We present an intelligent interface system which includes 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 a use of various public 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 pre-cursor to all other subsequent actions. We propose a new selection algorithm which 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 about 62.6%.
