Squeeze, rock, and roll; can tangible interaction with affective products support stress reduction?

Affective computing focuses on the interpretation of users emotions via physiological and behavioral inputs. Irrelevant gestures with a pen were found to increase when users were given a mentally demanding task. Accordingly, an embedded tangible interface was developed which afforded and measured a rolling behavior, and guided the user towards reaching a balanced state of movement. During informal evaluations users acknowledged how the device could contribute to stress reduction. Conclusion, tangible interfaces appear to offer a non-obtrusive means towards interpreting and reducing stress in the office work context.
