Head Mounted Display

The requirements for a head mounted display to be used with this remote inspection system are listed below.

Stereo display capability - To generate the 3D effect of depth perception, two images are needed, one from the left eye, and one from the right eye. A helmet with two separate video displays is needed.
Light weight/comfortable - If the helmet is too heavy, or uncomfortable, the operator will not be able to wear it for any length of time, and it will not be used.
Allow viewing of monitor - The helmet should not be of the completely enclosing type; the operator should be able to see both the helmet's displays, and the operator workstation monitor without removing the helmet.
Good color display - Color is essential in determining the condition of drum surfaces.

The CyberEye CE100-S color stereo head mounted display by General Reality Company meets all of these requirements.

The CyberEye was the only helmet found which could be worn while still viewing the workstation monitor, as shown in the figure below.
