PIE2LANG.TBK - by Paolo Tosolini  April '93
---------------------------------------------

This is an Asymetrix Toolbook v. 1.5 file.

PIE2LANG.TBK is a prototype of gesture user interface
for applications that use natural language inputs.

It implements the idea of the Pie Menu as alternative
to the traditional linear menu.

The book contains the necessary instructions to use it.
No fee or money is absolutely required.

Suggestions and new ideas are welcome. Let's try togheter to
improve Toolbook's application interfaces.

Please, email your opinion, and you will be kept updated directly
of new coming versions.
