Overview of Spatial Displays: Needs Assessment and Object Displays in Graphical Interfaces

This module presents a comprehensive overview of the needs assessment process, focusing on how it applies to spatial displays. It explores object displays, which integrate information from multiple dimensions to convey meaning through shapes and their interrelations. Topics include perception of graphical elements, judgments of proportion, and depth perception in 3D displays. An example such as the aircraft attitude display illustrates the importance of effective object displays in conveying critical information about orientation and spatial relationships.

    3. Aiding Preattentive Processing: Object Displays What is an object display? A display that integrates information from two or more underlying dimensions into a format that conveys meaning through shapes (objects) and inter-relations among shapes 3

    4. Aiding Preattentive Processing: Object Displays Examples of Object Displays Aircraft Attitude Display: represents aircraft orientation relative to the horizon angle indicates bank (roll) angle vertical position indicates pitch angle What makes this display integral?
