I Have Examined TDK’s Direct Retinal Projection System

TDK was displaying its newest Smart Glasses Equipped with a Full-color Laser Module throughout CEATEC 2023, and I had a chance to check it at their sales space. The corporate has been engaged on this expertise for a number of years, and issues are shifting alongside two axes.

First, it’s attainable to have a head-mounted show expertise. Secondly, the identical expertise might be utilized in XR headsets. The expertise depends on projecting a picture instantly onto the retina as a substitute of onto a show floor the person is .

This projection kind doesn’t require the person to give attention to a close-by floor. The projected picture is evident and sharp whether or not you have a look at one thing close to or far, which might be a bonus for AR functions, the place info can be introduced in a heads-up show type. In the course of the demo, some textual content was projected instantly onto my retina (720p decision), and it remained sharp as I checked out issues near me or distant. At this level, that is essentially the most advantageous use of this expertise.

Subsequent, there was a VR-style demo, which TDK describes because the “World’s first VR goggles with direct retinal rendering.” Every eye has a projector, and naturally, two photos are rendered and projected on the retina. TDK developed this use case as a result of traditional VR headset that depend on a show drive your eyes to give attention to the close-by show to see a pointy picture. That is inflicting some muscular-level eye pressure, however concurrently, the 3D picture that’s proven suggests a completely completely different focus level. That might additionally trigger cognitive pressure.

Within the direct-to-retina projection, the eyes don’t have to give attention to a particular show floor, and the person is free to let the attention’s focus wander wherever the 3D picture suggests, which might eradicate one supply of VR illness.

There are different theoretical methods to repair the eye-focus pressure, comparable to utilizing lightfields. Nonetheless, that approach vastly will increase the 3D-rendering load. TDK’s retina projection doesn’t induce such a problem. Nonetheless, retina projection requires a really exact projection and is perhaps much less forgiving when customers transfer their eyes away from the projector.
