Introducing TongueTap: Revolutionary Wearable Tech Control
TongueTap is an innovative technology that allows you to control wearable devices through tongue gestures, without the need for hands, eyes, or complex interfaces. This technology is a collaboration between Microsoft Research and the Georgia Institute of Technology, and it’s designed to make your interaction with head-worn devices seamless and intuitive.
How Does TongueTap Work?
By integrating sensors from two commercial headsets, TongueTap captures tongue movements with impressive accuracy. The headsets are equipped with IMUs and PPG sensors, and one includes additional EEG, eye tracking, and head tracking sensors. Data synchronization is achieved using the Lab Streaming Layer (LSL), ensuring precise gesture recognition.
Research Insights and Practical Applications
The research highlighted that the IMU sensor, particularly when placed behind the ear, was highly effective in recognizing tongue gestures, achieving up to 94% accuracy in combination with other sensors. This discovery suggests a cost-effective and efficient method for gesture detection that could be integrated with existing technologies.
The potential applications for TongueTap are vast, with the most promising being the control of Augmented Reality (AR) interfaces. The researchers are continuing to explore the capabilities of TongueTap, aiming to refine its use in more realistic environments and compare it with other interaction methods.
