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.

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.

Haptic Guidance and Training Using OpenWrist and CUFF

This research project focuses on delivering haptic guidance through cutaneous (skin stretch and squeeze) methods to help train people for new tasks. Haptic devices are tremendously useful for giving customized feedback during training. These devices can simulate forces associated with real-world tasks or provide guidance forces that help users to complete the task more effectively or accurately. It has been shown, however, that providing both task forces and guidance forces simultaneously through the same haptic interface can lead to confusion and worse performance.

Real-Time Performance Assessment and Feedback for Manual and Robotic Surgery Platforms

Building competency in performing minimally invasive procedures is a significant effort, as trainees must acquire both procedural knowledge and manual dexterity to perform complicated tasks. If done correctly, these procedures can lead to shorter post-operative periods and fewer complications than open surgery. This is especially true in the endovascular domain, which require surgeons to navigate flexible guidewires and catheters across blood vessels to perform a variety diagnostic and therapeutic procedures such as heart valve replacements and aneurysm repair.
