[From Rick Marken (961129.1800)]

I've been trying to learn Java (no mean feat considering my age and and my  
IQ) because I thought it might provide some people easier access to the  
control demos that we talk about on CSGNet. I have finally completed a  
couple of Applets and they are now available at my web site. To see them,  
first go to my "Mind readings" home page at:

[http://www.leonardo.net/Marken/](http://www.leonardo.net/Marken/)

After ordering several copies of the book;-) click on my name which will  
give you access to the two "On-line Control Demos". If you have a Java  
enabled browser (I think Netscape 3.0 is Java enabled on essentially all  
platforms) you will be able to see the demos. One is the basic, one-  
dimensional compensatory tracking task; the other is a version of my  
"Mind reading" demo (which continuously tests to determine which of three  
squares is being moved intentionally).

I would be interested in hearing how these demos "look and feel" on  
different platforms. I'm running them on a Power Mac (120 MHz); I've seen  
early "application" versions of these programs on a Sun Sparc and on a  
Pentium PC but I haven't seen them run in different browsers. If you are  
able to run them and would like to make comments or suggestions, please  
send them to me direct at this address ([marken@leonardo.net](mailto:marken@leonardo.net)). Let  
me know if the animation and (especially) the effect of the handle on the  
animated images is reasonably smooth. Also, let me know if the format of  
the browser display is OK or whether it could be improved to better fit  
your browser.

Let me quickly point out that I am NOT yet a Java programmer. These  
programs a \_not\_ elegant; they are pretty ugly from an "object oriented"  
point of view; and I don't use many of the nice features of object  
oriented programming (that's why I'm not making the source available; it's  
pretty embarassing;-)).

But at least the programs \_work\_. I still have a lot to learn and I'm not  
sure this old dog can learn these new tricks -- but I'm trying. The Java  
approach to making the PCT Demos accessible seems rather promising.

Best

Rick
