Mobile station user interface, and an associated method, facilitating usage by a physically-disabled user
First Claim
1. In a mobile station having an actuation keypad formed of an array of actuation keys, each of the actuation keys of said actuation keypad axially displaceable between an unactuated position and an actuated position, said mobile station operable in a radio communication system, an improvement of a user interface of facilitating usage thereof by a physically-disabled user, said user interface comprising:
- a key mat comprising a plurality of concave-shaped face covers, at least one of said plurality of concave-shaped face covers corresponding with and disposed adjacent to an actuation key of said array of actuation keys said at least one concave-shaped face cover forming a force-receiving surface for facilitating reception of an actuation force from a mouth pin, thereby causing axial displacement of the adjacent actuation key out of the unactuated position and into the actuated position.

Abstract
A user interface, and an associated method, facilitates operation of a mobile station by a physically-disabled user. In one implementation, concave-shaped face covers are provided for the telephonic keypad of a mobile station to facilitate its usage by a physically-disabled user. In another implementation, the mobile station is provided with a TTY (telecommunications device), also to facilitate operation of the mobile station by a physically-disabled user. And, in another implementation, a location-request signal generator, carriable by a user, generated a location-request signal upon actuation by the user. The mobile station includes a local receiver for receiving the location-request signal and an annunciator for annunciating reception of the location-request signal. If the mobile station becomes misplaced, a user actuates the location-request signal generator, and the annunciation signal generated responsive to detection of such signal at the mobile station facilitates location of the mobile station.

11. In a mobile station operable in a radio communication system, an improvement of a user interface for facilitating usage thereof by a physically-disabled user, said user interface comprising:
-
an actuation keypad formed of an array of actuation keys, each of the actuation keys of said actuation keypad displaceable between an unactuated position and an actuated position;
a plurality of concave-shaped face covers, said plurality of concave-shaped face covers at least corresponding in number with the actuation keys of which said actuation keypad is formed, each of said concave-shaped face covers disposed adjacent to an actuation key of said actuation keypad, each of said concave-shaped face covers forming a force receiving surface for facilitating reception of an actuation force from a mouth pin causing axial displacement of the actuation key upon which said face cover is seated out of the unactuated position and into the actuated position;
a mobile-station location request signal generator housed separately from the mobile station and carriable by the user, said mobile-station location request generator actuable by the user to generate a location request signal for transmission to the mobile station; and
an annunciator positioned together with the mobile station and coupled to receive indications of the mobile-station local request signal generated by said location request signal generator, said annunciator for generating an annunciation signal responsive to reception of the indications of the location request signal. - View Dependent Claims (12)

13. In a mobile communication system operable in a radio communication and having transceiver circuitry for receiving forward link signals and for transmitting reverse link signals, an improvement of a user interface for facilitating usage thereof by a physically-disabled user, said user interface comprising:
-
an actuation keypad formed of an array of actuation keys, each of the actuation keys of said actuation keypad axially displaceable between an unactuated position and an actuated position;
a key mat comprising a plurality of concave-shaped face covers, said plurality of concave-shaped face covers at least corresponding in number with the actuation keys of which said actuation keypad is formed, each of said concave-shaped face covers seated upon an actuation key of said actuation keypad, each of said concave-shaped face covers forming a force receiving surface for facilitating reception of an actuation force from a mouth pin causing axial displacement of the actuation key upon which said face cover is seated out of the unactuated position and into the actuated position; and
a TTY (Text Telephone) device coupled to the transceiver circuitry, said TTY device for converting indications of the downlink signals into text form and for receiving text inputs to be converted into the forward link signals. - View Dependent Claims (14)

15. In a method for entering user inputs at a mobile station having an actuation keypad, formed of an array of actuation keys, at the mobile station, the actuation keys of the actuation keypad axially displaceable between an unactuated position and an actuated position, said mobile station operable in a radio communication system, an improvement of a method for facilitating use of the mobile station by a physically-disabled user, said method comprising:
-
covering the actuation keypad with a key mat comprising a plurality of concave-shaped face covers such that at least one of the concave-shaped face covers seats upon a corresponding actuation key, the at least one concave-shaped face cover forming a force-receiving surface for facilitating reception of an actuation force from a mouth pin to displace the actuation key associated therewith between the unactuated and actuated positions, respectively; and
selectively applying axial displacement forces upon selected ones of the concave-shaped face covers. - View Dependent Claims (16)
providing a TTY device in communication with the transceiver circuitry;
providing indications of the downlink signals to the TTY device; and
displaying the indications of the downlink form in text form upon the TTY device.
