Improving Gestural Interaction With Augmented Cursors

Gesture-based interaction has become more affordable and ubiquitous as an interaction style in recent years. One issue with gestural pointing is the lack of accuracy with smaller targets. In this paper we propose that the use of augmented cursors - which has been shown to improve small target acquisition with a standard mouse - also improves small target acquisition for gestural pointing. In our study we explored the use of Bubble Lens and Bubble Cursor as a means to improve acquisition of smaller targets, and compared it with interactions without them. Our study showed that both methods significantly improved target selection. As part of our study, we also identified the parameters in configuring Bubble Cursor for optimal results.
