Headset-Free Augmented Reality

A new projector that superimposes images and animations onto actual objects allows viewers to experience augmented reality (AR) without the need for bulky glasses. Called Lightform, it combines a camera, computer and video projector with a technique called projection mapping to turn any surface into a projection screen.

Using depth sensors, the surface is scanned to map its shape, then the lighting effects are tailored to fit. The control app also periodically rescans the projection area and recalibrates the graphics if anything has moved. The system can be used with existing projectors of any size depending on the application. And since no headset is required, several people can share the AR experience simultaneously.

But there are some drawbacks to not having a headset. For example, there is no haptic feedback or motion tracking to give the illusion of being able to touch and manipulate the environment. It can be difficult to view in bright lighting conditions, and if anything comes between the projector and the projection surface, it will create shadows. But at a price that’s similar to that of a standard laptop, there will undoubtedly be many applications for the immersive technology, from art to entertainment to education to everyday living.
