User interface control using a keyboard
First Claim
1. A tangible storage medium storing computer-readable instructions that when executed by one or more processors produce actions comprising:
- receiving data comprising a first sequence of key-presses from a first set of adjacent keys on the keyboard and a second sequence of key-presses from a second set of adjacent keys on the keyboard, wherein the first and second set do not intersect;
mapping the sequence of key-presses to a first sequence of coordinates in the user interface and the second sequence of key-presses to a second sequence of coordinates in the user interface;
comparing the first and second sequence of coordinates to detect a multi-touch gesture;
controlling movement of an object displayed in the user interface in accordance with the multi-touch gesture.

Abstract
User interface control using a keyboard is described. In an embodiment, a user interface displayed on a display device is controlled using a computer connected to a keyboard. The keyboard has a plurality of alphanumeric keys that can be used for text entry. The computer receives data comprising a sequence of key-presses from the keyboard, and generates for each key-press a physical location on the keyboard. The relative physical locations of the key-presses are compared to calculate a movement path over the keyboard. The movement path describes the path of a user'"'"'s digit over the keyboard. The movement path is mapped to a sequence of coordinates in the user interface, and the movement of an object displayed in the user interface is controlled in accordance with the sequence of coordinates.
