Is there any equipment or tool that can help improve eye-hand coordination in seniors?

When we write, we use hand-eye coordination. Our eyes send visual data to the brain to show it where the hand is when we start making lines, and if our handwriting is readable, the brain produces instructions for how the hand should function to make fine lines and shapes, which are letters.
Visual feedback another usage is correcting unreadable shapes (letters) created by previous motor instruction. It’s a chain of fast and detailed actions that needs a particular amount of skill and training. When we type on a keyboard, a similar set of activities occurs. Although the type of movements is not alike, we still use visual information to tell the brain how to guide the hand or if an error should be cut out.

While driving, we use hand-eye coordination. We need visual data to make out hands move on the steering wheel, drive the car in the middle of the lane and keep away from accidents. Nearly every sport needs to use hand-eye coordination to synchronize the movement of our body with what we see with our eyes. Based on what sport we do/play, each hand-eye coordination (tennis, football, and handball) and foot-eye coordination (track, soccer, etc.) could be the more dominant one. A better term for this kind of coordination could be motor coordination because no matter what the sport is, we always know that our eyes will be syncing with some part of our body.
Another example of hand-coordinating action is putting a key in a lock. Likewise, when you put a credit card in a chip reader or when children play with those toys with shapes that fit into a specific hole.
