Second Skin: Motion capture with actuated feedback for motor learning

Abstract

Second Skin aims to combine three-dimensional motion tracking with real-time tactile feedback for the purpose of improving a user's motor-learning ability. Body and limb movements are tracked in 3D as a user performs an action, and the user is given automatic, real-time tactile feedback to aid in the correction of movement and position errors. The key areas of the system involve the development of a robust optical motion tracking system that can be used in a wide range of environments and lighting conditions, and an effective tactile feedback method capable of delivering information to the user to indicate how to correct errors in body and limb position. Since a number of components of the motion tracking and tactile feedback systems must be bound to the user's body, another important goal is the design of a lightweight and minimally inhibitive wearable suit to contain all of these elements.
