Cubic Keyboard for Virtual Reality

Abstract

We developed a cubic keyboard to exploit the three-dimensional (3D) space of virtual reality (VR) environments. The user enters a word by drawing a stroke with the controller. The keyboard consists of 27 keys arranged in a 3 x 3 x 3 (vertical, horizontal, and depth) 3D array; all 26 letters of the alphabet are assigned to 26 keys; the center key is blank. The user moves the controller to the key of a letter of the word and then selects that key by slowing movement.
