Movement Record & Visualizer

/////////////////////////////////////////////// Video //////////////////////////////////////////////////

///////////////////////////////////////////////////////////////////////////////////////////////////////////

————————————————————————————————

The recorder part keep track the time you spend in each space range in a time period, and visualize you time and space through the lights.

The longer people spend away from the device, the longer short LEDs blink.

The longer people spend near to the device,  the longer tall LEDs blink.
