When answers to these questions are completed, there will be a pretty clear picture of how monitor size effects the individual's productivity. A larger monitor may be the answer or speech output may be considered, or a combination of magnification with speech output may be the solution depending on how long the individual reads free from eye fatigue or headaches, reading speed, etc. The most important concept in using accommodation equipment is increased productivity and efficiency. That efficiency also includes how comfortable the individual can sit and work. The body must be positioned so that feet are flat on the floor and the back against the chair for support.
Legs are straight.
Leaning forward and holding the face close to the screen with no support causes back, neck and arm strain leading to ergonomic as well as the visual disability. The fatigue factor is increased with poor ergonomic alignment. Try several different font sizes in the demonstration magnification application, and note if any are read with ease from specific distances. Note reading speed with each font size selected. Note if the time the individual can read comfortably increases with a larger font size selected from the demonstration magnification application.
