TDK was exhibiting its newest Good Glasses Outfitted 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 could possibly 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 consumer is taking a look at.
This projection sort doesn’t require the consumer to deal with a close-by floor. The projected picture is obvious 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 data can be offered in a heads-up show model. Throughout 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 photographs are rendered and projected on the retina. TDK developed this use case as a result of basic VR headset that depend on a show pressure your eyes to deal with 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 totally different focus level. That might additionally trigger cognitive pressure.
Within the direct-to-retina projection, the eyes don’t must deal with a selected show floor, and the consumer is free to let the attention’s focus wander wherever the 3D picture suggests, which might remove one supply of VR illness.
There are different theoretical methods to repair the eye-focus pressure, reminiscent of utilizing lightfields. Nevertheless, that approach vastly will increase the 3D-rendering load. TDK’s retina projection doesn’t induce such a problem. Nevertheless, retina projection requires a really exact projection and could be much less forgiving when customers transfer their eyes away from the projector.
