A personal-area network of low-power wireless interfacing devices for handhelds: system and hardware design

ABSTRACT

Handhelds, such as smart-phones and Pocket PCs, have the potential to become the computing, storage, and connectivity hub, or Digital Hub, for pervasive computing. However, their current interfacing paradigms fall short of achieving this goal. To meet this challenge, we present the system and hardware design for a Bluetooth-based personal-area network (PAN) of low-power wireless interfacing devices. The network consists of a wrist-watch, single-hand single-tap multi-finger keypad, smart speech portal, and GPS receiver. These devices serve a handheld in a synergistic fashion, collectively providing the user with immediate and more natural access to computing power and enabling more and better services.
