BigScreen

BigScreen is a multi-device display system that combines multiple phones, tablets, or laptops into a single large screen.

Concept

Place several devices side by side and BigScreen treats them as tiles in a larger display. Content flows seamlessly across device boundaries, effectively creating an ad-hoc large monitor from whatever screens are available. Use cases include presentations, group viewing, and collaborative work.

Technical Approach

Devices connect via local network and synchronize their displays using a coordination server. Each device renders its portion of the overall canvas. Calibration handles different screen sizes and resolutions. Touch input on any device is mapped to the global coordinate space.

Status

Hackathon concept from the MIT era.
