In a dream world, the most obvious place to measure pressure as a factor of stress is in the devices they're already holding. Imagine a mouse that knows how hard you're squeezing it, or how hard you're pressing it. Wii may be closer to making this a reality. Same goes for the keyboard, and the chair they're sitting in. Pressure-sensitive devices could give you probably the most accurate information - but as someone mentioned you'd need a bunch of psychologists to interpret the results, and some kind of control test (do something easy) to know how much pressure was right for which people.
Some other things you could measure (I know you were looking for actual real-world devices, but I'm on a roll now =])...if you record your session, count the number of times they *sigh* during the pre-questionnaire, the tasks, then the follow up questionnaire. Count the number of times their legs move. Count the number of times they swing the mouse around or tap it with their fingers. All of these would probably work, with a PHD in the room =] -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Beck Tench Sent: Friday, November 02, 2007 8:09 AM To: [EMAIL PROTECTED] Subject: Re: [IxDA Discuss] frustation meter I'm thinking of those "test your strength" hand grip machines in arcades... squeezing seems a natural way to express frustration in the moment. (I have no idea how you'd rig this up.) Another idea, if frustration = pain in some way, what about an analog to a morphine drip? :) The user pushes a button everytime they feel frustrated, after so many presses (or at random) they receive a "hint." Ah, who knows... this gets complicated real fast and needs its own usability study to implement. Plus these things require a hand to operate and the user might need both hands for the task. I don't think a foot peddle reinforces the connection people have squeezing something in frustration or pushing a button in response to pain (even if they've only seen it on tv).
