Apple may be working on pico-projector technology that could be used with its iPhone and Mac products according to a patent filing discovered by UnwiredView. The patent, titled “Projected display shared workspaces,” shows how one might be able to use an iPhone or Mac to project content onto a larger open space, such as a wall, by attaching a small pico-projector. In addition, users could control the projection using multitouch gestures on their iPhone screen or Mac trackpad. The patent reminds us of AT&Ts LG eXpo, which had its own projector accessory but wasn’t much of a hit with consumers. Read on for a second image from Apple’s patent.
