Using a portable projector combined with an RFID reader, researchers at Mitsubishi Electric Research Labs have invented a way to project labels directly onto objects identified by RFID tags.
This is more than a new user interface, it also includes a completely new idea for tag singulation.
To find an object, a user aims a radio frequency reader in the general direction of a collection of tagged objects. Each tag that is in range is activated by the radio frequency signal, prompting its photosensor to take a reading of the existing light. Once this is done, the projector embedded in the reader turns on, and each tag that detects an increase in illumination sends a response indicating that it is in the projector beam and is ready for interaction.Imagine using a single device to interact with mobile robots on a large construction project, directing them like a conductor directs a symphony. Then again, this is just what I need for an all-in-one remote control for my Evil Villain’s Lair.
What uses can you think of for this technology?
