A patent uncovered by Patently Apple reveals Apple’s intention to eventually include a mini projector in the iPhone and iPad and a pico projector-like accessory for MacBooks.
But the most incredibly novel and useful part of the patent description isn’t the projector. It’s the advanced gesturing analysis that would be used in conjunction with the projector to interpret shadow or silhouette movements when presentations (or even workspaces) are displayed in a dark environment.
In Patently Apple’s words, “The level of detail associated with this patent would suggest that Apple’s development teams are moving full steam ahead on the projection system project.”
