Crescent Bay is a prototype VR headset from Oculus. Oculus VR revealed it on 20 September 2014 at Oculus Connect, the company's first developer conference, and described it as "the latest prototype headset on the path to the consumer version of the Rift."[1] Compared with the Oculus Rift DK2 developer kit, it added tracking LEDs on the back of the head strap for 360-degree head tracking, a larger positional tracking volume, lower weight and built-in headphones.[1][2]
Crescent Bay was a "feature prototype" rather than a developer kit, and it was not offered for sale.[2][3] Oculus showed it at trade shows in early 2015, including its first public demonstrations at CES 2015.[4] In May 2015 Oculus said that the consumer Oculus Rift "builds on the presence, immersion, and comfort of the Crescent Bay prototype".[5]
Announcement
CEO Brendan Iribe introduced Crescent Bay in his keynote at Oculus Connect in Hollywood, Los Angeles.[6] Oculus said the conference drew nearly 1,000 developers.[1] Iribe compared the jump in quality with the step between the company's first two developer kits: "[Crescent Bay] is as massive a leap as we made from DK1 to DK2."[3] He also said: "This prototype shows the quality, the features, the presence we need to deliver consumer VR."[3]
Oculus listed the prototype's improvements as new display technology, 360-degree head tracking, an expanded positional tracking volume, improved weight and ergonomics, and integrated audio. Its announcement also cautioned that "This is still incredibly early hardware" and that technical problems remained to be solved before a consumer release.[1] TechCrunch reported that Crescent Bay was "not an official developer kit, but instead a 'feature prototype'", in the same way as the earlier Crystal Cove prototype that preceded the DK2, and that it would likely not be shipped to developers.[2]
Other announcements at the same keynote included official Unity 5 support for the Rift and a new research division, Oculus Research, announced by chief scientist Michael Abrash.[6]
Design and hardware
Oculus did not publish a specification sheet for Crescent Bay. Beyond saying that it had a new display with a higher resolution and refresh rate than the DK2, the company gave no display figures.[6][7]
Tracking
Crescent Bay uses the same kind of optical tracking as the DK2: an external camera follows an array of LEDs on the headset. The DK2 had LEDs only on the front, while Crescent Bay adds a panel on the back of the head strap that also carries tracking LEDs, so the camera can follow the headset when the wearer turns fully around.[2] In TechCrunch's Connect demo, the camera was mounted on a wall rather than placed on a desk, and the wearer could walk about 3 feet in any direction.[2] Road to VR's Paul James described standing on a rubber mat "about 5×5 feet" during his demo and reported one tracking hiccup while turning in a full circle over a ten-minute session.[8]
Audio
Crescent Bay added built-in headphones, which Gizmodo described as optional and adjustable in all directions.[3] For the demos, Oculus licensed RealSpace3D audio software, which it said was "a software stack developed over 10 years based on technology from the University of Maryland". It combines head-related transfer function (HRTF) spatialization with reverberation algorithms.[1] Iribe said at the launch: "Starting today, we are working on audio as aggressively as we are on the vision side."[3] Before CES 2015, Oculus revised all of its Crescent Bay demos with 3D audio from its upcoming Oculus Audio SDK, which uses HRTF processing together with the headset's head tracking.[4]
Display and optics
Because Oculus did not disclose the display specifications, reporters could only estimate them. After his first demo, Paul James guessed a resolution of "1440p or possibly higher" and a refresh rate of 90 Hz, saying he could not be certain of either.[8] PCWorld noted rumors of a 1440p panel from the Samsung Galaxy Note 4, which Oculus would not confirm.[7] After trying the headset again at the Game Developers Conference in March 2015, Road to VR's Ben Lang guessed that it used the same 1200x1080 per-eye displays as the HTC Vive, for a combined 2160x1200.[9]
Lang also reported that the headset used Fresnel lenses, with ridges much finer than those on the HTC Vive. He wrote that the black smear visible on the DK2 had nearly been eliminated, and he described a new light-ray artifact in high-contrast scenes (especially white on black), which he suspected came from the Fresnel design. He estimated the field of view as about 10% larger than the DK2's.[9]
Weight and ergonomics
Oculus said Crescent Bay had "dramatically improved weight and ergonomics" compared with earlier hardware.[1] Hands-on reports described it as lighter and more comfortable than the DK2, even with the headphones attached.[3][8] Ben Lang guessed that it was at least 15% lighter than the DK2.[9] The prototype was still tethered by a cable, which PCWorld's Hayden Dingman found distracting when he moved around.[7]
Demonstrations
Oculus built a set of short "Crescent Bay Experiences" to demonstrate presence for games and film. Epic Games created "Showdown", an Unreal Engine 4 demo, for the headset.[1] Press accounts from Connect described scenes including a spaceship interior, an alien on a lunar surface, a miniature papercraft town, a museum corridor with a T. rex, a skyscraper ledge and the slow-motion Showdown sequence.[8][7]

| Game Developers Conference 2015, San Francisco | March 2015 | Debut of "Thief in the Shadows"; Showdown with remixed 360 spatial audio[11] |
At CES 2015 Oculus demonstrated the prototype publicly for the first time, alongside the Samsung Gear VR Innovator Edition. Visitors could book demos through a mobile app or join walk-up lines.[4] TechCrunch's Darrell Etherington reported that the demos included flying debris and bullets, a dinosaur and a skyscraper ledge. In an interview, Iribe told him that Crescent Bay was the first Oculus VR experience that had not left him with lingering nausea, and that it was the first version of the Rift he felt met the minimum standards for a consumer launch, at least in its audio and visual performance.[10]
At GDC 2015, Crescent Bay experiences ran at several booths on the expo floor. "Thief in the Shadows", made by Epic Games, Weta Digital, NVIDIA and Oculus, ran exclusively on Crescent Bay and put the viewer face to face with Smaug, the dragon from The Hobbit. It was built in Unreal Engine 4 and ran on NVIDIA's Titan X graphics card.[11]
Successor
On 6 May 2015 Oculus announced that the consumer Oculus Rift would ship in the first quarter of 2016. According to Oculus, the consumer headset built on Crescent Bay and added an improved tracking system supporting seated and standing experiences, a refined industrial design and updated ergonomics.[5] That headset is covered in the Oculus Rift CV1 article.
