Psychophysiology studies how physiological signals like heart beats or skin conductance can reflect your state of mind. With wearable technologies signals can be used to continuously measure how people feel in their everyday life. In this talk, Joyce discusses how monitoring physiology can serve to make people more aware of what exactly is affecting their personal state of mind, for instance what causes stress. Taking personalization one step further, we can also use the psychophysiological signals in a closed loop in order to continuously adapt the user’s mood, e.g., through optimized music selection.

Joyce H.D.M. Westerink studied physics at Utrecht University (NL), and graduated in 1985. Since then, she joined Philips Research and specialized on topics involving human interaction with consumer products: visual perception of display devices, user-friendliness of home entertainment systems, sensory aspects of personal care products and psychophysiological aspects of user experience. Written output of her work can be found in some 40 articles in books and international journals, a Ph.D. dissertation (1991), and some 15 US patents and patent applications.
