Tap 
            Here has been developed for switch users. It provides a range of single 
            switch activities from just pressing the switch to get a sound and 
            animation reward, to activities that involve timing and/or scanning 
            skills.
          The 
            switch (es) can be connected to the serial port or can be activated 
            by a mouse click (maybe Touch Screen emulating a mouse?) or by keyboard 
            presses.
          This 
            package has been produced with a focus on children with profound and 
            multiple learning difficulties. However, you should find them to be 
            useful with adults too.
