Description

User interfaces comprising a holographic image provider and associated methods
Technical Field
The present invention relates to the field of holograms, and in particular, but not limited to user interfaces comprising a holographic image provider and associated methods. Some specific embodiments of the present invention relate to a holographic image provider for portable electronic device, or the like.
In certain circumstances, such portable electronic apparatus/devices may or may not be hand-held in use (although they may be placed in a cradle in use). Such hand-portable electronic devices include so-called Personal Digital Assistants (PDAs).
Such portable electronic devices may provide one or more audio/text/video communication functions (e.g. telecommunication, videocommunication, and/or text transmission (Short Message Service (SMS)/ Multimedia Message Service (MMS)/emailing) functions), interactive/non-interactive viewing functions (e.g. web-browsing, TV/program viewing functions), music recording/playing functions (e.g. MP3 or other format and/or (FM/AM) radio broadcast recording/playing), downloading/sending of data functions, image capture function (e.g. using a (e.g. in-built) digital camera), and gaming functions.

Detailed description of the Figures Figure 1 shows a holographic image provider 100, provided on a layer 150, which in the present embodiment is a holographic film (e.g. a photographic film). It will be appreciated that in alternative embodiments the layer may be provided by other type of holographic layer, such as an etched layer, embossed layer or the like.
The image provider 100 comprises a first holographic image 110 and a second holographic image 120; the representative images of which are shown in Figure 1 to the side of the image provider 100. In the present embodiment, each holographic image 110, 120 is provided on the same layer of holographic film 150. Such an arrangement may be provided by exposing a photosensitive material, such as a photographic, or holographic film, twice in a holographic manner (e.g. by exposing a film to a reference beam and an object beam for one particular holographic image, and then exposing again to reference beam and an object beam for another particular holographic image). In alternative embodiments, further holographic images may be provided on the same holographic film layer.
The first holographic image 110 of the present embodiment is arranged to provide a holographic representation, or holographic image, of an e-message indicia 115. The second holographic image 120 is arranged to provide a holographic representation, or holographic image, of an arbitrary object 125. In the present embodiment both holographic images 110, 120 substantially overlie one another. In alternative embodiments however, this need not be the case. The holographic images 110, 120 may only partially overlie one another, or may be distinct (i.e. not overlie). In such an arrangement the holographic images 110, 120 may occupy different regions of the holographic film 150.
The image provider 100 in the present embodiment 100 is provided by a substantially square-like arrangement, and is thus provided with edge regions 130a, 130b, 130c, 13Od. Each edge region 130a-130d is angled by roughly 90 degrees from each adjacent edge region 130a-130d.
In the present embodiment, the first holographic image 110 is arranged to be edge-lit by a first reconstruction beam 140a at a first edge region 130a of the image provider 100, such that, when illuminated, the holographic image of e-message 115 is apparent to a viewer. The second holographic image 120 is arranged to be edge-lit by a second reconstruction beam 140b at a second edge region 130b of the image provider 100, such that, when illuminated, the holographic image of the arbitrary object 125 is apparent to a viewer. Therefore, in the present embodiment the first holographic image 110 is arranged to be edge-lit by a reconstruction beam 140a angle that differs by θ to the reconstruction beam 140b angle required to edge-light the second holographic image 120, which in the present embodiment is 90 degrees.
It will readily be appreciated by the skilled reader that the image provider 100 may be arranged such that both the first and second holographic images 110, 120 are arranged to be edge-lit by reconstruction beams at the same edge region 13Oe. However, in such an arrangement the angle of each reconstruction beam 140a, 140b still differs. Figure 1 b shows such an alternative arrangement.
In use, the first holographic image 1 10 can be illuminated using the first reconstruction beam 140a. As a result, a holographic image of an e-message would be apparent to a viewer. Due to the fact the that the angle of the reconstruction beam required to illuminate the second holographic image 120 was 90 degrees displaced, the second holographic image 120 would substantially not illuminate by the first reconstruction beam 140a. By removing the first reconstruction beam 140a and applying the second reconstruction beam 140b, the second holographic image 120 is illuminated. As a result, a holographic image of an arbitrary object 125 is apparent to a viewer. At that time, and due to the fact the that the angle of the reconstruction beam required to illuminate the second holographic image 120 is 90 degrees displaced, the first holographic image 110 would substantially not illuminate by the second reconstruction beam 140b. By selectively providing each reconstruction beam 140a, 140b, a viewer would observe an animation effect (e.g. a changing display) between the two holographic images 110, 120.
Figure 2a shows side view of a further image provider 200, comprising a substrate 260, which is transparent. In this arrangement, the image provider 200 comprises four holographic films 250a-250d. The holographic films 250a-250d each comprise a single holographic image 270a-270d. In alternative embodiments, each holographic film 250a-250d may comprise more than one holographic image 270a-270d (e.g. similar to that shown in Figure 1 ).
The substrate 260 is arranged to allow four reconstruction beams 240a-240d of particular angles to be coupled to the holographic images 270a-270d for edge-lit illumination. In the present embodiment each successive holographic image 270a-270d is arranged to be edge- lit by a reconstruction beam differing by θ from the reconstruction beam of a previous holographic image 270a-270d, which in the present embodiment is 45 degrees. It will readily be appreciated that in alternative embodiments each subsequent reconstruction beam need not differ by the same angle from the previous reconstruction beam. In alternative embodiments the angle θ may vary between the required reconstruction beams.
The substrate 260 is further arranged to mechanically support the four holographic films 250a-250d. In the present embodiment, the substrate 260 is provided by a glass material.
However, the skilled reader will appreciate that in alternative embodiments, other materials may be used, such as transparent plastics, and the like. The holographic films 250a-250d are placed directly adjacent one another (e.g. so as to be overlying), and then placed on the substrate 260. In alternative embodiments, each holographic film 250a-250d may only partially overlay one another, or may occupy distinct regions on the substrate 260.
Figure 2b shows a plan view of the image provider 200 of the present embodiment. In this Figure each holographic image 270a-270d is shown. In the present embodiment the plan view is the intended viewing angle of the image provider 200. Each holographic image 270a- 27Od is provided by the same arbitrary shape. However, the image provider 200 is arranged such that the viewed holographic images 270a-270d differs in position when viewed from the viewing angle. In the present embodiment each holographic image 270a-270b at least partially overlaps with another holographic image 270a-270d when viewed from the viewing angle.
It will readily be appreciated by the skilled reader that the image provider 200, may comprise more than one substrate 260 for each holographic film (e.g. holographic film/image, etc.), such as a separate holographic film 250 per substrate 260, or the like. Figure 2c shows such an arrangement. Similarly it will be appreciated that in such an arrangement, the reconstruction properties of each holographic image may be the same (e.g. the reconstruction beams for each holographic image are substantially the same, such as angle and/or wavelength), but the image provider 200 is configured such that a particular beam coupled with a particular substrate illuminates substantially only the holographic image provided in association with that substrate (e.g. by using a totally internally reflected beam to communicate the beam to a particular holographic image, or the like).
Similarly, while in this arrangement each of the holographic images 270a-270d at least partially overlie another holographic image (e.g. 270b partially overlies 270a) when viewed from the viewing angle, in alternative arrangements this need not be the case. Figure 2d shows an exemplary arrangement of the image provider 200 in which only some of the holographic images appear to overlie. In alternative arrangements still, none of the holographic images 270a-270d may overlie one another.
Figure 2e shows a further arrangement in which each of the holographic images 270a-270d differs in size. In this arrangement, the image provider is arranged such that, when illuminated, the holographic image appears to simulate a breathing effect (e.g. a shape getting larger and smaller). Figures 2f and 2g show an arrangement in which a face is able to nod, and/or shake.
Figure 3a shows an apparatus for providing holographic images 700, comprising the holographic image provider of Figure 2. Here, the apparatus 700 further comprises illuminators 780 arranged to edge-light each holographic image 270a-270d of the image provider 200. In this embodiment, the illuminators 780 are provided by laser diodes. The illuminators 780 are controlled by a controller 790. The controller is arranged to selectively control the illuminators 780 in a particular sequence.
In use, a reconstruction beam from each illuminator 780 may be selectively controlled by the controller 790, so as to edge-light each particular holographic image 270a-270d. Due to the fact that the angle of reconstruction beam 240a-240d required to illuminate a particular holographic image 270a-270d differs by at least 45 degrees from the reconstruction angle of a reconstruction beam of a different holographic image 270a-270d, each other holographic image 270a-270d is substantially not illuminated by a reconstruction beam other than that intended. By selectively illuminating each holographic image 270a-270d in sequence, a viewer, viewing from the viewing angle observes an animation effect of a holographic image 270a-270d, which appears to move across the plan view of the image provider 200.
It will readily be appreciated that while in this embodiment, multiple static illuminators 780 are provided, in other embodiments this need not be the case. In alternative embodiments, at least one illuminator 780 may be provided as a dynamic illuminator. That is, that the angle of the illuminator may be controlled by the controller 790 so as to provide for the different reconstruction angles. In such an arrangement the light output of the illuminator 780 may be directionally altered, and/or the position of the illuminator 780 may be altered.
Figure 3b shows a further exemplary arrangement of an apparatus for providing holographic images in which one illuminator 785 is arranged as a dynamic illuminator. In this arrangement, the illuminator 785 is positionally controlled by the controller 790 so as to be able to direct light to enter the image provider 200 over a length, L, of an edge region of the image provider. In some embodiments, the directionality of the light (or reconstruction beam) emitted from the illuminator 785 is not entirely uniform (i.e. not entirely collimated). In some embodiments, when the dynamic illuminator 785 is provided by an LED, or the like, the illuminator 785 is provided with a small divergence angle (e.g. a viewing angle of a few degrees (e.g. 1 , 3, 5, 10)). In other embodiment the viewing angle may be larger, such as 100, 120, 140 degrees, or the illuminator may be a point source.
Movement of the illuminator 785 in such arrangements provides a similar effect to a change in viewing angle for a user. In this arrangement a holographic image 270 also appears to have an animation effect. A gradual change of the location of the illuminator 785 provides for a gradual change of the holographic image (e.g. when the illuminator is illuminating that holographic image). In alternative embodiments, multiple dynamic/static illuminators 785 may be provided along a particular length (e.g. of an edge region of the image provider). In such arrangements, each illuminator 785 may be selectively controllable to provide the (additional) animation effect.
Similarly, it will readily be appreciated that the in some arrangements the illuminators 785 may remain stationary, and the image provider 200 may be moved, or alternatively a combination of movement of the illuminators 785 and the image provider 200 may be provided.
It will be readily appreciated that one, some or all the illuminators may be provided as such dynamic illuminators 785. In some embodiments, the dynamic illuminators may be arranged to provide for alteration of the angle of reconstruction beam (e.g. changing the directional output of the illuminator), and/or alternation of the location of dynamic illuminator. It will also readily be appreciated that the altered direction/location may be provided by two or more different static/dynamic illuminators, which may be selectively illuminated.
Figure 4a shows a side view of a further image provider 300, similar to that of Figure 2. Figure 4b shows the image provider 300 from an angled perspective. In this arrangement the image provider 300 is provided with three holographic images 370a-370c, each provided on a separate holographic film 350a-350c. Here, the image provider 300 further comprises a substrate 360, on which the holographic films 350a-350c are supported. In this exemplary embodiment each holographic image 370a-370c substantially overlies each other holographic image 370a-370c, when viewed from a viewing perspective (e.g. unlike the arrangement in Figure 2, in which each holographic image 270a-270d differs in position when viewed). In this embodiment, the holographic images 370a-370c are arranged to be illuminated by reconstruction beams from a single angle.
In this embodiment, the holographic images 370a-370c are arranged to be illuminated by reconstruction beams of differing wavelengths. Each of the three holographic images 370a- 370c are arranged to be illuminated by a reconstruction beam 391a-391 c of a different colour (i.e. wavelength). In the present embodiment, each is arranged to be illuminated by a reconstruction beam of red yellow or green. It will readily be appreciated that in alternative embodiment other colours may be used.
In use, each of the three holographic images 370a-370b may be illuminated by using illuminators/controller, similar to those shown in Figure 3. Due to the fact that the wavelength of the reconstruction beams for each holographic image 370a-370c is different, only that holographic image for that particular wavelength will be illuminated. In a similar manner to that described previously, the controller may control the illuminators to provide selection of a particular holographic image and/or an animation effect. While only three holographic images 370a-370b are described here, it will readily be appreciated that in alternative embodiments, further holographic images may be provided, each arranged to be illuminated by a reconstruction beam of a differing wavelength.
Figure 4c shows a side view of a further embodiment of the image provider 300. Figure 4d shows the image provider 300 from an angled perspective. In this arrangement the image provider 300 is provided with twelve holographic images 370a-370l, each provided on a separate holographic film 350a-350l. Again, the image provider 300 comprises the substrate 360, on which the holographic films 350a-350l are supported. Each holographic image 370a- 370I substantially overlies each other holographic image, when viewed from a viewing perspective. In this embodiment, the holographic images 370a-370l are additionally arranged to be illuminated by reconstruction beams from four angles, each displaced by 45 degrees.
In this embodiment, those holographic images 370a-370c; 370d-370f; 370g-370i; 370J-370I that are arranged to be illuminated by reconstruction beams at the same angle, are arranged to be illuminated by reconstruction beams of differing wavelengths, in a similar manner as described above. Here, four sets each comprise three holographic images 370a-370l that are arranged to be edge-lit by reconstruction beams of substantially the same angle. Each of the three holographic images 370a-370c; 370d-370f; 370g-370i; 370J-370I within a set are arranged to be illuminated by a reconstruction beam 391 a-391 c; 392a-392c; 393a-393c;
394a-394c of a different colour (i.e. wavelength). In the present embodiment, each is arranged to be illuminated by a reconstruction beam of red yellow or green. It will readily be appreciated that in alternative embodiment other colours may be used.
Figure 4e shows four image providers 300 in which the holographic images 370a-370l provide Arabic numbers. In this arrangement the four image providers 300 are arranged as a digital clock 400. In use, each specific holographic image corresponding to a particular Arabic numeral may be illuminated using a particular reconstruction beam of a particular angle and wavelength. Due to the fact that the angle of the reconstruction beam differs from the angle of the reconstruction beams in differing sets, those holographic images in other sets are substantially not illuminated. Due to the fact that the wavelength of the reconstruction beams for each holographic image 370a-370l within a set are different, only that holographic image for that particular wavelength will be illuminated.
It will readily be appreciated that by providing an apparatus/clock 400 with illuminators 780 and a controller 790, similar to that of shown in Figure 3, and selectively controlling the illumination of each holographic image 370a-370l, a viewer, viewing from viewing angle, will see a changing holographic digital clock display.
Figure 5a shows a further exemplary embodiment of the present invention in plan view, while Figure 5b shows a slightly angled perspective. In this embodiment there is provided an analogue clock arrangement 600, comprising a plurality of image providers 500, and an plurality of LEDs 610 indicating the stations of the clock (i.e. 12, 1 , 2, 3, 4, etc.) . Here, the there is provided twelve image providers 500 for indicating the minute hand, and twelve image providers 500 for indicating the hour hand. Each image provider 500 is arranged between the stations of the clock. That is, two image providers 500 between 1 and 2 (i.e. a minute hand image provider 500, and an hour hand image provider 500), two image providers 500 between 2 and 3, two image providers 500 between 3 and 4, etc.
In this arrangement, each image provider 500 comprises six holographic images, arranged to be illuminated by reconstruction beams from two directions and of three differing wavelengths. Each holographic image is arranged to be illuminated so as to indicate a particular position between the particular stations of the clock. In use, each image provider 500 may be illuminated by particular edge-lit reconstruction beams of particular wavelength so as to provide a minute/hour hand indicating the particular time. Figure 6a shows an electronic apparatus 1000, which in the present embodiment is a portable electronic apparatus, such as a mobile phone (for the sake of clarity those features of a mobile phone have been omitted, such as user input interface, memory, processor, etc.), comprising a user interface 1010 comprising an image provider 1200, two illuminators 1030, and a controller 1020. While in this embodiment only two illuminators 1030 are provided, it will be readily appreciated by the skilled reader that the number of such illuminators 1030 may vary depending upon the number of holographic images to be illuminated. Here, holographic images of the image provider a selectively viewable as user interface icons 1015.
Figure 6b shows the user interface 1010 in which two holographic images are viewable as user interface icons 1015. In alternative embodiments, only one holographic image may be provided (i.e. one user interface icon). Alternatively, any number may be provided, such as 1 , 5, 10, 20, 50 or any number therebetween. In this example, the user interface icons 1015 are virtual icons, such as virtual menu icons, virtual buttons, virtual keys (e.g. keys for a virtual keypad), or the like. It will readily be appreciated that in alternative embodiments the user interface icons may provide any of the above described arrangements, (e.g. animation, digital clock, etc.), which in some embodiments may be used as screen saver icons, or the like.
The controller 1020 is configured, in use, to control the illuminators 1030 so as to provide illumination of holographic images on the user interface 1010, so as to provide the user interface icons 1015. The user interface icons 1015 may be provided at the request of a user (e.g. a screen tap, etc.), or in response to some other process on the device (e.g. receiving an incoming call, sending a message, processing GSM data).
Figure 6c shows a further arrangement in which the user interface 1010 comprises two display icons 1300, in addition to a holographic image as a virtual icon/virtual menu icon 1015, and one associated illuminator 1030. In this arrangement each display icon 1300 is provided by the user interface 1010. In this embodiment, the user interface 1010 is provided by a back-lit display, such as LCD display. For example, the holographic image is provided in front of/behind/as part of the LCD display (e.g. a transparent LCD display) so as to provide for a virtual icon, in addition to those features of the display. That is to say that the user interface 1010 operates to provide user interface icons, as well as providing non-holographic display functions of such apparatus 1000. In this regard the display/holographic image provider may be considered as a multiplexed (active) display. In alternative embodiments the display may be an OLED display, or the like.
In the present arrangement, the illuminator 1030 is positioned such that the directionality of the reconstruction beam (i.e. angle of reconstruction beam) is substantially opposing that of the most likely directional ambient light when the apparatus 1000 is in use (e.g. noise light from daylight/indoor lighting from an above angle). In the arrangement when the apparatus 1000 is a mobile telephone, the skilled reader will readily appreciate that when the display is being viewed, that daylight/indoor lighting is likely to come from a direction above the phone.
The controller 1020 is configured to control the LCD display of the user interface 1010 (e.g. the display icons), as well as control the illumination of the virtual icon 1015. In this arrangement the controller 1020 is provided by the processor/memory of the apparatus 1000, although in alternative embodiments this need not be the case.
In use, the controller 1020 is able to provide for an animation effect between the display icons 1300 and the user interface icon 1015 by selective illumination. In addition, the controller 1030 is able to provide that the region of the LCD display that is viewed, when the user interface icon is illuminated, is of reduced illumination (i.e. that the user interface icon 1015 is more visually prominent when illuminated). Similarly, due to the angle of reconstruction beam required by the user interface icon 1015, the noise light, acting on the holographic image in use, does not act to substantially illuminate the user interface icon (i.e. when the user interface icon is not illuminated by the controller 1030, the user interface 1010 is configured to reduce ghosting of the holographic image, particularly in use).
A skilled reader will readily appreciate that while only two display icons 1300 and a single user interface icon 1015 have been described, in alternative embodiment this need not be the case, and any number of display icons 1300 /user interface icons 1015 may be provided.
In some embodiments only one user interface icon 1015 may be provided, without any associated display icons 1300. In this arrangement the user interface icon 1015 may act to provide a virtual icon, in a similar manner as described above.
Figure 6d shows a further arrangement in which the apparatus 1000 further comprises sensors 1017, which in the present embodiment are proximity sensors. The sensors 1017 are in communication with a processor 1018 and memory 1019, in a known manner, such that the user may select the virtual icon 1015, so as to provide that particular operation or function on the electronic apparatus 1000. It will readily be appreciated that in alternative embodiments, a touchcreen, or the like may be provided. In additional alternative embodiments, the virtual icons (e.g. virtual menu icons) may be provided in addition to display icons, as will be readily appreciated.
Figure 7 shows an electronic apparatus 1100, similar to that described in relation to Figure 6. Here, the apparatus 1 100 comprises a display region 1 110, a controller 1120, and illuminators 1130. In the present embodiment, the display region 1110 comprises a receiving portion 1115, arranged to allow attachment and detachment of a user interface 1250. In use, a user may attach/detach differing user interfaces 1250 so as to provide for differing user interface icons (e.g. differing animation effects). In the present embodiment, the apparatus 1 100 is arranged such that the illuminators 1 130 are not activated when the user interface 1250 is removed from the apparatus 1100.
In alternative embodiments, the controller 1 120 may not be provided by the apparatus 1100 and may be provided with the attachable/detachable user interface 1250. In such arrangement the controller 1 120 may be arranged to control, via a connection to the apparatus 1100, the illuminators 1130, so as to provide for selectively viewable user interface icons, for example virtual icons, Screensaver icons (e.g. animation effect, Nokia® handshake, etc.) of that particular user interface 1250. In alternative embodiments, the attachable/detachable user interface 1250 may be provided with instruction to run a controller 1120 on the apparatus 1 100. In such an arrangement, control instructions, or software or the like, may be transferred to the apparatus 1100 via a connection, such as a smart chip and reader arrangement, WiFi, Bluetooth, etc. This may occur once the user interface has been attached to the apparatus 1100. In further embodiments still, the attachable/detachable user interface 1250 may additionally/alternatively comprise the illuminators 1 130. A skilled reader would readily be able to implement such alternative arrangements. The attachable/detachable user interface 1250 may comprise a display (e.g. in a similar manner to Figure 6c), or the user interface 1250/apparatus may be arranged such that the user interface 1250 is attachable/detachable with a display of the apparatus 1 100.
It will be readily appreciated that the above embodiments are exemplarily only, and that any of the features of one embodiment may be implemented in relation to another. Figure 8 shows a flow chart 800 of a method of controlling a user interface of a portable electronic apparatus, the user interface providing holographic images for use as user interface icons of the portable apparatus, comprising: providing 810 a holographic image provider comprising a plurality of holographic images. Secondly, configuring 820 the holographic images in such a way that when selectively edge-lit by reconstruction beams at differing respective particular angles there is provided for selective holographic images viewable as user interface icons. Thirdly, edge-lighting 830 the holographic image provider to provide for a particular sequence of the user interface icons to be illuminated.

It will be appreciated to the skilled reader that the user interface/device/apparatus described above may be provided by a user interface/device/apparatus arranged such that it becomes configured to carry out the desired operations only when enabled, e.g. switched on, or the like. In such cases, it may not necessarily have the appropriate software loaded into the active memory in the non-enabled (e.g. switched off state) and only load the appropriate software in the enabled (e.g. on state).
It will be appreciated that the aforementioned user interface/image provider/apparatus/device may have other functions in addition to the mentioned functions, and that these functions may be performed by the same user interface/image provider/apparatus/device.
