A few days ago I received an email asking whether we could produce a Dream-Gamer PlayStation PS2 controller with a large joystick.

We make three different Dream-Gamer control systems: cap controller which uses head movement, switch access designed with switch users in mind and a low profile mini-joystick. Adding the Big-Ball joystick would be something new and potentially beneficial to gamers preferring to grab hold of a larger device.

Take a look at the video if you would like to see Callum using the mini-joystick and read the comments from mums Jane and Karen.

We decided to make the Big-Ball joystick around the size of a Traxsys joystick - well known in the assistive technology community.

Big-Ball connects to the left hand side of the Dream-Gamer PS2 controller and works just like a regular joystick to control direction in the game.

We can also adjust its sensitivity to enable different users to tune it to their own abilities.

I'm hoping I can take it along to Blackfriars School and ask the students there to give it a thorough work-out.
