Caleb Kraft has already created a number of projects involving custom gaming controllers for people with physical disabilities. His latest project is a custom foot controller, which he built for his friend Jesse, who is not able to use his left hand but his feet instead.
Caleb describes the single steps of this process in a series of videos. He created foot controls replacing the left analog stick and d-pad using 3D modelling and 3D printing, baring in mind that the designs could theoretically be used in many other ways in the future, not just feet.
