The Head-Up Display in the Automobile Environment
Abstract
The head-up display (HUD) enables the user to view critical instrumentation without redirecting his or her gaze from the outside environment. With the HUD, instrument-panel symbols appear as virtual images at optical infinity, superimposed upon the external scene. The concept has been so successful within the aerospace industry that automobile manufacturers are beginning to implement HUD technologies in automobiles. The purpose of this thesis was to evaluate HUD effectiveness in a simulated automobile environment using realistic driving tasks. Twenty male and female subjects with a wide age distribution (19-51) participated. A videotape, taken from the driver's perspective, of a car travelling along a route served as the 'scene' that was viewed by each subject. While watching the scene, subjects were required to perform driving tasks related to navigation, speed monitoring, and salient cue detection. Results showed that use of the HUD enabled subjects to respond more quickly to the salient cues, and that more cues were detected when using the HUD. In addition, more speed violations were detected by those subjects using the HUD. Theses
