CREAL Reveals Its First Light-field AR & VR Headset Prototypes

While Creal has previously demonstrated its impressive light-field display technology, we’ve only ever seen in it large benchtop demos. Now the company has revealed its latest progress in shrinking the tech to fit into a head-mounted form factor. While its AR and VR prototypes are still fairly large, by 2022, the company says it expects its tech to fit into yet smaller form factors.

Creal says these prototype headsets are ‘evaluation units’ which the company is sending to potential partners to demonstrate its light-field display. The company’s goal is not to build its own headsets, but to supply its light-field display technology to other headset makers.

CREAL AR Light-field Prototype

The Creal AR headset prototype has a resolution of 1,000 × 1,000 across a 60° field of view, according to the company, which also claims ‘unlimited’ depth-resolution (meaning continuous focal planes), with the caveat that it isn’t truly unlimited but that the steps between each focal depth are “much smaller than an eye can resolve.” The Creal AR headset prototype is tethered and uses an Intel RealSense sensor for 6DOF tracking and Ultraleap for hand-tracking. Below you can see a through-the-lens demo showing the ability to focus at different depths.

People Would Shell Out Money For It. Most people recognize that the best virtual reality headsets cost quite a lot. After all, the best virtual reality experience is worth spending money on. One study found that a majority of consumers would be willing to spend up to $500 for the right virtual reality gear. This is really good news, considering that some of the top headsets for virtual reality cost about $500. There are also plenty of lower-priced ones that can be used for virtual reality as well.

While the Creal AR headset prototype is approaching the size of something like HoloLens, the company claims it will be able to fit its light-field tech into a sleek glasses form-factor by late 2022. Doing so will require moving to a foveated version of its display which would see the central 30° of the field of view occupied by the light-field, while the peripheral view would be filled with non-light field imagery out to 60° total, the company says.

Creal is also expecting to reduce power consumption from the current 2W down to 0.5W for the glasses-sized version, while boosting the eye-box to 8mm.

CREAL VR Light-field Prototype

With its VR headset, Creal says it’s already employing the foveated light-field approach, with a 1,000 × 1,000 resolution light-field covering the central 30° of the field of view, and a 1,600 × 1,440 non-light-field view to fill out to 100° total. Because the light-field area is only 30° across, the resulting resolution is 40 PPD, which is approaching the retina resolution threshold (roughly 60 PPD). Below you can see a through-the-lens video showing the headset’s ability to focus at any depth in the scene.

Endless Possibilities with Virtual Reality. Ever wanted to play a tennis match with the likes of Maria Sharapova, or save the world with the Avengers? VR technology has made the impossible possible, thanks to amazing content now available to let users virtually experience stuff they could only dream of. With the help of add-on features or accessories, such as a surround sound audio system or gloves with attached sensors detecting hand movements along with wands and treadmills, VR enthusiasts can enjoy an alternate reality and an entirely different world.

The Creal VR headset prototype is using an Intel RealSense sensor for 6DOF tracking and includes eye-tracking from Pupil Labs, though the company notes that eye-tracking isn’t necessary for the light-field functionality.

As with its AR headset prototype, the bulky VR headset prototype is a step toward a more compact version of the headset which the company expects to have ready by late 2022. By this point the company expects to integrate custom 6DOF and eye-tracking hardware (which would help further reduce the headset’s size).

With the company planning to use a foveated combination of light-field and non-light-field displays going forward, we’ll be especially interested to see how closely the two views manage to blend together.

Creal’s announcement of head-mounted light-field prototypes follows the company’s latest investment round of $7.2 million announced late last year.
