Description

Detailed Description of the Invention

[Correlation with related applications]
This is a continuation of the title "Adaptive Display System" filed on October 11, 2002 by Zacks et al. The present invention generally relates to display systems.

[Background of the invention]
Larger video systems such as back and front projection television systems, plasma displays, and other types of displays are becoming increasingly popular and affordable. Often, such large-scale video display systems are used to produce audio or visual content to audience members in a more immediate and fun manner, such as Sarande Sound or other advanced audio systems. Adapted to. Many new homes and offices are even built with media rooms and amphitheaters designed to accommodate such systems.

  Increasingly, such large video display systems are also used in personal computing systems, Internet facilities, digital cable programming, and such large video display systems in videoconferencing, simulation, and games. Like interactive web, based on a television-based interactive web television system that allows it to be used as part of advanced image applications such as interactive programming, immersive programming and general purpose computing It is effectively combined with other information processing technologies. In many of these applications, large video display systems are used to show confidentiality information such as money transactions, medical records, and personal communications.

  As a special value, as a component of a medical information system that provides hospitals or outpatients with information management for medical data such as hospital information systems (HIS) or radiographic information systems (RIS) There is the use of scale video display systems. This environment includes a wide variety of patient related types such as computed tomography, ultrasound, magnetic resonance imaging, digital radiography, or types of imaging generated by systems such as computer radiography. Large scale video display systems can be used to provide content. Such large video display systems are also useful for applications using the types of images used for telemedicine, telehealth and other forms of telemedicine procedures and consultation.

  One inherent problem in the use of such large video display systems is to display the content on such a large visual scale so that the content can be observed over a very large display area. Thus, an observer who may be located at a considerable distance from the display system may be able to observe the content without the consent of the intended audience members. This issue is particularly acute in the medical industry, as the privacy of medical records, diagnostic images, and other medical information is paramount. The policy on medical equipment and / or legal requirements is that only designated physicians and staff members have access to specific medical images and other patient information. In addition, there may be various levels of restrictions enforced. For example, when attending a set of medical providers for a patient, a medical record containing images and patient data may have access to unlimited access. However, another set of providers may be granted access only to specific images and data associated with a specific injury or treatment.

  One way to prevent sensitive content from being viewed by unintended audience members is to place physical restrictions around the display system so that the image displayed on the display can be controlled. Visible only in the designated area. Walls, doors, curtains, barriers, and other simple physical block systems can be effectively applied for this purpose. However, establishing such physical restrictions is often inconvenient and sometimes impossible. Therefore, other means are needed to provide the confidentiality and security necessary for such large scale video display systems to be used to present confidentiality or confidential content.

  Another approach is for large video display systems to appear and present images with a very narrow viewing angle to the display. For example, with the exception of a very narrow angle of view, a polarizing screen can be placed between the audience member and the display to prevent the propagation of modulated light in the image emitted by the display. This approach is often not preferred because the narrow angle of field of view limits the range of locations where people can observe the image presented on the display.

  Another approach is to use the known indicators and intended when an unintended audience member enters the presentation space or when an audience member feels that an unintended audience member is likely to enter the presentation space. Use of a display control program associated with the display, using a delete button or switch that can be triggered by the audience member. When the erase switch is manually triggered, the indicator system is instructed to stop displaying sensitive content and / or display different content. It will be appreciated that this approach requires at least one audience member that allocates attention to what is being presented and the task of monitoring the presentation space. This places an unnecessary burden on the audience members controlling the erase switch.

  Yet another approach involves the use of human phase recognition algorithms. US Patent Application No. US2002 / 0135618 filed February 5, 2001 by Maes et al. "System And Method for Multi-Modal Focus Detection, Referential Ambiguity Resolution and Mood Classification Using Multi-Modal Input" Disclosed is a system in which human phase recognition algorithms and other algorithms are combined to assist a computer system in order to interact. In the approach described there, a multi-mode input is provided to help the system interpret the command. For example, the voice recognition system can interpret the command while the video system is determining who issued the command. However, the system described therein does not take into account the problem of preventing viewing of secret or unauthorized content on the display.

  Therefore, what is needed is to automatically display the secret medical image and the contents displayed automatically to ensure that the record presented on the display system is presented in a way that preserves the confidentiality of the record. A display system and a display method for adjustment.

Detailed Description of the Invention
FIG. 1 shows a first embodiment of a presentation system 10 of the present invention adapted to present content. As used herein, the term content refers to any form of speech, audio, text, emotional, or graphical information or representation and combinations thereof.

  In the embodiment shown in FIG. 1, the presentation system 10 receives an analog television, digital television, computer monitor, projection system or signal containing image or visual content and identifies the signal in presentation space A. A display device 20 such as another device capable of being converted into a possible image. The display device 20 includes an image modulated light source 22, such as a cathode ray tube, a liquid crystal display, an organic light emitting device, an organic electroluminescent device, or other type of display element. Alternatively, the image modulated light source 22 can include any of the well-known front or rear projection display devices, holographic and / or immersive type display devices. A display driver 24 is also provided. The display driver 24 receives the image signals and converts these image signals into control signals for causing the image modulation light source 22 to display an image.

  The presentation system 10 also includes an audio system 26. Audio system 26 may include a conventional mono or stereo sound system that can display the audio component of the content in a manner that can be detected anywhere within presentation space A. Alternatively, the audio system 26 may comprise a surround sound system that provides a systematic way to provide two or more channels of associated audio content to the presentation space A. Audio system 26 may also include other types of audio systems that can be used to direct audio to specific portions of presentation space A. One example of such a directional audio system is the US patent application Serial No. 09 / 467,235 assigned to the assignee of the present invention Serial No. 09 / 467,235, filed December 20, 1999, entitled “Directed Audio” It is disclosed in “a pictorial display device”.

  The presentation system 10 also incorporates a control system 30. The control system 30 includes a signal processor 32 and a controller 34. Content supply 36 provides signal processor 32 with signal content. Content supply 36 includes, for example, digital video disc players, video cassette players, computers, digital or analog video or still cameras, scanners, cable television networks, the Internet, other information communication systems, electronic memory or presentation content Other electronic devices capable of transmitting signals including The signal processor 32 receives the content and adapts the content for presentation. At this point, the signal processor 32 extracts the video content from the signal having content and causes the image modulated light source 22 to display the video content for display. Similarly, the signal processor 32 extracts an audio signal from the content having the signal. The extracted audio signal is provided to audio system 26, which converts the audio signal into an audible form that can be heard in presentation space A.

  The controller 34 causes the image modulated light source 22 to display the image received by the signal processor 32. In the embodiment shown in FIG. 1, a user interface 38 is provided to allow local control over various features of the display device 20. For example, the user interface 38 can be adapted to allow one or more audience members to enter into system adjustment preferences such as color, contrast, brightness, volume, content channel selection, and the like. The controller 34 receives signals characterizing the adjustment requested by the user from the user interface 38 and provides appropriate instructions to the signal processor 32 so that the image presented by the display device 20 assumes the requested system adjustment. .

  Similarly, for presentation by the presentation system 10, the user of the presentation system 10 may enter an input to enable or disable the presentation system 10 and / or select a specific channel of content. Can be adapted to do. User interface 38 may include other inputs for use in calibration, as will be described in more detail below. For example, the user interface 38 can be adapted to a voice recognition module that recognizes audible signals and provides recognition to signals that can be used by the controller 34 to control the operation of the device.

  In addition, a presentation space monitor system 40 is provided in the sample presentation space A in order to detect in the presentation space A an element that affects whether or not certain contents are presented. As described above, the presentation space A may include any space or region where the content presented by the presentation system 10 can be determined. Presentation space A can take many forms. For example, in the embodiment shown in FIG. 1, the content presented by the display device 20 is limited by the wall 51. Instead, if the presentation system 10 is implemented in an open space such as a display area at a retail store, a railway station or an airport terminal, the presentation space A will be limited by the optical display capabilities of the presentation system 10 . Similarly, when the presentation system 10 is operated in a mobile environment, the presentation space A is moved as the presentation system 10 is moved.

  In the embodiment shown in FIG. 1, the presentation space monitor system 40 comprises an analog or digital image capture comprising a photographic lens unit 44 that focuses light from a scene onto an image sensor 46 that converts the light into an electrical signal. A conventional image capture device such as unit 42 is provided. The taking lens unit 44 and the image sensor 46 cooperate to capture an image including the presentation space A.

  The image captured by the image capture unit 42 is supplied to the signal processor 32. The signal processor 32 analyzes the image to detect image elements in the image for the captured presentation space A. Examples of image elements that can be found in presentation space A include audience members 50, 52, and 54 or doors 56 or windows 58 or others that may have an impact on what is presented by the presentation system 10 Includes items. Such other items can also include content capture devices such as video cameras, digital still cameras, or any other image capture device similar to an audio capture device. A source of element profiles 60 is provided.

  The source of the element profile 60 may be a memory element, such as an optical, magnetic, or electronic storage device or a storage device provided by a remote network. Also, the source of the element profile 60 can comprise an algorithm for execution on a processor such as the signal processor 32 or the controller 34. Such an algorithm determines profile information based on the analysis of elements found in the presentation space image obtained by the image capture unit 42, and makes the profile identified elements as described with respect to FIG. assign.

  FIG. 2 shows a flowchart for one embodiment of a method for operating a presentation system, such as presentation system 10. As shown in FIG. 2, the presentation system is first calibrated (step 110). As shown in FIG. 3, during calibration, a calibration image including an image of presentation space A is obtained (step 112). Use calibration images to identify elements that are or can exist in presentation space A (step 114), and may be present in each, and a profile is determined for each element ( Step 116).

  Elements identified during calibration can include, for example, audience members 50, 52, 54, etc. present in presentation space A. By using face recognition or other software to analyze the image or multiple images of the presentation space, such people can be identified. In this regard, the calibration images used during calibration include images of specific people or their specific characteristics that can be used in face recognition software to help identify people likely to be in the presentation space be able to. Profile information is assigned to each person. A profile specifies the nature of the content that a person is entitled to observe. For example, when it is determined that a person is an adult audience member, the viewing rights may be wider than the viewing rights associated with members of a child audience. In another example, an audience member may have a means of accessing information not available to other adult audience members that is selected for the other adult audience member in connection with an untouched adult. Good. Profiles can be assigned viewing rights in a variety of ways. For example, viewing rights can be determined with respect to ratings such as those provided by the American Animation Association (MPAA) in the US, California, Encino. When this is complete, each element is associated with one or more ratings, and the viewing rights associated with the element are determined with the associated ratings. However, it will also be appreciated that it is possible to assign profiles without individually identifying audience members 50, 52, and 54. Once this is done, the profile can be assigned to a class viewer. For example, people in presentation space A can be classified as adults and children with one set of rights related to the adult class of audience members and another set of rights related to the class of children.

  In addition, profile information can be assigned to elements other than people. Profiles can be assigned to items such as windows, doors, blinds, curtains and other objects in presentation space A. For example, when the image indicates that the door is open, assign a profile describing one level of display rights to door 56, another set of rights when the door is partially open, and the door When is closed, another set of rights can be assigned.

  In another example, windows 58 can be assigned profiles that provide various viewing rights related to window conditions. For example, when no viewer is detected outside the window 58, one set of rights is assigned to the window, and when no viewer is detected outside the window 58, another set of rights is assigned to the window.

  In yet another example, the presentation space monitoring system 40 can identify an imaged portion of the presentation space A (a portion that does not change frequently, such as a carpet region or furniture) as a static region element. A profile that identifies the viewing rights that are enabled when a static area element changes while presenting an image can be assigned to the static area element.

  In another example, the image capture unit 42 can identify the portion of the presentation A that is imaged and is not expected to change during the display of the content, and that change is a determination of the rights associated with the content. Not related to frequent. For example, a large box clock (not shown) can be present in the scene. The watch has a turn hand and a moving pendulum on its face. Thus, if the content is presented for a certain period of time, the change will occur in the appearance of the watch. However, these changes are not related to the right to see. Therefore, these areas are identified as fluid elements, and each fluid element indicates how changes in the fluid element should be ignored when deciding what content to present. A profile is assigned.

  Finally, it may be useful to determine a set of rights states for presentation space A when unknown elements are present in presentation space A. For example, it may be useful to determine a profile for an “unknown” element. The profile of the unknown element is used to determine the rights setting where an undefined change in the unknown person or element occurs.

  The calibration process is described as a manual calibration process, but for a pre-determined class of elements, in automatic mode by scanning the presentation space to search for a pre-determined user class It will also be appreciated that a calibration process can be performed.

  Once calibrated, the presentation system 10 determines the desire to view the contents and enters a display mode (step 120). This desire is typically indicated using the user interface 38. However, the presentation system 10 is, for example, programmed to cause the controller 34 to move the presentation system 10 at a specific date or time, for example, the controller 34 has received a new signal for presentation on the display. Is activated by the controller 34 and determines that the presentation system 10 should be activated.

  The signal processor 32 analyzes the signal having content and determines the access rights associated with this content (step 130). Access rights specify the state or set of states that are recommended or required to view the content. Access rights identify the state or set of conditions that are recommended or required to view the content. For example, MPAA evaluation can be used to determine access rights. Instead, access rights can be determined by analysis of the proposed content. For example, if a display is required to present digital information, such as a computer, the content of the information can be analyzed based on the information contained in the content, and an evaluation can be assigned. Also, access rights for specific content can be manually assigned during calibration.

  In yet another alternative, audience members may define the content of a class that the audience member wants to determine access rights. For example, audience members can define higher levels of access to personal content. When the content is analyzed, a scene that includes personal content can be identified by analyzing the content or by analyzing metadata associated with the content that indicates the personal content. Then, such contents can be automatically associated with an appropriate access right. Then, the presentation space A is sampled (step 140). In this embodiment, this sampling is performed when the image capture unit 42 captures an image of the presentation space A. Depending on the optical properties of the presentation space monitor stem 40, it may be necessary to obtain different images at different depths of the field, so that the obtained image can allow identification of elements in the scene. Express the entire presentation space with the focus of.

  The image or images are then analyzed to detect elements in the image (step 150). Image analysis can be performed using pattern recognition or other known image analysis algorithms. A profile for each element in the image is then obtained based on this analysis (step 160).

  Then, the content to be presented in the presentation space A is selected (step 170). If more than one element is identified in presentation space A, this step involves combining element profiles. There are various ways to do this. Element profiles can be combined in an additional manner with each selected element profile and selected content based on the sum of the rights associated with the element. Table 1 shows an example of this type. In this example, three elements (adult, child, and open door) are detected in the presentation space. In this example, viewing rights are based on the MPAA rating scale.

  As can be seen in this example, the combined viewing rights include all of the adult viewing rights, while the child and open door elements have fewer viewing rights.

  In addition, profiles can be combined by a subtraction method. When this is done, the profile for each element in the presentation space is examined, and the rights for the audience are, for example, the lowest level of rights associated with one of the profiles for one of the room elements. Pulled down. An example of this is shown in Table 2. In this example, the presentation space includes the same adult, child and open door elements as described in connection with FIG.

  However, when viewing rights are combined in a subtractive manner, the combined viewing rights are limited to the rights of the element with the lowest set of rights (open door elements). Other configurations can also be established. For example, a profile is an element that has a viewing profile associated with each type of content, with content type analysis such as violent content, mature content, financial content, or personal content. Can be determined. As a result of such a combination, the set of viewing rights for the element is determined and can then be used to make a selection decision.

  Content is then selected based on the combined profile for the element and profile for the content (step 170). The combined element profile yields a set of viewing rights. This set of viewing rights can be compared with the rights information obtained from the content profile. Content having a set of access rights corresponding to the set of viewing rights is selected for presentation. In the example of Table 1, the PG rating corresponds to a combined viewing right that includes G, PG, and PG-13 rating content, so that the content of the PG rating can be selected for presentation. Conversely, in the example of Table 2, since it does not correspond to the viewing right combined with PG evaluation (in the case of Table 2, it is limited to G evaluation), PG evaluation cannot be presented. As noted above, viewing rights and access rights can be assigned in different ways. Thus, the selection process can be performed in different ways.

  For example, if the content is received in multiple streams, such as multi-cable channels, selected programming or selected channels can be blocked. When the content comprises a single stream of content, such as a movie recorded on a digital video disc, the selected video disc and / or a selected portion of the content can be excised. By analyzing the text-based content and cutting out all blocked or particularly sensitive parts, financial and other text-based information can be identified.

  In one alternative embodiment, a first stream of content can be utilized by having a portion associated with a reduced set of access rights and a portion associated with an increased set of access rights. Having a content portion corresponding to a portion of the first stream having an increased set of access rights, but having content modified to have a lower set of access rights, a second stream of content Can be used. In this example, the step of selecting content for presentation determines that the viewing rights set does not correspond to a larger permission set associated with the first stream portion of the content; and In order to replace such a portion of the first stream, it comprises selecting the content of the presentation from the second stream of content.

  The selected content is then presented (step 180) and the process is repeated until it becomes necessary to stop presenting the content (step 190). During each iteration, changes in the presentation space element composition can be detected. For example, such changes occur when people move around in the presentation space. When such a change is detected, the manner in which the content is presented can be automatically adjusted to adapt to this change. For example, when audience members move from one side of the presentation space to the other side of the presentation space, the content presented, such as text, graphics, and video elements in the display, is displayed on the display to optimize the visual experience. Can be changed in relation to

  Other user preference information can be incorporated into the element profile. For example, as noted above, the presentation system 10 can receive system adjustments through the user interface 38. In one embodiment, these adjustments can enter during the calibration process (step 11O), and the presentation space monitor system 40 can determine which audience members have entered what adjustments and Can be adapted to incorporate adjustment preferences in profiles for image elements associated with audience members. During operation, the elements in presentation space A are determined to be associated with a particular audience member, signal processor 32 can use the system's adjustment preferences to adjust the presented content. When one or more audience members are identified in presentation space A, system adjustment preferences are combined and used to drive the operation of presentation system 10.

  As explained above, the presentation space monitor system 40 comprises a single image capture unit 42. However, the presentation space monitor system 40 can also include one or more image capture units 42.

  As shown in FIG. 4, the presentation system 10 can be effectively applied for video conferencing purposes. In this regard, using audio system 26, user interface 38, and image capture unit 42 to send and receive audio, video, and other signals that can be transmitted to a compatible remote video conferencing system Can do. In this application, the presentation system 10 can receive a signal containing content from a remote system and display a video portion of the content on the display device 20. As shown in this embodiment, the display device 20 provides a real or virtual mirror image obtained from the captured image of the presentation space A to the portion 200 of the reflected image showing the user 202. The received content portion 204 of the display device 20 shows a video portion of the received content. The portion 200 of the reflected image and the portion 204 of the received content can be sized differently or can be fluidly adjusted by the user 202. The audio portion of the content is received and output by the audio system 26, which in this example includes the speaker system 206.

  In the embodiment described above, the presentation space monitor system 40 is described as sampling the presentation space A using the image capture unit 42. However, the presentation space A can be sampled in other ways. For example, the presentation space monitor system 40 can use other sampling systems such as a conventional radio frequency sampling system 43. In one popular form, the elements in the presentation space are associated with a unique radio frequency transponder. The radio frequency sampling system 43 includes a transceiver that outputs a polling signal to which the transponder in the presentation space responds with a self-aware signal. The radio frequency sampling system 43 identifies elements in the presentation space A by detecting the signal. In addition, radio frequency signals in the presentation space, typically output by a recording device, can also be detected. Also, other conventional sensor systems 45 can be used to detect elements in the presentation space and / or to detect the state of elements in the presentation space. Such detectors include switches and other transponders to determine whether the door is open and whether the window blind is open. Elements detected using such a system can be assigned a profile during calibration in the manner described above, which determines the combined viewing rights. Also, the image capture unit 42, the radio frequency sampling system 43, and the sensor system 45 can be used in combination within the presentation space monitor system 40.

  In some installations, it may be beneficial to monitor an area outside presentation space A but close to presentation space A to detect elements such as people who may be approaching the presentation space. . This allows the content on the display or the audio content associated with the display to be adjusted before the presentation space A is invaded or penetrated, as before the audio content is detected . The use of multiple image capture units 42 may be usefully applied for purposes such as the use of a radio frequency sampling system 43 or a sensor system 45 adapted to monitor such areas.

  With reference to FIG. 5, the presentation system 10 and the display device 20 are shown as part of a larger diagnostic imaging and recording maintenance system 220 on the network 222. In the example of FIG. 5, the diagnostic imaging and recording maintenance system 220 includes a patient database 224 that includes content relating to the patient including, but not limited to, patient data and medical images. The diagnostic imaging and recording maintenance system 220 also includes one or more image capture systems 226, such as x-rays, ultrasound devices, other testing or monitoring facilities, that can provide information to be communicated to the patient. Also, in the illustrated embodiment, diagnostic imaging and recording maintenance system 220 includes an enhanced display 228 that provides features such as stereoscopic 3D images and recording services 230.

  As shown in the schematic form of FIG. 5 and the perspective view of FIG. 6, the display device 20 is located in an observation room 240 that provides an environment suitable for visual and assessment of patient-related content. As shown in FIG. 6, the viewing room 240 includes other forms of display device 20, an enhanced display device 228, and a lighting box 232 for viewing normal medical images such as x-ray fluoroscopy. A diagnostic imaging system is incorporated. The lighting box 232 has the ability to both view normal medical images and provide additional images and information obtained from the network, communication systems (not shown), other well-known medical image processing and It can have information supply information (not shown). The display device 20 can present medical images and information so that people 50 and 52 in the presentation space A can see the contents of the images.

  FIG. 7 shows a flowchart describing a first implementation of a method for operating the presentation system 10 as part of the diagnostic imaging and maintenance system 220. In the embodiment of FIG. 7, in the first step of the method, personal identifiers are detected for people located in the presentation space A (step 250). This can be done in various ways. In one embodiment, this is performed using a sensor system 242 provided by the presentation system 10. Sensor system 242 scans presentation space A and additionally near presentation space A to identify persons 216 and 218 in and near presentation space A. The sensor system 242 may comprise any form of the presentation space monitoring system 40 described above, and may monitor the presentation space A and other areas using the techniques described above. it can.

  In the embodiment of FIGS. 5, 6 and 7, the step of detecting personal identifiers within presentation space A is performed by detecting personal identifiers 234 associated with people 216 and 218. In particular, in the embodiments shown in FIGS. 5, 6 and 7, each personal identifier 234 has a radio frequency transponder as described above, and the sensor system 242 may be a transceiver or the like as described above. A conventional radio frequency sampling system 43 is used to detect the radio frequency transponder.

  In another embodiment, if the personal identifier to sensor system 242 is not people 216 and 218 that control access to viewing room 240 by controlling the operation of door 244, then viewing room 240 will have people 216 And does not allow people like 218 to access the viewing room 240. Thus, people 216 and 218 cannot enter presentation space A without first providing a personal identifier. In this way, a personal identifier for each person in the presentation space A can be determined. With this implementation, the sensor system 242 can comprise the radio frequency sensing system described above, or can comprise a magnetic card stripe reader, an optical card reader, or similar device.

  Each detected personal identifier 234 provides information that can be used to identify a person, such as person 216 or person 218, associated with personal identifier 234. Controller 34 uses this identifying information to determine a profile for each detected personal identifier (step 252). This can be done in various ways. For example, each personal identifier 234 can have a memory (not shown), and profile information associated with the person having the personal identifier 234 is stored in that memory. In another embodiment, diagnostic imaging and recording maintenance system 220 may incorporate a person database 236, which maintains information such as a profile for each person authorized to view the chart. And the display controller 34 or database 222 provides information that can determine whether a person is allowed to have the means to access a particular chart.

  Also, the profile for each person can incorporate authentication information. If such authentication information is provided, an optional authentication step 254 can be performed. The authentication information identifies the authentication action to be performed by the identified person and is used to ensure that the person who presents the physically personal identifier 234 is actually the person assumed by the system Information regarding its actions that can be associated with the personal identifier 234. The authentication operation comprises biometric features for biometric input such as password input, personal identification number, audio signal, thumb fingerprint trace scan, retina scan, or other such input Can do. As an audio input system, the authentication input system 229 shown in FIG. 5 receives such an authentication input and generates an authentication signal. The received authentication signal is compared with the authentication signal associated with the personal identifier 234. If the received authentication signal corresponds to an authentication signal associated with the personal identifier 234, the identity of the person with the personal identifier 234 can be considered legitimate.

  It will be appreciated that a profile can be assigned to a personal identifier that is uniquely associated with a person. Alternatively, a categorized type profile can be provided for each personal identifier 234. When this is complete, each personal identifier classifies each person associated with personal identifier 234 as a person in the class. A viewing right is assigned to each detected personal identifier 234 based on the class of persons associated with the personal identifier 234.

  Once the controller 34 identifies and optionally authenticates the identity of each person in the presentation space A, patient content associated with such people can be obtained. This is also performed using the information stored in the profile for each personal identifier (step 256). In this regard, each profile may include viewing rights that identify patient content that each person in presentation space A is entitled to view, or that identify a general classification. Controller 34 and audience member 50 can use these viewing rights to determine whether to present or provide patient content associated with a particular patient.

  For example, the content of one type of patient can be automatically considered confidentiality that requires specific viewing rights based on legal definitions and institutional policies. Instead, access rights can be assigned to selected patient content that more clearly determine the level of viewing rights required to view the content. In this alternative, the controller 34 simply compares the access rights of the selected content with the viewing rights associated with such person 216 to determine if the selected content is made available.

  As noted above, multiple people are often located in the presentation space A when the selected content is presented. In such a situation, each person is entitled to viewing rights from a profile associated with each personal identifier 234 detected in presentation space A, or optionally in the vicinity of presentation space A, and the viewing rights. Are combined to be used to determine if the selected content is available.

  And the content based on the content of the obtained patient can be presented. The presented content can comprise, for example, the obtained content actually associated with the patient and the patient content obtained from the obtained patient related content. For example, the presented content may comprise a summary of the statistical analysis of the patient content, charts and graphs based on the patient content, and / or warnings and cautions based on the obtained patient content .

  Since people are often associated with the treatment of one or more patients, the controller 34 determines which patient content is associated with people such as people 216 and people 218 in presentation space A and these When people are first detected, they can operate in a mode that presents a list of available patients associated with the detected people. This list can be provided in a way that does not include secret medical or other patient content. Once such a list is provided, the authentication step can be postponed until a selection is made from the list (step 254).

  As shown in FIGS. 5 and 6, the viewing room 240 can include a light source, such as a light 238 from directly above, in addition to the display device 20, which generates light that impedes the presentation of content by the display 10 Let Thus, the presentation system 10 is adapted to interact with ambient light, such as overhead lighting, and a controller that adjusts the angle of lighting to improve the perceived appearance of the presented content Can have 34. Such adjustments can be made based on the content and type of profile information. Similarly, controller 34 can be adapted to control the operation of enhanced display device 228 or lighting box 232, resulting in content for people who do not have suitable viewing rights or are not authorized. Not present.

  Although the invention has been described in detail with particular reference to certain preferred embodiments thereof, it will be understood that variations and modifications can be effected without departing from the spirit and scope of the invention. In this regard, the various elements of the presentation system 10 shown in FIG. 1 can be combined, separated, and / or combined with other elements to obtain the claimed features and features of the present invention.
