Ultrasound 3-D sensing tech for improved gesture recognition - CES 2016

Dave Horsley from Sharp Microsystems introduces a novel ultrasound technology using micro machined ultrasonic transducers. He explains that ultrasound consists of high-frequency pressure waves, which are inaudible to humans. The technology uses multiple transducers to emit pulses and measure echoes, similar to GPS triangulation, allowing for precise range measurements. This innovation adds a third dimension to device interaction, enabling users to interact with devices without physical contact.

Explain how the concept of triangulation is applied in the context of ultrasound sensors.
