Doodlesiris, Feb 4, 2019 : Who are the users? This is for the users who do not have massive hands. The user pain point: While the screen size is a point of pride for many OnePlus users, it also sometimes quite inconvenient to try to reach the top of the screen with one hand. Thumbs are on average only 2.7 inches and it's pretty clear having a 6 inch (or longer) display would lead to some issues. What is the proposed function? The function is to make the screen more accessible when only using one hand. This one handed UI will shrink the screen and shift it to one of the bottom corners. To enable one handed UI, there are a couple options. 1. For phones with fingerprint sensors, you could swipe to the left or right across the sensor. 2. When using the back, home, recents fixed bar, you can simply left or right on the nav bar. 3. When using oneplus' gesture navigation, you can start on the bottom edge and swipe left or right What is the user value? It makes using the phone much more convenient. Users will no longer need to shift the phone in the hands to reach the top corners of the screen while fearing whether they will drop the phone or not. Compared to other one handed gestures The swipe on the nav bar is basically the same as Huawei's one handed gesture, but when combined with oneplus' gesture navigation, it can be very intuitive and smooth. Plus the rounded corners can make it look better than huawei's one handed ui. The additional fingerprint sensor option (for phones with fingerprint sensors) gives users another way to enable one handed UI and makes it much easier. That option is not available on Huawei to my knowledge. Compared to Reachability on the iPhone X, this shrinks the entire screen rather than shift it down, allowing you to see the entire screen. Additionally, the proposed idea moves the edge of the screen to the left or right, not just down which makes it easier to reach the opposite corner of the phone.
