Abstract
Abstract A palmtop computer for entering characters using one or more input modes. In one example, a physical sensor is coupled to select the input mode. The physical sensor may be in the form of a button, rocker switch, dial, pressure strip, moveable bar, or accelerometer mounted to the device. The physical sensor may also be mounted to a pen. In another example, a ridge is formed on the digitizer pad and positioned to define input regions associated with particular input mode. In another example, a border is formed around the digitizer pad. The border includes a ridge coupled to select the input mode. The digitizer pad may also be textured. A first textured region is associated with one input mode and a second textured region is associated with another input mode.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
56 words
A palmtop computer for receiving input of characters, the computer comprising: a casing; a digitizer pad coupled to said casing; and, a bar mounted with said casing and positioned over said digitizer pad to define a first input region and a second input region, wherein said bar maybe moved to select a character type input mode.
Claim 2
Dependent Claim
56 words
A palmtop computer for receiving input of characters, the computer comprising: a casing; a digitizer pad coupled to said casing; and, a bar mounted with said casing and positioned over said digitizer pad to define a first input region and a second input region, wherein said bar maybe moved to select a character type input mode.
Claim 3
Dependent Claim
32 words
The palmtop computer of claim 1 , wherein said bar may be moved to select a first input mode for said first region and a second input mode for said second region.
Claim 4
Dependent Claim
20 words
The palmtop computer of claim 1 , wherein bar may be used to cycle through a plurality of input modes.
Claim 5
Dependent Claim
55 words
A palmtop computer for receiving input of characters, the computer comprising: a casing; a digitizer pad coupled to the casing; and a ridge formed on the digitizer pad to define a first input region associated with a first character type input mode and a second input region associated with a second character type input mode.
Claim 6
Dependent Claim
55 words
A palmtop computer for receiving input of characters, the computer comprising: a casing; a digitizer pad coupled to the casing; and a ridge formed on the digitizer pad to define a first input region associated with a first character type input mode and a second input region associated with a second character type input mode.
Claim 7
Dependent Claim
28 words
The palmtop computer of claim 4 , wherein said first input region includes a first textured region and said second input region includes a second distinct textured region.
Claim 8
Dependent Claim
31 words
The palmtop computer of claim 4 , further comprising: a second ridge formed on the digitizer pad to define, within said first input region, a first sub-region and a second sub-region.
Claim 9
Dependent Claim
31 words
The palmtop computer of claim 6 , further comprising: a third ridge formed on the digitizer pad to define, within said second input region a third sub-region and a fourth sub-region.
Claim 10
Dependent Claim
18 words
The palmtop computer of claim 7 , wherein each said sub-region is assigned a character type input mode.
Claim 11
Dependent Claim
70 words
A palmtop computer for receiving input of characters, the computer comprising: a casing; a digitizer pad coupled to the casing; and a border formed around the digitizer pad, the border including an actuable ridge to select a character type input mode, wherein said actuable ridge includes a stepped inner edge that may be actuated by applying a pressure to said stepped inner edge to select a character type input mode.
Claim 12
Dependent Claim
70 words
A palmtop computer for receiving input of characters, the computer comprising: a casing; a digitizer pad coupled to the casing; and a border formed around the digitizer pad, the border including an actuable ridge to select a character type input mode, wherein said actuable ridge includes a stepped inner edge that may be actuated by applying a pressure to said stepped inner edge to select a character type input mode.
Claim 13
Dependent Claim
14 words
