Data collection applicaton for paper "Discovering User-context in Indoor Space".

We discover user-context in indoor space by combining activity and location context for user. This application is used for data collection purpose.

The following sensor's data collected from android phone:

• Gyroscope
• Accelerometer

The coordinates of each user were collected by an indoor positioning application - BuildNGo.

Application can be reused in the following way:

1. Define ground truth data format in strings.xml file:

• actions_array: Actions, which will be performed by participants (write, type, listen, etc.)
• room_array: Locations, where participants located
• user_array: Participants, define unique id for each one

2. Provide BuildNGo token and building ID in MainActivity.java:

private static String TOKEN = "...";
private static String BUILDING_ID = "...";

Next step after collecting data is preprocessing. Follow this project description.
