Abstract
An input device (200) comprises a number of distinct touch areas (230, 232), i.e. areas which are normally in contact with a user while manipulating the device. At least two of such touch areas (230, 232) have corresponding tactual cue generating units (240, 242) for conveying tactual cues via the touch areas (230, 232) to the user. In an application in which the input device (200) is used, the tactual cues can convey location or direction information relating to the application, by independently operating the tactual cue generating units (240, 242).
