## Background
TECHNICAL FIELD
The exemplary embodiments of this invention relate generally to computer software, the visual display of information including text and images, user interfaces and devices including converged communications, touch screen and pen-based image creation and display systems, mobile and wireless applications, visualization and augmented reality software, as well as to collaborative applications, content management and Web technology including pervasive Web technologies.
BACKGROUND
Modem user interfaces can include large format electronic touch sensitive display panels used in conjunction with a pointing device embodied as an electronic “pen”. One non-limiting example of this type of user interface is represented by Interactive Plasma Display (IPD) technology that includes an electronic pen system used with an interactive plasma display. In one exemplary type of IPD system the pen system enables multiple different pens to be distinguished and uniquely identified. For example, one pen may cause the plasma display to render a marking in one color (e.g., red) while another pen may cause the plasma display to render a marking in a different color (e.g., green). Different pens can also be associated with different users enabling markings made (in any color) by one user to be distinguished from a marking made by a different user. An IPD system can advantageously enable high-speed drawing/simultaneous multiple drawing with high image quality, and can also support wireless connections to multiple external devices such as PCs and/or tablet devices whereby a marking made on the display panel can be reproduced on the display of any connected external device(s).

DETAILED DESCRIPTION
For convenience the embodiments of this invention will be described in the context of an IPD system. It should be appreciated however that the embodiments of this invention are not limited for use with any particular type of display technology. For example, and as non-limiting embodiments, the display technology could be based on a touch-sensitive plasma display system, or it could be based on a touch-sensitive liquid crystal display (LCD) system, or on a cathode ray tube (CRT) type of display system having an ability to detect the proximity of a pointing device. The pointing device could be any type of device that can be sensed by the touch-sensitive display including, but not limited to, an electronic pen or stylus, a non-electronic pens or stylus, or even the finger of a user. The electronic pen can have at least unidirectional wireless (RF or IR) connectivity to the display screen so that a location of the pen tip relative to a display screen coordinate system can be detected. The wireless connectivity can also enable individual pens to be uniquely identified and distinguished by the display system, such as if each pen transmits a specific radio frequency, or transmits a unique identification code.
One exemplary and non-limiting type of display system, specifically an IPD system, suitable for use in implementing the embodiments of this invention is described in a document: “Operating Instructions Network Operations Interactive Plasma Display, Model No.: TH-65PB1U, 2012, Panasonic®.
The embodiments of this invention beneficially leverage a pen system with the interactive nature of a display and provide an ability to designate content placement and retrieval onto the display. Content is populated as a user or users draw onto the display. However, and in opposition to the use of conventional static whiteboards, it is no longer required that content remain only at the position where the content is first placed. Instead, if it is desirable to move some content from a first position to a second position the content can be saved and subsequently retrieved to the second position.
The embodiments of this invention also enable a user to retrieve and display some other content, such as image content retrieved from the Web. The image content can be a static image or a video.
FIG. 1 shows a simplified block diagram of a system 10 that is suitable for implementing the various examples of embodiments of this invention. The system 10 is assumed to include a display system 12 that includes a touch sensitive display 14, such as a plasma display, or an LCD, or a CRT display as examples. One or more pens 15, such as electronic pens that transmit wireless signals, can be provided. A controller 16 can be integrated with or provided separate from the display 14 and functions to generally control the sensing of the type/identity and position of the pen 15 relative to the surface of the display 14 and to render corresponding markings on the display 14, such as various color markings depending on the specific pen 15 that is used. The controller 16 can be implemented using, for example, one or more microprocessors connected with program and data storage memory (not shown). The display system 12 also includes at least one interface to external devices, such as a wireless interface 18 to one or more connected devices 19 implemented using wireless links (e.g., BluetoothTM) links 18A. The connected devices 19 could be, for example, personal computers (PCs), laptop computers, tablet-based computers and/or smartphones. As an example, an image displayed on the display 14 can be transmitted to the connected devices 19 for display on a local associated display.
A separate interface can be provided to establish a communication path 22 from the controller 16 to a host system 40 such as one embodied in a PC or a work station. The host system 40 can include at least one data processor 20 connected with a memory 24 that stores data and at least one program 26 that is configured so as to implement the embodiments of this invention. Connected with the data processor 20 is an interface (I/F) 28 for connecting to a network 30, such as a local area network (LAN), a wireless LAN (WLAN), and/or a wide area network (WAN) such as the Internet. An optional local or remote database (DB) 32 can be included and connected with the data processor 20 for the storage of user-generated content and other data as will be described below.
In some embodiments the communication path 22 can be a part of the network 30. In some embodiments the communication path 22 can be implemented using the wireless links 18A. In some embodiments the communication path 22 can be a dedicated signal path for connecting the display system 12 to the host system 40. In some embodiments the display system 12 can be an off-the-shelf display system, such as a commercially available IPD, and is interfaced to the host system 40 via the communication path 22. In some embodiments the functionality of the host system 40 can be integrated with the functionality of the display system 12. In this case the display system 12 as provided to a user can implement the conventional pen sensing and display functionality of the display system as well as the enhanced functionality made possible by the use of the embodiments of this invention. The overall system 10 can find use in a number of exemplary environments including, but not limited to, educational environments (as a replacement for the conventional blackboard and chalk) and business/enterprise environments (as a replacement for a conventional whiteboard and erasable marker(s)).
Some examples of use cases for the system 10 are discussed now in relation to FIGS. 2A and 2B.
In FIG. 2A the user writes or draws on the (IPD) display 14 and creates what can be referred to as ‘markings’ that are displayed on the screen of the display 14. The user can save markings appearing on the entire screen display or on one or more sections of the screen display. In the example of FIG. 2A it can be assumed that the user has created using a pen 15 various markings that form an image (content) 60A that represents a dog. The user can then designate the content to be saved, such as by drawing a line 50 around the content 60A, or by tapping or double tapping within the image 60A, as two non-limiting examples. Further, the selection of content to be saved can be implemented such that all rendered content related to some particular pen color is selected and saved. For example, if a certain user is rendering content with a ‘blue’ pen color then the command to save content (e.g., double-tapping with the blue pen at some location) causes all rendered ‘blue’ content to be saved.
Having thus identified to host system 40 by some means the image 60A that is desired to be saved the host system 40 can then, in one non-limiting embodiment, prompt the user on the display 14, via the communication path 22 and controller 16, to provide a specific, descriptive name for a file to contain the data representing the image to be saved and possibly also a file type. In this example the user responds by entering (e.g., writing on the display screen) a name for my ‘mydog’ (e.g., “Spot”), which may be saved by default as, for example, a .gif file type or as any suitable file type. The file name (e.g., “Spot”) could be entered by the user on the display 14 using the pen 15 and subsequently recognized by the host system 40 using any suitable type of handwriting recognition algorithm. The prompting and data entry could occur in some predetermined portion of the area of the display 14, e.g., in a box in the lower-right corner, or at any convenient location such as directly adjacent to the designated image content 60A.
In some embodiments, and should the user fail to input a specific file name, a default condition can be to use as a non-limiting example optical character recognition (OCR) to translate a portion of text or image to provide or suggest, for example, a unique name, or a general name, or a temporary name (e.g., in cache) until the user specifies a specific file name.
In some non-limiting embodiments the content can be saved under a user name alone or under the user name with some additional contextual information such as time, date and/or location. As one non-limiting example, and as will be discussed in further detail below, if a certain pen such as the ‘red’ pen is identified with a particular user or group of users, e.g., “Sally”, or “Marketing”, then all content created using the red pen can be saved and later recalled under that user identification, e.g., “filename: Marketing, date, time, Conference Room A”.
In some embodiments this user interface could be or could include an audio user interface such as one using speech synthesis and/or speech recognition algorithms in conjunction with suitable audio transducer(s). For example, the user is prompted to provide a name for the saved image data through an announcement made by a speech synthesis system via a loudspeaker, and the user replies by speaking the name that is captured by a microphone and the generated audio signal is converted to text.
In response to the user input by whatever means the host system 40 saves the image content 60A under the specified filename, e.g., ‘mydog.gif’. The image content can be saved in the memory 24 or in the database 32. The content can also be saved via the network 30 to some remote (e.g., cloud-based) data storage medium. When the image content 60A is saved the displayed image can be automatically removed from the display 14 or it can be retained, as desired by the user. The saved image content can be for a specific instance of an object, e.g., ‘mydog’, or for a generic instance of an object, e.g., ‘dog’.
Subsequently the user can issue a command to retrieve the content from storage and can designate a (second) location, such as by tapping on the surface of the display 14, at which to restore (re-display) the retrieved content. In response to the user providing a name, which can be selected from a list of names (a list of file names previously stored) provided by the host system 40 on the display 14, the host system 40 retrieves the corresponding stored image content and sends it to the display system 12 to be displayed at the designated location as the image content 60B.
The second location can be any location on the display screen 14. For example, the user could replicate the image instance at one or at multiple locations on the display screen 14. Further by example the image could be recalled and reproduced at the first location (origin of capture) if some time period has elapsed (e.g. later in time or context). As such, the ‘second location’ can be construed to be the original location where the content was placed on the display screen 14, or one other location on the display screen 14, or multiple other locations on the display screen 14, or the original location and one or more other locations on the display screen 14.
FIG. 2B illustrates another exemplary embodiment of this invention. In this embodiment the user can write on the display 14 (or speak depending on the specifics of the user interface) a word or phrase such as the generic word: “Dog”. The image data corresponding to the entered word or phrase can be sent to the host system 40 where handwriting recognition software (or speech recognition software) stored in the memory 24 recognizes the written word or phrase. In response the memory 24 or the database 32 can be searched using the generic word “Dog”. Assuming that search results are generated then possibly multiple instances of dog images 64 can be presented to the user on the display 14 enabling the user to select one or more of the images. At this point the user could also save a specific displayed dog image instance using the procedure depicted in FIG. 2A, and could rename the saved specific instance and subsequently recall and redisplay the saved specific instance of the dog image.
In the embodiment of FIG. 2B the search can be made of various dog images saved by one or more users according to the procedure of FIG. 2A. Alternatively the search can be conducted via the network 30 to locate one or more dog images from one or more Web-based image repositories. For example, the user could be presented with a plurality of clip-art images that are retrieved from the Web and that correspond to the generic category: ‘Dog’.
It should be pointed out that the user may be enabled to specify a search location for conducting the search. The search location could be, by example, a site associated with a brand, or a social networking site. The returned instance or instances of the search result could be a static image, or a video clip, or a link to a video such as a documentary produced by some third party as several non-limiting examples. If a video clip or video is returned it can be streamed from the host system 40 to the display system 12 for viewing on all or a portion of the display 14.
In accordance with a further aspect of the embodiments of this invention certain capabilities of the pens 15 can be leveraged to enhance the user interface capabilities. For example, the use of a ‘blue’ pen can be interpreted to save the image content 60A to a drop box, the use of a ‘red’ pen can be interpreted to save the image content 60A to the cloud, while the use of a ‘green’ pen can be interpreted to save the image content 60A to one or more of the connected devices 19. In other embodiments the use of the ‘green’ pen to write a word or words on the display 14 can be interpreted as a command to retrieve a file identified by the word or words. In other embodiments the command(s) can be gesture-based where, as non-limiting examples, a user drawing a line from a drawn image towards the edge of the display can be interpreted as a command to ‘save-off’ the image to storage and to prompt the user to enter a descriptive (file) name for the saved content, while the user drawing a line from the edge of the display 14 to a written word or words can be interpreted as a command to retrieve a stored file having a name matching the written word or words.
In all of these various examples the content is saved off, mapped, and indexed as items that can be recalled at a later time. At a later time the user writes or draws on the display 14 at a particular location and the host system 40 retrieves/pulls up the matched content onto the display 14 at the location where the user is writing/drawing. For example, the user starts to write the name of an image file: “mydog.gif”, and the host system 40 replaces the written text/symbols with the corresponding retrieved image as in FIG. 2A. As another example the user writes a generic category (as text) or draws a generic image on the screen: “DOG”, and the host system 40 displays to the user the various images in that generic category giving the user the opportunity to select a pertinent image (as in FIG. 2B). As another example the user writes a brand name on the IPD or the name of a social networking site, as two non-limiting examples, and the host system 40 creates an embedded object that is linked to a Web site associated with the brand name (e.g., ‘www.brandname.com’) or with the social networking site (e.g., ‘www.social network.com’).
In general, the above mentioned mapping and indexing can be, by example, user-specific (tied to the identity of the user or users); content specific (tied to the type of content on the display); and/or context-specific (tied to one or more of the time, date, location and/or condition(s) under which the content is saved.)
Once established, meta-data can be used to retrieve context from any number of possible locations, including local or remote memory and/or from a location reachable via the web or any networked content source.
The various non-limiting examples of embodiments of this invention encompass an automatic discovery of a mapping (e.g., user-specific, content-specific, context specific) on the display 14 and/or associated connected devices 19 (e.g., laptops or PCs via Bluetooth, etc.). If no mapping is discovered then the user is allowed and can be prompted to create a mapping/index.
Various methods for content typing and look-up include using the mapping system, which forms a part of the program 26, to automatically create content associations. If no mapping exists a look-up by filename (referencing files saved off of the system or connected devices 19) can be attempted. In addition MIME (discussed below) or some equivalent mechanism can be used to determine content type (e.g., use a file header to look-up content-id and content-type). It is also within the scope of the embodiments of this invention to find matching images based on tags or keywords. Furthermore, a file system may be presented to the user to enable the user to navigate to a folder and file of interest.
In general, the above-mentioned mapping and indexing can also be, for example, based on at least one of a recognition of information conveyed by at least one marking made by the user, pixel locations on the display screen that correspond to the at least one marking and pixel attributes including color, such as a color associated with a particular one of the pens 15.
As was noted above there are various methods that can be used for determining content type and look-up. For example, the mapping system that forms a part of the program 26 of FIG. 1 can be used create content associations. If there is no mapping created then the system 40 can perform a look-up by the file name by referencing those files saved to the memory 24, and/or the database 32, and/or to some external (e.g., cloud) storage medium, and/or to one or more of the connected devices 19. The mapping system can utilize, for example, MIME types (e.g., see N. Freed, N. Borenstein, Request for Comments (RFC): 2046, November 1996: “Multipurpose Internet Mail Extensions (MIME) Part Two: Media Types”) to determine content type by performing, for example, a file header to look-up the content-id and content-type. The host system 40 can also find matching images based on tags or keywords supplied by a user. In these various embodiments a file system can be presented to the user on the display 14 who can then navigate to a folder and file of interest. In various non-limiting examples of use cases the user is enabled by to retrieve a specific file, or to retrieve a generic category of content by interacting with the user interface of the display system 12.
The exemplary embodiments of this invention provide an ability to recall content saved from a display system based on tags/metadata. The use of these embodiments can benefit at least display system providers as well as software application providers having access to application program interfaces (APIs) and/or other programming interfaces for the display system 12 to enable the rendering of the retrieved content.
