Abstract

A method for preventing a false activation of a touch pad of a portable computer is provided. The portable computer includes a display and a base assembly. The base assembly includes a keyboard and a touch pad. The keyboard includes keys and the touch pad has a touch area. In the method, the touch area is divided into a plurality of subareas. Each key corresponds to at least one subarea. A key input is detected. If the key input is detected, the at least one subarea corresponding to the inputting key are maintained as untouchable.

Claims

1. A method for preventing a false activation of a touch pad of a portable computer, the portable computer comprising a display and a base assembly, the base assembly comprising a keyboard and the touch pad, the keyboard comprising a plurality of keys, the touch pad defining a touch area, the method comprising:

dividing the touch area into a plurality of subareas, each of the plurality of keys corresponding to at least one of the plurality of subareas;

detecting whether there is a key input by an inputting one of the plurality of keys; and

maintaining the at least one of the plurality of subareas corresponded to the inputting one of the plurality of keys being untouchable if the key input is detected.

2. The method of claim 1, wherein the touch area comprises easy palm rest regions and uneasy palm rest regions, palms of a user easily rest on the easy palm rest regions when inputting by the plurality of keys, the palms of the user barely or rarely rest on the uneasy palm rest regions when inputting by the plurality of keys, and the easy palm rest regions are set as some of the plurality of subareas corresponding to the plurality of keys.

3. The method of claim 1, wherein the base assembly defines a surface and two opposite sides, the keyboard and the touch pad covers the entire surface of the base assembly and both the keyboard and the touch pad extend from one of the two opposite sides to the other one of the two opposite sides along a length extending direction.

4. The method of claim 1, wherein the plurality of subareas comprise left side subareas, right side subareas, and central subareas along a length extending direction of the touch area, an amount of the left side subareas and the right side subareas is more than that of the central subareas.

5. The method of claim 4, wherein a size of the left subareas and the right side subareas is smaller than that of the central subareas.

6. The method of claim 1, wherein the plurality of subareas covers the entire touch area.

7. The method of claim 1, wherein the plurality of subareas adjoin in sequence and at least two adjacent of the plurality of subareas partially overlap with each other.

8. The method of claim 1, wherein the plurality of subareas comprise left side subareas, right side subareas, and central subareas along a length extending direction of the touch area, the left side subareas are partially overlapped with each other, the right side subareas are partially overlapped with each other, and the central subareas adjoin but do not overlap with each other.

9. The method of claim 1, wherein the plurality of subareas adjoin in sequence and every two adjacent to the plurality of subareas partially overlap with each other.

10. The method of claim 1 further comprising a step of setting a lock time period to keep at least one untouchable subarea of the plurality of subareas to be untouchable within the lock time period.

11. The method of claim 10 further comprising further detecting the key input if a time period of the at least one untouchable subarea being untouchable exceeds the lock time period, if there is still no key input detected, activating the at least one untouchable subarea to be touchable.

12. The method of claim 10, wherein the lock time period is a value in a range from about 0.5 seconds to about 1 second.
