  • Gesture-based screen-magnified touchscreen navigation
    Patent number: 8869062
    Abstract: Screen magnification software on a touchscreen device detects when a low-vision user reaches the boundary of a magnified viewport. If additional canvas or menus lay on the other side of the boundary the present invention enables the low-vision user to maintain the same exploration gesture on the touchscreen while causing the underlying canvas to scroll into view in the direction of the gesture. This invention enables the low-vision user to navigate about the entire underlying canvas of a touchscreen graphic user interface with a single, intuitive touchscreen gesture even under magnification.
