Abstract: A computer system includes a computer processor, an operating system operative in connection with the computer processor, and a display responsive to the operating system. The system also has a pointing device that includes a position sensor and a tactile actuator. A pointing device driver is responsive to the position sensor, and the tactile actuator is responsive to the pointing device driver. A general-purpose application is responsive to the pointing device driver and to the operating system and in communication with the display, and the pointing device driver is also responsive to the general purpose application. The system further includes a profile that maps region changes associated with material displayed on the screen to tactile signals to be sent to the tactile actuator.

Abstract: Provides a system for detecting an intersection between more than one panoramic video sequence and detecting the orientation of the sequences forming the intersection. Video images and corresponding location data are received. If required, the images and location data is processed to ensure the images contain location data. An intersection between two paths is then derived from the video images by deriving a rough intersection between two images, determining a neighborhood for the two images, and dividing each image in the neighborhood into strips. An identifying value is derived from each strip to create a row of strip values which are then converted to the frequency domain. A distance measure is taken between strips in the frequency domain, and the intersection is determined from the images having the smallest distance measure between them. The orientation between the two paths may also be determined in the frequency domain by using the phases of signals representing the images in the Fourier domain or performing a circular cross correlation of two vectors representing the images.

Abstract: Video recordings of meetings and scanned paper documents are natural digital documents that come out of a meeting. These can be placed on the Internet for easy access, with links generated between them by matching scanned documents to a segment of the video referencing the scanned document. Furthermore, annotations made on the paper documents during the meeting can be extracted and used as indexes to the video. An orthonormal transform, such as a Digital Cosine Transform (DCT) is used to compare scanned documents to video frames.

Abstract: A media browser, graphical user interface and method for browsing a media file wherein a user selects at least one feature in a media file and is provided with information regarding the existence of the selected feature in the media file. Based on the information, the user can identify and playback portions of interest in a media file. Features in a media file, such as a speaker's identity, applause, silence, motion, or video cuts, are preferably automatically time-wise evaluated in the media file using known methods. Metadata generated based on the time-wise feature evaluation are preferably mapped to confidence score values that represent a probability of a corresponding feature's existence in the media file. Confidence score information is preferably presented graphically to a user as part of a graphical user interface, and is used to interactively browse the media file.
