Touchscreen is an audio exploration of surface acoustic waves that emanate from electronic visual displays. Touchscreen replaces the touch of the human finger on the screen with an ultrasonic sensor. This sensor functions as a conductive input to capture the sonic activity of the various touchscreen devices.

Each track title references the use of a specific device or software. A series of GUI experiments were performed on the devices including: text/pix messaging, data synchronization, bonus level gameplay, and a cash deposit.

The audio addresses the presence, location, and detection of ultrasonic waves and electro-static fields that pass over touchscreen panels. Touchscreen experiments with the event of touch through a series of freestyle-tapping techniques, gestural signal processing, and distorted cadence structures.
