Foot Scroll

Hands-free scrolling, designed for comfort.

Developed a foot-controlled interface with Arduino and belt-drive mechanics, enabling pain-free navigation.

Scope Mechanical Design, Embedded Programming • Client Chronic finger-fatigue case • Duration 3 months • Year 2022

/ Challenge

A client with chronic finger fatigue needed an affordable, ergonomic alternative to a standard mouse.

/ Solution

Foot-operated scroll pedal engineered with Arduino control and optimized mechanics, enabling precise navigation with adjustable sensitivity.

/ Results

Now used daily without pain; the FootScroll won 1st place in Design Day’s Accessibility category.
