Project Details
- "We have developed a very simple retrofit to a large display surface that enables knocks or taps to be located and characterized (e.g., determining type of hit - metallic tap, knuckle tap, or bash - and intensity) in real time."
- This is achieved by analyzing the waveforms captured by 4 piezoelectric transducers (one mounted in each corner of the surface) and a dynamic microphone (mounted anywhere on the glass) in a digital signal processor. Differential timing yields the position, frequency content infers the kind of hit, and peak amplitude reflects the intensity.
