  • Patent number: 10171950
    Abstract: An improved system and method for defining an event based upon an object location and a user-defined zone and managing the conveyance of object location event information among computing devices where object location events are defined in terms of a condition based upon a relationship between user-defined zone information and object location information. One or more location information sources are associated with an object to provide the object location information. One or more user-defined zones are defined on a map and one or more object location events are defined. The occurrence of an object location event produces object location event information that is conveyed to users based on user identification codes. Accessibility to object location information, zone information, and object location event information is based upon an object location information access code, a zone information access code, and an object location event information access code, respectively.

  • Patent number: 9869438
    Abstract: A system for dynamically projecting a logo onto a surface includes a light source, moveable lenses, and an actuator. The light source emits light toward the surface. The lenses are positioned with between the light source and the surface, with each lens having multiple transparent portions configured to permit some of the emitted light to pass through the lens in a corresponding light pattern. Each corresponding light pattern forms a different part of the logo. The actuator moves the lenses with respect to the emitted light in response to a control signal to thereby cause projection of the logo onto the surface. A vehicle includes a body having a door, road wheels in contact with a road surface, and the system which projects the logo onto the road surface proximate the door. The controller may be programmed to execute a method for projecting the logo.

  • Patent number: 9465438
    Abstract: A low-cost tactile feedback mouse device for providing haptic feedback to a user for enhancing interactions and manipulations in a graphical environment provided by a computer. The mouse device includes a sensor device able to detect the movement of the mouse in the planar workspace. An actuator is coupled to the housing of the mouse and applies an inertial force in a particular degree of freedom, preferably along an axis perpendicular to the planar workspace, where the inertial force is transmitted through the housing to the user. The actuator outputs the inertial force preferably by linearly moving an inertial mass along the Z-axis. The output force is correlated with interaction of a controlled graphical object, such as a cursor, with other graphical objects in a graphical environment displayed by the host computer. The inertial force can be a pulse, vibration, texture force, or other type of force.

  • Patent number: 9207783
    Abstract: The synchronous optical pen electronic whiteboard system in the present invention introduces an image sensor with a global shutter, optical pen pulsing light-emission and synchronizing signal transmitter and receiver. The light pulsing of the optical pen and the exposure of the image sensor coincide by synchronizing signal so as to realize the object of increasing signal-to-noise-ratio. A synchronizing signal sender can be arranged in the optical pen and a synchronizing signal receiver arranged in a signal receiving device, or a synchronizing signal sender can be arranged in the signal receiving device and a synchronizing signal receiver arranged in the optical pen. The coincidence of light pulsing and the exposure can be realized in the two solutions, thereby realizing the object of the present invention. By using the solution of the present invention, the power consumption of the optical pen can be reduced effectively and the signal to noise ratio of the system can be effectively increased in the meanwhile.

  • Patent number: 8982050
    Abstract: An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. The pointing device captures images displayed by the computer, including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. Motion of the pointing device between the two frames is detected by relative motion sensors, and used to align the positions of the positioning targets in the captured images for those frames to improve the fidelity of the recovered positioning target following the subtraction.

Furthermore, the method comprises determining a finger gesture which corresponds to the finger movement using a lookup table having multiple preconfigured finger gestures based on the direction data.

  • Patent number: 8139059
    Abstract: Methods and systems for displaying an image as a virtual representation of an object based upon detected external light are described. An illustrative computer-implemented method includes steps of detecting the ambient light of an environment, such as a room, at a display surface. Data representative of the detected ambient light is processed to determine a direction of the detected light with respect to the display surface. An image is displayed on the display surface as a virtual representation of an object based upon the detected ambient light. Shadowing affects may be displayed to create the appearance that the virtual representation of the object casts a shadow on the display surface. Physical objects placed against or near to the surface of the display surface may also have images displayed on the display surface corresponding to shadows created by the ambient light.

  • Patent number: 8094975
    Abstract: Provided is an information processing system which has a plurality of tags, a tag reader, a digital-pen, and a server. The plurality of tags each hold a tag identifier. The tag reader reads the tag identifier held in each of the plurality of tags. The digital-pen reads location information, which identifies a location where handwriting is made on paper. The server keeps work record including information that associates the tag identifier recorded in the server in advance with the location on paper. When it is judged that the read tag identifier and a handwriting location identified by the location information are associated with each other, the server judges whether or not the read tag identifier matches the tag identifier recorded in advance that is associated by the work record with the handwriting location identified by the location information. The server outputs a result of the judging.

  • Patent number: 8009152
    Abstract: A refined coordinate detection method for a touch panel, which more finely measures coordinates of an object without increasing the number of infrared emitting/receiving elements, and an error correction method, which minimizes position detection errors caused by received optical level errors due to external environment or their inherent characteristics, are provided. In the detection method, received levels of infrared emitting/receiving elements corresponding to left and right ends of object are measured and stored and the levels and a maximum received level are compared to calculate the refined coordinates. In the correction method, a lower limit level at a position where infrared reception is most significantly impeded by object is calculated through a comparison calculation of maximum and minimum received levels and it is detected that an object is present at a position only when a lower limit level at that position is not greater than the calculated one.
