Suggestions for tweaking output.script for optimal settings
Make gaze target a reasonable size
The display computer's monitor may need to be adjusted for presentation accuracy.
Original screen resolution: 1920 × 1080 (maximum size)
Experimental screen resolution: 1280 × 800
To make the text legible, but not so big that you require multiple lines for reasonable length sentences, the following settings can be used. At these settings, there are 99 characters across the screen.
Trials:
Reading: 16 25 50 200
Question: 16 50 70 350
Message: 16 25 50 50
It seems that the text size can only be certain numbers, though.
(e.g., 12, 14, 16)
The first number in each of the settings is the text size.
The second number might the distance to the left edge of the screen in pixels.
The third number might be the line height of each line of text.
The fourth number might be the distance to the top edge of the screen in pixels.
