Computing devices can seamlessly recognize one another as they join and leave a wireless network, but users often experience difficulty identifying a desired device from a continuously changing list of devices surrounding them. This paper describes our custom implementation of a stylus and tags that enable users to rapidly identify devices in dynamic environments. Our system utilizes a natural pointing gesture to identify a device, and subsequently transfer data over a wireless network. Keywords Pointing, gesturing, face-to-face, collaboration, handheld computer, PDA, infrared (IR) tag
