Hands Free Interaction with Virtual Information in a Real Environment: Eye Gaze as an Interaction Tool in an Augmented Reality System

Abstract

Eye contact in human conversations is a natural source of information about the visual attention of people talking, and also indicates who is speaking to whom. Eye gaze can be used as an interaction method, but gaze tracking can also be used to monitor a user’s eye movements and visual interest. This paper describes how gaze-based interaction can be used and implemented in an Augmented Reality (AR) system. The results of the preliminary tests of the gaze-controlled AR system show that the system does work, but that it needs considerable development and further user studies before it can be a realistic option in real end user settings.
