Yesterday’s work with
‘John’ (not his name) was very interesting.
With his agreement I shall simply report the data we obtained.
This data was collected using a binocular eyetracker.
Silent reading of basic
text on a default computer screen taken gave a reading speed of 49.6 words per
minute.
Font size 12, background 255/255/255 Dell Inspiron laptop. Factory setting
background full luminance.
Characters per fixation……… 1.4
Words per fixation…………….0.24
Silent reading on his
optimised computer screen gave a reading speed of 183 words per minute
Font size 12, background settings… Red 43 Green 161
Blue 162
( I could not get the font size correct when I copied this onto the blog. Sorry.)
Characters per fixation…….6.0
Words per fixation…………..1.0
After reading on his
optimised background for 20 seconds these performance figures had changed to
the following.
Reading speed had increased to 216 words per minute.
Characters per fixation…..7.48
Words per fixation…………1.3
