SONY SMART TENNIS SENSOR
They say the CIA can reconstruct your conversations using an office object, turning vibrations into a waveform of you slagging off your manager. Knowing this makes
a sensor that only tells you that you hit a ball seem underwhelming. Until you learn it can measure where on the strings you hit the ball, along with swing and ball speed. It knows its forehand smash from its backhand slice, and all the stats can either be saved or viewed in real time via an Android or iOS app.
