Valve Patent Application Revealed For A Wireless VR System

Avatar

Published

on

A new patent application filed by Valve last year but published today details a wireless VR system.

“In at least some implementations, a wireless data transport system is provided that includes an electrically steerable antenna, such as a phased-array antenna, that is operative to selectively steer its beam based on electronic control input,” the patent application’s description reads.

“The wireless data transport system may include a tracking subsystem that is operative to track a mobile wireless device (e.g., HMD, tablet computer, smart phone) as the mobile wireless device moves around in a tracked volume. Advantageously, the wireless data transport system utilizes the known current or predicted future position and/or orientation of the mobile wireless device receiving the data (e.g., video data) from the tracking subsystem and compensates for movement of the mobile wireless device by selectively adjusting the beamforming pattern of the steerable antenna based at least in part on the tracking data received from the tracking subsystem.”

We confirmed recently that Valve continues to explore wireless VR possibilities but this patent application offers one of the most interesting looks yet into the ideas being explored by the maker of the Index headset and SteamVR Tracking system.

“Among other things, this feature allows the amount of buffering to be decreased, which decreases latency—a critical parameter in some applications such as VR applications where MTP is an important industry metric,” the application continues.

“Further, in at least some implementations, tracking data from other objects, such as one or more hand-held controllers, may also be used to detect when a user’s hands are moving in a direction that may occlude the receiver antenna of the mobile wireless device. It has been found that even partial occlusion by a user’s hand, for example, can cause significant data loss without relying heavily on buffering, interleaving, or forward error correction.”

Earlier in the month a behind-the-scenes look at the making of Half-Life: Alyx confirmed that Valve’s hardware team is working on “what’s next”. The company’s Jeremy Selan himself noted the Index was already “two years old technology” at this point. In our interview following Alyx’s launch, Valve’s Greg Coomber also suggested that the game’s ending could have some implications for the future of the company’s hardware.

We’re still digging into the patent application and will update this post as we dissect more information about it.

Unity announces plans to release experimental version of Unity OpenXR early next year

In Augmented Reality, Virtual Reality and Mixed Reality News

October 24, 2020 – Unity Technologies, a leading platform for creating and operating interactive, real-time 3D content, has recently announced that it plans to have early previews of its support of OpenXR on some platforms as early as the end of this year (Unity 2020 release cycle). The company noted that it has been closely monitoring the development of the OpenXR standard, and has accelerated its efforts to enable OpenXR in Unity.

OpenXR is an open standard created by the Khronos Group, aimed at simplifying augmented and virtual reality (AR/VR) development by allowing developers to seamlessly target a wide range of AR/VR devices. Unity is a member of the Khronos Group and is an active contributor to the OpenXR standard.

In a blog post on the announcement, Matt Fuad, Sr. Technical Product Manager, AR/VR at Unity, commented: “We’re at an inflection point now, where OpenXR 1.0 has been ratified and OpenXR runtimes by various vendors are reaching maturity. This inflection point has accelerated our efforts to enable OpenXR in Unity. Though we’re still working through some details, we want to reiterate our commitment to OpenXR and are excited to share our latest plans.” 

As OpenXR becomes the primary backend for many platforms, Unity added that it is working with its partners to ensure full Unity support of their OpenXR runtimes, along with the necessary OpenXR extensions to ensure parity with existing features. The company stated that its development efforts and support will be focused on providing the best developer experience on Unity supported platforms.

Furthermore, by enabling OpenXR support on partner platforms, it affords Unity the ability to make support widely available for other OpenXR runtimes/devices. Early next year, the company plans to release an experimental version of Unity OpenXR that works with other conformant OpenXR runtimes based on the OpenXR 1.0 specification. Of course, the company clarified that given the unbounded combinations of possible hardware/software configurations, it will not be able to test or guarantee that all configurations will work optimally. However, as issues are discovered with runtimes, Unity stated that it will work to contribute conformance tests and specification changes back to the Khronos working group to help the community as a whole. Additionally, the company will also make sure that it is clear to developers which platforms have been fully tested and thus supported by Unity.

Fuad added: “Our mission is to make it as easy as possible for developers to take their content to the widest set of desired platforms. OpenXR is an important part of that story, and will be implemented as a part of our XR plug-in framework (XR SDK).”

This means developers will be able to continue using Unity’s suite of XR workflows and frameworks (AR Foundation, XR Interaction Toolkit, Unity MARS) for platforms that adopt OpenXR, as well as platforms that may choose not to adopt it.

Unity noted that it will be announcing more updates over the coming months. For more information on OpenXR, please visit the Khronos Group’s website.

Competition: Win Either Angry Birds VR or Acron: Attack of the Squirrels! for Oculus Quest

Avatar

It’s coming up to the season of giving and what better way to start the celebrations early than with a competition where you can win some videogames. Today’s giveaway is a double bill, with Resolution Games’ Angry Birds VR: Isle of Pigs and Acron: Attack of the Squirrels! up for grabs.

Angry Birds VR

Rovio’s iconic Angry Birds franchise came to VR in 2019 with a selection of core levels which have been expanded upon over time. One of the major updates to the bird flinging experience was the addition of a level builder late last year, followed by online sharing to massively enhance the gameplay possibilities.

Acron: Attack of the Squirrels! on the other hand, is a purely multiplayer experience. One person is in VR controlling a tree trying to protect its golden acorns from a bunch of thieving squirrels. All the squirrels are controlled by players on mobile devices – via a free app – who are able to select characters with particular traits such as burrowing short distances underground. All making for a fast and entertaining party game.

Most recently, Resolution Games released a Halloween update for both titles, adding new levels as well as spooky themes to get into the spirit of the season as a lot of developers like to do.

Acron: Attack of the Squirrels

So onto the competition. VRFocus has got six codes to give away, three for Angry Birds VR: Isle of Pigs and three for Acron: Attack of the Squirrels, both for the Oculus Quest platform. There are multiple ways to enter the giveaway with the standard prize draw entry rules applying: Follow us (or already be following us) on Twitter or alternatively, visit our Facebook page or YouTube channel to get an entry for each. Winners will receive a single randomly drawn code. The competition will be open until 11.59 pm GMT on Monday 26th October 2020. The draw will be made shortly thereafter.

Earlier assignments from Forms+Surfaces have included an AR-enabled iOS app. In addition, Sayduck states that it has created multiple products as simpler, non-configurable items in the past.

Commenting on the agreement, Niklas Slotte, Managing Director at Sayduck, said: “I am very happy that we have gained continued trust from one of our oldest customers. We have had a strong collaboration for more than seven years and with this agreement we will develop our partnership even further.”

Bublar added that Sayduck’s strategy is to help product manufacturers and e-commerce companies to showcase and present their products in more immersive ways. The Sayduck Platform allows companies to create unique web 3D and AR experiences for their customers, helping to drive product engagement and customer confidence.
