Embodiments leverage wireless data passively collected by access points of a school to correlate a student's behavior with respect to time and place. This data-driven approach can quantify student behaviors and objectively measure and track how students move and interact on campus. For example, if a student accesses a wireless router that is in the same physical location as a class on the student's schedule at the time the class takes place, the correlated time and place quantifies how the student behaves with respect to class attendance. The invention takes the sum of such interactions (e.g., attending classes, studying in the library, etc.) and produces a student engagement score (SES) for each student. The SES is evaluated to determine how student behaviors change over time (e.g., throughout a semester) and whether the student is trending to a low engagement score and thus “at-risk” of dropping out.

The system sums the workload value of the buttons pressed by the driver over a moving time window to determine the estimated driver workload.

In one method, a human user couples a computer readable media associated with a product to a computer. A computer program on the computer readable media checks for, and if need be, installs needed software. The program can then establish a connection over a network such as the Internet directly to the help assistance organization appropriate for the particular product or service. The computer readable media can include an indication of the particular product or service and/or the assumed preferred language of the purchaser of the product or service. The assistance request can be routed to a human assistant, who may be seated at a computer device. In a preferred method, the human assistant greets the request for assistance and the human user with a live, personal, updated video link carrying the assistant's voice and a video signal carrying the assistant's image to the computer of the help requestor. The assistant may obtain preliminary information from the human user, and begin rapidly to provide assistance in a 'face to face' virtual environment. Where the product involved is a computer related product, the human assistant may optionally view the same computer display as the human user and even manipulate the display to illustrate the performance of a particular software product.
