1. An electronic mobile device, comprising:
- a controller;
a display coupled to the controller; and
a touch pad coupled to the controller;
the controller, in one input mode, moving a selection marker on a user interface screen on the display in response to input from the touch pad, and in a second input mode, performing authentication using a sequence of input events from the touch pad matching a predetermined passcode sequence corresponding to one or more directions of successive inputs detected by the touch pad, and in the second input mode being operative to interpret each distinct directional input as an input event corresponding to a fast input or a slow input in the predetermined passcode sequence corresponding to a predetermined sequence of input events corresponding to the fast input or the slow input.

Abstract
An electronic mobile device that includes a controller including at least one processor, for controlling operation of the mobile device, a display coupled to the controller, and a navigational input mechanism coupled to the controller and responsive to user manipulation thereof. The controller, in one input mode, moves a selection marker on a user interface screen on the display in response to user manipulation of the navigational input mechanism, and in a second input mode, authenticates a user of the device in dependence on a sequence of input events resulting from user manipulation of the navigational input mechanism matching a predetermined passcode sequence.

12. A method of authentication of an electronic mobile device having a touch pad that can receive input to facilitate on-screen navigation for the electronic mobile device, the method comprising:
-
receiving a sequence of inputs through the touch pad, the sequence comprising one or more directions of successive inputs; interpreting each distinct directional input detected at the touch pad as either an input event corresponding to a first direction or a second direction and as either a fast input or a slow input; comparing the received sequence of inputs to a predetermined passcode sequence, wherein the predetermined passcode sequence corresponds to a predetermined sequence of the input events corresponding to the first direction or second direction and the fast input or the slow input; and authenticating if the received sequence of inputs matches the predetermined passcode sequence. - View Dependent Claims (13, 14, 15, 16)

17. A non-transitory computer program product comprising a computer readable medium having stored thereon computer executable instructions for authentication of an electronic mobile device having a touch pad that can receive input to facilitate on-screen navigation for the electronic mobile device, the computer executable instructions comprising:
-
receiving a sequence of inputs through the touch pad, the sequence comprising one or more directions of successive inputs; interpreting each distinct directional input detected at the touch pad as either an input event corresponding to a first direction or a second direction and a fast input or a slow input; comparing the received sequence of inputs to a predetermined passcode sequence, the predetermined passcode sequence corresponding to a predetermined sequence of the input events corresponding to the first direction or second direction and the fast input or the slow input; and authenticating if the received sequence of inputs matches the predetermined passcode sequence. - View Dependent Claims (18, 19, 20)
