These Google Glass control was migrated from the prototype 3D printed frame to a large heavy lift quadcopter gimbal. Below is a demonstration of real-time wireless control of the pitch and roll axes of a heavy-payload carrying gimbal, controlled hands-free by Google Glass. This control is a applied to a project I worked on at Simera Technology Group, see: Anax Heavy Lift Quadcopter.
Unfortunately the yaw motor for the large gimbal is faulty, but a full three-axis demonstration video will be posted as soon as the gimbal motor is replaced.
To apply this project to your own gimbal system, you can see my instructable:
