Application examples

1. Attach an airbag to the end of the tube and create a "squeeze" controller or an alternative to the bagpipe wind controls. Add TouchMini or TouchMiniOn sensors for buttons, a Slide for octave control and a GForce3D to capture body movements.
2. Attach the tube to a pillow filled with air and make music while you sleep - better yet, create a playpen full of such pillows and use the sensor signals for audiovisual effects.
3. Combine the Air sensor with a Hot, Humid and Light to create a full-blown climate control system. Add Switches to control water valves.

Software support		Our SensePlay software is a very easy way to quickly map sensor data to (sequences of) sounds, images and videos using a drag & drop user interface. Our EditorX software allows you to configure the digitizer to process and map the sensor data of multiple sensors simultaneously. Our Link software allows you to receive the sensor data from the digitizer and use your computer to view, calibrate, record, process and map the sensor data of multiple sensors simultaneously. Our SensorX software allows you to receive the sensor data from the digitizer and use your computer to view, calibrate, record, process and map the data of a single sensor.
