System and method for providing improved detection of user inaction
First Claim
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.

Abstract
A mobile device, through the use of an NFC subsystem, may determine holster-proximity information, i.e., whether the mobile device is near to (including in) a holster or out of, and away from, the holster. The holster-proximity information may be used by the mobile device to enter into a user-inactive mode. Such entry into a user-inactive mode may involve disabling user interface components, such as input devices and output devices. In particular, the holster-proximity information may be used by the mobile device to disable the keyboard, that is, prevent presses on keys in the keyboard from being recorded. Such disabling may be considered of particular importance when the mobile device is going into and coming out of the 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.
