On Building A Programmable Wireless High-Quality Virtual Reality System Using Commodity Hardware
PROCEEDINGS OF THE 8TH ASIA-PACIFIC WORKSHOP ON SYSTEMS (APSYS '17)(2017)
摘要
All existing high-quality virtual reality (VR) systems (e.g., HTC Vive and Oculus Rift) are tethered, requiring an HDMI cable to connect the head mounted display (HMD) to a PC for rendering rich graphic contents. Such a tethered design not only limits user mobility but also imposes hazards to users. To get rid of the cable, "cable replacement" solutions have been proposed but without any programmability at the HMD side. In this paper, we explore how to build a programmable wireless high-quality VR system using commodity hardware. With programmability at both the PC side and the HMD side, our system provides extensibility and flexibility for exploring various new ideas and software-based techniques in high-quality VR. We present our system design, describe challenges, explore possible solutions to cut the wire, and compare the performance of different approaches for transmitting the high-volume graphics data over a wireless link. We share our experience and report preliminary findings. Experimental results show that building a wireless high-quality VR system is very challenging, and needs extensive effort on both the software and hardware sides in order to meet the performance requirements.
