A small drawback is that the display does not accept a wide variety of standard formats. Do not expect to be able to directly watch a baseball or hockey game or custom video on the display, or to directly plug in a camera for using the display as a viewfinder. If you want to watch NTSC video, IEEE 1394 video, or other similar formats, you will likely want to run these signals through your WearComp first. Fortunately there is provided a converter box:

and the labeling on the bottom of the converter box shows the formats involved:

The device may be connected to a small WearComp such as the Xybernaut MA IV, by way of a suitable PCMCIA card supplying the needed video format, such as can be provided by this product:
