'EchoFlex' - Wearable Device Uses Ultrasound to Recognize Hand Gestures
Researchers from the UK"s University of Bristol have found a way to implement ultrasound imaging technology into wearable devices. "??Ultrasound imaging has remained under-explored in the HCI community despite being non-invasive, harmless, and capable of imaging internal body parts, with applications including smart-watch interaction, prosthesis control, and instrument tuition,"?%9D they wrote in a paper for the 2017 CHI Conference on Human Factors in Computing Systems. Their gesture recognition algorithm combines image processing and neural networks to classify ten discrete hand gestures with an accuracy above 98%.
