## Abstract

A multifunctional handheld device capable of operating in different modes includes a single input arrangement that provides inputs for each mode of the multifunctional handheld device. The single input arrangement includes at least an input pad that provides signals when touched or pressed. The input pad may for example be a touch pad. The input pad is divided into one or more input areas that change in accordance with the current mode of the multifunctional handheld device. The multifunctional handheld device also includes a display device that presents graphical elements to indicate the configuration of the input areas at the input pad. Each mode of the multifunctional handheld device provides a different configuration of input areas and graphical elements associated therewith.

## Claims

### Claim 1

A clickable trackpad, including:
a touch surface;
at least one depressible mechanical button capable of being activated by pressure at the touch surface; and
a processor capable of
designating a plurality of regions on the touch surface as click regions,
detecting a mechanical click of the trackpad due to an application of pressure anywhere on the touch surface, the mechanical click itself being nondeterminative of a location of a touch on the touch surface,
detecting a touch at a particular click region at about a same time as the detection of the mechanical click, and
determining an operation to be performed in accordance with the particular click region.

### Claim 2 (depends on 1)

The clickable trackpad of claim 1, wherein the touch surface is unmarked.

### Claim 3 (depends on 1)

The clickable trackpad of claim 1, the processor further capable of allocating an area of one or more of the click regions in accordance with button usage patterns.

### Claim 4 (depends on 1)

The clickable trackpad of claim 1, the processor further capable of allocating a location of one or more of the click regions in accordance with button usage patterns.

### Claim 5 (depends on 1)

The clickable trackpad of claim 1, the processor further capable of dynamically designating the one or more click regions in accordance with current device usage.

### Claim 6 (depends on 1)

The clickable trackpad of claim 1, the processor further capable of triggering a left-click action upon the detection of the touch and mechanical click if the particular click region is a primary click region on the touch surface.

### Claim 7 (depends on 1)

The clickable trackpad of claim 1, the processor further capable of triggering a right-click action upon the detection of the touch and mechanical click if the particular click region is a secondary click region on the touch surface.

### Claim 8

A method of initiating an operation on a clickable trackpad having at least one depressible mechanical button, comprising:
designating a plurality of regions on the trackpad as click regions;
detecting a mechanical click of the trackpad due to an application of pressure anywhere on a surface of the trackpad, the mechanical click itself being nondeterminative of a location of a touch on the trackpad;
detecting a touch at a particular click region at about a same time as the detection of the mechanical click; and
determining an operation to be performed in accordance with the particular click region.

### Claim 9 (depends on 8)

The method of claim 8, wherein the trackpad is unmarked.

### Claim 10 (depends on 8)

The method of claim 8, further including allocating an area of one or more of the click regions in accordance with button usage patterns.

### Claim 11 (depends on 8)

The method of claim 8, further including allocating a location of one or more of the click regions in accordance with button usage patterns.

### Claim 12 (depends on 8)

The method of claim 8, further including dynamically designating the one or more click regions in accordance with current device usage.

### Claim 13 (depends on 8)

The method of claim 8, further including triggering a left-click action upon the detection of the touch and mechanical click if the particular click region is a primary click region on the trackpad.

### Claim 14 (depends on 8)

The method of claim 8, further including triggering a right-click action upon the detection of the touch and mechanical click if the particular click region is a secondary click region on the trackpad.

### Claim 15

A clickable trackpad, including:
means for designating a plurality of regions on the trackpad as click regions;
means for detecting a mechanical click of the trackpad due to an application of pressure anywhere on a surface of the trackpad, the mechanical click itself being nondeterminative of a location of a touch on the trackpad;
means for detecting a touch at a particular click region at about a same time as the detection of the mechanical click; and
means for determining an operation to be performed in accordance with the particular click region.

### Claim 16 (depends on 15)

The clickable trackpad of claim 15, wherein the trackpad is unmarked.

### Claim 17 (depends on 15)

The clickable trackpad of claim 15, further including means for allocating an area of one or more of the click regions in accordance with button usage patterns.

### Claim 18 (depends on 15)

The clickable trackpad of claim 15, further including means for allocating a location of one or more of the click regions in accordance with button usage patterns.

### Claim 19 (depends on 15)

The clickable trackpad of claim 15, further including means for dynamically designating the one or more click regions in accordance with current device usage.

### Claim 20 (depends on 15)

The clickable trackpad of claim 15, further including:
triggering a left-click action upon the detection of the touch and mechanical click if the particular click region is a primary click region on the trackpad, and
triggering a right-click action upon the detection of the touch and mechanical click if the particular click region is a secondary click region on the trackpad.
