The program includes a number of activities:
- revealing all or part of a picture
- painting pictures by area, groups, or using a grid.
Options include colours on/off, stepping through colours, by choosing colours from a palette.
Activities can be set in one of the many styles available, including loading your own pictures to use. Any configuration can then be saved to disc.
Works with touch screen or other access/input system that controls the mouse.
Note: Knockout can be set up to use the sound effects files produced by the program Listen Hear, or can just use standard .wav files.
Knockout lets the user change areas of an image - such as the colour of windows and the door in a house, or colours in patterns. Some options enable users to receive a sound reward on completion of a task. Reveal allows you to uncover areas of an image in steps, including a 'snaking' option that only permits a limited area of the image to be on view at any one time. Both programs allow you to include your own pictures.
