Players who are blind or visually impaired can play boccia using a VI grid to assist them.

The grid works by plotting what is happening on court, for example the white jack ball will be plotted and then the corresponding coloured pegs thereafter.  

All the court markings are on the grid which has raised lines referencing each metre square.  These allow the plotter and the player to easily reference the dimensions from court to grid.

In a competition setting: All athletes in the visually impaired category (BC7) wear an eye shade and have an assistant/plotter who stands behind the box and plots the balls as they are played.  The plotter is not permitted to talk to the player in order to not provide advice or tactics.  The player can ask for the grid at any time.
