On June 29, Huawei has published a new patent for QR code processing method and device with announcement number CN113051542A in China. According to the information, this patent was applied for registration on December 26, 2019.
QR code stands for Quick Response code and type of a matrix barcode (two-dimensional bar code). Additionally, QR codes often contain data of the user, identifier, locator, and more.
As of now, the QR codes system becomes popular because of its cheap, fast readability, and informative identification method. Now, it also becomes an essential part of life in some scenarios.
Moreover, sometimes these QR codes may be attacked by malware, and they were very harmful to users. When the electronic device generates a QR code and after the malware attack it displays the QR code generated by malware instead of the initial one. This can surely cause damage to the user’s property.
To overcome this situation, Huawei innovates a new QR code processing method and device and published it in the form of a patent.
This patent document describes the QR code processing method and the device, where the method includes: The first electronic device and the second electronic device.
The first device obtains the QR code displayed by the second device and information according to the QR code information, to determine the QR code data and the second scene information.
Whereas the second information is associated with the second device, when the first device determines that the first and second scene information meets the preset condition. Then, the first scene information is scene information related to the first electronic device.
By comparing the scene information of two electronic devices that need to interact with the QR code. Then, to verifying the QR code, you can effectively ensure that the QR code scanned is not a QR code that has been maliciously attacked to ensure the reliability of the QR code.
Huawei to bring new VR head mounted technology: Patent
Huawei is working on new a new VR technology, it’ll add more advanced devices to the company’s collection. In this line, the company has released a new patent, which recently gets the approval of the Chinese Intellectual Property Database. It’ll be a lightweight VR head unit and will release the pressure while wearing the device.
As per the information, Huawei applied for a patent entitled “a head-mounted display and virtual reality system” back in March 2019. Now, it has passed the examination phase and the company has published it with the publication number CN111694152B in China on 14 September 2021.
The patent abstract shows, the described head-mounted display will make the users interact with virtual reality. Furthermore, during the time wearing the head unit users won’t feel much pressure and can enjoy the work with more comfort.
Huawei VR Technology Patent Description:
The application describes that the device will have a main head unit module, two magnetic arrangements, and integrated technologies. Furthermore, the first magnet won’t be dependent on the head unit body. Meanwhile, the second magnet structure will be used for opposite forces.
Thus, this magnetic arrangement will provide the head modules a skyward magnetic force. The technology will be in the virtual reality applications that will provide less pressure.
In June 2021 Huawei Headheld and HeadPositioner (VR) have passed Bluetooth SIG certification with model numbers Par-CG013 and Par-CG012 respectively. Both models will work on Bluetooth 5.0. However, the company hasn’t revealed any further information yet.
Huawei Rollable phone meets Gestures navigation, Nice
In the past, we’ve seen a number of new Huawei patents and designs about rollable phones. Compared to the foldable design, the rollable phone extends outwards from within a regular phone size.
However, new patents continue to appear. In the latest edition, LetsGoDigital has found a new rollable phone design that was filed in February 2020 at World Intellectual Property Organization (WIPO). The patent is titled ‘An apparatus and a method for a controllable foldable display with haptic and sound effect’. The 38-page documentation was approved and released on September 2, 2021.
Huawei Rollable Phone with Gestures:
Aside from its design, the new patent has new hand gestures called Freehand Gesture Control. To conduct such controls, a virtual slider is shown on the screen.
The extended display will be accompanied by haptic feedback (screen vibration) and a sound effect. The advantage of this display extension sound compensates for the noise generated during the rolling process.
Not only that, there are plenty of hand movements that users can make to enjoy a seamless gestures movement across this futuristic device. These includes:
- Swipe above to roll in or out
- A movement to the right to unroll or left to retract

Manage Roll Speed:
The gestures are so advanced, they could even allow users to manage the speed of the rollout and roll back-in process detected by the use of the finger count and is detected by a motion sensor or a camera module. This is quite interesting and is surely futuristic to see that happen.
Realistic Concept Video:
Huawei Mate Rollable appears to be a normal smartphone at first sight. But it has the ability to expand into tablet-like big screen size. Unlike the foldable, the rollable smartphone can increase or decrease the area of its display by rolling in and out.
The phone’s front design looks identical to any regular smartphone, yet it can expand to a large tablet at an instance. Unlike a foldable device, the Rollable phone can expand outwards by taking a limited space. Through this mechanism, a 6.5-inch panel can expand to an 11-inch screen.

Huawei publishes multi-screen interactive patent for smart cars
Huawei has shared a new patent multi-screen interactive technology for smart cars. It was applied back on the 26th of April this year and has published with the publication number CN113330395A in China.
The patent entitled “a method, device, terminal equipment, and vehicle for multi-screen interaction” revolves around smart car technology. The method described in the patent uses a high-definition camera and specific gestures to derive multi-screen interaction.
As per the described approach, at first, the camera analyses a pre-defined specific gesture and captures the command. Afterward, the carried content represents on the first display screen in sub-images alongside other sub-images on the screen.
With this projection on the first screen and derived information, the users can easily presume the movement direction of subsequent gestures. After that, the same procedure is followed for the second screen and controls the sub-images presenting on the first display screen.
Thus, the display screen moves according to the gestures. But when the distance between the gestures and system reaches out of range, the sub-images shift on the second display screen and carries out the multi-screen interactive function.
Last week, Huawei published a vehicle braking patent that contains a power recovery control method according to the state of charge of the battery. It’ll help in taking a more precise decision regarding turning on/off the battery recovery so the users won’t have to face a sudden battery back out.
