Chirp: The chip that could make wearable tech a whole lot easier to use | Digital Trends.
I am so excited about this technology! Finally a chance to look like a witch casting spells. Wearable tech made feasible with developing gesture based technology!
The researcher’s tiny technology, called Chirp, comprises an ultrasound chip and an electronics chip (right) that work together to interpret gestures in three dimensions, or in other words, in the air.
The system uses small acoustic resonators, or ultrasound transducers, that send out ultrasonic pulses. These echo off anything within a meter of the device, such as your hand, with the technology able to interpret various gestures and convert them into actions on the gadget.
With Chirp inside it may look like you’re trying to cast a spell on an invisible friend, but at least the device’ll remain on your face.
