Patent Application
20140240230
The disclosed embodiments generally relate to a control method for a pointer through a touchpad.
A touchpad is a pointing device equipped with a tactile sensor and a specialized surface that can translate a motion and position of a user's fingers on the touchpad into a relative motion and position of a pointer on a screen of an electronic device. However, because of limited sizes of the touchpads, continuous motions across the touchpad are hard to accomplish in one motion. Therefore, there is need for improvement within the art.
Many aspects of the embodiments within this disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
In general, the word “module”, as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language, such as, Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware, such as EPROM. The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of non-transitory computer-readable medium or other storage device. Some non-limiting examples of non-transitory computer-readable media include CDs, DVDs, BLU-RAY, flash memory, and hard disk drives.
Furthermore, when the constant touch operation is located in the corner areas, the computer system 10 moves the pointer along a corresponding diagonal direction.
In one embodiment, to execute a dragging operation on the display 50, the processor 11 further detects a slide motion starting from the lateral area and sliding to the central area 301. The computer system 10 moves the pointer according to the direction of the slide motion. The computer system 10 stops moving the pointer when no contact operation is detected on the touchpad 30. The computer system 10 moves the pointer at a speed relative to a speed of the slide touch operation.
In one embodiment, to distinguish the lateral area from the central area 301, the lateral area and the central area 301 are made of different materials or tactically different.
Step S201: the computer system 10 is utilized by an operation system of the electronic device.
Step S203: the processor 11 detects whether the touchpad 30 receives a slide touch operation from the central area 301. If not, step S203 is repeated. If yes, the process goes to step S207.
Step S207: the computer system 10 moves the pointer across the display 50 according to a direction of the slide touch operation.
Step S209: the processor 11 detects whether the lateral area of the touchpad 30 receives a constant touch operation at an end point of the slide touch operation when the pointer has not reaches an edge of the display 50. If not, the process goes to step S203. If yes, the process goes to step S211.
Step S211: the computer system 10 continues to move the pointer across the display 50. The pointer may be moved at a constant speed.
It is to be understood that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
Depending on the embodiment, certain steps or methods described may be removed, others may be added, and the sequence of steps may be altered. It is also to be understood that the description and the claims drawn for or in relation to a method may include some indication in reference to certain steps. However, any indication used is only to be viewed for identification purposes and not as a suggestion as to an order for the steps.
