Abstract

A touch device operation method is provided. The touch device input method comprises the steps as follows. A display frame is provided on the touch display module of the touch device, wherein the display frame comprises a software keyboard having virtual keys. A touch input on the touch display module is detected. The touch input is determined to correspond to a triggered key of one of the virtual keys. An amount of characters that the triggered key has is determined. When the amount of characters is not larger than one, the character is displayed on the display frame. When the amount of characters is larger than one, the virtual keys are updated to output under-selection characters in a neighboring area of the triggered key. A displacement of the touch input is detected to select one of the virtual keys. A touch device is disclosed herein as well.
