Abstract: A guided tour of some portion of the World Wide Web (WWW) works as part of an ordinary web page, can be served by any web server, and can be used by web browsers without additional software. The system guides a user through a tour by displaying in sequence actual web pages in the tour along with a corresponding teaching web page. The teaching web page includes educational information about the current web page. The tour includes commentary, allowance for side trips, true visiting of the tour pages, not mere copies, maps, and "static" (user clicks for next page) and "dynamic" (a timer controls how long a tour page is on-screen) tours.

Abstract: A system determines display durations of each of a plurality of images in a presentation based on a respective amount of the information content in the image, the greater the information content the longer the display time. There are various techniques for determining the information content of each of the images. For example, the system determines for each image the number of pixels at each of a multiplicity of respective pixel levels and the total number of pixels at one or more pixel levels for which the respective number(s) of pixels are significantly larger than the numbers of pixels at the other pixel levels. The pixels represented by these one or more pixel levels likely represent background or other mundane information. Consequently, only the pixels at the other values are considered as containing important information and their total number represents the total information content of the image.
