Abstract

Smartphones and handheld devices are increasingly being used in interactive applications beyond their conventional touchscreens. For example, tangibles allow users to interact with mobile devices using physical objects both on screen and around the device. Similarly, there is a growing class of auxiliary devices that require a smartphone to be docked, transforming an otherwise simple object into something with rich interactivity. However, these auxiliary devices still require numerous components, including mechanical mechanisms, PCBs, and sometimes batteries. This increases manufacturing costs, and reduces physical robustness.
