TWO STEP GAZE INTERACTION

摘要

A computer system can be controlled with non-contact inputs, such as eye-tracking devices. A computer can enlarge a portion of a display adjacent a first gaze target in response to detecting a first action (e.g., pressing a touchpad). The computer can then allow a user to position a second gaze target in the enlarged portion (e.g., by looking at the desired location) and perform a second action in order to perform a computer function at that location. The enlarging can allow a user to identify a desired location for a computer function (e.g., selecting an icon) with greater precision.
