Control systems and methods for head-mounted information systems
First Claim
1. A head-mounted information system comprising:
- a frame configured to be mounted on a head of a user;
a display unit coupled to the frame, the display unit comprising a display for producing an image;
a sensor unit coupled to the frame, the sensor unit comprising one or more motion sensors; and
,a processor unit coupled to the frame, the processor unit connected to receive signals from the one or more motion sensors and configured to process the one or more motion signals to produce outputs representing parameters relating to user performance of a physical activity, the processor unit comprising a processor and a memory accessible by the processor,wherein the processor unit is configured to;
monitor the received signals and enter a gesture control mode upon occurrence of a gesture control enable signal, wherein in the gesture control mode the processor is configured to convert signals received from the motion sensors into menu navigation commands; and
in the gesture control mode, monitor received rotation signals to detect angular velocity about an axis to determine a first head angular velocity and compare the first head angular velocity to one or more threshold angular velocities to produce first motion control signals for menu navigation along a first direction.

Abstract
A head-mounted information system is provided, the head-mounted information system comprising a frame configured to be mounted on a head of a user, a display unit coupled to the frame, a sensor unit coupled to the frame comprising one or more motion sensors, and, a processor unit coupled to the frame and connected to receive signals from the motion sensors. The processor unit comprises a processor and a memory accessible by the processor. The processor unit is configured to monitor the received signals and enter a gesture control mode upon detection of a gesture control enable signal. In the gesture control mode the processor is configured to convert signals received from the motion sensors into menu navigation commands.
