Marker Based Activity Transition Models

A client device for gathering mobility information of a user, the device comprising

• a sensor data obtaining means configured for collecting sensor data representative for transportation-characteristic information of a user,
• a marker information obtaining means configured for collecting marker information, the marker information being related to an environmental characteristic of the user or an activity of the user not determined based on a transportation characteristic,
• a processor programmed for combining the transportation-characteristic information of the user and the marker information so as to be able to determine based thereon mobility information of the user, and
• an output means adapted for outputting the combined transportation-characteristic information and the marker information.

A method for gathering mobility information of a user, the method comprising the steps of

• collecting sensor data representative for transportation-characteristic information of a user,
• collecting marker information, the marker information being related to an environmental characteristic of the user or an activity of the user not determined based on a transportation characteristic,
• combining the transportation-characteristic information of the user and the marker information so as to be able to determine based thereon mobility information of the user, and
• outputting the combined transportation-characteristic information and the marker information
• and/or the steps of
• receiving a combination of sensor data representative for transportation-characteristic information of a user and marker information being related to an environmental characteristic of the user or an activity of the user not determined based on a transportation characteristic, and
• determining based on said combination mobility information of the user.
