Images from two handheld projectors get interactive

The system, suitable for games, education and a variety of other applications, is self-contained in special handheld devices.

According to a statement, no external cameras or other sensors are required, which enables people to use the projectors to interact with each other anywhere and at anytime.

It is claimed that SideBySide can be used also to exchange contact information, or even share data files.

‘Smartphones have made it possible for us to communicate, play games and retrieve information from the web wherever we might be, but our interaction with the devices remains a largely solitary, single user experience,’ said Karl DD Willis, a PhD candidate in computational design at Carnegie Mellon and a lab associate at Disney Research. ‘Now that handheld projectors have become a reality, we finally have a technology that allows us to create a new way for people to interact in the real world.’

The handheld projectors are hybrid devices that emit visible and infrared light, and contain a camera for monitoring the projected images, a ranging sensor and an inertial measurement unit.
