1. An electronic device, comprising: a sensing unit comprising at least one sensor and being configured to acquire sensing data; a computing device configured to: extract sensor specific features from the sensing data; generate a motion activity vector, a voice activity vector, and a spatial environment vector as a function of the sensor specific features; process the motion activity vector, voice activity vector, and spatial environment vector so as to determine a base level context of the electronic device relative to its surroundings, the base level context having a plurality of aspects each based on the motion activity vector, voice activity vector, and spatial environment vector, and determine meta level context of the electronic device relative to its surroundings as a function of the base level context, wherein the meta level context comprises at least one inference made from at least two aspects of the plurality of aspects of the base level context.
