A Redditor shared their prototype for a true single-handed controller combining the function of a mouse and keyboard in one device. u/Adventurous_Tie_9031, who also called themselves Joe, initially shared their design about a month ago, which they built after losing their right arm in an accident. They discovered that it’s difficult to continue playing games with just a single hand — whether using a mouse and keyboard combo or a traditional controller. Because of this, they decided to take matters into their own hand and created the ERCHAM MK1.
