Visual Design, Interaction Design, and Tangible Media

X Screen uses shadow, light, and movement to create dynamic, abstract visual form.

An ultrabright led mounted on a servo motor is installed in the rear wall of a cardboard box; this led serves as a moving light source, offering varying degrees of vertical projection.

A piece of cardboard, carved in the shape of the letter 'x' sits on a rotating platform.

A servo motor installed in the base of the box allows for clockwise and counterclockwise movement of the platform. A protoboard made of translucent yellow plastic serves as the screen.

Both servos are controlled by a BX24 microcontroller, which resides outside the box.

X Screen provides a visual output for fellow classmate Karmen Franinovic's Taktile InBox, which explores touch as interface. X accepts serial input via this phone jack.
