Slate has a story about computer tutors that analyze students’ emotions using various tools to help them learn:
Researchers have found ingenious ways to identify these emotions in students—for example, the Posture Analysis Seat. This is a chair equipped with pressure sensors on its seat and back, allowing it to monitor the way learners are arranging their bodies. A student leaning forward is likely exhibiting interest and engagement; a student lolling back is apt to be bored or disengaged.
Then there’s the Pressure Mouse, a computer mouse that can detect how much pressure a user applies when clicking. Researchers have manipulated the level of frustration users feel (by employing “a frustration-inducing online application form,” of course) and have found that the more vexed users become, the greater the pressure they exert on the mouse. (Disclosure: The Pressure Mouse is a project of Arizona State University; ASU is a partner with Slate and the New America Foundation in Future Tense.)
