Helmet-Mounted Display (HMD) Interface Design for Head-Up Display (HUD) Replacement Exploratory Development - NTL, Inc.
Abstract
Increasingly, helmet-mounted displays (HMDs) are replacing "head-down" and Read-Up Displays (HUD) in advanced cockpit interface designs. HMDs offer potential advantages by providing pilots with more direct access to critical visual information, while offering greater flexibility of head movements, less weight, and less consumption of cockpit space. Much of the symbology, functionality, and mechanization found in current HMDs can be traced directly to HUDs. But, because HMDs are decoupled from the longitudinal axis of the aircraft, different kinds of information can be presented on HMDs. Thus, questions arise concerning the best manner in which to present the additional information, and its interaction with traditional HUD information. The purposes of this effort were to define the human performance requirements for both HUD and HMD interfaces as utilized in military missions, and to produce a preliminary HMD design for a no-HUD aircraft. To establish the functional specifications for the interface design, a user-centered design approach employing cognitive work analysis was employed.
