  • Publication number: 20170018072
    Abstract: An index detecting section detects an index in a physical space, from a captured image obtained by an imaging apparatus. An erroneous-detection prevention processing section performs erroneous-detection prevention processing, based on information relating to image coordinates of a detected index. An image output section outputs, to a display device, an image having been subjected to the erroneous-detection prevention processing. This prevents an image displayed on the display device from being mistaken for a real index when the display device is in the field of view of the imaging apparatus.

  • Publication number: 20160279809
    Abstract: An information processing apparatus having a changed region detection unit performs a process that includes repeating a cycle. The cycle includes causing a projection unit to project a pattern, that includes light and dark portions, onto target objects, causing an image capturing unit to capture an image of the target objects while the pattern is being projected by the projection unit, and causing a holding unit to hold one of the target objects based on a captured image obtained by the image capturing processing. Based on a reference boundary position corresponding to a boundary between the light and dark portions in the pattern in the captured image obtained in a previous cycle and a target boundary position in the captured image obtained in a current cycle, the changed region detection unit detects a changed region with a change between the previous cycle and the current cycle.

  • Patent number: 9208530
    Abstract: At the time of using a haptic device to present to a user haptics which a first virtual object superimposed on the haptic device receives from a second virtual object superimposed on a real object, the user is enabled to touch within the second virtual object, regardless of the real object. Accordingly, the haptics received from the second virtual object is obtained using a first haptic event model of the first virtual object and a second haptic event model of the second virtual object, and while the first haptic event model corresponds to computer graphics information of the first virtual object, the shape of the first virtual object differs from that of the haptic device, such that instructions can be made regarding the inside of the real object, using the first virtual object.
