Will wireless bracelet monitors be a useful way to assess student engagement?

Creators of an experimental bracelet, the Galvanic Skin Response monitor, want to use their device to assess student engagement in the classroom, and then use that information to inform teaching methods. The wireless-sensor technology, worn by a student, analyzes electrical impulses in the body to potentially determine whether a person enjoys a lesson or is bored by it. The GSR project has attracted the attention of education-focused organizations, including the Bill and Melinda Gates Foundation, which has pledged money to determine if the GSR is useful.
