Abstract:

A classroom configuration is described that includes a computer having a wireless communications interface and a plurality of student workstations. The workstations each include a work surface, a projecting device mounted proximate the work surface and operable for projecting images onto the work surface, a light emitting device, a tracking device mounted proximate the work surface and operable for capturing the image projected onto the work surface and for tracking movement of the light emitting device, and a processing device communicatively coupled to the projecting device and the tracking device. The processing device includes an interface operable for communicating with the computer via the communications interface. At least one of the processing device and the computer are programmed to receive data associated with movement of the light emitting device via the tracking device and the processing device and generate data, for transmission to the projector via the processing device, the generated data indicative of the movement of the light emitting device for transmission onto the work surface and the projected image by the projecting device.
