Knowra Smartwatch Smartwatch A wrist-worn computer that combines timekeeping with functions such as notifications, health tracking, and app access. It connects to other devices and uses sensors to interact with its wearer and surroundings.
Wearable technology : Electronic devices designed to be worn on the body and used during everyday activities. Smartwatches are a prominent wrist-worn form of this broader class.
Heart rate monitor : A device or system that measures and displays a person's heart rate. Wrist optical sensors let watches track pulse during rest and exercise.
Fitness tracker : A wearable device focused mainly on monitoring physical activity and health-related measurements. It often offers fewer general-purpose apps and interactions than a smartwatch.
Digital health : The use of digital technologies to support health services, monitoring, research, and self-care. Smartwatch measurements make consumer wearables a visible part of this broader domain.
Wearable sensor accuracy : The degree to which sensors worn on the body produce measurements close to the quantities they aim to measure. Motion, fit, skin, and activity conditions can affect smartwatch readings.
Accelerometer : A sensor that measures acceleration and changes in motion along one or more axes. It detects movement used for activity estimates, gesture controls, and step counts.
Step counting : The estimation of walking or running steps from movement data. A watch's motion sensors turn everyday movement into an activity count.
Traditional watch : A wrist-worn timepiece that displays time through mechanical or electronic timekeeping rather than general-purpose computing. Its simpler function can provide longer service without charging or software updates.
Consumer health informatics : The study and practice of using information technology to help people manage health and healthcare. Watches give individuals continuous streams of personal health data to interpret.
Medical device regulation : The rules governing the safety, effectiveness, and marketing of devices intended for medical use. Health features may face different requirements depending on their claims and intended use.
