Abstract
An input method based upon a multi-touch screen and for use in an electronic device is disclosed. Firstly, a lookup table is stored. The lookup table includes commands and groups of inputs, where each command is associated with a group of inputs. Two touch signals of two inputs are detected. If the two touch signals are detected at the same time, corresponding locations of the two inputs are detected too. Otherwise, the two touch signals are cleared. A group of inputs are determined based upon the two touch signals and the two touch locations. Then, a command is looked up using the determined group of inputs and the lookup table. Finally, the command is inputted to the electronic device.

A touch-screen based input method for use in an electronic device, comprising:
- storing a lookup table, the lookup table comprising a collection of commands and a collection of groups of inputs, where each command is associated with a group of inputs;
- detecting a first touch signal of a first input on a multi-touch screen;
- detecting a second touch signal of a second input;
- determining whether the second touch signal is detected during the detecting of the first touch signal;
- detecting a first touch location of the first input and a second touch location of the second input if the second touch signal is detected during the detecting of the first touch signal;
- determining a group of inputs according to the first touch signal, the second touch signal and relationship between the first touch location and the second touch location;
- indexing a command corresponding to the determined group of inputs using the lookup table;
- and
- inputting the indexed command to the electronic device.
A touch-screen based input system for use in an electronic device, comprising:
- a storing unit configured for storing a lookup table, the lookup table comprising a collection of commands and a collection of groups of inputs, where each command is associated with a group of inputs;
- a first detecting unit configured for detecting a first touch signal and a first touch location of a first input on a multi-touch screen;
- a second detecting unit configured for detecting a second touch signal and a second touch location of a second input on the multi-touch screen;
- a determining unit configured for determining a group of inputs according to the first touch signal, the second touch signal, and relationship between the first touch location and the second touch location if the first touch signal and second touch signal are detected at the same time;
- an indexing unit configured for indexing a command corresponding to the determined group of inputs using the lookup table;
- and
- an inputting unit configured for inputting the indexed command to the electronic device.
