METHOD FOR CONTROLLING AN ELECTRONIC DEVICE THAT INCLUDES A TOUCH PAD AND A DISPLAY SCREEN, AND THE ELECTRONIC DEVICE
First Claim
1. A method for controlling an electronic device that includes a touch pad and a display screen, the method comprising the steps of:
- (A) upon detecting a single-object touch on the touch pad when the electronic device operates in a cursor mode, where movement of a cursor in a visual display displayed on the display screen is enabled and controlled in response to and in correspondence with a single-object sliding touch motion on the touch pad, configuring the electronic device to determine whether a time interval that the single-object touch remains substantially stationary on the touch pad reaches a predefined first threshold value; and
(B) when it is determined that the time interval that the single-object touch remains substantially stationary on the touch pad reaches the predefined first threshold value, configuring the electronic device to exit the cursor mode and enter a scrolling mode, where scrolling of the visual display displayed on the display screen is enabled and controlled in response to and in correspondence with a single-object sliding touch motion on the touch pad.

13. An electronic device, comprising:
-
a touch pad for generating a touch signal; a display screen for displaying a visual display thereon; a processor coupled to said touch pad for receiving the touch signal, and further coupled to said display screen for generating the visual display to be displayed on said display screen, said processor enabling and controlling movement of a cursor in the visual display in response to and in correspondence with the touch signal that corresponds to a single-object sliding touch motion on said touch pad when said processor operates in a cursor mode, said processor enabling and controlling scrolling of the visual display in response to and in correspondence with the touch signal that corresponds to a single-object sliding touch motion on said touch pad when said processor operates in a scrolling mode; and a control module coupled to said touch pad for receiving the touch signal therefrom, and further coupled to said processor for controlling operation of said processor in one of the cursor mode and the scrolling mode; wherein when said control module controls said processor to operate in the cursor mode, upon receipt of the touch signal indicating a single-object touch on said touch pad, said control module determines whether a time interval that the single-object touch remains substantially stationary on said touch pad reaches a predefined first threshold value with reference to the touch signal, and controls said processor to exit the cursor mode and enter the scrolling mode when the time interval that the single-object touch remains substantially stationary on said touch pad is determined to have reached the predefined first threshold value. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
