After Losing His Arm in a Crash, He Built the Controller No One Made - Yanko Design
"The core idea is to put the keyboard and the mouse into the same device so that one hand handles everything at once. The Ercham MK1 sits flat on a surface, and an optical sensor on its underside lets the entire unit glide like a conventional mouse."
"The key section features more than 30 programmable inputs arranged in a compact grid within natural finger reach. A strap system runs across the top of the device, keeping the hand firmly in place during longer sessions without requiring a tight grip."
"One of the more considered design decisions is that the Ercham MK1 works for either hand. Most gaming keypads aren't built for both; they default almost universally to left-hand use, leaving right-handed amputees and players with right-side impairments without a natural fit."
The Ercham MK1 is designed for gamers who can only use one hand, integrating keyboard and mouse functions into a single device. It features over 30 programmable inputs arranged for easy access and an optical sensor for smooth movement. A strap system secures the hand, accommodating players with limited strength. Unlike traditional gaming keypads, the Ercham MK1 is ambidextrous, catering to both left and right-handed users, thus providing a more inclusive solution for gamers with disabilities.
