AirTimer is a research project on exploring alternative approaches for the most common ways of human computer interaction: The device, a clock-like countdown timer, is not operated by any buttons, keyboard or touchscreen, but by in-air gestures only. Its user feedback is not given on a screen or on a LCD, but only by a simple ring of 60 LEDs. For prototyping purposes we used a simulation of the LED ring on a 24″ screen.

The project was part of the course Interaction Engineering at the University of Applied Sciences Augsburg.
