Gridfinite Possibilities: the Illuminated Button Matrix as Input and Output Device

Abstract

Gridfinite Possibilities explores the interface of an illuminated 8x8 button grid as simultaneous input and output device. Individually addressable LEDs under a silicone cube button pad serve as a platform for creativity in 8x8 resolution. The demonstration uses a set of RFID cards to allow the user to reconfigure the device's button programming mode to play a variety of classic grid-based logic and low-resolution games on the system. This paper reviews existing button matrix devices and considers theory of button pushing and remapping. Initial user feedback aligns with a proposal for further study on user cognition in reaction to reassigned buttons on a control device.
