Definitions

• This invention relates to a digital display, and more particularly, to a digital display for providing a human interface in electronic apparatus, such as a mobile telephone, domestic appliance or the like, to display a plurality of items of data for review and/or selection by a user.
• electronic apparatus including a digital display means for displaying a plurality of data items thereon, the apparatus including mechanical input means for scrolling through, highlighting and/or selecting one or more of said data items, means for producing and displaying a graphical representation of one or more components or elements, said graphical representation being representative of at least a portion of said mechanical input means, or an imaginary portion, element or component thereof, and means for animating said graphical representation in accordance with mechanical operation of said input means so as to at least provide an illusion of connectivity between said input means and said graphical representation.
• electronic apparatus including a digital display means for displaying a plurality of data items thereon, the apparatus including mechanical input means for scrolling through, highlighting and/or selecting one or more of said data items, at least a portion of said mechanical means being hidden or obscured from view externally of said apparatus, said hidden or obscured portion of said mechanical means, and/or its mechanical operation when in use, being graphically represented and/or displayed on said display means.
• the underlying concept of the present invention is thus a literal and animated graphical link between a physical interface and the on-screen graphic being controlled thereby.
• This provides two main benefits over the prior art, namely that it makes menu systems on (particularly) small screen devices more intuitive with more visual feedback, and that it creates a stronger perceived link between external means and on-screen information.
• the present invention concerns the graphical representation on a display screen of an input means.
• Some kind of visual representation of the mechanical input means is provided on the screen, which representation is animated to mimic or otherwise represent its mechanical behaviour during operation, giving the impression that the mechanical means and the animated graphic are in fact linked.
• the mechanical input means are preferably analogue input means, such as one or more rotating wheels (having their axis of rotation movement in line with and/or perpendicular to and/or at any other angle relative to the display screen), one or more sliders (with movement in any direction relative to the screen plane, linear or otherwise), optical, field or other proximity sensing (with such sensing being theoretically possible in any direction relative to the screen plane), tilt or inclination sensing (again in any direction relative to the screen), etc.
• analogue input means such as one or more rotating wheels (having their axis of rotation movement in line with and/or perpendicular to and/or at any other angle relative to the display screen), one or more sliders (with movement in any direction relative to the screen plane, linear or otherwise), optical, field or other proximity sensing (with such sensing being theoretically possible in any direction relative to the screen plane), tilt or inclination sensing (again in any direction relative to the screen), etc.
• the input means may sense analogue movement, it may achieve this in
• the animated screen graphic may be a representation of just the invisible or obscured portion of the input means but it may in addition include a representation of all or part of the visible portion(s) thereof.
• the graphical representation of the input means need not necessarily be true representation of the input means, but may include or omit features thereof, while still giving the impression of a mechanical/graphical link between the two.
• the animated screen graphic may include additional graphical elements on or in association with the graphical representation of the input means to give the impression of a link to other virtual elements or components.
• a single electronic device may include one or more digital display means each including one or more input means and graphical representations thereof.
• the mechanical input means may be geographically offset from the plane of the display screen such that any visible portion of the input means and its corresponding graphical representation appear to be lined up at the normal angle of operation of the apparatus.
• the graphical representation of the input means displayed on the screen may include perspective and three-dimensional features so as to improve the realism of the graphical representation at least when viewed from the normal or usual angle of operation of the apparatus. Such perspective or three dimensional features may be exaggerated to enhance the illusion of realism and/or to contribute to the aesthetic appearance of the graphic environment.
• the graphical representation of the input means as displayed on the screen is beneficially of a similar size and scale to the corresponding portion of the input means, so as to maximise the realism of the representation, a different scale or manner of operation of the input means may be provided according to requirements.
• the graphical representation might be representative of its operation in the form of an action which is typical of the action or parameter being sensed.
• an animated element such as a ball or the like may roll around the screen in accordance with the tilting of the apparatus.
• the location on the screen of the 'virtual' ball is preferably such that it indicates the data item which is currently highlighted for selection or review.
• the graphical representation of its operation may, for example, comprise a 'virtual' shadow which appears to pass over the screen as a user passes their hand thereover. Again, the location of the shadow on the screen may be indicative of the data item which is currently highlighted for selection or review.
• the input means may comprise one or more of a plurality of different types.
• the input means may comprise one or more sliders (linear, curved, complex curve movement, etc), or rotary sensors, for example.
• Such sliders or rotary sensors may use:
• strain measuring element changes electrical resistance
• Light level sensing (light is reflected or varied by movement of slider, this is sensed and converted into either power or resistive electrical quantity).
• Incremental electrical contacts (a plurality of contacts/electrical switches along movement axis).
• Magnetic switching magnetic elements on or near sliding portion can be sensed to give position data, reed switches or hall effect sensing).
• Magnetic hynamo effect moving magnetic in relation to coil to create quantity of electrical power which can be measured.
• Piezoelectric effect pressure upon piezoelectric crystals creates measurable electrical charge which can be measured) (a few can be used to simulate multiple cam effect described above).
• Capacitance proximity sensing (measuring position of obj ect by how much generated electric field is leaked through it, can sense proximity and position of human body parts)(also similar is using a leaking static charge).
• the above can be mixed in many ways and can have more than one axis of sensing, eg as in the case of a joystick.
• options 1, 2, 4 and 5 above might, in many cases, be considered to be most advantageous (in view of the fact that they do not generally increase the power consumption of the overall apparatus, although option 6 is also considered to be advantageous as it is very durable and offers great accuracy.
• the apparatus beneficially includes computation means for determining the true position of the input means and equating such positional information to means for altering the graphical representation thereof on the display screen.
• Such computational means may comprise, for example:
• An electronic/electrical process can interface input means to display such that the process lies in the behaviour of the components rather than a software element. This process could be digital or analogue.
• An electronic "processor” can interface input means to display which uses software or "data” to incrementally process the information.
• This processor can be dedicated to the described function or in addition “process” other calculations required for the operation of the device as a whole.
• This processor could generate the displayed graphics mathematically or access pre- made graphics in digital formation from a data storage area or device (memory), and of course, a mixture of these processes can be used.
• Programmable electronics although primarily digital are available now with analogue/digital and digital/analogue signal converters. These often dedicated functions could be used if the sensing means has an analogue electrical output. Some displays too offer effects from an analogue input. Additional (possible) computation/interface means:
• Analogue or digital electronic elements/components may be used in addition to primary computation means to "clean” or alter data from input means such that it is in a format more readily “understood” by computation means.
• Typical functions would be “de-bouncing” (getting rid of contact noise) contact based sensing means, analogue to digital converts (to turn analogue data from input means into a digital form for a microprocessor/controller).
• This element may have its own processes to create electrical signals suitable for the display. This element may also change the voltage or current aspects of the incoming electrical data such that it is at a level suitable for display device.
• Pressing input means might also activate a back light or make a telephone call etc. This process could also be reversed in the sense that, for example, an incoming call could make graphic shake a little bit or re-activate after a sleep period.
• the sensing and display means could be designed/electrically connected such that no computation means is required.
• the sensing and display means could directly drive pixels/shaped elements on a display.
• Other functions or a computational means could be connected to the interconnection between input means and display to further process the position information, but actually have no effect on the function of the idea.
• the display means may be any one or more of the following: 1. Liquid crystal display. Uses uniform or shaped areas that generally appear black when electrically activated. Can use mask/filter effects to create illusion of colour. Can have reflective elements so that graphic is observed against a backdrop of reflected light. Can have a back light of some form. could be predominantly or partially transparent. Active areas alter level of this transparency.
• Plurality of light emitting diodes (any shape). could be in a uniform matrix but not necessarily. Can use a range of colours. Shape of individual LED may contribute part or a whole section of displayed graphic.
• Vacuum display A sealed transparent chamber which uses electrical reaction with contained gas to create light. Emitters of electrical charge can be shaped such that parts or whole graphics may be displayed.
• Electro-luminescent segments shaped to form part or whole of portion of graphic. Variety of colours possible. Often used as a back light for LCD screens.
• any of the above display means could be mixed, and/or filtered, reflected or optically altered in any other way such that the result is still a representation of the mechanical input means.
• the present invention can be used in any electronic apparatus having a digital display screen, including washing machines, central heating controls, ovens, fridges, and other domestic appliances, electronic toys, game consoles, stereos (home/car/portable), television/stereo remote controls, and similar entertainment based appliances, clocks/watches, mobile/stationary telephones, PDA's, lap tops, etc.
• the present invention substantially increases the user-friendliness of any electronic apparatus having a digital display screen in the sense that it gives a conceptual and visual correlation between the operation of the user-controlled input means and the data items displayed on the screen.

• the input means should be correctly placed in terms of the final viewing angle, but not necessarily in line with the actual means for producing visual information.
• the graphical representation of the input means may be rendered on a plurality of displays 100, 110, which combine to create a final graphic image. Graphics not related to the input means representation may also be presented on one, some or all of the displays which combine in this manner.
• the graphical representation of the input means may alter visually to link more closely to other graphics or data on different virtual pages displayed on the screen, ie the default first page may be very simple, the main menu page may have a simple simulated mechanical link to the input means, and again page may have a representation graphic with, for example, steering wheel attributes, or the like.
• the graphical representation of the input means may disappear partially or entirely if the device as a whole goes into a power off or standby mode, as illustrated by Figure 36 of the drawings. It may also be arranged to partially or entirely disappear, distort etc. to make display space for other displayed information, for example, long SMS texts, WAP pictures, etc.
• the graphical representation of the input means may distort or move in a dissimilar manner to the input means to create, for example, entertaining animation in certain cases, such as switching the power on and/or off, virtual page transitions, etc. This may also occur at predetermined intervals of time for entertainment purposes and the like.
• Figure 38 illustrates the case whereby data items are linked to and highlighted according to the position of a pulley-like graphic on the screen, the rotary operation of which appears to follow the corresponding movement of the rotary input means.
• Figure 39 illustrates an example of the present invention when applied to a wristwatch or the like. Mechanical rotary or linear movement of the watch face results in corresponding movement of the graphical display thereon.
• Figure 40 illustrates an example of the present invention when applied to a washing machine or similar appliance. As shown mechanical rotary movement of the dial results in a corresponding graphical indication of the selected parameter (such as, in this case) wash temperature.
• the selected parameter such as, in this case
