Abstract: A computer input device having a housing and a finger-engagable scrolling device. A portion of the scrolling device is endlessly rotatable about a first axis to preferably cause vertical scrolling of an image on a display. The scrolling device is pivotally movable relative to the housing about a second axis perpendicular to the first axis. The first axis and the second axis may lie in a common plane or otherwise be close to one another to provide a large range of possible angular motion. A sensor is preferably positioned within the finger-engagable scrolling device for rotational movement of the rotational portion of the finger-engagable scrolling device. A pivot sensor may be provided on the second axis or laterally disposed from the scrolling device. A cover with an aperture may be provided over the scrolling device to help prevent dust and other contaminates from entering the housing through the opening for the scrolling device.

Abstract: A keyboard having an improved function key section and an improved editing section. A row of keys is located behind the alphanumeric section. The row of keys includes individual predefined command keys. The groupings of the predefined command keys may be made based on the functionality of the keys, their use on common applications or programs, and/or other by other grouping techniques. Further, the keys within each group may be ordered based on chronological order of use, frequency of use, or by a correlation to a graphical toolbar. Each of at least two adjacent groupings of keys behind the alphanumeric region consists of exactly three keys, and each of at least three adjacent key groupings in the entire row consists of exactly three keys. The keys are each capable of functioning as predetermined command keys in a first mode and standard function keys in a second mode.

Abstract: A keyboard having an input region that provides a set of input elements designed to complement a separate pointing device such as a computer mouse. These input elements enable both the dominant and non-dominant hand to work easily together to perform various functions, which in turn, makes “consumption” and “composition” tasks more efficient. The input region may be spaced laterally from the alphanumeric or “QWERTY” section of the keyboard. The elements include a scrolling member, first and second groups of keys, and an application switching device. The scrolling member may take the form of a rotatable member. The rotatable member may have an asymmetric outer profile and/or be frustum-shaped. The first group of keys preferably includes a Back key and a Forward key. The first group of keys and the scrolling member make performing “consumption” tasks more efficient. The second group of keys preferably includes a Cut key, a Copy key, and a Paste key.

Abstract: A keyboard having an improved numeric section and an improved numeric key cluster in the numeric section. The keyboard preferably includes an alphanumeric or QWERTY section and an editing section laterally disposed from the numeric section. A row of function keys is preferably provided above at least the numeric key cluster. The present invention also provides keys frequently used with the numeric section within, or in close proximity to, the key cluster in the numeric section. A Tab key or an Equals “=” key has been provided within the key cluster for improved efficiency. Additionally, a row, preferably including four keys, is provided above and in close proximity to the numeric key cluster. These keys preferably include a Left Parenthesis “(” key, a Right Parenthesis “)” key, a Backspace key, and a Tab key or an Equals “=” key, whichever is not provided within the numeric key cluster.
