Wearable Assistive Devices

An estimated 1.5 million individuals in the United States are hospitalized each year because of strokes, brain injuries and spinal cord injuries. Severe impairment such as paralysis, paresis, weakness and limited range of motion are common sequels resulting from these injuries, requiring extensive rehabilitation. This project is developing invisible sensing systems (using textile-based capacitive sensor arrays and micro-doppler radars) embedded into bed sheets, pillows, wheelchair pads, and clothing, for environmental control and physical therapy for such paralysis patients. The system detects gestures regardless of evolving environmental and patient conditions and provides explicit real-time feedback to the user. Through the use of low-cost and ultra-low power capacitive sensing and micro-radars built into headgears, the system reduces hospital visits and therapy costs.

Embedded Hardware Security

We study power-supply sidechannel leakage on FPGAs and ASICs through hardware experimentaion and simulation. Our goal is discovery of new side-channel volnerabilites along with techniques and EDA tools for coutermeasures in embedded systems. We are espcially focused on security for low-power embedded systems.

Human Assisted Computer Vision

Sidewalk navigation for the visually impaired, especially those who use wheelchairs, can be a daunting task. While laws advocate proper standards for accessibility-compatible sidewalks, several develop cracks and obstacles over time and many have curbs and steps. Emerging wearable devices such as Google glasses provide an opportunity for continuous vision-based systems that can navigate individuals around accessibility issues on sidewalks. Unfortunately, real-time vision-based navigation systems are scarce. The problem stems from a basic limitation of vision algorithms---without a priori contextual information on a scene, it is impossible for a vision algorithm to search for objects of interest. To address this critical problem, this project proposes a cyber-physical system that augments machine vision algorithms with a priori contextual information collected using human crowdsourcing. The key idea is to use humans in conjunction with custom system build a rich library of information on scenes with accessibility issues. This library can then be used to design context aware machine vision algorithms that can efficiently detect accessibility problems in real-time.
