Daydream is a Virtual Reality head-mounted display developed by Google for Daydream Platform. To use Daydream View, users need to mount a Daydream ready Smartphone inside it. The smartphone serves not only as Gear VR's screen but also as its computer. Unlike other mobile HMDs, Gear VR does not solely rely on the smartphone's IMUs for tracking. It has additional IMUs and Oculus' rotational tracking technology built within, allowing for fast and accurate tracking of the user's head movements. While impressive, the current Gear VR does not possess positional tracking.
Announced during Google I/O 2016, Samsung Gear VR was released in November 10, 2016 for $79. Users who pre-order Pixel or Pixel XL will receive the HMD for free.
Daydream Ready Phones
- Google Pixel - Released on October 20, 2016 for $649
- Google Pixel XL - Released on October 20, 2016 for $769
Hardware
Design of HMD
Daydream View consists of a plastic body wrapped in soft fabric. The overall feel of the HMD is simple and light without being cheap. Unlike Gear VR, which has IMUs, fans and microUSB port, Daydream View has only lenses and a NFC tag concealed within the front cover. The HMD does not need to be connected to the phone, the NFC tag detects the phone when it is in place.
The front cover of the HMD is mostly open. It relies on a spring-loaded hinge below, an elastic hook above and few high-friction pads to keep the phone in place. This method allows the HMD to be compatible with phones of various sizes and thicknesses. Additionally, there are 2 black capacity pads that touch the phone's screen. These pads align the VR views with the lenses.
Unlike many other HMD, Daydream View does not have a top strap. It has 1 strap that goes horizontally across your head. It does not use velcro, instead the HMD uses plastic loops to adjust, tighten and loosen the straps.
Problems
Light leak and lens glare are two of the problems with the Daydream View. Because the HMD is designed to accommodate phones of various sizes, light from external environment can enter the HMD from the side of lenses. In scenes of high contrast such as white objects on a black background, you'll see thin layer of light around the edges of your view. Screen door effect is less noticeable on View than on Rift or Vive.
