Claim 9:
10. The operation method as claimed in claim 6, wherein the stylus-pen mode further includes a step of when it is determined that the stylus pen is in contact with the touchpad, operating in an inking sub-mode that includes steps of:
when it is determined that the cursor is within the handwriting area and that the stylus pen is moved from a start position on the touchpad toward an end position on the touchpad, determining a draw vector related to drawing an imaginary line that connects the start position and the end position on the touchpad;
determining whether the electronic device is an iPad;
when it is determined that the electronic device is an iPad, outputting a third control signal compatible with the HID protocol to the electronic device to enable the electronic device to present, on the display panel, a physical line being drawn in the handwriting area according to the draw vector in a manner that the physical line is drawn from another original point where the cursor originally stayed before drawing and that a step size of drawing the physical line is presented in the relatively low resolution; and
when it is determined that the electronic device is not an iPad, outputting a fourth control signal compatible with the HID protocol to the electronic device to enable the electronic device to present, on the display panel, the physical line being drawn in the handwriting area along the draw vector in a manner that the physical line is drawn from a beginning point that corresponds to the start position on the touchpad and that the step size of drawing the physical line is presented in the relatively high resolution.
