1. A method of controlling an operation mode of a mobile computing device, said method comprising:
detecting proximity of a holster to said mobile computing device, wherein said detecting said proximity includes:
generating an electro-magnetic carrier field; and
sensing modulation of said electro-magnetic carrier field by a component of said holster, wherein said component of said holster uses load modulation to modulate said electro-magnetic carrier field; and
responsive to said detecting, disabling an input device to prevent input when said mobile computing device is both in and either going into or coming out of said holster.
2. The method of claim 1 wherein said input device is a keyboard.
3. The method of claim 1 wherein said generating said electro-magnetic carrier field is carried out in a frequency band centered at 13.56 MHz.
4. The method of claim 3 wherein said generating said electro-magnetic carrier field is carried out according to a known interface and protocol.
5. The method of claim 4 where said known interface and protocol is the Near Field Communications Interface and Protocol.
6. The method of claim 1 further comprising transmitting a command to said component of said holster.
7. The method of claim 6 further comprising receiving a response from said component of said holster.
8. A mobile computing device comprising:
an antenna adapted to generate an electro-magnetic carrier field;
an electronic circuit adapted to sense modulation of said electro-magnetic carrier field by a component of a holster and, upon sensing said modulation, transmit a report indicating that said modulation has been sensed; and
a processor adapted to:
receive said report; and
responsive to said receiving, disable an input device to prevent input when said mobile computing device is both in and either going into or coming out of said holster.
