Scanning angles for directional pointing

ABSTRACT

The present study was performed in order to get a better understanding of the influence of the scanning angle interval on navigation performance, gestures and strategies in a more realistic outdoor setting. Results indicate that users are able to handle a wide range of angle intervals. We observe different gestures and strategies and provide recommendations for suitable angle intervals. Our observations also support the notion that using this type of pointing gesture for navigation is intuitive and easy to use.
