Abstract: The subject system measures and reports the use of a personal computer by a user through a log file. The log file includes entries corresponding to predetermined events and can report on the applications used and communication functions engaged in by the user. The log files from one or more computers may be assembled and analyzed in order to ascertain computer use habits for computer software, computer hardware and computer communications. The system may also be used to predict computer use trends and to represent computer use history.

Abstract: The method for conducting a survey of users of an information document site located on a computer network includes embedding computer program instructions into an information document located at the site, where the instructions invoke a survey program, launching the survey program when a user accesses the information document, and activating the survey according to offering criteria based upon either a random or systematic participant selection.
