It’s been a while since I’ve covered anything in the VR and AR markets, so here’s a very quick catch-up on the main products I have been following on-and-off in these pages, and about which I’d been meaning to write about during October / November.
Oculus Rift: Touch and AWS
In October 2016, Oculus Rift opened the doors to pre-orders of the Touch, their hand controller system, due to start shipping on December 6th, 2016. The Touch price point is US $199.00 (approx. £189 / €187 / AU $265), which includes of Toybox, the multiplayer sandbox application designed specifically to show-off the controllers, and five Touch-ready game tiles.
Alongside of the Touch, Oculus announced additional Rift sensors would also be shipping on December 6th, 2016, at a price of US $79 (approx. £62.55 / €74.18 / AU $106.47), offering similar room-sized scanning capability as the HTC Vive. A new earbud system, designed to replace the earphones on the headset for a more immersive sound experience, was also made available for pre-order (again shipping on December 6th, at a cost of $49 (approx. £38.81 / €46 / AU $66).
As a rough-and-ready price comparison. The HTC Vive, which includes a headset with front-mounted “see-through” camera, two controllers and two room sensors for tracking) is prices at about US $800. The Oculus Rift (which ships with one sensor) + touch + and additional sensor comes to roughly US $877, with some recommending two additional sensors offer optimal scanning bringing that total to US $956. Obviously, the latter package also includes a hefty amount of additional software, including Toybox.
On November 10th 2016, Oculus VR confirmed they were lowering the minimum specification for hardware needed to run an Oculus VR experience comfortably, as a result of something called Asynchronous Spacewarp, or AWS. The announcement came with a long and involved description of what AWS is, which the press announcement summarised down to a TL;DR summary:
Oculus is releasing a new technology aimed at reducing system hardware requirements while maintaining content quality across a wider array of hardware. Asynchronous Spacewarp (ASW) is a frame-rate smoothing technique that almost halves the CPU/GPU time required to produce nearly the same output from the same content. Like Asynchronous Timewarp (ATW), ASW is automatic and enabled without any additional effort from developers.
In other words, and to summarise the summary, AWS allows VR experiences remain fluid to the eye by “making up” the “in-between” animation frames, reducing the demand of continued, heavy processing on the part of the CPU / GPU.
This is turn means that “lower end” systems can now in theory run VR experiences which incorporate AWS. Although it has to be said that “lower end” must be approached with something of a caveat: it reduces the GPU requirement from a minimum of a NVIDIA GTX 970 / AMD Radeon R9 290 and Intel i5-4590 equivalent or greater to a NVIDIA GTX 960 / AMD Radeon RX 470 or greater and Intel i3-6100 / AMD FX4350 or greater – which some might consider a small move of the needle.
Finally, Oculus VR is working on an untethered version of the Rift headset, currently called Santa Cruz. It appeared in prototype form in October 2016, and includes a built-in processing system mounted with the headset, removing the need for it to be connected to a PC. Initial reports from those able to try the prototype were mixed, with several reporters noting their evaluations were carefully controlled, and that Oculus engineers were evasive when asked about the actual processing power and performance of the headset.
On November 11th, 2016, HTC announced pre-orders were open for a “tether-less” kit for the Vive headset, produced by TPCAST, a Vive X Accelerator invested company. The kit comprises a wireless relay unit and battery pack to power the headset, bot of which attach to the headset harness, removing the need to connect it to a PC via USB cables. In difference to claims that wireless is “unsuitable” for VR due to factors such as latency, TPCAST is said to have no “noticeable difference” when using it with a Vive headset when compared to using the headset tethered directly to a PC.
