VirtuaLimb - Technical Document

VirtuaLimb: Box & Block Test: A mobile app that lets lower-arm amputees take the Box & Block test in Augmented Reality using a virtual arm. There's a Problem: In order to relieve debilitating phantom limb pain and increase the chance of prosthetic adoption, Amputees must exercise the muscles closest to the limb that was lost early after amputation. Our Solution: We will create an experience where a lower arm amputee can control an Augmented Reality arm that is projected over the amputation point to complete a virtual recreation of the Box & Block manual dexterity test. Our Tech: We use four primary technologies to make the magic happen: the Myo gesture armband, the Soliton Reach mobile tracking system, Vuforia's vision platform, and the Unity game engine. The Myo gesture band allows users to move and control the virtual arm in order to pick up and release virtual blocks; The Soliton Reach allows the program's virtual arm to precisely follow the movement and orientation of the user's physical arm; Vuforia lets the user move the playspace anywhere in the room and allows the user to examine the playspace in a 360X180-degree viewpoint; The Unity engine allows us the flexibility to quickly create and test experiences in AR, VR, and MR (mixed reality). Our Users: 2 Million people in the U.S. have an amputation; Target audience are males 27-60 years old; 68% of upper-limb amputations occur from trauma; By 2050 the U.S. amputee population will double. Project Innovations: Free full body movement - no wires; Designed to improve the adoption of prosthetics; Phantom pain relief amputees can have at home; First Myo game made specifically for amputee. Platform: Android Mobile AR
