what if one did not have to move their eyes across a piece of text to grasp it?

Thanks Sam, for this interesting piece of news. But the news is not that happy as of now-when spritz was put to test by BBC Click's Spencer Kelly using spritz against normal reading with Dr. Katherine Brown of New College of Humanities, Spencer couldn't pass the simple test conducted after one minute reading the text. This shows the failure of the technology as of now. But it could open new doors in future. In eye-tracking experiments, we conduct self paced reading test using moving windows paradigm which is quite close to spritz. We haven't compared the difference though.

Happy Holi!

Well,

Scores: Spritz 0.5 and normal reading 2!!!

I guess we eye-tracking people will not go out of business that soon!!!

I am sure Spritz will be able to do a better job if the person does a lot of trial sessions on it, but cannot be as accurate as normal reading. Spritz goes against a lot of fundamentals that we already know in reading; one of them being that we do not look at each and every word while reading and that we do skip over a lot of them!

Also, reading is an online process, as and when you start reading a sentence you start to process the sentence (you start constructing a phrase structure). Now in a Spritz environment it will be seriously handicapped. Another instance is of backtracking, almost 15% of the times, we backtrack while reading, thereby meaning that backtracking is significant in reading (especially syntactically or semantically complex) sentences! Spritz overlooks it completely!

Spritz developers should go through the gigantic literature on sentence processing first and may be employ some young scholars who have been working in the area too!!! :p

Best,

Kiran

the important point is to see the consequences of preventing readers' eye movements along a piece of text. spritz doesnt allow the reader to backtrack and the rate of showing a word is much higher than normal reading. I tried it on their website and was able to read comfortably at 350 words per min. at 500 words per min I felt I was unable to grasp few sentences. but I feel some practice could get me up to 600 wpm.
