Title: LATENCY IN HEAD-MOUNTED DEVICES
In general, aviation information displays require some form of quality assurance due to public safety concerns. In recent years there has been an increase in aviation accidents which is due to poor visibility, inaccurate data correlation from Synthetic Vision Systems, and pilots’ situational unawareness. For instance, excessive time delay (latency) in aeronautic and other types of interactive real-time simulations can affect both perceived realism and aggregate human performance. In the case of head-mounted device simulators, temporal dynamic accuracy of details requirements are among the most important standards in aviation safety. In particular, such time delays, which occur due to data transport and computer processing from head-motion transduction and the graphical displays of the motion rendered in a head-mounted display, can make the surrounding virtual scene appear to swim and drift with respect to the user. This loss of visual spatial stability is thought to be a major contributor to motion or simulator sickness in interactive, immersive simulations. The goal of the study is to correlate various types of looking behavior with pilots' accuracy in maintaining a precisely specified route and safe flight, to support the formulation of new regulations and procedures. Also the incorporation of the systems latency measures in displays of head mounted devices with the use of a software interface to graphics hardware is also examined.
