Promoted as low-cost components, the Virtu and Virtu18 ultrasonic sensors are now available with analog outputs. Both are dual-mount, barrel-style sensors with a sensing range from 50 mm to 508 mm ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.
