Ameba 
            has been developed to provide a multisensory environment (sound & 
            images) for profoundly disabled people to explore.
            
          This 
            package has been produced with a focus towards children. However, 
            you should find it to be useful with adults too! 
            
          Ameba 
            can be controlled by many different devices - all at the same time!
            -Switches plugged into your PC will work (up to 8). These need to 
            be switches that either press mouse buttons or generate keystrokes 
            between 0 and 8.
            -It also works really well using a mouse (including Head Mice), trackerball 
            or Touch Screen. 
            -A microphone plugged in will find ameba responding to both volume 
            and fricative sounds (such as "sh" and "s"). It 
            also responds a little to pitch.
            -A standard games joystick, game pad 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!
