Abstract:
An imaging apparatus includes an image acquisition mechanism configured to acquire an image by imaging a subject to output an acquired image; an acquired image characteristic amount extraction mechanism configured to extract a characteristic amount of the acquired image acquired by the image acquisition mechanism; and a retrieval mechanism configured to retrieve images of which the characteristics are identical or similar to the characteristics of the acquired image from other images other than the acquired image using the characteristic amount extracted by the acquired image characteristic amount extraction mechanism.
Abstract:
An interactive application for execution on a handheld display device having an image sensor, a transceiver and a touch-sensitive screen. The interactive application is configured to operatively control the device so as to perform the steps of: determining interaction data using image data captured by the image sensor, the image data being captured by imaging a printed substrate containing printed content; sending the interaction data to a computer system, thereby causing the computer system to retrieve display data corresponding to the printed content; receiving the display data from the computer system; and displaying content based on the received display data. The touch-sensitive screen enables interaction with the displayed content.
Abstract:
A method of controlling audio playback using a handheld display device having a touch-sensitive screen and a transceiver for sending and receiving digital information. The method comprises the steps of: imaging an area of a printed substrate and generating image data using an optical sensor, the printed substrate containing printed content associated with audio; determining interaction data using the image data, the interaction data identifying a substrate identity; retrieving audio data associated with said printed content; displaying, on the touch-sensitive screen, display information identifying the audio together with a static element for controlling audio playback; and controlling audio playback by interacting with the static element via the touch-sensitive screen.
Abstract:
An interactive document retrieval device that has a processor for receiving first indicating data identifying a page identity and one or more locations on a first interactive document having a corresponding page description stored in one of a plurality of servers and, a print engine having a printhead. The processor is configured to use the page identity contained in the first indicating data to determine a network address of a server handling the page description corresponding to the first interactive document, send second indicating data to said network address identified using the page identity, said second indicating data being based on the first indicating data, receipt of said second indicating data by said server initiating a request for a second interactive document such that the processor receives response data corresponding to the second interactive document, and instruct the print engine to provide the second interactive document via the printhead.
Abstract:
A method of playing video using a handheld display device having a touch-sensitive screen and a transceiver for sending and receiving digital information. The method comprises the steps of: imaging an area of a printed substrate and generating image data using an optical sensor, the printed substrate containing printed content associated with a video; determining interaction data using the image data, the interaction data identifying a substrate identity; retrieving video data associated with the printed content; and playing, on the touch-sensitive screen, the video based on the retrieved video data.
Abstract:
A system is provided for verifying the validity status and/or authenticity information of a secure document. The secure document has user discernable information and a plurality of tags printed thereon. Each tag contains coded data encoding an identity of the document and a location of that tag on the document. The system has memory for recording a correspondence between the identity of the secure document and validity status and/or authenticity information relating to the secure document, a receiver for receiving data from a sensing device, and a processor for verifying the validity status and/or authenticity information of the secure document using the received data and the recorded correspondence. The data received from the sensing device identifies the document identity and a position of the sensing device relative to the document, and is generated by the sensing device sensing coded data contained in at least one tag.
Abstract:
An electronic pen for interacting with a substrate having coded data disposed thereon. The pen comprises: an image sensor for sensing the coded data when the pen is used to interact with the surface; a cartridge having a nib for contacting the surface; a retraction mechanism for slidably moving the cartridge between a retracted position and an extended position; a force sensor cooperating with the retraction mechanism; and a processor configured to generate indicating data indicative of the interaction with the substrate. The image sensor is configured to sense the coded data only when the force sensor detects that the nib is in contact with the substrate.
Abstract:
A method of retrieving a document from a database of hierarchical electronic document versions is disclosed. Each document version is associated with a unique document instance. In the method a search form is printed. The search form includes a search instruction input field relating to at least one parameter of a search to be carried out within the database and a plurality of coded data tags. Each coded data tag encodes a location of that coded data tag on the search form. The coded data tags are sensed by a sensing device as the sensing device is used to handwrite at least one search term on the search form. Data representing the parameter and the at least one search term is generated, with the data representing the at least one search term being generated from the locations of the coded data tags. Next, a search is carried out within the database based on the at least one search term and parameter in order to identify document versions. A results form is printed, with the results form containing data representing the document versions identified in the search and coded data tags. By sensing one or more coded data tags on the results form, the document version associated with the coded data tag sensed on the results form is retrieved and printed.
Abstract:
A system for enabling user interaction with computer software. The system includes a computer system that determines information and an identity, which are at least partially indicative of a text field. The computer system then determines a layout defining an arrangement for coded data indicative of the identity and information, and transfers print data to a printer to thereby cause the printer to print a form by printing the coded data and the information. The coded data is printed to be substantially coincident with the information such that when a sensing device is placed in an operative position relative to the information, the sensing device can sense the coded data and generate indicating data at least partially indicative of the text field.
Abstract:
An image is shot by an electronic camera using a convenient operation. Shot images are recorded into a directory corresponding to a user by shooting date and/or event. When a print-out mode is selected, a plurality of thumbnail images are displayed on the camera display, and when a single click is made by an undepicted pen on a specified thumbnail image, the display color of the thumbnail image is changed. Furthermore, when another click is subsequently made, the display color of all the thumbnail images included in the same event as that of the first designated thumbnail image is changed. Subsequently, when another click is made, the display color of all the thumbnail images of the same shooting date is changed, and when another click is subsequently made, the display color of all the thumbnail images included in the same directory is changed. Furthermore, on a specified display screen, when an execution key is pressed, the thumbnail images of which the display color is changed are printed.
