This video demonstrates how coded access to an alphabet chart works. The colours are used to indicate the column or y-axis of the target letter, and the numbers are used to indicate the row or x-axis. Note that the layout can be made more complex by adding in whole words / phrases etc. The chart of codes can be accessed by direct touch, listener mediated scanning or eye pointing.
