LuminAR

LuminAR reinvents the traditional incandescent bulb and desk lamp, evolving them into a new category of robotic, digital information devices. The LuminAR Bulb combines a Pico-projector, camera, and wireless computer in a compact form factor.

This self-contained system enables users with just-in-time projected information and a gestural user interface, and it can be screwed into standard light fixtures everywhere. The LuminAR Lamp is an articulated robotic arm, designed to interface with the LuminAR Bulb. Both LuminAR form factors dynamically augment their environments with media and information, while seamlessly connecting with laptops, mobile phones, and other electronic devices. LuminAR transforms surfaces and objects into interactive spaces that blend digital media and information with the physical space. The project radically rethinks the design of traditional lighting objects, and explores how we can endow them with novel augmented-reality interfaces.

This project of a MIT Student named Natan Linder, is a sentient desk lamp that has little hope of replacing your desktop lamp any soon but it certainly is considered to be an offer in the near future because of the heavy endorsement and support from big time companies like Intel and Microvision.
It uses a Microvision Show WX projector, which is both focus and care free. Yet it is under research but this release is definitely a preview of what might be how a personal computer or part of its applications might look like in the next decade.
