Portable electronic apparatus, and a method of controlling a user interface thereof

摘要

A portable electronic apparatus has a display, keypad, sensor and controller. Keys of the keypad are distributed within a keypad area in at least a first plane and are arranged for user actuation transversally to the first plane to provide a first type of user input. The sensor is positioned to sense navigating user actuation at the keypad area in or coincident with the first plane to provide a second type of user input. The controller is configured to control a focus position on the display in response to the second type of user input; associate a plurality of display subareas of the display with respective keys of the keypad; and accept, for user input of the second type, user actuation of an actuated key among the keys as a selection of a selectable item presented at the focus position in a particular display subarea associated with the actuated key.

主权项

1. A portable electronic apparatus having:
a display; a keypad having a plurality of keys, the keys being distributed within a keypad area in at least a first plane, and the keys being arranged for key-pressing user actuation transversally to the first plane so as to provide a first type of user input; a sensor positioned to sense navigating user actuation at the keypad area in or coincident with the first plane so as to provide a second type of user input; and a controller configured to: control a focus position on the display in response to user input of the second type; associate a plurality of display subareas of the display with respective keys of the keypad; and accept, for user input of the second type, a key-pressing user actuation of an actuated key among the keys as a selection of a selectable item presented at the focus position in a particular display subarea associated with the actuated key, wherein the controller is configured, in a cursor control mode intended for input of the second type, to: receive content to be presented on the display; determine one or more pieces of clickable content included in the received content; and for at least one piece of clickable content, rearrange this piece of clickable content with respect to the received content to be presented, such that the piece of clickable content will appear, when the received content is presented on the display, as a selectable item in a particular display subarea associated with a particular key of the keypad, and wherein the controller is configured to perform the rearranging as a result of a finding that the piece of clickable content would have appeared, when presented, at a display location which would not have fallen within any of the display subareas or at a display location which would have fallen within a display subarea that contains another piece of clickable content, and that the particular display subarea is available in the sense that it would not have contained a piece of clickable content.
