screens on test and measurement, you must first know the difference between resistive and capacitive touch screens, and the impact smartphones have had on touch screen implementations.
