1. A method for controlling a head mounted display (HMD) system that includes a microdisplay, a user input device, a first processor, and two or more other peripheral circuits comprising:
- entering a first state by enabling only the first processor and user input device;
detecting a user input;
interpreting, with the first processor, the user input as a spoken command or gesture command; and
entering a second state by the first processor issuing a command enabling a selected ones of the two or more other peripherals and the first processor issuing a command disabling other peripherals based on the spoken command or gesture command;
wherein the two or more peripherals include a second processor, the second processor configured to consume more power relative to the first processor.
