HEAD MOUNTED DISPLAY SYMBOLOGY CONCEPTS AND IMPLEMENTATIONS, ASSOCIATED WITH A REFERENCE VECTOR
Head mounted displays (HMD) and corresponding display methods are provided, which obtain, repeatedly, from a monitoring system of a vehicle and, a reference vector relating to the vehicle; display on the HMD a reference symbol that indicates the reference vector; and determine movements of a HMD symbology according to a spatial relation between a received user's line of sight (LOS) and the reference vector. For example, the vehicle may be an aircraft and the reference vector a flight path vector (FPV) received from the aircraft's avionics. The proposed HMD enhances the displayed information content while avoiding excessive movements of the symbology. The HMD's functional parameters may be pre-set or adapted according to user preference and flight stage characteristics. The reference symbol anchors most of the symbology, while minimal critical information may be moved along with the user's LOS, providing a clearer and more stable view through the HMD.
Methods and systems are provided for using a user's line of sight (LOS) and/or gaze direction to enhance displayed data and control various displays and instruments. The user's LOS is tracked, corresponding element(s) in a scene at which the user gazes are identified, e.g., in a database, and respective displayed data are enhanced or otherwise manipulated with respect to the identified element(s). The database may be multilayered and may comprise data layers which are conformal to a scene representation. Users may also select, using their LOS, among multiple layers of information and among multiple displayed parts to enhance or attenuate respective layers or parts. Designated elements may be real-world elements, displayed elements or instruments in the operational surroundings of the user. Identification of elements at which LOSs of multiple users are aimed at may be used for exchange of information among the users.
Systems and methods are provided, for managing the attention of a user attending a display and for managing displayed information in control centers. Methods and systems may identify, from displayed data, a piece of information, locate a display position of the identified piece of information, and display the visual cue at a specified interval prior to displaying the piece of information, at a cue position on the display that has a specified spatial relation to the display position of the piece of information. Methods and systems may further quantify an attention pattern of a user, relate it to recorded reaction times of the user to the displayed data, and modify spatio-temporal parameters of the visual cues to decrease the user's reaction times according to specified requirements. Specific data may be enhanced according to user performance and various definitions.
