Could you build this?
Partial The UI and gesture bindings are simple, but implementing active acoustic echolocation / Doppler sensing via speaker chirps and microphone signal processing requires specialized DSP algorithms.
What it would actually take: Requires continuous emission of inaudible high-frequency acoustic waves (18-22 kHz) through CoreAudio, synchronized with real-time mic input analysis via FFT and Doppler shift processing. The hard part is filtering out room acoustics, ambient noise, and speaker distortion to extract hand distance and gesture velocities reliably at low latency. Requires applied digital signal processing and acoustic engineering expertise.
