Whereas Cardboard was used by running compatible apps and was accessible on most smartphones, Daydream was built into the Android OS itself and only worked on select phones that met the platform's standards, such as having specific hardware components. In January 2017, Google opened the Daydream program for all third-party developers. Software Īndroid Nougat introduced VR Mode, a low- latency, "sustained performance mode" to optimize the VR experience for Daydream. It dedicated a CPU core to the user interface thread to reduce visual issues that could induce nausea. Whereas the GPU normally sends frames to the device display in a " double buffering" mode on Android, VR Mode switched to "single buffering" to avoid intermediate frame buffer and instead draw frames directly to the display. The mode also allowed for asynchronous reprojection, whereby frames were slightly transformed to account for positional changes in the user's head that occurred during the 16 milliseconds that each frame was rendered and sent to the display. VR Mode also performance tuned the motion sensor pathways to result in quicker input from the device's accelerometer and gyroscope. The mode assisted developers in optimizing apps to a device's thermal profile. Overall, the performance improvements of VR Mode resulted in motion-to-photon latency decreasing on the Nexus 6P phone from 100 milliseconds on Android Marshmallow to less than 20 milliseconds on Android Nougat. ĭaydream also included a new head tracking algorithm that combined the input from various device sensors, as well as integration of system notifications into the VR user interface. ĭaydream allows users to interact with VR-enabled apps, including YouTube, Google Maps Street View, Google Play Movies & TV, and Google Photos in an immersive view. Google recruited media companies like Netflix and Ubisoft for entertainment apps. ![]() The first-generation Daydream View headset, closed (top) and opened with the controller visible (bottom) The first-generation Google Daydream View was announced on October 4, 2016.
