Abstract

An assembly for attachment to a portable computer is described including a touchpad and associated buttons where the touchpad is mounted on one surface of the assembly and the associated “mouse” buttons are mounted on the reverse surface, the two surfaces facing in substantially opposite directions. The buttons are mounted in close proximity to the reverse-mounted touchpad such that the user can operate both the touchpad and the buttons simultaneously with the thumb and one or more fingers of the same hand. In one embodiment, the touchpad faces away from the user and is operated by a finger that is not the user'"'"'s thumb. In another embodiment, the touchpad faces the user and is operated by the user'"'"'s thumb. For all embodiments, the associated “mouse buttons” are mounted facing in the reverse direction relative to the touchpad.

Claims

1. An assembly configured for temporarily attaching to a display panel of a conventional folding clamshell style portable computer having a base unit with keyboard and a separate display panel hinged to the base unit, the assembly including a touchpad and associated buttons, comprising:

a touchpad mounted on a first outer surface of the assembly;

one or more buttons mounted on a second outer surface of the assembly;

wherein said first and second outer surfaces face in substantially opposite directions;

wherein the display panel of the conventional folding clamshell style portable computer has no special provision for attachment of the assembly including the touchpad and associated buttons;

wherein the assembly is designed to clip onto a side edge of the display panel of the portable computer;

wherein the assembly including the touchpad and associated buttons has a generally J-shaped configuration;

wherein when attached to the side edge of the display panel of the portable computer, a portion of the assembly is located behind the display panel; and

wherein the portion of the assembly located behind the display panel is larger than a portion of the assembly located in front of the display panel.

2. The assembly of claim 1 wherein the one or more buttons face a user and are most readily operated with the user'"'"'s thumb.

3. The assembly of claim 1 wherein the touchpad faces in a direction substantially away from a user and is most readily operated with a finger of the user, not including the user'"'"'s thumb.

4. An assembly configured for temporarily attaching to a display panel of a conventional folding clamshell style portable computer having a base unit with keyboard and a separate display panel hinged to the base unit, the assembly including a touchpad and associated buttons, comprising:

a touchpad mounted on a first outer surface of the assembly;

one or more buttons mounted on a second outer surface of the assembly;

wherein said first and second outer surfaces face in substantially opposite directions;

wherein the display panel of the conventional folding clamshell style portable computer has no special provision for attachment of the assembly including the touchpad and associated buttons;

wherein the assembly including the touchpad and associated buttons has a generally J-shaped configuration including a first structure comprising the first outer surface and a second structure comprising the second outer surface, and also including a third structure connecting the first and second structures; and

wherein when attached to the display panel of the conventional folding clamshell style portable computer, the first outer surface faces toward away from a user and the second outer surface faces away from toward the user; and

wherein the first structure comprising the first outer surface is larger than the second structure comprising the second outer surface.
