On March 23rd, OPPO Guangdong Mobile Communication Co., Ltd. announced the patent of "Metro Reminder Graphical User Interface with Display Panel", WeChat official account CN306402577S. According to the patent abstract, the appearance is used to display subway information on the graphical user interfaces of mobile phones and tablets, and to remind users who take the subway. At the same time, click the prompt box at the bottom to see the details.
Being able to remind us of our arrival at the station in real time with a mobile phone will undoubtedly bring us a lot of convenience, so that we will not miss the station because of unexpected situations such as distraction. After all, for many people, distraction is often because we are too focused on watching mobile phones. Being able to locate our position in the subway in real time requires not only the display of the software interface, but also the positioning accuracy and signal of the mobile phone. I believe OPPO may also make a breakthrough in this respect.
In addition, careful observation of the abstract in the patent application shows that OPPO can even remind us that we may have taken the subway in the opposite direction, which undoubtedly puts a severe test on the positioning accuracy of mobile phones. On the one hand, it may be judged by the mobile position of the mobile phone, on the other hand, it may be judged by the direction in which we enter the subway train. In either case, I believe that the judgment of positioning accuracy should be below 1 meter. If it is in an outdoor environment with good signal, it is still relatively easy to achieve. However, in the relatively closed environment of the subway with poor signal, I don't know whether OPPO will cooperate with operators to break through the limit of mobile phone positioning accuracy again.
As far as the patent of graphical user interface exposed at present is concerned, it will not only bring us a solution to the pain point problem, but also have a deeper innovation in mobile phone positioning technology. If OPPO can realize this function in the near future, I believe it will bring us another innovation in the positioning accuracy of mobile phones. This is believed to be a great progress for our daily use of mobile phones for high-precision navigation. After all, OPPO has already launched a technical demonstration of AR real-life navigation before. Looking forward to OPPO's continuous technology research and development, it will really bring revolutionary technology experience to our consumers. We might as well wait and see.
