Abstract
Official abstract text for this publication.
An input-key control device is mounted on an apparatus having a plurality of operating modes and controls a plurality of input keys that receive input provided by a user. The input-key control device includes: a key-related-information storage unit that stores the operating modes and key-identifying information in association with each other, the key-identifying information being information for identifying an operable input key; an input-key identifying unit that identifies, when the operating mode is switched, an input key which has newly become operable as a result of the switching of the operating mode by comparing the key-identifying information associated with the operating mode before the switching and the key-identifying information associated with the operating mode after the switching; and a light-emission control unit that causes a lighting manner of a light-emitting element that illuminates the input key identified by the input-key identifying unit to differ.
First claim
Opening claim text (preview).
What is claimed is: 1. An input device, comprising: a plurality of sections, each section comprising at least one key and each section occupying a different region of a user interface; and a controller which causes illumination of the at least one key of a second section of the plurality of sections, in response to a key of a first section being activated, the at least one key which is illuminated providing input related to a function of the key of the first section which has be…
