Abstract

A software controlled user interface and method for a head-mountable device equipped with at least one display or connectivity to at least one touch pad. The method can scale between displaying a small to large number of different eye gaze target symbols at any given time, yet still transmit a large array of different symbols to outside devices. At least part of the method may be implemented by way of a virtual window onto the surface of a virtual cylinder, with touchpad or eye gaze sensitive symbols that can be rotated by touchpad touch or eye gaze thus bringing various groups of symbols into view, and then selected. Specific examples of use of this interface and method on a head-mountable device are disclosed, along with various operation examples including transmitting data including text, functionality in virtual or augmented reality, control of robotic devices and control of remote vehicles.
