Abstract: For overcoming a defect that a conventional surface capacitive touch panel is not capable of determining more than two touch points so that the surface capacitive touch panel is not capable of determining any multi-touch commands, a type of a multi-touch command is determined by detecting relative movements between touch points and corresponding intermediate points on the surface capacitive touch panel, where the relative movements may be indicated by relative distances or relative directions. Therefore, a bottleneck that the surface capacitive touch panel cannot be used for detecting a type of a multi-touch command may be overcome, and the surface capacitive touch panel may be widely applied for touch panels required to detect multi-touch commands.
