Virtual Hemiparesis Rehabilitation Game for Stroke Survivors

Researchers: Luke Buschmann, Sri Kurniawan. In collaboration with Cabrillo College’s Stroke and Disability Learning Center.

Stroke can leave survivors with some form of hemiparesis (weakness of one side of the body). Virtual rehabilitation in the past decade has shown higher success than traditional rehabilitation. It improves the patient’s experience and can allow for clinical rehab without a clinician present. Research in non-virtual rehabilitation shows that constraint induced movement therapy is very effective in treating hemiplegia. In this therapy, the patient’s strong side is physically constrained using a mitt or hand splint on the non-affected limb, forcing the patient to utilize their weaker limb for daily activity.

Vibrotactile Guidance for Wayfinding of Blind Walkers

Our project’s goal was to test the feasibility of a novel vibrotactile guidance system, in the form of a belt, for helping blind walkers with wayfinding by enabling them to receive haptic directional instructions without negatively impacting their ability to listen and/or perceive the environment. We evaluated the belt interface in a controlled study with 10 blind individuals and compared it to an audio guidance system. The experiments were videotaped and the participants’ behaviors and comments were content analyzed. Completion times and deviations from ideal paths were also collected and statistically analyzed.

Brain-Training Software for Stroke Survivors

We investigated the feasibility of using web-based brain-training software to help stroke survivors and, in general, individuals with cognitive impairments. For this purpose we observed and interviewed stroke survivors to get a better understanding of the technologies that they feel are helpful, as well as examine the effectiveness and limitations of such technologies. From this, we compiled an informal set of design guidelines for rehabilitation software aimed to help stroke survivors improve their cognitive skills. To validate the guidelines and see if new ones emerged, we developed a low-fidelity prototype of a web-based brain-training software and tested it with five participants to check its feasibility as a cognitive rehabilitation software solution.

LASSIE

LASSIE (Live-in ASSistance for Independence and Eldercare)

Image for LASSIEThis LASSIE robot is designed to be a monitoring assistive living robot, which is low cost and can be steered over the Internet by family member to remotely monitor and help assess the well-being of an older relative living alone. A commercially available iRobot Create platform was used as a starting point for the Assistive Living Robot, however the system could potentially be used on another robotic base. Our system (i) takes advantage of commercially available systems to reduce development cost and effort, (ii) acts as a video and audio communication tool between older persons and their family members or caregivers and (iii) can analyze the video feed to detect heart rate and breathing rate. The proposed system could be integrated with in-home monitoring sensors (Smart Grid, Professor Patrick Mantey), which could be the trigger for alerting family members that an out of ordinary event is occurring, therefore, our robot could be woken up and sent to be used as over the Internet watchful eye.

Digital Birth

Labor and childbirth is a multidimensional experience for which it is difficult to prepare (without having done it before). It has been shown that emotional, informational, and physical support is key in shortening labor, increasing maternal happiness, and decreasing the need for unnecessary interventions during labor. This mobile (iPhone) video game training tool aims to train birth partners about the stages of labor and ways to support a first-time mom.
