Description: This Standard determines required display image size and relative viewing positions for two defined viewing needs: Basic Decision Making and Analytical Decision Making.
The Standard can be used to design a new space or to assess/modify an existing space. It applies to both permanently installed systems and temporary systems. When planning a display, audiovisual designers often encounter limitations with dimensions and layout in relation to optimal displayed image size. This Standard provides formulas to design and display suitable content. The Standard provides a calculation/assessment tool for determining proper display image size based upon viewer needs as defined under two main categories.
Who should use this standard? Anyone who needs to: Plan and design new displayed image systems Determine image size relative to the space and viewing requirements Determine Closest and Farthest Viewer Positions Determine horizontal angles of view Provide metrics for content design Use of this Standard is intended for display images in fixed and temporary installations.
