The U.S. Company Exmocare has developed a novel wristwatch, which is capable of monitoring many physiological signals. The Exmocare wristwatch monitors your heart rate, heart rate variability, movement and galvanic skin response, all of which the watch uses to determine how you're doing, specifically emotionally. If something's too outside the norm, the watch can report the condition to a loved one or caretaker over email, SMS or IM. It's primarily designed for elderly patients, and will be hitting the market early 2008.

When the Exmocare watch is worn over a period of time, it learns to recognize the wearer's baseline physical state, This allows the watch to analyze various changes by comparing them to the individual's normal state. By recognizing the context, the device can produce more accurate reports on the person's feelings. One can decide who receives the monitored information as well as what information they will receive. User-configurable alerts enable the wearer to choose how others will be notified in case something is wrong (by email, SMS, or instant messaging). When something happens to the wearer, the watch sends a signal to a PC. The PC passes the information through the Internet, and from there the caregiver, friend, or relative can receive the alert even to their cell phone.

By notifying the wearer and the caretakers of even the slightest physiological changes, the watch can act as a preventative early warning system. Exmocare draws attention to our body's warning signals, helping us to make necessary lifestyle changes and receive the support we need. This unique watch can also be used to monitor people with chronic illnesses and help manage personal fitness and weight loss.
