摘要:
Methods and systems for key arrangements including a plurality of keys arranged in a plurality of rows and a plurality of columns. At least one of the plurality of keys has a predetermined key width determined by dividing a face width of a device by a number of the plurality of columns. Each row of the plurality of rows has a first key located at a first end, a second key located at a second end, at least two interior keys located between the first and second keys. The respective widths of the first key and the second key are determined by subtracting a predetermined amount from the predetermined key width such that the respective widths of the first and second keys are smaller than interior key widths of the at least two interior keys.

A key arrangement includes a plurality of keys that are arranged in a regular grid of rows and columns. The columns include a first column, a last column, and at least one middle column. The keys in the first and last columns are smaller than the keys in the at least one middle column. A method for improving the ergonomics of a key arrangement on a keyboard of a fixed size is provided. A method for designing a key arrangement for a mobile communication device is also provided.

A wireless handheld device comprises a lower casing having a bottom end and a top end and a lid having a bottom end and a top end. The top end of the lid is rotatably coupled to the top end of the lower casing with at least one hinge component such that the handheld device is rotatable from a closed position to an open position and from an open position to a closed position. The lid and the lower casing have adjacent facing surfaces when in the closed position. When the wireless handheld device is in the closed position, at least the bottom end of the lid is displaceable relative to the lower casing generally in an axial direction of the hinge component such that the facing surfaces become misaligned for easy grasping of the lower casing and the lid.

A handheld communication device having a reconfigurable keyfield and a display screen upon which characters are displayed. A plurality of actuable input keys makeup the keyfield, and each has at least one character associated therewith and an engageable top surface for actuation. A microprocessor is configured to receive data indicative of an actuated input key and to output data indicative of an associated character determined to correspond to the indicated input key. At least one of the plurality of actuable input keys is mounted to the handheld communication device by an adjustable interconnection configurable between at least first and second operating orientations. In the first operating orientation, the engageable top surface of the at least one input key faces a first direction and in the second operating orientation the engageable top surface of the at least one input key faces a second direction.

A system and method of selecting a character for display in a communication device having a display and a reduced-key keyboard is provided. One of the plurality of keys on the reduced-key keyboard is selected and a default letter associated with the selected key is displayed. A backspace key is selected to display a cursor in the position of the character on the display. The key associated with the default character is selected again and an alternate character associated with the selected key is displayed in place of the default letter.

A device is disclosed for use in two different orientations. In one orientation, the keyboard is exposed to the user. This orientation is named the landscape orientation because the device will be positioned such that its width is larger than its height. The user would opt for the landscape orientation for tasks that require the keyboard, such as inputting data, drafting emails, sending emails, and other functions typically associated with a standard computer. The other orientation is named the portrait orientation because the device will be positioned such that its height is larger than its width. In addition, the keyboard is not used in this orientation and therefore hidden away. The user would opt for the portrait orientation for tasks such as making and receiving telephone calls and for reading documents and emails. The device detects the orientation positioned by the user and modifies the elements shown on the display screen so that they are presented in the correct orientation to the user.

A handheld electronic device useful for wireless communication has a keyboard including a plurality of externally accessible keys. The keys can be disabled (i.e. the keyboard can be locked) to prevent accidental actuation thereof by using the navigation tool which has a depressible rolling member. Thus, for example, depression of the rolling member twice in succession or pressing and holding the rolling member down temporarily enables the keyboard lock. The lock can be disabled simply by depressing the rolling member and at least one other key.

A wireless communications system may include a user-wearable device including a clasp having open and closed positions, a first wireless security circuit (WSC), and a first controller coupled to the clasp and the first WSC. The system may further include a mobile wireless communications device including a portable housing, an input device(s), a second WSC carried by the portable housing and configured to communicate with the first WSC when in close proximity therewith, and a second controller carried by the portable housing and coupled to the second WSC and the input device(s). The second controller may be configured to enable mobile wireless communications device(s) function based upon a manual entry of an authentication code via the input device(s), and bypass the manual entry and enable the mobile wireless communications device function(s) based upon a communication from the user-wearable device and a position of the clasp.
