- A new Huawei patent details a new control method for rollable phones.
- The company described how to use air gestures to retract or expand the display and control the speed of this process.
- The patent is based on the company’s previous rollable phone documents.
The rollable phone provides the convenience of a tablet in the form of a traditional smart phone. But the way and time to control the expansion of the screen seems to be the next development battlefield. Huawei has now developed a solution powered by gesture sensing intelligence.
First, Huawei can allow users to control the screen expansion by sliding with a physical finger, and provide tactile feedback and audio alerts. However, the company also detailed an aerial gesture control method. Users can activate the screen by sliding their hands over the camera or dedicated sensor. The sensor then converts this movement into a retracted or expanded display. It is worth noting that Huawei’s gesture system can also allow users to slow down or speed up screen scrolling. This can be done by keeping a certain number of fingers above the sensor.
Huawei has tried gesture control on its Mate series before. It was developed for users who intend to use the device hands-free, but it may be more useful on larger devices, such as rollable smartphones. In some cases, activating the display with free gestures may be smoother than using two hands on the device.

This is by no means the first rollable mobile phone patent we have seen from Huawei. The previous document described a cell phone with a wrap-around display, while the other group described the drive system of the display in detail.
It is not clear if or when Huawei will launch a rollable phone. If patent streaming is feasible, it is by no means a dead project.
