Aimed at preventing RSI, this program warns you to take breaks after a
configurable interval, based on clock time, or after a set number of
keystrokes - whichever is earlier. It gives you 3 exercises to do each
time, randomly selected from a set of 70. Exercises are apparently tuned

processing. Exercises are illustrated and include quite a lot of text on
how to do the exercise and on what exactly the exercise does.
CHB includes hypertext information on RSI that you can use to learn more
about RSI and how to prevent it. Other information on non-RSI topics can

and jargon is included.

to take a break; it does not therefore appear useful when used with
The keystroke-counting approach looks good: it seems better to

clock time or even typing time. The marketing stuff is very good and
includes some summaries of research papers, as well as lots of
arguments you can use to get your company to pay up for RSI
