Lantern

Lantern is a small portable device which consists of five pairs of LEDs installed on a stub-shape PCB covered by a blurry plastic cylinder, and one microprocessor to control the LEDs. Each Lantern shows the status of one collaborator. The user can turn and press the Lantern, which respectively result in changing color and switching blinking mode. Every user interaction is recorded and can be transmitted through the USB port for offline analysis.
