Sorry -- it's in my original question, from the statute (here https://www.law.cornell.edu/cfr/text/29/801.2)

"The term lie detector means a polygraph, deceptograph, voice stress analyzer, psychological stress evaluator, or any other similar device (whether mechanical or electrical) that is used, or the results of which are used, for the purpose of rendering a diagnostic opinion regarding the honesty or dishonesty of an individual. Voice stress analyzers, or psychological stress evaluators, include any systems that utilize voice stress analysis, whether or not an opinion on honesty or dishonesty is specifically rendered"

Yes, sorry... I'm not responding to your original question, I'm responding to the oversimplification,

> Lying is a behavior, and cheating is dishonest.

I'm aware of the definition.

The problem is that it depends on whether mouse movements are being used to detect psychological stress or whether they are used to detect that someone is cheating by flipping to another browser window or talking with someone in a chat window.

You raise a good point that my oversimplification obscured.
