Abstract

This chapter presents an intelligent interface system, including a new gesture-based wearable input device called iThrow as a main user interface for mobile devices, and an infrastructure helping users be aware of and make use of various electronic devices in user-friendly manners. In this kind of intelligent interface system, selecting an object among multiple ones is one of the fundamental functions because it is a precursor to all other subsequent actions. We propose a new selection algorithm that improves selection speed by adaptively resizing the objects’ angular widths. Results show that the proposed algorithm outperforms the ray-based selection technique in selection speed by about 62.6%.
