Karl D.D. Willis, Ivan Poupyrev, Scott E. Hudson and Moshe Mahler, researchers at address Disney Research (Pittsburgh – Pennsylvania ), present SideBySide, a stunning system designed for ad-hoc multi-user interaction with handheld projectors.
SideBySide does not require instrumentation of the environment and can be used almost anywhere. It uses a device-mounted infrared (IR) camera and a novel hybrid visible/IR light handheld projector.
Multiple users can play projected games together by creating ad-hoc gaming spaces. Exchanging digital content, such as personal contact information or media files, can be initiated without any infrastructure.
SideBySide software platform tracks multiple independent projected images in relation to one another using invisible fiducial markers projected in the near-IR spectrum. The resulting system allows a broad range of new interaction scenarios where users are not tied to a fixed location.
Interaction scenarios for education allow teachers and students to study together using a shared information space. Most importantly, these interaction scenarios can happen anywhere – in an elevator up to a business meeting, in a child’s bedroom after lights out, or in the hallway outside a classroom.
