Project Overview


Principal Investigator:   Derek Kamper, PhD

Co - Investigators:  Daria Tsoupikova, MFA (Co-PI)

Synopsis/Goals of the Project

To develop and evaluate a multi-user virtual reality (VR) environment for training upper extremity motor control after stroke

Project Aim #1: Create the VR environment

Project Aim #2: Evaluate user engagement

Project Aim #3: Test impact on training motivation in home

Major Accomplishments


A virtual reality environment for multi-user exercises

Virtual Reality Home Hand Therapy


Access to clinical therapy can be limited by transportation issues, scheduling conflicts, or insurance restrictions.  Yet, we know that repetitive, targeted movement practice is crucial for successful rehabilitation following stroke or other injury.  We believe the solution is to provide greater access to therapy in the home.  Thus, we have developed a multi-user virtual reality (VR) environment intended to promote home rehabilitation.  

Therapists, family members, and friends can join the stroke survivor in the virtual environment even though they may be physically separated by hundreds or thousands of miles.  Each participant controls their own avatar in the VR environment through corresponding movement of their body.  The avatars can interact with virtual objects in the three-dimensional environment, as well as with each other, in real-time.  

Through the different virtual scenarios, such as a food fight, painting in the air, and hitting a ball back and forth, the support group can encourage and guide the stroke survivor to practice challenging arm movements to different parts of the arm workspace.  We have successfully tested the system in the laboratory and are now in the process of moving the system into user’s homes.
