Abstract
A physical activity monitoring device includes a sensor array with one or more sensors configured to measure physical activity attributes of a user. A controller automatically determines time intervals where the user is actively engaged in a physical activity based on the physical activity attributes. The controller also automatically determines a type of physical activity the user in actively engaged in during the determined time intervals based on the physical activity attributes. A reporter outputs information regarding the type of physical activity to the user.
Claims18
A physical activity monitoring device, comprising:
- a sensor array including one or more sensors configured to measure physical activity attributes of a user while the user is wearing the physical activity monitoring device;
- a controller operable to:
- receive signal information from the sensor array;
- divide the signal information into overlapping segments;
- identify predetermined signal characteristics for each overlapping segment;
- analyze the predetermined signal characteristics for each overlapping segment using a supervised classifier trained to recognize if the user is actively engaged in a physical activity during the overlapping segment;
- automatically determine time intervals where the user is actively engaged in the physical activity using the physical activity attributes;
- and
- automatically determine a type of physical activity the user is actively engaged in during the determined time intervals using the physical activity attributes;
- and
- a reporter to output information regarding the type of physical activity.
A method of monitoring physical activity, comprising:
- measuring, with a sensor array including one or more sensors, physical activity attributes of a user wearing a physical activity monitoring device including the one or more sensors;
- automatically determining a set of time intervals where the user is actively engaged in a physical activity based on the physical activity attributes by:
- dividing signal information from the sensor array into overlapping segments;
- identifying predetermined signal characteristics for each overlapping segment;
- and
- analyzing the predetermined signal characteristics for each overlapping segment using a supervised classifier;
- using the supervised classifier to automatically determine a type of physical activity the user is actively engaged in during the determined time intervals based on the physical activity attributes;
- and
- outputting information regarding the type of physical activity.
A physical activity monitoring device, comprising:
- a sensor array including an accelerometer configured to measure physical activity attributes of a user wearing the physical activity monitoring device;
- a controller operable to receive acceleration signal information from the sensor array and to automatically determine time intervals where the user is actively engaged in a physical activity by:
- dividing the signal information into overlapping segments;
- identifying predetermined acceleration characteristics for each overlapping segment;
- and
- analyzing the predetermined acceleration characteristics for each overlapping segment using a supervised classifier trained to recognize if the user is actively engaged in the physical activity during the overlapping segment;
- the controller further operable to automatically determine a type of physical activity the user is actively engaged in during the determined time intervals using the physical activity attributes corresponding to the determined time intervals;
- and
- a reporter to output information regarding the type of physical activity.
