Sensor Journalism

I imagine an array that attempts to measure stress and exertion levels at different workplaces via pressure and heat sensors placed beneath mousepads. I believe that individuals who work in front of computers do in fact ‘take out’ some of their aggression or frustration on the devices, and this is (I hope) measurable via use of the mouse. Basically, what I want to see is if work related stress and how hard a user pushes down on his or mouse are at all related. These results, along with survey answers about work related stress should help to confirm or deny my theory.
