InerTouchHand System - iTH - Demonstration of a Glove Device with Distributed Inertial Sensors and Vibro-tactile Feedback

Abstract

The InerTouchHand System shows the usage of an instrumented glove-like device for HMI-Human Machine Interaction applications. We explored the use of distributed inertial sensors and vibro-tactile stimulators on the hand. Distributed Inertial Measurement Units (IMUs) can be used to infer structure and reconstruct 6D pose of nodes, as well as relative motion. Our system uses MEMS IMUs on each fingertip for providing relative angular pose by using gravity as a vertical reference for acceleration measurements. Although not always fully observable it can be complemented by the IMUs’ gyro rotation and magnetometer measurements. When combined with vibrotactile stimulators a hand worn device or glove can provide spatial aware feedback. At exp.at’13 (2nd Experiment@ International Conference) an interactive demo presented InerTouchHand (iTH), the hand device for gesture recognition and HMI with touch feedback.
