  • Patent number: 9715738
    Abstract: Conventionally, when an input operation is recognized based on a three-dimensional measurement of user's hands, it was difficult to discriminate whether a plurality of detected hands is a pair of hands of a user or a plurality of users. An information processing apparatus according to the present invention includes an image acquiring unit configured to acquire information about an image capturing a space on an operation surface, a position identifying unit configured to identify the position where each of a plurality of objects to be used for an operational input has entered into the space based on information about the acquired image, and an association unit configured to identify a combination of a plurality of objects based on the position identified for each of the plurality of objects and associate the combined plurality of objects with each other.

  • Patent number: 9398182
    Abstract: There is provided an information processing apparatus that can improve operability for reading a reading target including a plurality of objects. In the information processing apparatus, when the reading target placed on a reading plate on which a plurality of objects can be placed is read, a completion level of the reading target including one or more objects placed on the reading plate is determined based on an image obtained by an imaging unit that captures an image of the reading plate from above. A timing of executing the reading of the reading target is controlled based on the completion level of the reading target determined by a determination unit.

  • Patent number: 7929770
    Abstract: A handwriting processing apparatus and method effective for search of, e.g., a document file including handwriting is provided. When a handwriting characters are input to a coordinate input unit as a search key, a corresponding character in a dictionary is recognized for each of the handwritten characters, a search unit searches for a text code stored in a document file storage unit based on a text code of the corresponding character if the corresponding character is recognized and the search unit searches for handwriting trail data stored in a handwriting trail storage unit based on a handwriting trail of the handwriting character if the corresponding character is not recognized, thereby finding a desired document file.

  • Patent number: 7925062
    Abstract: Signature data of a handwritten signature input to a signature authentication device is analyzed to determine whether to register the signature based on the characteristics of the stroke shape of the signature. If the signature registration is denied, a response message for making the signature registerable is displayed according to the way in which the signature is written. At least one of cumulative angle changes in the locus of the signature, fluctuation in the speed at which the signature was written, fluctuation in the size of the characters included in the signature, and fluctuation in the center positions of the characters included in the signature is used as the determination criterion.

  • Publication number: 20090259952
    Abstract: UI widget content includes reference information by which its own UI widget refers to a child UI widget, and a description of an initial-focus designation for designating which of its own UI widget and child UI widget will have initial focus. A self-UI widget is generated, a child UI widget associated with the self-UI widget is generated based upon the reference information, and a UI widget hierarchy is thus built. A path is followed from a root of the UI widget hierarchy to a child UI widget designated by the corresponding initial-focus designation information. When a UI widget for which a child UI widget has not been designated in the corresponding reference information is retrieved, it is determined that this UI widget is the UI widget having the initial focus.

  • Patent number: 6697524
    Abstract: An information processing method and apparatus which uses a memory storing stroke data forming one character together with respective stroke order information to display each stroke data based on the stored stroke order information at an arbitrary speed. In addition, a display speed changing instruction is input into the apparatus and the display speed of the stroke data is changed in response to the display speed changing instruction. In addition, stroke data stored in correspondence to the stroke order information of an input stroke order number is read from the memory and displayed. Further, the stroke data can be displayed under different display conditions such that the stroke order information stored in correspondence to the stroke data can be distinguished from each other.

  • Patent number: 6671403
    Abstract: Two different recognition processing units respectively perform a plurality of different recognition processing operations for the pattern to be recognized input from a character input unit, and acquire a plurality of recognition candidates and recognition scores. An accuracy calculation unit converts the recognition scores obtained by the two recognition processing units into accuracies based on a scale common to the plurality of different recognition processing operations using parameters stored in a parameter storage unit. A determination unit generates a recognition candidate sequence by determining the order of the recognition candidates obtained by the two recognition processing units on the basis of the accuracies converted by the accuracy calculation unit.
