Abstract:

In one aspect, a device includes a processor, an infrared (IR) detector accessible to the processor and that receives signals from a primary IR emitter on a hand-held device and a secondary IR emitter on the hand-held device, a projector accessible to the processor, a transceiver accessible to the processor, and storage accessible to the processor. The storage bears instructions executable by the processor to use a location of the secondary IR emitter as sensed by the IR detector and orientation data of the hand-held device received from the transceiver to extrapolate a handwriting projection reference. The instructions are also executable to use the handwriting projection reference to project handwriting onto a projected whiteboard.
