After losing his right arm in a motorcycle accident, a gamer designed and built a unique controller that can be used with one hand. He’s now starting a Kickstarter campaign to raise money and potentially manufacture the device for others.
The inventor of the device created Ercham because they found traditional keyboards and mice difficult to use. They designed it as a single unit that combines both functions and can be operated with just one hand.
Custom controller evolved from modified keypad and mouse setup
Joe has since explained how he built the device, sharing details on its website and on Reddit to get more people interested. He started by using a Razer Tartarus as a foundation and experimenting from there.
To make it easier to use with one hand, they changed the controls, connected a mouse to the side, customized the button functions, and added a strap for better grip.
The first version let players move, aim, click, shoot, and use abilities again, which showed the basic idea was sound, even though it wasn’t polished yet.
Building on their initial work, they created a completely new and improved device. While maintaining a familiar design, they consolidated everything into one unit. This updated controller featured a built-in mouse sensor, customizable button controls, a hand strap for comfort, and extra inputs – all designed to minimize hand strain and allow for extended use.
The device’s creator explained they were building it with unique software so it would work immediately when plugged in, without needing extra programs that might interfere with anti-cheat measures in games.
The controller is now being manufactured and will be available more broadly soon. Updates on its development will continue to be posted on the Ercham project page.
They expressed a desire to create this product for children with physical disabilities and gamers who need more accessible choices.
If you’d like to help fund this project, you can donate through a GoFundMe campaign called “Help make one-handed gaming real.”
