People use many kinds of wearable devices to monitor their health and wellbeing. Sensing is used to determine the physical condition, mood, emotions, and other information for an individual. A sensor can be built into a garment such as a glove. The sensor is worn by the individual and can pick up data relating to physiology, movement, and other factors. The data, such as skin temperature, heart rate, blood pressure, blood sugar, etc., is used to monitor the health of the individual and to determine the individual’s mental states. The individual’s health can be monitored to show, for example, that the individual is complying with a given therapy and that the therapy is working. Such health monitoring is useful to quickly detecting health changes and to adjusting therapies as required. The mental states are interesting and can include an emotional state or a cognitive state. An emotional state indicates an emotion such as happiness or sadness experienced by the individual. Cognitive states include concentration, frustration, confusion, disappointment, hesitation, cognitive overload, focusing, being engaged, attending, boredom, exploration, confidence, trust, delight, satisfaction, etc. Determination of the individual’s mental states has many uses in business applications. Determined mental states such as engagement, excitement, confusion, concentration, and worry, aid in the understanding of an individual and how that individual responds to an advertisement, walking through a store, interacting with a web site, a movie, a movie trailer, a product, a computer game, a video game, or consuming a food. Better consumer understanding leads to more sales.
