Abstract

One embodiment of the present invention provides a portable computing device comprising a housing including a keyboard. The embodiment also includes a first pointing device coupled to the housing, as well as a second pointing device coupled to the housing between the keyboard and a first edge of the housing. The embodiment additionally includes a plurality of buttons disposed on the housing so that at least one button is located between the first pointing device and the second pointing device, and at least one button is located between the glide point and the first edge of the housing. In another embodiment, the plurality of buttons is movably disposed on the housing so that when buttons are located in a first position, at least one button is located between the first pointing device and the second pointing device, and when buttons are located in a second position, at least one button is located between the second pointing device and the first edge of the housing. The term pointing devices refers to any manually operated input device that can be used to move a cursor around a computer display, such as a mouse, a track ball, a pointing stick or a glide point.

Claims

1. A method for configuring data input devices in a portable computer, the method comprising:

fixedly mounting a rectangular data input module into a rectangular mounting cavity in a housing of the portable computer in a first orientation so that a button on the rectangular input module can be used with a first pointing device located on the housing of the portable computer;

removing the rectangular data input module from the housing;

rotating the rectangular data input module 180 degrees;

fixedly mounting the rectangular data input module into the rectangular mounting cavity in the housing in a second orientation so that the button on the rectangular input module can be used with a second pointing device located on the rectangular data input module; and

inputting commands manually into the data input module.

2. The method of claim 1, wherein the inputting of commands into the data input module includes operating a button.

3. The method of claim 1, wherein the inputting of commands into the data input module includes operating a glide point.

4. The method of claim 1, wherein the inputting of commands into the data input module includes operating a track ball.

5. The method of claim 1, wherein the inputting of commands into the data input module includes operating a pointing stick.

6. The method of claim 1, further comprising:

receiving input from the first pointing device and the second pointing device;

keeping track of which pointing device is most recently used;

if the first pointing device is most recently used, receiving input from a button associated with the first pointing device while ignoring input from a button associated with the second pointing device; and

if the second pointing device is most recently used, receiving input from the button associated with the second pointing device while ignoring input from the button associated with the first pointing device.

7. The method of claim 1, further comprising:

receiving input from a keyboard disposed on the housing; and

displaying an output to a display disposed on the housing.

8. The method of claim 1, further comprising:

determining if configuration information stored in the portable computer indicates that the first pointing device or the second pointing device is to be used;

if the first pointing device is to be used, receiving input from a button associated with the first pointing device; and

if the second pointing device is to be used, receiving input from a button associated with the second pointing device.
