An apparatus and method for determining a user activity include or define a plurality of baseline signatures, each baseline signature corresponding to a type of user activity and having data formed from a first data representing a varying static electric field and a second data representing motion. Data responsive to a varying static electric field is obtained from a first sensor, and data responsive to motion is obtained from a second sensor. The first data is combined with the second data, and the user activity is identified based on a comparison of the combined first and second data with the plurality of baseline signatures.
