Abstract
The present disclosure is directed to a device with enhanced human activity recognition. The device detects a human activity using one more motion sensors, and enhances the detected human activity depending on whether the device is in an indoor environment or an outdoor environment. The device utilizes one or more electrostatic charge sensors to determine whether the device is in an indoor environment or an outdoor environment.
Claims18
A device, comprising:
- a motion sensor configured to generate a motion measurement of the device;
- an electrostatic charge sensor configured to generate an electrostatic charge measurement of the device;
- and
- a processing unit configured to:
- perform context detection to detect the device is indoors or outdoors based on the electrostatic charge measurement;
- perform, subsequent to the device being determined to be indoors based on the electrostatic charge measurement, first human activity recognition to detect a first activity state of a user of the device selected from a plurality of indoor states based on the motion measurement, the first human activity recognition being performed without outdoor state detection;
- perform, subsequent to the device being determined to be outdoors based on the electrostatic charge measurement, second human activity recognition to detect a second activity state of the user of the device selected from a plurality of outdoor states based on the motion measurement, the second human activity recognition being performed without indoor state detection;
- and
- output the first activity state or the second activity state.

A device, comprising:
- a motion sensor configured to generate a motion measurement of the device;
- an electrostatic charge sensor configured to generate an electrostatic charge measurement of the device;
- and
- a processing unit configured to:
- determine a walking state of a user of the device based on the motion measurement, the walking state indicating the user is walking;
- determine a cycling state of the user of the device based on the motion measurement, the cycling state indicating the user is cycling;
- determine the device is indoors or outdoors based on the electrostatic charge measurement;
- in case the walking state is determined,
- switch the walking state determined based on the motion measurement to an indoor walking state that indicates the user is walking indoors in response to the device being determined to be indoors based on the electrostatic charge measurement, and output the indoor walking state, and
- switch the walking state to an outdoor walking state determined based on the motion measurement that indicates the user is walking outdoors in response to the device being determined to be outdoors, and output the outdoor walking state based on the electrostatic charge measurement;
- and
- in case the cycling state is determined,
- switch the cycling state determined based on the motion measurement to a stationary bicycle state that indicates the user is cycling on a stationary bicycle in response to the device being determined to be indoors based on the electrostatic charge measurement, and output the stationary bicycle state, and
- switch the cycling state determined based on the motion measurement to an outdoor cycling state that indicates the user is cycling outdoors in response to the device being determined to be outdoors based on the electrostatic charge measurement, and output the outdoor cycling state.
