| The typical advanced head mounted display has sensors which can change the opacity of the lenses from entirely opaque to nearly transparent. Data projection technology allows information from databases and overlay maps to project an everted data set onto the display field. In its simplest form the HMD acts as a simple projector suited for projecting data fields from an eversion unit or sixth sense device onto surfaces within the field of vision. |
||
HMD SYSTEMS |
||
| More powerful systems are actually built into the optics allowing the hmd to act as a virtual immersion device at full opacity by acting as a projector directly onto a screen in the lens. | ||
Viewing Modes |
Perception
|
|
| In semi-transparent mode the optics act as a navigational and projection overlay which can either be operated in full projection mode or view mode. View mode allows the hmd to be seen only by the user, while project mode actually sends downloaded or stored data in visual form onto surfaces using basic projector technology. Data presented in this way can be displayed on any suitable surface to allow object tagging, object identification mapping or to create an advanced information display. |
Head mounted displays can also serve other purposes by combining features with other electronic sensor devices to expand the field of awareness. | |
Real Time Connectivity |
||
|
An HMD with real time internet connectivity can actually use image mapping, verbal commands, optical commands or kinetic command signals to activate and call up data maps to create a fluid field of information which is everted onto physical surfaces. The HMD can be set in communication mode to transmit information wirelessly on an encrypted or open signal to a device with matching protocols. The wearer of the receiving device(s) can then access information directly with a matching data overlay. This can be useful when, for instance, communicating with a team member or a personal contact over a significant distance, and ensuring that all parties are literally on the same page. The value of the HMD is in its utility for training, communication, tactical coordination as well as in its ability to handle multiple data screens through a paging ring or similar accessory. |

Models Availability and Price |
||
| HMD | ||
| The price of an HMD varies greatly with the model and the software and hardware capabilities of the unit. Fully integrated HMD displays are not on the general market, but they are expected within a few years. Basic HMD setups are available, although truly advanced full featured models are a constant work in progress | ||
