This document discusses a tangible display called Twiz. Twiz is a small, low power device that can be worn or embedded in objects to provide haptic feedback and receive input from sensors. It uses Bluetooth Low Energy to communicate data from integrated sensors to apps. The document outlines Twiz's capabilities for uses in areas like art, music, home automation, and human-computer interaction. It also describes the iterative development process used to design and manufacture Twiz, from initial prototypes to solutions for miniaturization and low power consumption.
