Samsung thinks it has a possible solution to the problem of tiny, hard-to-read smartwatches: a projector. The company has filed a patent for a smartwatch that projects a larger screen onto the user’s hand or forearm.
A projector smartwatch would work by using an image projector, a camera that captures the interactions with the projected screen, and a processor that controls and connects the two. Sketches from the filing show menu image options being projected across the forearm and the back of the hand, using the larger space to write, or otherwise interact with the apps on the device.
