Equipment and Software
For general availability to the largest audience, the computer implementation
was done for a low end PC using web standard JAVA Script. The lessons work on
all versions of Netscape and Internet Explorer 4.0 and later and do not require
any plug-in software, graphics hardware or special set-up by the users before
playing. The exception is that the user may choose to reset his screen to
display 600 by 800 pixels. Lessons also play on MAC systems, although at a
slightly increased rate. All programs were coded with time lines and customized
functions to incorporate specialized screen actions and responses. In-house
software was designed to create play arrangements to teach effectively while
avoiding a known pattern recognition by the students. Live images of people
using the items or doing the actions were processed as minimum sized animated
GIFs, with a standard sequence of three flowing images, to simulate live action
within the computer-generated images.
