1. A device, comprising:
- a receiving surface for at least one human hand to grip thereon;
a plurality of capacitive sensor elements disposed within at least one location on the receiving surface, wherein the capacitive sensor elements generate capacitance measurements;
a sense circuit coupled to the capacitive sensor elements configured to compare the capacitance measurements with threshold capacitance values, wherein the sense circuit is further configured to generate a signal when the capacitance measurements indicate close proximity of at least a portion of the at least one human hand to the capacitive sensor elements; and
an indicator configured to receive the signal from the sense circuit and generate an indicator notification when the position of the at least one human hand relative to the receiving surface corresponds with the at least one location on the receiving surface.
