摘要:
A method for managing information displayed on a computing device includes automatically creating, using an application executed by a processor of the computing device, an interactive content display panel, wherein the interactive content display panel includes a graphical user interface element associated with HTML content. The interactive content display panel is displayed in front of all other windows displayed in a work area of a display of the computing device. The displaying includes automatically adjusting the size the interactive content display panel, based on updates to the HTML content, and automatically positioning the interactive content display panel in the display, based on the automatic adjustment of the size of the interactive content display panel and based on available space in the work area of the display.
摘要:
A method and apparatus for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries, or tracking of a cursor image on a screen by the subject through a known trajectory. One embodiment provides a method for tracking a user's eye gaze at a surface, object, or visual scene, comprising: providing an imaging device for acquiring images of at least one of the user's eves: modeling, measuring, estimating, and/or calibrating for the user's head position: providing one or more markers associated with the surface, object, or visual scene for producing corresponding glints or reflections in the user's eyes; analyzing the images to find said glints or reflections and/or the pupil: and determining eye gaze of the user upon a said one or more marker as indicative of the user's eye gaze at the surface, object, or visual scene.
摘要:
A twin-beam laser module has a housing having a first cylindrical space and a second cylindrical space, which are adjacent and parallel in axial direction to each other. A first laser assembly is directly secured inside the first cylindrical space to output a first laser beam, and an outer cylindrical casing is positioned inside the second cylindrical space. A second laser assembly is provided inside the outer cylindrical casing to output a second laser beam, and an adjustment apparatus adjusts the orientation of the outer cylindrical casing so as to align the first laser beam and the second laser beam to be parallel to each other.

摘要:
Apparatus and method for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries or the tracking of a cursor image on a screen by the subject through a known trajectory. One embodiment includes one uncalibrated camera for acquiring video images of the subject's eye(s) and optionally having an on-axis illuminator, and a surface, object, or visual scene with embedded off-axis illuminator markers. The off-axis markers are reflected on the corneal surface of the subject's eyes as glints. The glints indicate the distance between the point of gaze in the surface, object, or visual scene and the corresponding marker on the surface, object, or visual scene.

A gun accessory includes a main body having an upper surface having two sides, a first side wall and a second side wall extending upwardly from each of the two sides, first and second slide members provided on the first and second side walls, respectively, and a first locating hole provided adjacent the first side wall. The accessory also includes a first locating bar pivotably coupled to the first locating hole and having a first baffle and a first press plate, and a first elastic element provided between the first press plate and the main body to pivot the first press plate with respect to the main body, and in turn drive the first baffle to protrude above the upper surface of the main body.
摘要:
A system and method for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries or the tracking of a cursor image on a screen by the subject through a known trajectory. The preferred embodiment includes one uncalibrated camera for acquiring video images of the subject's eye(s) and optionally having an on-axis illuminator, and a surface, object, or visual scene with embedded off-axis illuminator markers. The off-axis markers are reflected on the corneal surface of the subject's eyes as glints. The glints indicate the distance between the point of gaze in the surface, object, or visual scene and the corresponding marker on the surface, object, or visual scene. The marker that causes a glint to appear in the center of the subject's pupil is determined to be located on the line of regard of the subject's eye, and to intersect with the point of gaze. Point of gaze on the surface, object, or visual scene is calculated as follows. First, by determining which marker glints, as provided by the corneal reflections of the markers, are closest to the center of the pupil in either or both of the subject's eyes. This subset of glints forms a region of interest (ROI). Second, by determining the gaze vector (relative angular or cartesian distance to the pupil center) for each of the glints in the ROI. Third, by relating each glint in the ROI to the location or identification (ID) of a corresponding marker on the surface, object, or visual scene observed by the eyes. Fourth, by interpolating the known locations of each these markers on the surface, object, or visual scene, according to the relative angular distance of their corresponding glints to the pupil center.
