摘要： A safety device for a cantilevered beam pivotally mounted adjacent one end thereof to a support surface is adapted to bridge the beam and the support surface and is structured so that when coupled to the beam and support surface, the safety device maintains the beam in a substantially fixed cantilevered condition until a downward force exceeding a threshold is applied to the beam and thereafter controls downward pivoting of the beam.

摘要： A method of inhibiting a subject's eyes from being exposed to projected light when the subject is positioned in front of a background on which an image is displayed comprises capturing an image of the background including the displayed image, processing the captured image to detect the existence of the subject and to locate generally the subject and masking image data used by the projector to project the image corresponding to a region that encompasses at least the subject's eyes, the image data masking compensating for differing camera and projector viewpoints.

摘要： An apparatus for detecting a pointer within a region of interest includes at least one pair of imaging devices. The imaging devices have overlapping fields of view encompassing the region of interest. At least one light source provides illumination across the region of interest and is within the field of view of at least one of the imaging device. A filter is associated with the at least one imaging device whose field of view sees the light source. The filter blocks light projected by the light source to inhibit the imaging device from being blinded by the projected light.

摘要： A touch system includes a reference frame, and at least two cameras having fields of view that overlap within the reference frame. The position of an object relative to the reference frame is determined from captured images of the object based on triangulation. The fields of view of the at least two cameras are rotated with respect to the coordinate system of the reference frame to define offset angles. The touch system is calibrated by: capturing an image of the object using each the at least two cameras at least one location within the reference frame; and for each location: determining the position of the object within each image, the position of the object within each image being represented by an angle φ, the angle being equal to the angle formed between an extremity of the field of view extending beyond the reference frame and a line extending from the camera that intersects the object within the image; and mathematically calculating the offset angles of the at least two cameras based on the angle determined for each image and the position of the at least two cameras relative to the coordinate system assigned to the reference frame.

摘要： A method of ordering visual objects presented on a display includes comparing visual objects to be placed in an overlapping condition and determining from the comparison the order in which the visual objects are to be placed. The visual objects are re-ordered and placed in the overlapping condition in accordance with the determination. Methods of creating connecting links joining source and destination visual objects as well as overlapping object and object-connecting tools are also provided.

摘要： A system for detecting contact on a display is provided. The system comprises a planar medium associated with the display and includes at least one edge facet and opposing surfaces. The system also includes one or more optical sources operatively coupled to the at least one edge facet for transmitting an optical signal into the planar medium such that the transmitted optical signal is totally internally reflected between the at least one edge facet and opposing surfaces. An optical sensing device is positioned to substantially face at least a portion of the edge facet and adapted to detect at least one object contacting a first surface of the opposing surfaces. The optical sensing device is operative to detect a portion of the optical signal emitted from the first surface at a location corresponding to the object contacting the first surface.

摘要： A method of calibrating an interactive touch system includes moving a pointer along at least one path on a touch surface over a calibration image presented on the touch surface. Pointer coordinates are generated generally continuously during the tracing representing pointer contact locations on the touch surface. The coordinate system of the touch surface is mapped to the coordinate system of the calibration image using the pointer coordinates and the calibration image.
