摘要:
A system generates and arranges animation sequences of articulated characs for review and selection by a user. Motion of articulated characters is based upon input parameters, such as torques at joints of the character. The system can be used to select appropriate parameters to obtain desirable motion of the articulated characters. The system generates a set of input vectors containing parameters of the motion. The input parameters are then processed to determine animation sequences and corresponding output vectors. The output vectors include characteristics of the motion. The input vectors are selected to provide a dispersed set of output vectors. A large number of random input vectors can be generated and then culled to leave a dispersed set of output vectors. Alternatively, a set of randomly generated input vectors of a predetermined size are randomly perturbed, to further disperse the output vectors. The system includes an interface for representing the output vectors and animation sequences in a manner which is easily reviewable by a user. The output vectors are displayed so that positions represent distances between the output vectors. The user can then select specific output vectors so that the corresponding animation sequence is displayed.

A system generates and arranges animation sequences of particle motion foreview and selection by a user. Motion of particles in an animation sequence is based upon input parameters, such as creation point, creation rate, velocity, direction, and lifetime. The system can be used to select appropriate parameters to obtain desirable motion of the particles. The system generates a set of input vectors containing parameters of the motion. The input parameters are then processed to determine animation sequences and corresponding output vectors. The output vectors include characteristics of the motion. The input vectors are selected to provide a dispersed set of output vectors. A large number of random input vectors can be generated and then culled to leave a dispersed set of output vectors.

A computer-based system for automatic pagination and layout of yellow pagesor a commercial telephone directory uses a simulated annealing heuristic to refine a randomly determined candidate solution. The text and advertisements which are to be included in the yellow pages directory are ordered in two distinct data streams representing the order of text and the order of advertisements in the directory. The system determines a possible layout, called a candidate solution, by randomly setting parameters defining the pagination and layout. These parameters may include page breaks in the advertisement stream, column numbers for each advertisement, and an amount of padding or empty space to be added to each page. Once the parameters are set, the individual pages are laid out by putting the advertisements in the next available position in their assigned columns, and the text around the advertisements. The solution is scored based upon the guidelines for the format and layout of the yellow pages directory. The solution is then optimized using a simulated annealing heuristic, which utilizes small modifications or perturbations randomly made to the initial parameters of the candidate solution. The revised solution is scored and compared to the score of the prior solution. The revised solution is then kept according to a probabilistic formula relating the two scores. Through an iterative process of perturbations, scoring, and comparing, the candidate solution becomes optimized. The process is repeated multiple times for different initial candidate solutions, each of which is randomly determined. A best solution is then selected from all of the optimized candidate solutions.

Methods and apparatus are provided for accessing an experience journal which includes unstructured text items relating to a topic, such as a medical condition. The method is implemented in a computer system including a processor, a storage device, a video display unit having a display screen, and a user interface. The unstructured text items are stored in the storage device. Similarities among the unstructured text items are determined, and icons, one corresponding to each of the unstructured text items, are displayed on the display screen. The icons are positioned on the display screen relative to each other, such that the distances between icons are representative of the determined similarities among the unstructured text items. In response to user selection of one of the icons, the corresponding unstructured text item is displayed on the display screen.

A system for creating lighting for a photograph generates a large number ofmages based upon structures determined from the photograph and randomly selected light positions, types and directions. One or more photographs are analyzed to determine the three-dimensional structures in the photographs. These structures are represented as gray surfaces, to which lighting is applied. The images are culled to provide a set of images which best spans the lighting space represented by the large number of images. The culling process is iterative; at each iteration, the image which is most dissimilar from a nearest neighbor in the selected set is added to the selected set. The images are organized in a hierarchical structure. A user interface allows the user to review and select images in the hierarchical structure. The images selected by the user are combined to create a final image with composite lighting. The lighting specifications can be saved for future reference by the lighting system or other applications. The lighting of the gray surface images are used to modify the intensity of pixels in the photograph in order to change lighting in the photograph.

A system and method for creating lighting for an image generates a large number of images based upon randomly selected light positions, types and directions. The images are then culled to reduce the number of images to be reviewed by a user. The images are culled to provide a set of images which best spans the lighting space represented by the large number of images. The culling process is iterative; at each iteration, the image which is most dissimilar from a nearest neighbor in the selected set is added to the selected set. The images are organized in a hierarchical structure to ease review by the user. The hierarchical structure separates the images into multiple levels. At each level, the images are separated into sets of equal size. Each set includes images which are most similar. An average image from each set is picked as the visual representation for that set. In creating the hierarchical structure, a single image may or may not be included in different subsets. A user interface allows the user to review and select images in the hierarchical structure. The images selected by the user are combined to create a final image with lighting. The lighting specifications can be saved for future reference by the lighting system or other applications.

A method and system propagates only interesting sound information to a user who is otherwise acoustically isolated from sound. This is a task particularly useful for people that work in, or enjoy noisy environments, and are placed in a soundproof room, or are otherwise unable to detect critical sounds. By automatically detecting critical sounds, the user can be alerted by a signal generated in response to detecting the selected sound information.

A system for interactive manipulation of graphs by a user applies constraints to obtain a visually pleasing display. The user adds nodes and edges to the graph. Visual Organization Feature (VOF) constraints are then applied to the nodes. The system uses a generalized spring algorithm to apply the constraints. Springs are attached to selected nodes to which a constraint is to be applied. The length and the second end-point of each spring are set based upon the constraint which is to be applied. The system then determines by simulation at-rest positions for all of the nodes based upon the springs. As the user adds, changes or deletes VOFs or changes the positions of the nodes, the graph is automatically reconfigured based upon the constraints. A user interface in connection with the graph drawing system provides a display for the graph and selection buttons for applying the VOFs.

An interface is useful in browsing output vectors resulting from applying a transfer function to input data. The interface allows a user to explore effects of different parameter settings which make up the transfer function, particularly in connection with computer-generated and computer-modified images. The interface includes two portions, a central display panel and a surrounding area of a plurality of image displays. Thumbnail sketches of images corresponding to each of the output vectors are located in the central display panel to represent the relationships between the output vectors. The output vectors are processed to determine distances between them, and the distances are then projected to the two-dimensional display of the central display panel. The central display panel can be controlled to pan and zoom the display to review the thumbnail sketches. The user can then select different thumbnail sketches so that full-sized images are displayed in the plurality of image displays. The interface also has additional displays which can overlay the central display panel and the image displays. The additional displays represent information about the images or vectors. The input or output vectors corresponding to a specific image can be displayed. Alternatively, the image can be displayed in larger detail in an additional display.
