Reading scrambled words
This program tests (not very scientific) the hypothesis that we are capable of understanding a text when each word have the first X letters and last Y letters inplace and the rest is either sorted or scrambled randomly. (Well, almost random, since I check that the generated substring is not equal to the original substring. This is of course only be possible for words with length >= X + Y + 2 and where the characters in the substring is not the same.)
The first Swedish examples I saw are here (with X=2, Y=2, from September 1 2003) and here (X=1,Y=1, from September 15 2003) respectively. For an english text see this blog thread.
The sorting option was inspired by Niklas Johansson's comment (in Swedish).
He is inclined to think that the word seems to be less understandable when the no-fixed characters are sorted. I tend to agree with him.
Type in a text in the text area, change the number of characters to keep at the start and the end of the words. Also choose if the no-fixed words should be sorted. Then click on "OK" to proceed. The scrambled text will be shown below. How readable is it?
Test the program with an english text here.
Parameters: X = 2, Y = 2
En veseptnlkaig unesdrköinng gjord vid ett unvieirstet i Enlagnd har visat att utfiall de två fösrta och de två sista boktsevräna i alla orden i en text är rikitgt plaaercde, splear det liten roll i viklen orginfdlnsöjd de övirga boeävksrtna i orden kommer. Tetxen är fullt läbsar t.o.m. om de andra boästrekvna kommer hueumlllrlober! Detta efrsteom vi inte läser varje eniskld boktsav, utan ser bidlen av ordet som hehlet.
Maybe there are some comments of my (Swedish) blog post announcing the program.
