TRACKING CALORIC EXPENDITURE USING A CAMERA - A simplified explanation of the abstract
This abstract first appeared for US patent application 18357089 titled 'TRACKING CALORIC EXPENDITURE USING A CAMERA
Simplified Explanation
The patent application describes a method for tracking caloric expenditure using a camera. The method involves obtaining face tracking data of a user, determining the user's step cadence based on the face tracking data, determining the user's speed based on the step cadence and stride length, obtaining device motion data from motion sensors, determining the grade of the surface the user is walking or running on based on the device motion data or face tracking data, and determining the user's energy expenditure based on the estimated speed, grade, and a caloric expenditure model.
- The method uses face tracking data to determine the user's step cadence and speed.
- Device motion data from motion sensors is used to determine the grade of the surface the user is on.
- The estimated speed, grade, and a caloric expenditure model are used to determine the user's energy expenditure.
Potential applications of this technology:
- Fitness tracking: The method can be used in fitness tracking devices or applications to accurately measure caloric expenditure during physical activities.
- Weight management: The technology can assist individuals in tracking their caloric expenditure to manage their weight and achieve their fitness goals.
- Rehabilitation: The method can be used in rehabilitation programs to monitor and track the energy expenditure of patients during exercises.
Problems solved by this technology:
- Accurate caloric expenditure tracking: The method combines multiple data sources, including face tracking and motion sensors, to provide a more accurate estimation of energy expenditure compared to traditional methods.
- Real-time monitoring: The technology allows for real-time monitoring of caloric expenditure, providing immediate feedback to users during their physical activities.
Benefits of this technology:
- Improved fitness tracking: The method provides a more accurate and comprehensive measurement of caloric expenditure, allowing users to better understand their physical activity levels.
- Personalized feedback: By tracking energy expenditure in real-time, the technology can provide personalized feedback and recommendations to users, helping them optimize their workouts and achieve their fitness goals.
- Enhanced rehabilitation programs: The method can assist healthcare professionals in designing and monitoring rehabilitation programs by accurately tracking the energy expenditure of patients during exercises.
Original Abstract Submitted
The enclosed embodiments are directed to tracking caloric expenditure using a camera. In an embodiment, a method comprises: obtaining face tracking data associated with a user; determining a step cadence of the user based on the face tracking data; determining a speed of the user based on the step cadence and a stride length of the user; obtaining device motion data from at least one motion sensor of the device; determining a grade of a surface on which the user is walking or running based on at least one of the device motion data or the face tracking data; and determining an energy expenditure of the user based on the estimated speed, the estimated grade and a caloric expenditure model.
