Claim 0:
1. A controlling device, comprising:
a transmitter;
a plurality of input keys each comprising a switch for generating an activation signal when pressed by a user and a touch sensor for generating a touch data when touched by the user;
a processing device coupled to the plurality of input keys; and
a memory having stored thereon processor executable instructions, the instructions, when executed by the processing device, causing the controlling device to perform steps, comprising:
receiving a plurality of touch data from each one of a corresponding plurality of the plurality of input keys;
determining a one of the plurality of touch data that indicates a highest increase of a parasitic capacitance to ground value; and
transmitting to a smart device via use of the transmitter a first key id associated with a one of the corresponding plurality of the plurality of input keys from which is received the one of the plurality of touch data that indicates the highest increase of the parasitic capacitance to ground value.
