Motion data settings and data granularity
SensorCore can be configured to collect data at different granularity levels. At the moment, two levels are supported: basic and detailed. A user can choose the level using the motion data settings 2.0 application.
The following sections will explain how the setting will affect different sensors. The setting will mainly affect the following:
- The amount of different activity types that SensorCore is able to classify
- The amount of data points and data accuracy provided by Place Monitor and TrackPoint Monitor
- Battery consumption
Basic data
This is the basic level of data that is available. Basic data is collected using the lowest battery consumption possible. Basic data is collected using only motion sensors like an accelerometer.
The following activity types are currently supported at the basic level:
- Unknown
- Idle
- Stationary
- Moving
- Walking
- Running
- MovingInVehicle
The following activity type is not currently supported at the basic level:
- Biking
In the basic level, Place Monitor and TrackPoint Monitor work passively and this behavior is identical to SensorCore 1.0.
Detailed data
The Detailed data level includes all data that SensorCore is able to classify. In this mode, SensorCore uses all possible data sources it has at its disposal to provide a data set that is as rich as possible. This also means that battery consumption in the detailed data level is higher than compared to the basic data level, but still 30%-50% less than on active apps that use a GPS.
The following activity types are currently supported at the detailed level:
- Unknown
- Idle
- Stationary
- Moving
- Walking
- Running
- MovingInVehicle
- Biking
In the detailed data level mode, Place Monitor and TrackPoint Monitor work actively. This means that the sensors utilize the user's activity states (like Idle, Walking, and MovingInVehicle) to dynamically control the usage of GPS.
As GPS is being used, the data collected by Place Monitor and TrackPoint Monitor will be greatly enhanced, providing more data point granularity than if the basic mode is selected.
