Magma
has been developed to provide a multisensory environment (sound &
images) for profoundly disabled people to explore.
It is
the third in the Ameba and Plazma
family of programs of Sensory software.
Of the three it is the "quietest" and most calming. Visually
it has much lower contrast and so may not be as suitable as the other
two for users who have very poor sight - but try it out with them
- you may be surprised. This package has been produced with a focus
towards children. However, you should find it to be useful with adults
too!
In our
experience, all three programs can be very useful with some children
who do not attend to the sensory world. They can work very well in
"sensory stimulation" rooms - both white and black rooms.
Magma
can be controlled by many different devices - all at the same time!
-Switches plugged into your PC will work (up to 10). These need to
be switches that either press mouse buttons or generate keystrokes
between 0 and 9.
-It also works really well using a mouse (including Head Mice) or
Touch Screen. It is especially good with a Trackerball. With a Touch
Screen you may want to turn of the ability for the Touch Screen to
click mouse buttons.
-A microphone plugged in will find Magma responding to both volumes,
fricative sounds (such as "sh" and "s") and also
pitch.
-A standard games joystick, gamepad or steering wheel will give many
options as users press the different buttons and move the cursor.
Sometimes
things happen when you press a switch, sometimes when you release,
and sometimes when you hold it down. Moving the cursor (even if you
can't see it) always produces a result. You can even press several
switches/ buttons/ keys together!
