How can a player be assisted when they cannot see the jack or a toucher while standing on the mat?

When a player cannot see the jack or a toucher while standing on the mat, the use of a white indicator marked no more than 50 mm wide and 100 mm high serves as an effective tool for assistance. This indicator helps in clearly marking the spot of the jack or toucher, making it easier for the player to understand the position of the target.

The specific measurements of the indicator ensure it is visible without obstructing the play or causing distractions. This guideline is designed to maintain fairness and clarity during the game, allowing players who may have visual impairments or are simply unable to locate the object of play to continue competing effectively.

Using an indicator that adheres to these specifications ensures consistency in gameplay, as all players will know what to look for when they cannot see the jack or toucher clearly, promoting better understanding and smoother play.
