This workshop should be of considerable interest to CSGnet members

DACCHI means  
I know Rick has worked on PCT and interface issues, and I imagine  
that several others also have done. The first sentences of the  
workshop description (extended abstract) are: -------  
The idea of continuous dynamic interaction was first explored by  
Powers in the 1960s [2], although the field might be dated back to  
James Clerk Maxwell’s work with steam engine governors in the 19th  
century. The Powers’ work showed that many kinds of behaviour can be  
usefully described as continuous control problems. This viewpoint  
provides an empirically-based method for the explanation and  
quantitative analysis of a user’s intentions. This workshop will  
provide a focal point to the engineering of “continuous” and  
“dynamic” interaction as means of interfacing with computing  
systems.

RM: Yes, that does look interesting indeed. I might do it if they let me do it by Skype or something.If you read the rest of the abstract it's clear that these people don't really understand what Powers' was about. (Actually, you can tell from just this part of the abstract where it says "Powers’ work showed that many kinds of behaviour can be

```

usefully described as continuous control problems". In fact Powers work showed that all behavior is continuous control – the “continuous” modifier never having been used by Powers since it’s unnecessary). But I suppose it’s better than nothing.

Dr. Marken,

I would just like to say I appreciate the “gain” and sensitivity of your system.

RM: Under the assumption that you are not being sarcastic, thank you very much, Andrew. I appreciate it.
