Evaluation of three input techniques for selection and annotation of physical objects through an augmented reality view

This paper presents results from a study into the usability issues of two tasks (selection and annotation of a physical object) for users operating mobile augmented reality systems. The study compared the following three different modes of cursor manipulation: a handheld mouse, a head cursor, and an image-plane vision-tracked device. The selection task was evaluated based on number of mouse button clicks, completion time, and a subjective survey. The annotation task was evaluated based on accuracy of the annotation, completion time, and a subjective survey.
