The development of science and technology is often the process in which one new concept is constantly being proposed, denied, reconfirmed, and subsequently popularized. Looking back at history, the smart phones, touch screens, and mobile Internet that we have long been used to have experienced this kind of experience, and the current phenomenal VR industry is constantly looking for a breakthrough that is closer to users. In fact, what is the most important factor if someone asks about the experience of a VR device? I think the most appropriate answer is immersion. Compared with traditional equipment, the immersive sensation created by VR equipment stimulates the user's senses and provides us with a more realistic experience outside the real world.
But do you know something? What exactly is an immersive experience?
It’s not enough to interfere with the trinity, it’s the essence of the immersive experience.
200,000 years ago, the ancestors of humanity learned to walk upright and walked around the world with their feet. Since then, the human world has been eating and drinking more than a whole day. The establishment of the order, the birth of the text, and the change of the country have made us dangerous. The plain rainforest moved to the signified city, and finally the development of the Internet and even the mobile Internet is that we can talk to the world on a screen of one acre.
Whether it is a dialogue with a dangerous wilderness, a negotiation with a city sign, or a touch between screens, it is a form of interactive experience. Over the past 20 years, UI designers have put the model of space abstractly on the 2D plane of the screen, thus creating a digital world in which we can clearly manage and control. In fact, in the current complex information, UI interaction The pros and cons determine whether we can quickly understand and understand the content and handle the task.
Therefore, before the VR device really arrives, the immersive experience spreads as a simple and clear form of interaction. Its biggest feature is less interference, users can focus more on the task or the content itself, and the designer is interested in design. In the UI, you can improve the immersion by reducing the number of elements, reducing the visibility of irrelevant elements, hiding elements, and even reducing the difficulty of interaction.
In fact, this coincides with the immersive experience emphasized in the VR field, but when you need to break the boundaries of the screen and create a “real†world for users, there are no doubt more factors for VR to consider. What we see, hear, and feel in the real world requires realistic simulations. So, to sum up, VR devices need to achieve at least an immersive experience:
Higher visual quality with realistic sound quality intuitive interaction
Only with these three excellent experiences can you feel more immersive.
Qualcomm Snapdragon 835 is ready
Many people may not know that in the Qualcomm Snapdragon 820 period, providing immersive experience is already the best of the Snapdragon processor, and in the Qualcomm Snapdragon 835 mobile platform, Qualcomm has also prepared for a more realistic world. Combined with the Adreno 540 GPU, Hexagon 682 DSP and Qualcomm AqsTIc audio, the Qualcomm Snapdragon 835 is already geared towards an immersive experience.
The first is the visual experience that users are most concerned about. In Qualcomm Snapdragon 820, Qualcomm first divided Adreno into three parts: GPU, VPU and DPU. The former is prepared for high-performance graphics calculation, while the VPU and DPU are displayed with Display Processing. Processing) and MulTImedia Processing (multimedia processing) as a naming, they provide a more accurate picture display and better video playback performance.
In the Qualcomm Snapdragon 835, the DPU and VPU are also designed. Compared with the 60FPS 4K HEVC video playback capability of the Snapdragon 820, the Qualcomm Snapdragon 835 processor also adds 10-bit wide color gamut support for the first time. The device has common picture jitter and frame drop problems. The DPU also has Q-Sync picture jitter compensation technology, which makes the display picture more stable, so as to obtain accurate picture display. It is worth mentioning that while users enjoy ultra-high-definition video, they can stream content to the 4K display, and can also reduce the wireless stream power consumption by compressing the transmission bandwidth through UBWC technology.
As one of the highlights, Qualcomm Snapdragon 835 also provides support for the HDR10 standard at the chip level for the first time, which means that OEMs can easily use the Qualcomm Snapdragon 835 VR platform to create more HDR-rich head-mounted devices.
At the same time, the new Hexagon 682 DSP can also provide accurate sensor data for the Adreno 540 GPU. The combination of the two enables VR to achieve better sound, image and 3D rendering, combined with a three-axis gyroscope, three-axis accelerometer And the dual camera capture mode provides 6DoF (six degrees of freedom) motion capture technology, which makes VR enough to get rid of heavy locators and cables, and can accurately sense user operations in the case of only one head display device, which means Get an intuitive interactive experience in any space, and this is an important part of an immersive experience.
In the audio section, you have to mention Qualcomm AqsTIc. Many people think that audio is limited to music playback. However, for VR devices, it is often necessary to obtain accurate voice commands in a noisy environment. At this time, the Fluence noise reduction technology in Qualcomm Snapdragon 835 is enough to help. Busy, it can use multiple microphones for echo noise reduction. The AqsTIc audio codec integrates a digital-to-analog converter (DAC) that supports 24-bit 192kHz audio, while Aqstic also supports Hi-Fi-level DSD formats, as well as SNR and THD+N.
The above three aspects are not all of Qualcomm's immersive experience. In fact, the X16 LTE modem equipped with Qualcomm Snapdragon 835 is also VR-enabled. It supports 2*2 MIMO and has a maximum of 1 Gbps downlink, which means unimaginable in the past. The 4K ultra-clear stream and wireless 3D game display has changed from imaginary to reality, and the existing VR “post-brain intubation†is finally going to be history. Imagine, perhaps the 2018 PyeongChang Winter Olympics Qualcomm and related OEMs will bring some new ways to play, you no longer have to sit in front of the TV to watch the game, but wear a VR helmet, real-time streaming 4K Ultra HD live.
Therefore, in terms of audio, image and intuitive interaction, Qualcomm Snapdragon 835 has come up with a complete solution, which helps OEMs reduce the development cost of VR products and shorten the development cycle. For the consumer, buy a high-quality immersive VR at a lower price, bring it to experience another life experience, the complex calculations behind it are all handled by the little Snapdragon 835, this kind of The days are not far from us.
