Movement-Tracking Threads
August 3, 2021 | Terry Sharrer
“Human machine interfaces that can track head motion will result in advances in physical rehabilitation, improved augmented reality/virtual reality systems, and aid in the study of human behavior. This paper presents a head position monitoring and classification system using thin flexible strain sensing threads placed on the neck of an individual. A wireless circuit module consisting of impedance readout circuitry and a Bluetooth module records and transmits strain information to a computer.” The scientists at Tufts University who developed this interface report it is 92% accurate in tracking movements.
