Abstract

A self-orienting display senses the characteristics of an object and automatically rotates and reformats a display image in accordance with those characteristics. In one embodiment, the object is the display device, such as a hand held device, that provides the display image. As the display device is rotated, the display image is automatically oriented to either a landscape orientation or a portrait orientation. Characteristics may be sensed by mechanical sensors, electrical sensors, optical sensors, acoustic sensors, gyroscopic sensors, or a combination thereof. Sensors may be positioned on the display device, a person, or a combination thereof. The display images may include graphic display images, textual display images, videos display images, and functional control buttons (e.g., functional displayed representations of control buttons such as play, rewind, stop, scroll). The self-orienting display may also include an authenticator that authenticates a user.

Description

FIELD OF THE INVENTION
• The present invention generally relates to displays and more specifically relates to systems and methods that automatically orient displays.[0001]
BACKGROUND OF THE INVENTION
• Display devices are becoming smaller and more portable. Display devices such as flat liquid crystal displays (LCDs) and plasma displays are relative thin and light weight. These light weight, smaller displays are more easily maneuvered than many of the bulkier cathode ray tube (CRT) displays. Due to the increased maneuverability of these displays, viewers are more likely to turn or rotate the display. This is also applicable to the plethora of available hand held display devices such as personnel digital assistants (PDAs), cell phones, and games, just to name a few. As the cost of these display devices continues to decrease, and the increasing number of smart devices which incorporate these displays increases, more and more users will be using these products to accommodate a variety of needs.[0002]
• However, a problem with current display devices is that the display image becomes difficult to read/see when the display device is turned or rotated. For example, as a hand held PDA is rotated 90°, the display image appears tilted and can be difficult to interpret, or a viewer watching television may decide to lie down, which also makes the display image on the television appear tilted. Furthermore, some multipurpose devices are better suited to display specific display types in specific formats, such as text in traditional portrait orientation and video in landscape orientation.[0003]
• A display device which overcomes these problems is desired.[0004]
SUMMARY OF THE INVENTION
• A method for orienting a display image includes sensing at least one characteristic of an object and determining the orientation of the object from at least one of the sensed characteristic(s). An image display is oriented relative to the determined orientation of the object. A system for implementing this method includes a sensor portion and a display processor. The sensor portion senses at least one characteristic of an object and provides a sensor signal indicative of the characteristic(s). The display processor receives the sensor signal and determines the orientation of the object from the sensor signal. The display processor also orients a display image relative to the determined orientation of the object.[0005]

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
• A self-orienting display in accordance with the present invention senses the orientation of an object and automatically orients a display image in accordance with the orientation of that object. As described herein, self-orienting includes automatically rotating, along any number of axes, and formatting. An exemplary embodiment of this self-orienting display comprises a monitor that automatically orients the display image provided by the monitor to either a landscape orientation or a portrait orientation in response to the orientation of the monitor. However, this is just one of many envisioned embodiments. For example, the display image may be rotated in response to an audio command, such as “rotate”, or the display image may be rotated in response to depression of a switch on the display device. Various embodiments of the self-orienting display include various embodiments of the object, the sensors, the format of the display image, and functions performed by the self-orienting display. For example, objects may include the display device that provides the display image, a person viewing the display image, an object within visual and/or acoustic range of the self-orienting display, or a combination thereof. The display device may be any appropriate device having the capability to provide a display image, such as a monitor, a hand held device, a personal digital assistant (PDA), a cellular telephone having a display, a game device having a display, or a portable computer, for example. Various embodiments of sensors include mechanical sensors, electrical sensors, optical sensors, acoustic sensors, gyroscopic sensors, or a combination thereof. Example sensors include mercury switches, infrared detectors, motion detectors, ultrasonic detectors, cameras, and microphones. Furthermore, sensors may be positioned on the display device, a person, or a combination thereof (e.g., mercury switches attached to the display device and gyroscopic sensor attached to a headset of a viewer of the display image). Various embodiments of the display image include graphic display images, textual display images, videos display images, and functional control buttons (e.g., functional displayed representations of control buttons such as play, rewind, stop, scroll), for example. A more detailed description of these various embodiments is provided below.[0019]
• FIG. 1 is an illustration of a self-[0020]orienting display100 comprising adisplay device12, adisplay image14, asensor16, andoptional control buttons18. The self-orienting display12 may be in the form of any appropriate display device capable of providing thedisplay image14. Examples ofappropriate display devices12 include cathode ray tube (CRT) displays, plasma displays, light emitting diode (LED) displays, flat panel displays, projection displays, wireless devices (e.g., cellular devices including telephones, personal digital assistants (PDAs), portable computers; and devices communicating via an optical link, such as an infrared link), hand held devices (e.g., hand held games or game controllers), televisions, radios, or alarm clocks, just to name a few.
• The[0021]sensor16 may comprise any type of sensor capable of sensing the orientation of thedisplay device12 and/or another object (e.g., a person viewing the display image14). Examples of appropriate sensors include mechanical sensors, electrical sensors, optical sensors, acoustic sensors, gyroscopic sensors, or a combination thereof. Some specific types ofsensors16 include mercury switches, infrared detectors, motion detectors, ultrasonic detectors, cameras, and microphones, or a combination thereof. Note some types of sensors fall into more than one category. For example, a mercury switch may be considered a mechanical sensor and an electrical sensor, or an ultrasonic sensor may be considered an acoustic sensor and an electrical sensor. Thesensor16 may include a single sensor or a plurality of sensors. Thesensor16 may be positioned at various locations on thedisplay device12 or may be positioned at a single location. For example,sensors16 may be placed at the corners of thedisplay device12. Furthermore,sensors16 may be positioned on the display device, a person, or a combination thereof.
• The[0022]display image14 may be in the form of a graphic display image, a textual display image, a video display image, and afunctional control button18, or a combination thereof. Thedisplay image14 may comprise display image portions, such asdisplay image portions14aand14b. As depicted in FIG. 1, a graphic/video display type is provided by thedisplay image portion14aand a text display type is provided by thedisplay image portion14b. For example, thedisplay image portion14amay depict a video and thedisplay image portion14bmay depict email headers/text. It is to be understood that this depiction is exemplary, and not intended to be limited thereto. For example, thedisplay image14 may not be partitioned into portions, thedisplay image14 may be portioned into a plurality of portions, the display image portions may overlap, the display image portions may provide any combination of display types, or a combination thereof. In some embodiments of the self-orientating display, the control buttons are implemented as display image portions (described in more detail below). It is to be understood, therefore, that reference to displayimage14,display image portion14a, and/ordisplay image portion14b, may also be appropriately interpreted to refer to thecontrol buttons18 when implemented as display portions. For example, a description of rotation and formatting techniques to be applied to thedisplay image14 also applies to thecontrol buttons18 implemented as display portions.
• The[0023]control buttons18 may comprise any appropriate type of control device capable of controlling functions related to thedisplay image14 and/or thedisplay device12. In one embodiment, thecontrol buttons18 comprise liquid crystal display (LCD) buttons with a protective overlay (e.g., a touch switch). In another embodiment, eachcontrol button18 comprises an array of light emitting diodes (LEDs). In yet another embodiment, eachcontrol button18 comprises a thin disc or the like, formed in a desired shape (e.g., triangle) contained within the liquid. In still another embodiment, thecontrol buttons18 are weighted such that a portion of each button is always oriented towards the greatest gravitation force. Thecontrol buttons18 control various aspects of thedisplay image14 and/or thedisplay device12. Functions controlled by thecontrol buttons18 may include, for example, playback, pause, stop, rewind, enable/disable back lighting, or a combination thereof. Furthermore, thecontrol buttons18 may include an orientation button that, when activated, orients thedisplay image14. For example, one of thecontrol buttons18 may switch thedisplay image14 between landscape orientation and portrait orientation each time the button is depressed/touched. In another example, the orientation control button may rotate thedisplay image14 a predetermined number of degrees each time it is depressed/touched. Thecontrol buttons18 are optional. Thus, various embodiments of the self-orienting display in accordance with the present invention may or may not comprise control buttons.
• FIG. 2A is an illustration of a rotated display device not possessing a self-orienting capability. FIG. 2B is an illustration of rotated self-orienting[0024]display device12 showing the orienteddisplay image portions14a,14b, andcontrol buttons18. The display devices shown in FIG. 2A and FIG. 2B are rotated 90 degrees with respect to thedisplay device12 shown in FIG. 1. Comparing FIG. 2A with FIG. 2B, thedisplay image portion14aof FIG. 2B is rotated by 90° with respect to the equivalent display image portion shown in FIG. 2A. Thedisplay image portion14bof FIG. 2B is also rotated by 90° with respect to the equivalent display image portion shown in FIG. 2A. Thecontrol buttons18 of FIG. 2B are also rotated by 90° with respect to the equivalent control buttons of FIG. 2A. The rotation of thecontrol buttons18 is most clearly illustrated by comparingbuttons18aand18bof FIG. 2B with the equivalent control buttons of FIG. 2A. Portions of thedisplay image14, such asdisplay image portions14aand14b, along with thecontrol buttons18, which may also be a display image portion, are rotated and reformatted to conform to the rotated image space of thedisplay device12. Rotation and formatting may be accomplished by any appropriate technique. For example, a raster scan display image may be rotated by simply transposing the horizontal and vertical deflection values. Formatting may then be accomplished to fit the rotated image within the available display image space to reduce any distortion. For a display utilizing pixels, each array of pixels may be transposed and formatted. Examples of algorithms/techniques for reformatting displays include scaling, stretching, and the ability to dynamically update resolution.
• In one embodiment of the present invention, the[0025]display image14 is oriented with respect to the orientation of thedisplay device12. As thedisplay device12 oriented as shown in FIG. 1 is rotated, thedisplay image14 is automatically oriented, such that the appearance of thedisplay image14 appears to remain approximately stable regardless of the orientation of thedisplay device12. Thus, if a viewer prefers landscape mode, she can rotate thedisplay device12 to achieve the orientation shown in FIG. 1. If the viewer prefers portrait mode, she can rotate thedisplay device12 to achieve the orientation shown in FIG. 2B. Note that even though the appearance of thedisplay image14, relative to a viewer, remains approximately constant, thedisplay image14 is actually oriented (rotated and formatted) in response to the orientation of thedisplay device12.
• In another embodiment, the relative orientation between the[0026]display image14 and a viewer (See FIG. 8 for depiction of a viewer36) is approximately constant. Thus, if a viewer tilts her head, thedisplay image14 is tilted in the same direction, such that the orientation between the viewer and thedisplay image14 is approximately constant (fixed). As shown in FIG. 1 and FIG. 2B, thedisplay image14 is rotated to achieve a landscape orientation or a portrait orientation. However, orientation of thedisplay image14 is not limited thereto.
• FIG. 3 is an illustration of rotated self-orienting[0027]display device12 showing the orienteddisplay image14 rotated to achieve an arbitrary orientation. Thedisplay image14 of FIG. 3 is automatically rotated such that the relative orientation between a viewer is approximately constant, regardless of the amount by which thedisplay device12 is rotated. Orientation of thedisplay image14 and/or thecontrol buttons18 is not limited to rotation in a single dimension (e.g., plane). Thedisplay image14 may be oriented in one, two, or three dimensions, as indicated by the three dimensional set ofaxes15. For example, a three dimensional depiction on thedisplay image14 may be rotated horizontally, vertically, or a combination thereof as thedisplay device12 is rotated, such that the relative orientation between a viewer and thedisplay image14 remains approximately the same.
• In another embodiment, the three[0028]dimensional display image14 is oriented to provide a desired perspective to the viewer. This may be accomplished by the viewer simply turning and/or shifting her head to view the desired perspective, turning thedisplay device12 to view the desired perspective, or a combination thereof As explained in more detail below,sensors16 can be positioned on theviewer36 and/or on thedisplay device12 to sense the orientation of the viewer and/ordisplay device12. For example, assume the threedimensional display image14 is a cube and thedisplay device12 is a hand held display device. Also assume the viewer is viewing a front side of the cube. If the viewer desires to view the left side of the cube, she may simply rotate the hand held display device (e.g., to the right) to view the left side of the cube. She may also turn her head (e.g., to the right and/or shift her head to the left), as if the cube were physically in front of her and she positioned herself to look at the left side.
• As mentioned above, various embodiments of the[0029]control buttons18 are envisioned. FIG. 4 is an enlarged illustration of acontrol button18bcomprising an array of light emitting diodes (LEDs). Anexemplary control button18bis expanded to show the array of LEDs utilized to display the shape corresponding to the control function performed by the button. Thecontrol button18bcomprises a triangle shaped image, which may signify play, for example. The LEDs may be various colors. Upon the orientation of thedisplay device12 being sensed, the image ofcontrol buttons18, including18b, are rotated accordingly. In one embodiment, the array of LEDs is symmetric, thus allowing the control button image to be rotated between landscape and portrait mode by transposing the array of LEDs.
• FIG. 5 is an illustration of liquid crystal display (LCD)[0030]control buttons18. Thecontrol buttons18 in FIG. 5 comprise LCD portions for displaying the shape corresponding to the control function performed by the button. As shown in FIG. 5, the LCD portions are covered with anappropriate overlay20 to protect the LCD portions and to provide a surface which can be touched/depressed to utilize thecontrol buttons18. Upon the orientation of thedisplay device12 being sensed, the LCD image ofcontrol buttons18 are rotated accordingly.
• FIG. 6 is an enlarged illustration of a[0031]control button18bthat is automatically oriented by gravity, wherein the control button comprises aliquid portion22 having a shapeddisc24 contained therein. Theexemplary control button18bis automatically oriented by gravity when thedisplay device12 is rotated. Thecontrol button18bof FIG. 6 comprises aliquid portion22 contained within thecontrol button18b. Within theliquid portion22 is containeddisc24 formed in a shape corresponding to the control function performed by the button. Thedisc24 is triangular shaped, indicating the play function, for example. Thedisc24 is suspended in theliquid portion22. As thedisplay device12 is rotated thedisc24 automatically rotates, thus resulting in self-orientation of thecontrol button18b. In one embodiment, thedisc24 is weighted such that aspecific portion28 of thedisc24 is always pointed in the direction of the strongest gravitational pull (e.g., down). Thearrow28 depicts a portion of thedisc24 that is heavier (more mass) such that theportion28 is always facing “down” (toward the strongest gravitational attractive force). In another embodiment, thedisc24 contains an air bubble26 (or other appropriate gas of liquid portion) such that the portion with the lesser mass is always facing “up” (away from the direction of the strongest gravitation pull). Thebubble26 may be any portion comprising a gas or a liquid that is less dense than the liquid in theliquid portion22. Other types ofcontrol buttons18 that are automatically oriented by gravity are envisioned.
• FIG. 7 is an enlarged illustration of a[0032]control button18bthat is automatically oriented by gravity, wherein thecontrol button18bcomprisesbearing34. Self-orientation of thecontrol button18bof FIG. 7 is achieved via gravity in a similar manner as described above with respect to FIG. 6. However, thedisc24 is contained within thecontrol button18bby bearings, or the like, which allow thedisc24 to freely rotate. Again thecontrol button18bshown in FIG. 7 may comprise aweighted portion28, a lessdense portion26, or a combination, similar to thecontrol button18bshown in FIG. 6. Also, other mechanisms for providing a self-orienting display that is automatically oriented via gravity. For example, thecontrol buttons18 may be attached to spindles or axles that allow thecontrol buttons18 to freely rotate.
• FIG. 8 is an illustration of a self-orienting display showing a[0033]viewer36 viewing thedisplay image14, andmultiple sensors16a,16b, and16cpositioned on thedisplay device12. As mentioned above, thesensors16 may comprise any appropriate type and combination of sensors capable of sensing the orientation of an object. Examples of which include known types of devices such as mercury switches, gyroscopic sensors/devices, gravity switches/devices, optical detectors (e.g., infrared detectors), acoustic sensors/devices (e.g., ultrasonic devices, acoustic microphones), electrical sensors/devices, magnetic devices/sensors, and cameras. Thesensors16 may be positioned on thedisplay device12 and/or on theviewer36. Thus, thesensors16 may be positioned on an object, wherein the object may comprise thedisplay device12, theviewer36, another object within sensing range of thesensors16, or a combination thereof.
• For purposes of explaining the following exemplary embodiment, the[0034]sensors16 positioned on thedisplay device12 in FIG. 8 are acamera16a, an acoustic sensor (e.g., microphone)16b, andmercury switches16c. Thecamera16amay comprise any appropriate type of camera, such as a camera utilizing a charge coupled device (CCD), or an infrared camera (e.g., night vision), for example. Thecamera16asenses the orientation of the viewer's36 head. In response to the sensed orientation of the viewer's36 head, thedisplay image14 is automatically oriented by any of the techniques/devices described herein.
• To facilitate automatic self-orientation, in one embodiment, the relative orientation between the[0035]display image14 and the object is initialized. This may include initialization of the relative orientation between thedisplay image14 and thedisplay device12, the relative orientation between thedisplay image14 and theviewer36, or a combination thereof. For example, the relative orientation between theviewer36 and thedisplay image14 is initialized. To generate the initial relative orientation, theviewer36 may position herself in front of thedisplay image14, such that she is within sensing range of the sensors16 (e.g., optical range of thecamera16aand/or audio range of themicrophone16b). While observing her depiction on thedisplay image14, the viewer may position her head to align the depiction to be centered in thedisplay image14, for example. Once the viewer is satisfied that the relative orientation is as desired, she may initialize this relative orientation. All subsequent automatic orientation will be with respect to the initial relative orientation. Initialization may be accomplished by any appropriate means, such as activating a switch, depressing a button (e.g., a control button18), giving an audible command, waiting a period of time, or a combination thereof. In one exemplary embodiment, the viewer gives an audio command, such as “align”. Themicrophone16breceives this audio command, and transduces the audio command into a sense signal. This sense signal is utilized to establish the baseline relative orientation between thedisplay image14 and theviewer36. Thus, theviewer36 may rotate thedisplay device12 to either landscape of portrait orientation. The mercury switches16csenses the orientation of thedisplay device12, also providing a sense signal. The sense signal provided by the mercury switches16cand the sense signal provided by thecamera16bduring initialization are utilized to establish the baseline relative orientation. The sense signals are also utilized to orient thedisplay image14 as thedisplay device12 and/or theviewer36 change orientation. Also, thedisplay image14 may be oriented via an audio command, such as “rotate”, in response to which thedisplay image14 is rotated (e.g., 90°). It is to be understood that various combinations ofsensors16, and placements thereof are envisioned. For example, as shown in FIG. 9,sensors16 may be positioned on theviewer36.
• In yet another embodiment, the[0036]viewer36 is authenticated. Authentication may be accomplished by analyzing the sensed image, which is sensed by thecamera16b, to determine if the viewer is authorized to use thedisplay device12. The sensed image may include a retinal scan, a finger print scan, or the like. The sensed image is analyzed to determine if authorization is appropriate. Any appropriate technique may be utilized to analyze the sensed image. For example, the sensed image may be compared to a stored representation of an authorized image, or the sensed image may be analyzed for key features which distinguish an authorized sensed image, or a combination thereof. In another embodiment, the viewer is authenticated by analyzing a sensed acoustic signal received by theacoustic sensor16c. The acoustic signal may include a key phrase, such as the viewer's36 name or a password. The sensed acoustic signal is analyzed to determine if authorization is appropriate. Any appropriate technique may be utilized to analyze the sensed acoustic signal. For example, the sensed acoustic signal may be compared to a stored representation of an authorized acoustic signal, or the sensed acoustic signal may be analyzed for key features which distinguish an authorized sensed acoustic (e.g., acoustic signature), or a combination thereof.
• FIG. 10 is a functional block diagram of self-orienting display system comprising a[0037]sensor portion40, adisplay processor42, adisplay portion44, and anoptional authenticator44. Thesensor portion40 may comprise any combination of the sensors described above. Thesensor portion40 senses at least one characteristic of an object. For example, the object may be the display device (e.g., display device12) and characteristics may include orientation of the display device; the object may be a user (e.g., viewer36) and the characteristic may include an image of a portion of the user's body (e.g., retina, finger print); the object may be a user and the characteristic may include a acoustic signal provided by the user (e.g., voice), or a combination thereof. Thesensor portion40 provides asensor signal48 indicative of the sensed characteristic (or characteristics) of the object. Thedisplay processor42 receives thesensor signal48 and processes thesensor signal48 to determine the orientation of the sensed characteristic(s). Thedisplay processor42 provides anorientation signal50 indicative of the sensed characteristic(s). The display portion44 (e.g., the display device12) receives theorientation signal50 and orients a display image (e.g., display image14) in accordance with the determined orientation. In one embodiment, the self-orienting display system comprises theauthenticator46 for authenticating the object by analyzing the sensed characteristic(s) of the object. Theauthenticator46 receives thesensor signal48 and analyzes the sensed characteristic(s) using any of the analysis techniques described above. Thissense signal48 and theorientation signal50 may be provided by any appropriate means, such as electrically, acoustically, optically, electromagnetically, or a combination thereof.
• FIG. 11 is a flow diagram of an exemplary process for self-orienting a display. The object is sensed at[0038]step54. As described above, the object may be a person, the display device, or a combination thereof. The characteristic may include orientation of the object, an image of a portion of the object (e.g., retina or fingerprint), an acoustic signal (e.g., voice or clap), or a combination thereof. The object may be sensed by any combination of the sensors described above, such as optical sensors, mechanical sensors, gravity sensors, gyroscopic sensors, electromagnetic sensors, acoustic sensors, touch sensitive sensors (e.g., control buttons18), for example. Atstep56, the object is authenticated as described above. The step of authentication is optional. The relative orientation between the object and the display image is initialized atstep58. The step of initialization is also optional. Initialization may be accomplished described above. Atstep60, the orientation of the object is determined utilizing the sensed characteristic (or characteristics) of the object. The display image is oriented with respect to the determined orientation of the object atstep62. As described above, the display image may be oriented to predetermined orientations, such as portrait, landscape, rotation in a predetermined number of degrees, or a combination thereof. The display image may also be oriented such that the orientation of the display image appears approximately constant (e.g., fixed) regardless of the orientation of the object. For example, a display image will appear to rotate and/or tilt in the opposite direction of the rotation and/or tilt of the display device.
• A method for self-orienting a display image as described herein may be embodied in the form of computer-implemented processes and system for practicing those processes. A method for self-orienting a display image as described herein may also be embodied in the form of computer program code embodied in tangible media, such as floppy diskettes, read only memories (ROMs), CD-ROMs, hard drives, high density disk, or any other computer-readable storage medium, wherein, when the computer program code is loaded into and executed by a computer, the computer becomes a system for practicing the invention. The method for self-orienting a display image as described herein may also be embodied in the form of computer program code, for example, whether stored in a storage medium, loaded into and/or executed by a computer, or transmitted over some transmission medium, such as over the electrical wiring or cabling, through fiber optics, or via electromagnetic radiation, wherein, when the computer program code is loaded into and executed by a computer, the computer becomes a system for practicing the invention. When implemented on a general-purpose processor, the computer program code segments configure the processor to create specific logic circuits.[0039]
