Sensory Feedback for Smart Prosthetics

Though mechanical aspects of upper-limb prosthesis technology is rapidly advancing, these devices lack a sense of touch required for dexterous manipulation and exploring environments. We aim to address this concern by developing non-invasive technology to provide missing touch sensations in prosthetic limbs via sensory substitution with modular add-on devices separate from the prosthesis.

Sensory Feedback for Smart Prosthetics

Researchers aim for 'direct brain control' of prosthetic arms

Engineers work to design prosthetic arm that allows amputees to feel what they touch

http://www.media.rice.edu/media/NewsBot.asp?MODE=VIEW&ID=15983&SnID=1928...

Engineering researchers at four U.S. universities are embarking on a four-year project to design a prosthetic arm that amputees can control directly with their brains and that will allow them to feel what they touch. While it may sound like science fiction, the researchers say much of the technology has already been proven in small-scale demonstrations.

The research at Rice University, the University of Michigan, Drexel University and the University of Maryland is made possible by a $1.2 million grant from the National Science Foundation's Human-Centered Computing program.

Fluidic Haptic Wearable Devices

Our sense of touch offers a useful mode of communication through haptics that can augment the often-crowded visual and auditory pathways, but haptic devices have yet to be fully integrated into garments and other soft wearables in a way that maintains the compliance and comfort of everyday clothing, resulting in a barrier to widespread adoption.

Affective Haptics for Emotion Regulation and Evocation

Affective haptics is an emerging field that is dedicated to the creation, analysis, and evolution of systems for capturing, conveying, and rpocessing emotions through tactile sensation. This project is focused on the application of affective haptics in emotion regulation. Emotion regulation techniques are utilized in mental health treatments for mood and anxiety disorders. We are utilizing haptics with emotionally evocative qualities to act as a biofeedback mechanism for those utilizing these techniques.

Snaptics: Low-Cost Open-Source Hardware for Wearable Multi-Sensory Haptics

There has been growing interest in using haptic devices to enhance virtual experiences or to increase the amount of information transferred to a user by wearable devices. As such, the haptics community has proposed a wide range of wearable haptic devices, often featuring multi-sensory cues that convey vibration, squeeze, twist, or skin stretch.

MISSIVE: Multisensory Interface of Stretch, Squeeze and Integrated Vibration Elements

MISSIVE - Multisensory Interface of Stretch, Squeeze and Integrated Vibration Elements

MISSIVE incorporates skin stretch, squeeze and vibration cues presented simultaneously to the user in distinct patterns. The use of multisensory cues allows us to design large discrete cue sets while maintaining a small and wearable form factor. With MISSIVE, we demonstrated language transmission via haptic phonemes, or units of sound encoded as haptic cues consisting of vibration, radial squeeze, and lateral skin stretch components.

Multi-Sensory Haptic Perception

Multi-sensory haptic cues have the potential to transmit a wider variety of information in the same amount of time as single-sensory haptic cues. However, these cues also interfere with each other, causing them to feel less salient to users. As it is critical that the multisensory cues transmitted to a user are conspicuous, we use the AIMS Testbed to investigate the perception of multisensory haptic cues and how this perception changes when cues are modified.
