In 2016, the 10th International iCAN Innovation and Entrepreneurship Competition VR/AR Industry Competition and the first Red Valley Beach Cup VR/AR Innovation and Entrepreneurship Competition Summit was held on September 20th at the Qianhu Guest Hotel in Nanchang. In order to establish a benchmark for the national VR/AR industry, and advance with international virtual reality technology, in the summit forum, please visit a number of industry experts, including Li Weixing, vice president of Qualcomm Technologies Inc., representing the best among chip manufacturers. The guests and the audience brought a very wonderful speech.
Li Weixing said, "Through the development of technology, Qualcomm has connected the vast number of consumers and people directly from the simple mobile phone to the functional machine and the intelligent machine through advanced connection technology in the past 30 years. In the 30 years of walking and going backwards, through our leading position in connection and computing, we believe that not only people are connected, not just through voice, text messages and action data, but in fact, everything can be linked. So the next step may be a very important period in which the Internet of Things is booming."
Li Weixing, Vice President, Qualcomm Technologies Inc.
Qualcomm believes that in the future, the development focus of the VR industry will still be in the mobile industry. There are three main reasons:
First, through the development of smart phones, it provides a synergistic development effect, making the entire smart phone market a scale;
Second, due to various technologies, the rapid development of mobile phones provides a very fast design cycle, so that different ideas can be presented in a very fast way through the mobile phone;
Third, the popularity of the public, the cost reduction, and the popularity of the platform, making it possible for VR and even other mobile terminals to achieve the mobilization of content and consumption, which is quite important. Nowadays, the use and consumption of many contents are still connected to the PC, and the mobilization of content is very important for the consumers.
Of course, the PC control VR mobile terminal is definitely the first step in the development of VR. There are two possibilities for moving backwards. One is a smart phone that brings the VR experience in a cheap and fast way; more importantly, the independent helmet-mounted equipment, because the so-called economies of scale can be presented through independent head-mounted VR equipment.
The development of the VR industry can get different experiences through different devices, but there are two problems that need to be solved together, power consumption and heat dissipation. For the power consumption, how to properly handle the heat, in fact, this is Qualcomm in the development process, invested a lot of power. Moreover, the head-mounted VR devices used by ordinary people are very heavy and very ugly. If you can achieve a very light and stylish design, you need high demands on power consumption and heat dissipation, which is the same as the demand for smartphones. .
For these two issues, Qualcomm believes that the Snapdragon 820 processor is ideal for mobile VR:
First, for visual quality, 4K display is very important. Qualcomm Adreno 530 GPU supports smooth 3D stereo focus rendering, supports the latest GPU API, and can achieve very low power consumption, complete 360 ​​degree 4K HEVC video decoding. And displayed at 60PPS.
The second is sound quality. Qualcomm's AqsTIc audio codec supports positional audio and 3D surround sound, and has specialized techniques for noise filtering and active noise reduction, as well as low-level DSP access and tools for custom audio development.
The third is intuitive interaction. The Snapdragon 820 has powerful computing power, and its integrated Hexgon 680 DSP can also efficiently process vision and audio. Through the combination of dual Spectra ISP and Hexagon DSP, the Opteron 820 can support low-power 3D reconstruction and predict 6DOF motion tracking.
At the same time, the Snapdragon 820 continues to improve in terms of battery life and supports a better immersive experience to achieve improved performance and safe compensation.
In addition, Qualcomm provides developers and vendors with the Snapdragon VR SDK to help them optimize their applications and streamline the development process. Among the important points are: DSP sensor fusion, access to the latest predictive head posture; second, asynchronous time warping, which can be achieved according to the head posture, just before the scan output to complete the distortion image; third is the chromatic aberration correction, according to the lens Features correct color distortion; Fourth, lens distortion correction, barrel distortion according to lens characteristics; fifth is stereo rendering, generating left and right eye images; Seven is VR layering, generating UI menus and texts, while correctly rendering in the virtual world; eight is power and thermal management. Qualcomm provides CPU, GPU and DSP power, cooling and performance management. In the fourth quarter of 2016, Qualcomm will provide the Snapdragon VR820 virtual reality reference platform to help the industry chain accelerate the development of independent head-mounted devices. It is hoped that the entire industry chain will contribute to the entire VR content and games.
Li Weixing said that Qualcomm is looking forward to the future 5G era, and the enhanced mobile broadband service supported by 5G in the future can bring the ultimate immersive VR experience. Qualcomm believes that the VR era has arrived, and VR is actively absorbing all the accumulated technologies and experience in the development of smartphones. Qualcomm's Opteron 820 is perfect for immersive mobile VR. Qualcomm Technology will also have more contributions on VR.
