Abstract

A selective call radio (10), including a housing (12), has a display (18) and touchpad (22) of the same size. The display is mounted to a surface on one side of the housing, and the touchpad is mounted to another surface on an opposite side of the housing, directly opposite the display. A screen surface of the display and a touch surface of the touchpad are parallel and have a same number of edges. Sliding of a user'"'"'s fingertip on the touchpad in a right-to-left direction causes movement of a pointer (26) in a left-to-right direction, and vice versa. Movement on the touchpad causes movement in an identical amount on the display.

Claims

1. A selective call radio, comprising:

a housing having a first surface and a second surface, the first surface being approximately parallel to the second surface;

a display mounted to the housing at the first surface; and

a touchpad mounted to the housing at the second surface.

2. The selective call radio of claim 1, in which dimensions of the display and dimensions of the touchpad are substantially identical.

3. The selective call radio of claim 2, in which the display has a plurality of edges and the touchpad has a same number of corresponding edges and each of the plurality of edges of the display are parallel to each of the corresponding edges of the touchpad.

4. The selective call radio of claim 3 in which the housing has at least one additional surface adjacent to both the first surface and the second surface, and the touchpad is mounted such that a distance between an edge of the touchpad and the at least one additional surface is substantially equal to the distance between a corresponding edge of the display and the at least one additional surface.

5. A selective call radio housing having a first surface and a second surface, the second surface being opposite the first surface, comprising:

a display mounted on the first surface, the display having a substantially flat screen surface; and

a touchpad mounted on the second surface, the touchpad having a substantially flat touch surface.

6. The selective call radio housing of claim 5 in which the screen surface is substantially parallel to the touch surface.

7. The selective call radio housing of claim 6, in which the touchpad is mounted directly opposite the display.

8. The selective call radio housing of claim 7 in which dimensions of the display and dimensions of the touchpad are substantially identical.

9. A system for controlling a selective call radio, comprising:

a selective call radio housing;

a touchpad fixed to the selective call radio housing and electrically coupled to the selective call radio, the touchpad having an axis;

a display for displaying a pointer of a graphical user interface, the display fixed to the selective call radio housing and electrically coupled to the selective call radio, the display having a corresponding axis; and

means for interconnecting the display and the touchpad such that a component of touching movement on the touchpad along the axis produces a component of movement of the pointer on the display along the corresponding axis in a reverse direction.
