Abstract:
This report describes a concentrated effort to identify and quantify the parameters involved in the design of matrix displays for legibility and to assess the design trade-offs against the criterion of symbol legibility. A literature survey was conducted to determine what information previously existed and its applicability to matrix displays. The literature survey is included as an appendix to this report.
