DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows a mobile communication apparatus 100 comprising a display 102 and a rotating input means 104. The mobile communication apparatus further comprises a plurality of keys 106, a speaker 108, a microphone 110, an antenna 112, and a processor (not shown) for controlling all functions and devices of the mobile communication apparatus 100. Among these functions, a central function is user interface. A common way to implement the user interface in mobile communication apparatuses is a menu 114, where a user is enabled to select among a plurality of items. The items are presented on the display 102, and can be a text list, a plurality of icons, or a plurality of tabs, or any combination thereof. As the menus become more complex as the mobile communication apparatuses become more complex, while the size of the display 102 is limited because of the limited size of a feasible mobile communication apparatus 100. Often, this implies that not all items can be shown at a time in the display. Therefore, some indication of what part of the items which is shown is needed. One way to indicate this is to use a scroll bar 116. However, to enable a user to find certain items in the menu easier, the rotating input means 104 is provided with a tactile feedback, such that the user will feel an increased resistance in turning the rotating input means 104. Alternatively or additionally, a sound can be presented by a buzzer (not shown) or the speaker 108, and/or a vibrating function of the mobile communication apparatus can also provide feedback. The tactile, sound, or vibration feedback can appear when a last selected item is passed or reached when scrolling, when the end of a list is passed or reached, or when certain parts of the items are passed or reached. The items emanating in a tactile feedback can be preset, selectable by user settings, or dynamic depending on detected use of the mobile communication apparatus.
FIG. 2 shows a mobile communication apparatus 200 according to an embodiment of the present invention, similar to the one of FIG. 1, with a display 202 and a rotating input means 204. However, to enable a user to find certain items in the menu easier, the rotating input means 204 is provided with a graphical feedback. The graphical feedback can comprise a first marker 206 indicating a fixed position, and a second marker 208 indicating a position at the rotating input means corresponding to a certain item in the menu. To get to said certain item, the user has to turn the rotating input means such that the angular positions of the first and second markers 206, 208 correspond. The graphical feedback can be combined with tactile, sound and/or vibration feedback.
FIG. 3 shows a mobile communication apparatus 300 according to a further embodiment of the present invention. Here, a graphical feedback comprises a first marker 302 indicating a fixed position, and a second and a third marker 304, 306, each indicating a position at the rotating input means corresponding to a certain item in the menu. The visual appearance of the second and third markers 304, 306 differ, e.g. by different colors or different patterns. For example, the second marker 304 can indicate the angular position corresponding to a last used item and the third marker 306 can indicate the angular position corresponding to an end of the list. The graphical feedback can be combined with tactile, sound and/or vibration feedback.
FIG. 4 shows a mobile communication apparatus 400 according to a further embodiment of the present invention. Here, a graphical feedback comprises a marked area 402 corresponding to a certain partition of selectable items. For example, the partition of items can be messaging services which may be handy to find quickly. One or more areas can be marked in similar or different ways, e.g. different color or pattern. The graphical feedback can be combined with tactile, sound and/or vibration feedback.
FIGS. 1-4 have been used to show a plurality of feedback alternatives for rotating input means. However, an embodiment of the present invention is a combination of these feedback alternatives. For example, one or some items can be associated with a sound feedback, another or others can be associated with a tactile feedback, another with vibration feedback, etc. Some items can be associated with two or more of the above mentioned feedback alternatives.
The markers of the aforementioned embodiments are implemented by using a transparent wheelpad for the rotating input means. Below the wheelpad, an addressable indicator is provided. By addressing different parts, by control of the processor of the mobile communication apparatus, the markers are provided according to the angular position of the certain items in relation to the actual position of the wheelpad.
FIG. 5 schematically shows an implementation of a rotating input means 500. The implementation comprises a wheelpad 502, a sensor 504 for detecting angular movements of the wheelpad 502, and a processor 506. When the wheelpad 502 is rotated in any direction, the sensor 504 detects how much and in which direction the wheelpad 502 is rotated. The sensor 504 generates a signal accordingly, and sends the signal to the processor 506. The processor outputs a feedback signal associated with a selectable item accordingly, and the feedback signal controls provision of a marker by an addressable indicator (not shown) below the wheelpad, or provision of a tactile feedback by increasing rotation resistance of the wheelpad or actuating a vibration function or a sound presentation. Increased resistance can be provided by means integrated in the sensor 504, or by serarate means (not shown), e.g. by electromagnetical actuation.
FIG. 6 shows a flow chart of a method according to an embodiment of the present invention. In a menu presentation step 602, a menu is presented on a display of a mobile communication apparatus, or at least as much of the menu that fits into the display. The menu can comprise text, icons, tabs or the like, and is provided by a processor of the mobile communication apparatus. In a feedback provision step 604, feedback is provided by tactile and/or visual feedback to a user, depending on angular position of the rotating input means and the position of certain items in the menu. In an input reception step 606, a selection of an item in the menu is performed by a user. The order in which the steps 602, 604, 606 should not be considered with any timing constraints. Contrary, an implementation of this embodiment would render that the steps 602, 604, 606 are performed in any order, different from time to time, and not seldom in parallel, as is the case for real-time operations.
FIG. 7 shows a flow chart of sub-steps of the feedback provision step 604 of FIG. 6. In a position determination step 702, one or more positions, or one or more areas corresponding to a range of positions, are determined to correspond to one or more certain items of a menu. The positions are expressed as angular positions of a wheelpad of a rotating input means. In a position marking step 704, the one or more positions, or one or more areas corresponding to a range of positions, are marked for feedback. Different positions can be marked in different ways, as is explained above with reference to FIGS. 3 and 4. The positions can also be marked for tactile feedback, such as increased rotational resistance or activated vibrating function. It is also possible to set sound markers.
