Search Light Interactions with Personal Projector

Mobile projectors are an emerging trend and becoming ever more present in the consumer market.One main concern is how this resource will be used and exploited.The act of physically holding the projection device while interacting is uncommon and potentially beset with many issues.In this paper we present a mobile application, which uses the searchlight metaphor as a novel means of navigating though information space, potentially of limitless size.In addition to the searchlight navigation technique we have developed a number of input techniques which challenge the classic button press interaction with a number of intuitive gestures which complement the interaction style.We present our findings from a user study in which the usability of each technique was evaluated, we also propose several heuristics for mobile projector interaction design.
