  • Patent number: 10510189
    Abstract: In an information processing system 1, an information processing apparatus 10 recognizes, when a user moves real bodies 120a and 120b arranged on a play field 19, the movement on the basis of, for example, an image taken by a camera 122 taking an image of the movement to interlock objects of corresponding characters 202a and 202b displayed on a display apparatus 16. In addition, when the user moves the characters 202a and 202b through an input apparatus 14, the information processing apparatus 10 transmits a control signal to the corresponding real bodies 120a and 120b to perform interlocking. When a situation in which interlocking between the real bodies 120a and 120b and the characters 202a and 202b is difficult occurs, an appropriate scenario is selected from the scenarios prepared in advance and realized, thereby maintaining the consistency.

  • Patent number: 10471343
    Abstract: A block set assembled by a user and an information processing device communicate with each other. The information processing device thereby obtains information on the structure of the block set. In addition, an object of a crane truck corresponding to the block set is displayed on a display device. Correspondences between joints and wheels and correspondences between movements are set. Thereby, when the block set is moved, the movement of the block set is reflected in the object on display. When the object is moved, the movement of the object is reflected in the block set by transmitting a control signal from the information processing device.

  • Patent number: 10477175
    Abstract: An image of a block or the like entering a space above a play mat is picked up by an image pickup apparatus, and an information processing apparatus detects and recognizes the block on the basis of a picture of the block in a picked up image and performs information processing. The play mat includes a play field that defines a detection space for the block, and a calibration chart including at least a plurality of regions of colors of different luminances. The image pickup apparatus adjusts an exposure time period, a gain value for each color component and a correction rule upon gamma correction on the basis of the picture of the calibration chart in the picked up image.

  • Patent number: 10279249
    Abstract: On a play field 20 set in real space, a target region 102 having the play field 20 as a bottom surface and having a predetermined height h is set virtually. A target region image that expresses a distance of the target region 102 from an imaging surface as a pixel value on an image plane is generated, and compared with a depth image corresponding to an actual captured image 100; thus, only images of blocks 3c and 3b inside the target region 102 are extracted as detection and tracking targets.

  • Patent number: 10192360
    Abstract: By extracting figures of a play field and a display apparatus from a taken image, the positional coordinates of the play field and a screen in a world coordinate system are obtained. Next, a virtual world is built such that the ground of the virtual world is positioned continually flush with the surface of the play field in a real world, on the opposite side of the real world with the screen in between in a virtual space defined in the world coordinate system. Then, a virtual viewpoint is placed at a position corresponding to the viewpoint of a user in a real space so as to generate an image with the virtual world projected to the screen on the basis of this virtual viewpoint as a display image.

  • Patent number: 10146332
    Abstract: A core information receiving section of an information processing device receives information related to the state of a core from a first block of a block set assembled by a user. A structure analyzing section identifies the shape, posture, and position of the block set on the basis of an image photographed by a camera and the information related to the state of the core. An information processing section performs predetermined information processing according to the shape, posture, and position of the block set or an operation on an input device by the user. A display processing section generates an image to be displayed as a result of the information processing, and outputs the image to a display device. A driving control section transmits a signal for controlling the operation of the block set.

  • Patent number: 10130883
    Abstract: An information processing device communicates with a block set assembled by a user, and thereby obtains information on the structure of the block set. In addition, a corresponding position setting screen including an image of an object corresponding to the block set is displayed on a display device. The user moves a joint of the block set which joint is desired to be associated, by for example bending and stretching the joint. Next, the user indicates a joint to be associated on a 3D object side in the image of the 3D object by a cursor, and performs a determination input. The joint of the block set and the joint of the 3D object are thereby associated with each other. The block set and the object are interlocked with each other bidirectionally by thus setting the corresponding positions of the block set and the object.
