Amazing smartwatch mod could hold key to user interfaces of the future
By altering the sampling rate of a smartwatch accelerometer, the researchers have managed to make it communicate with a computer in an entirely new way. By upping the sampling rate frequency by nearly 3900 percent, from 100 Hz to 4 kHz, the modded watch can pick up subtle bioacustic signals, allowing it to perform such tasks as help you tune a guitar by feeling the vibrations of each string tightening or loosening through the hand you're turning the pegs with. The mod is able to differentiate between so many distinct “gestures”, that the possibilities for its implementation in user interfaces are close to infinite. It can tell whether you're snapping your fingers, tapping your palm, wrist, or forearm, rotating your hand, and many other gestures which could be used for human-computer interactions.
The scientists at the Carnegie Mellon University have made a cool proof-of-concept video showcasing the mod's surprising agility at guessing what actions the user is performing. Watch it below:
