ChrisJeanguenat, Feb 6, 2019 : Who are the users? People with disabilities who can't use their phone with 2 hands, people with small hands that can't type with their phone with one hand. What is the proposed function? 1.When the user twists the phone with one hand twice, depending on if the user twists the phone from left to right (left hand), or from right to left (right hand), the keyboard will shrink and shift to either the left or right to allow the user to type with one hand. 2.The navigation buttons/gestures will be shifted to the right/left of the screen when One Handed Mode is turned on. 3.When One Handed Mode is turned on a track pad and a movable cursor will appear on the screen, the user will then be able to move the cursor around the screen and select items by tapping on the track pad. The user will still be able to tap and hold to select text and hold and drag to select lines of text. The track pad will have a button on the top left/right side that hides it into a non intrusive teardrop style tab that the user will be able to pull out whenever needed. It will also have a button on the lower left/right side of the pad that the user will use to move the track pad up and down to suit their needs. 4. One Handed Mode can be turned on and off via the double twist gesture, in quick settings, and in setting under Buttons and gestures where you can configure the size and color of the cursor, or disable the feature entirely. In quick settings there will be separate options for left and right One Handed Modes. What is the user value? The user will be able to type and navigate Oxygen OS and apps smoothly and comfortably. Any person will be able to quickly activate One Handed Mode and navigate their phone in an uncomplicated way. It will make future OnePlus phones more attractive to people with existing disabilities, and also more attractive in general because it's adding extra functionality to Oxygen OS. If there are existing comparable functions in the smartphone industry, how is your proposed feature superior? Some smartphone manufacturers, such as Motorola, allows the user to shrink the entire screen down to the left/right side leaving big black bars on the top and side. As a previous Motorola user this implementation of one handed use left it hard for me to see the screen due to my thumb blocking a big part of the now smaller screen. I had always felt that there could something that would be a better use of space and didn't detract from the user experience. This feature would set OnePlus apart in the smartphone market and to the consumers as the phone with useful features.
