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, wherein one of the plurality of aspects of the base level context is determined to be a mode of locomotion of a user carrying the electronic device, as a function of the motion activity vector, wherein one of the plurality aspects of the base level context is determined to be a nature of biologically generated sounds within audible distance of the user, as a function of the voice activity vector, wherein one of the plurality aspects of the base level context is determined to be a nature of physical space around the user, as a function of the spatial environment vector, wherein the determined mode of locomotion of the user comprises one of the user being stationary, walking, going up stairs, going down stairs, jogging, cycling, climbing, using a wheelchair, and riding in or on a vehicle, wherein the determined nature of the biologically generated sounds comprises one of a telephone conversation engaged in by the user, a multiple party conversation engaged in by the user, the user speaking, another party speaking, background conversation occurring around the user, and an animal making sounds, wherein the determined nature of the physical space around the user comprises an office environment, a home environment, a shopping mall environment, a street environment, a stadium environment, a restaurant environment, a bar environment, a beach environment, a nature environment, a temperature of the physical space, a barometric pressure of the physical space, and a humidity of the physical space, 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.
