Method for detecting context of a mobile device and a mobile device with a context detection module

A mobile device, comprising:

• a plurality of sensors and a plurality of sensor groups, wherein each of the sensor groups is assigned at least one of the sensors, and wherein the sensor groups are arranged according to a hierarchy;
• a plurality of classifiers, wherein each classifier is assigned to a sensor group, and wherein each classifier is configured to evaluate one or more contexts of the mobile device based on signals from one or more sensors assigned to the same sensor group as the classifier;
• and
• a context detection module configured to:
• evaluate a first context of the mobile device by activating classification using at least two of the classifiers in sequence according to the hierarchy;
• and
• adapt a configuration of a classifier assigned to a lower level sensor group in the hierarchy based, at least in part, on a result of a classification by a classifier assigned to a higher level sensor group in the hierarchy.

A method for detecting a context of a mobile device equipped with a plurality of sensors, comprising:

• assigning the plurality of sensors to a plurality of sensor groups, wherein each sensor group is assigned at least one sensor;
• arranging the sensor groups according to a hierarchy;
• activating a classification by a classifier assigned to a second sensor group after a result of a classification by a classifier assigned to a first sensor group, wherein the second sensor group is at a higher level in the hierarchy than the first sensor group;
• and
• adapting a configuration of the classifier assigned to the first sensor group based, at least in part, on a result of the classification by the classifier assigned to the second sensor group.

A non-transitory computer-readable medium having instructions stored thereon for causing a system to detect a context of a mobile device equipped with a plurality of sensors by:

• assigning the plurality of sensors to a plurality of sensor groups, wherein each sensor group is assigned at least one sensor;
• arranging the sensor groups according to a hierarchy;
• activating a classification by a classifier assigned to a second sensor group after a result of a classification by a classifier assigned to a first sensor group, wherein the second sensor group is at a higher level in the hierarchy than the first sensor group;
• and
• adapting a configuration of the classifier assigned to the first sensor group based, at least in part, on a result of the classification by the classifier assigned to the second sensor group.
