Wearable devices allow their users to communicate, track steps, monitor health, receive alerts and reminders, and to receive a host of other useful services. The wearable devices are also used to capture various data from the people sporting the wearable devices. Physiological data is among the data that can be captured. The physiological data, such as electrical characteristics of the skin, skin temperature, heart rate, and heart rate variability, can be augmented with pressure data. The pressure data is captured by a sensor built into a garment such as a glove. The pressure data is used to compensate the electrical characteristics of the skin. Other data such as blood sugar levels can also be collected. Together, the data can be used to monitor the health of the individual and to determine the individual’s mental states. Health monitoring supports rapid detection of health changes. A mental state can be an emotional state or a cognitive state. An emotional state indicates an emotion such as happiness or sadness. Cognitive states include concentration, confusion, disappointment, cognitive overload, boredom, exploration, confidence, trust, satisfaction, etc. Determination of the individual’s mental states supports business objectives. The determined mental states help gauge an understanding of an individual and how that individual responds to business products such as an advertisement, a store, a web site, a movie, a movie trailer, a product, a computer game, a video game, or food.
