There are many inevitable bondage in everyday driving, such as the need for mobile phone, car, watching the screen navigation, call, this time will bring many risks to driving high, according to statistics 38% of traffic accidents are caused due to the factors that influence the safety of driving.
TechWeb-sponsored No. 209 in the week IT on forums, see driving technology founder Ma Binbin, also had to communicate with him after the meeting, driving safety and the use of HUD, he had some of his views.
Not simply the pursuit of science and technology
Tesla, in parts of the machine in a 17-inch control display screen, it looked when navigation was actually more impact driving vision. Ma Binbin saying: "Tesla has been to showcase their technologies, but not really from a user perspective. Hand gesture recognition include BMW, will also affect driving. So technology is not equivalent to the products, only the pursuit of science and technology, if technology is not organic and artificial intelligence algorithms, as well as product together, it's just things in the laboratory. "
Ma Binbin deep experience working in gold, according to the statistics, 80% people had missed the crossing because of see map, navigation voice and real road conditions make people hesitate on the one hand, on the other hand about 50 meters of the GPS error under normal conditions, there is no other way to make it easier to deal with these problems?

That's nearly two years closely watched vehicle HUD (head up display). First appeared in the fighter, using optical reflection principle, important flight information onto a piece of glass, and image in the sky. Basic principle is the mirror reflection, if applied to the car, the vehicle HUD information related to navigation through the windshield onto the distance 2-3 meters in front of the car, drivers can focus on the road while you can see the navigation information, contribute to safe driving. And how the glass extends also to road traffic information is precisely in line with eye focus observe road conditions.
HUD display technology analysis
Ma Binbin numerous HUD products one by one the various pros and cons, they eventually choose desktop HUD Navdy instruments, placed on the instrument table, image directly reflect through the front windshield, put them in the machine, than on the rear-view mirror, Sun block vision of a more transparent, minimal impact to observe road conditions.
Ma Binbin tells us that reflection Imaging in the HUD is a AR way, enhance the image to surface, is the most secure. In terms of Imaging is applying the principles of reflection, need to be 40%-60% reflectance coated glass, mirror another refraction only directly through the front windshield, which will have a severe ghosting, if directly reflect the same phone or pad can affect vision, and heat dissipation problems.
Loading HUD is DLP light machine is widely used in the market as the image source, including the driving technology of radish. As HUD hardware core technology, DLP development is relatively mature, number color, dynamic range, resolution is very good, even over LCD in certain areas, such as clarity, color reduction, contrast and so on, but the DLP had a temperature problem, that's why Navdy delays in delivery. Another kind of TFT Panel image, but the bigger the screen costs are very high, the current resolution is the biggest 480*240, existing products are 240*120, but complex maps such as overpass bridge is not legible. By contrast DLP also is the focus of many manufacturers, can improve faster.
BMW, Mercedes, Audi and other carmakers have tried to carry boxes, through internal refraction imaging multiple times in the box 2 metres, relatively large size of the box. If you can reduce costs with antireflection film for reflective coating on one side, but the edge there is ghosting, costs around 5000. If direct front glass, front loading costs will be 10,005. Loading HUD priced between 1000-2000 in the country. Hello Kitty Note 3 cases
Human interactions improve the user experience
In addition to the clarity of the image and product placement from speech recognition interactive human maintained and stability is also very important. In this regard because Chinese language features are more suitable for Chinese speech recognition technology and habits more appropriate dialect and grammar, technical difficulty is learning through data to filter out the noise, SI Chi Ma Binbin has found cooperation in this area. Customized research and development on both sides, in-vehicle speech recognition under the noisy environment, combined with the pavement, speaker characteristics, human-computer interaction to adjust to higher degree of speech recognition. As he says, not too open, set in-car noise environment, they can do better than small, ice, small I.
As Ma Binbin intended future driving recorder, OBD, high-resolution imagery, infrared night vision and so can step in driving a custom ROM system developed, which is an Internet portal. Radishes will open their API so that other manufacturers directly in. Ma Binbin tells us, the second generation of turnips is going to come out, than the first generation, second generation machines will become an open platform as a whole.
HUD also applies specifically to display navigation information or ADAS data, allows the driver to watch the road ahead while other functions. Loading HUD after the home has emerged over more than 10 companies, HUD is already pre-installed on many high-end models abroad.
Challenges not only from the product itself, consumer driving habits also influence their understanding and popularization of the HUD. But in the car market, HUD has gained consumer attention, wanting to make driving safer and livelier, HUD is free driver one of the best early adopters of products.
