The system is implemented by providing a system that implements selecting a selected area of a displayed object, and projecting a brush directly onto a surface of the selected area.

Abstract: Techniques are provided for broadcasting history or coarse representations or both of stroke media and other media. Levels are created for media, and the levels are periodically broadcast. The levels segment the media and allow the media to be examined with details that range from coarse to fine or examined with varying importance or both. The periodic broadcast of the levels provides history of the media. In particular, for stroke data, levels of detail are determined through a certain method. Each level of detail is periodically broadcast. The levels of detail may be shown by themselves or combined at a receiver to create segmented views of the stroke data. A user can select a coarse view of the stroke data to quickly see the stroke history. Additionally, techniques are provided for quickly and repeatedly accessing data elements in already existing data structures. Generally, a description is created that describes data elements in a preexisting data structure.

Abstract: A face recognition system and method project an input face image and a set of reference face images from an input space to a high dimensional feature space in order to obtain more representative features of the face images. The Kernel Fisherfaces of the input face image and the reference face images are calculated, and are used to project the input face image and the reference face images to a face image space lower in dimension than the input space and the high dimensional feature space. The input face image and the reference face images are represented as points in the face image space, and the distance between the input face point and each of the reference image points are used to determine whether or not the input face image resembles a particular face image of the reference face images.

Abstract: A raster center control circuit for a CRT-type display device that automatically determines a correct horizontal center position of a raster, regardless of a horizontal sync frequency input from a video card. The raster center control circuit includes a horizontal deflection circuit, electrically connected to a horizontal deflection yoke, to supply the horizontal deflection yoke with a parabolic wave signal used to determine a horizontal center position of the raster. A memory device stores predetermined values for raster control according to horizontal sync signal frequencies. A microprocessor determines a frequency of a horizontal sync signal and generates a raster control signal by converting one of the predetermined values stored in the memory device into a raster control signal according to the predetermined frequency.

Abstract: A user can selectively engage some part or all of the haptic display of a haptic interface device to produce an enhanced interaction with an environment with which the user interacts using the haptic interface device. Further, the haptic interface device can be implemented so that the part of the haptic display that is engaged can be engaged to varying degree. The degree of engagement with the haptic display (together with whether part or all of the haptic display is engaged) determines the manner in which the haptic display is experienced by the user. The selective engagement with the haptic display is enabled by adding a haptic clutch model to the underlying haptic model used to produce the haptic display, the haptic clutch model engaging some part or all of the haptic model in response to user input. The addition of a haptic clutch model to the haptic model used to produce a haptic display provides a richer user interaction than is provided by a haptic display produced by the haptic model alone.

Abstract: An image projection system is provided for generating an energy efficient output representative of a desired input image. The image projection system includes a light source positioning device for directing the light from a light source onto a spatial light modulator. An image source provides the desired image to the spatial light modulator and also image information to a light source position controller for coordinating the light source positioning device, such that the light from the light source impinges substantially only the area of the spatial light modulator which contains the desired image. In particular, the controller actuates the light source positioning device by using a predefined scan that corresponds to the desired image. The spatial light modulator modulates the light with the desired input image and generates an output representative of the desired image.

Abstract: A method for encoding handwritten symbols operates upon penstroke data received from a device capable of sampling a stylus position at discrete intervals. Each handwritten symbol is segmented into an ordered sequence of discrete strokes. An arc length and initial and final tangent angles are evaluated for each of these strokes. Each stroke is encoded in the form of a parameter set comprising position coordinates of the initial and final endpoints of the stroke, the arc length, and the initial and final tangent angles. In specific embodiments of the invention, the segmentation is based, in part, on properties of the handwritten symbol when it is expressed as a curve .phi.(s), wherein s represents arc length and .phi. represents the net turning angle.

After each full-frame iteration, the display pixel(s) corresponding to the best-fit templates are lighted.

Abstract: A method and apparatus for painting a digital picture using strokes of a digital brush is provided. The painting strokes entered by a user is handled using a "lazy" processing approach, in which a region of the picture being painted is updated according to the entered strokes only when that region is to be displayed for viewing. To this end, the painting strokes are recorded as an ordered sequence of painting steps. The digital picture being painted is partitioned into a plurality of individual regions, and each region is assigned an age which indicates a painting step in the ordered sequence that is last applied to that region. When a region becomes visible, i.e., it is displayed for viewing, the age of the region is checked, and all of the painting steps in the ordered sequence that are after the step indicated by the age of the region are then applied to the region so that it becomes up-to-date. The age of that region is updated accordingly.

Abstract: The computer-aided design system of the present invention is characterized in that a grasping force sensor 4 is mounted on that operating bar 3 at the front end of a manipulator 1 which is grasped directly and operated by an operator, and that the mechanical response characteristics of the system are varied on the basis of an output from the grasping force sensor 4. That is, the rigidity on the part of the manipulator is increased in response to a high grasping force during operation, since the rigidity of the hand is also high; and the rigidity on the part of the manipulator is decreased for a low grasping force during operation, since the rigidity of the hand is also low. In scenes in which a space on a computer screen defining no shapes is crossed by a cusor on the screen, a weak grip will lower the rigidity on the part of the manipulator, thus achieving the feeling of a smooth operation.

Abstract: In a digital display system including a stroke scanning mechanism, a method which comprises the steps of displaying symbology and increasing or decreasing the number of symbols stroke scanned, including the null symbol depending upon comparisons of actual stroke time to a predetermined stroke time limit. The symbology is initially displayed by stroke scanning. The actual stroke time for stroke scanning the symbology is measured. The actual stroke time is then compared with the predetermined stroke time limit to ascertain whether or not the time limit has been exceeded. If the stroke time limit is not exceeded and a null symbol is not present in the symbology stroke scanned, a null symbol is added. If the stroke time limit is not exceeded and a null symbol is present in the stroke scanned symbology, the number of symbols is increased. If the stroke timing limit is exceeded and a null symbol is present in the symbology stroke scanned, the null symbol is removed.

Abstract: A heads-up display (50) for an aircraft includes a digital image generator (52), a cathode ray tube (CRT) (54) and an optical system (56) which projects an image (58) formed on the CRT screen (54a) indicating the status of the aircraft operation onto a holographic mirror combiner (60) at a slant angle. The combiner (60) is transparent to the pilot's direct view through the aircraft windshield, but produces a reflected image of the CRT screen (54a) which is superimposed on the direct view. Pincushion distortion in the CRT (54) and geometric distortion caused by the slant projection angle are corrected by a digital look-up table memory (82, 84) which alters the initially orthogonal CRT horizontal and vertical deflection signals (Vh,Vv) in a manner which is the inverse of the distortion such that the image (58) on the combiner (60) as viewed by the pilot appears undistorted.

Abstract: The method of the present invention utilizes a microcomputer in combination with a CRT and a multiplicity of transducers for monitoring process parameters in the operation of a reciprocating device having a linear stroke. A profile of the process parameters including pressure and velocity are generated as a function of stroke length and time and are stored in a non-volatile memory and graphically displayed on the CRT as master traces for comparison with current data profiles. The velocity is calculated by dividing distance transversed with time or by use of a velocity position transducer.
