Abstract: An electronic device includes a printed circuit board (PCB) having at least one conductive trace thereon. A system on chip (SoC) is mounted on the PCB and electrically coupled to the conductive trace. A sensor chip is mounted on the PCB in a spaced apart relation with the SoC and electrically coupled to the conductive trace such that the sensor chip and SoC are electrically coupled. The sensor chip includes an accelerometer and/or a gyroscope, and a control circuit. The control circuit is configured to receive configuration data as input, acquire data from the accelerometer and/or the gyroscope. The control circuit is also configured to process the data so as to generate a context of the electronic device relative to its surroundings, the processing being performed in using a processing technique operating in accordance with the configuration data, and output the context.

Abstract: An electronic device described herein includes a sensing unit having at least one sensor to acquire sensing data. An associated computing device extracts sensor specific features from the sensing data, and generates a motion activity vector, a voice activity vector, and a spatial environment vector as a function of the sensor specific features. The motion activity vector, voice activity vector, and spatial environment vector are processed to determine a base level context of the electronic device relative to its surroundings, with the base level context having aspects each based on the motion activity vector, voice activity vector, and spatial environment vector. Meta level context of the electronic device relative to its surroundings is determined as a function of the base level context, with the meta level context being at least one inference made from at least two aspects of the plurality of aspects of the base level context.
