Towards a usable stereoscopic augmented reality interface for the manipulation of virtual cursors

The combination of augmented reality (AR) systems and stereoscopic display devices has created a powerful tool with which to "supplement" our view. One application for such systems is for the augmented teleoperation of unmanned vehicles, deployed in remote or hazardous environments. Research in this area has highlighted the need for accurate 3D measurement techniques - such as through the use of virtual cursors. This paper describes our work in the development of an AR interface designed to assist the accurate selection of position in 3D space. We describe some preliminary experimental work using virtual cursors before discussing how we believe depth cues can be utilized to allow a user to make a more informed judgment of depth in unprepared environments. It is expected that the guidelines outlined in this report will be used as a benchmark for the development of further 3D ARA cursors.
