'EchoFlex' - Wearable Device Uses Ultrasound to Recognize Hand Gestures
From: Robotics & Automation - 10/13/2017

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," 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%.
