One of the fashions in terms of design that we have liked the most in recent years has been the inclusion of the fingerprint reader in the back . This is still an essential requirement to achieve a higher percentage of screen on the front of the device, since it is necessary to reduce the frames to the minimum. On the other hand, the fingerprint reader of the most recent terminals is just where our index finger rests when we pick up the phone , finger that, next to the thumb, is the one that most people have configured to unlock their terminal. The fingerprint reader has finally found his place . Now it’s time to take advantage of it.
After all, the fingerprint reader does not stop being that, a fingerprint reader , whose function is to protect our device from the eyes of others – or, rather, the hands of others. Beyond that, the utility of the fingerprint sensor is minimal. Why not take advantage of it a little more by implementing gesture navigation? That way, by placing your finger on the fingerprint reader we could interact with the screen interface to, for example, scroll through a web page, browse a WhatsApp chat, display the notification curtain, and even open the application drawer.
Basically, this new function would be like turning the fingerprint sensor into a touchpad similar to that of laptops.
What I say is not something new. In fact, the Motorola Atrix 4G, released in 2012, allowed to do something similar , in the same way that Google Pixel and some Samsung and Huawei smartphones allow it. The idea is that Google implements this gestural navigation natively in all Android and, of course, can be customized. It is true that there are already apps like(developed within XDA) that allow this, but there is nothing better than functions implemented natively to guarantee optimal operation.
Gestural navigation in the fingerprint sensor, in addition, takes on all the sense of the world seen the latest advances in screens , which tend to be increasingly elongated. If you have one of these long phones with panels 18: 9 or 19: 9 You will know that reaching with one hand at the top of the screen to download notifications is complicated, why not allow this to be done naturally by sliding down on the fingerprint sensor? Why not allow scrolling in Chrome by sliding up and down? It is a very simple gesture that could improve user interaction with your smartphone. What do you think?
