What it does
KIUS addresses health problems caused by prolonged computer use—such as carpal tunnel syndrome and poor posture—by integrating keyboard and mouse functions into one device, minimizing repetitive motion and reducing physical fatigue.
Your inspiration
KIUS was inspired by the rising number of people silently suffering from wrist, shoulder, and neck pain caused by daily computer use. As students and creators ourselves, we noticed this discomfort was not rare—it was routine. From office workers to designers, many struggle with chronic strain from standard keyboards and mice. While ergonomic products exist, they are often unfamiliar or hard to adapt to. We believed there had to be a better way—one that respected both the body and user habits. KIUS was born from this idea: to create an intuitive, ergonomic device that prevents pain without disrupting the user’s workflow.
How it works
KIUS combines a split ergonomic keyboard with built-in mouse functions to minimize movement and maintain neutral wrist posture. The keyboard is divided into left and right sections, angled to match natural arm positions and reduce wrist twisting. A touch-sensitive zone and cursor keys between the key clusters allow seamless pointer control without reaching for a separate mouse. Clicks and scrolls are handled by thumbs or index fingers within the typing area, reducing shoulder movement and neck tension. The surface is slightly tilted to relieve wrist compression. KIUS is plug-and-play, compatible with standard systems, and requires no steep learning curve. Unlike devices that require learning new gestures, KIUS supports long hours of work with familiar, strain-free interaction.
Design process
The development of KIUS began with firsthand research into the discomfort experienced by long-term computer users. We surveyed students, office workers, and designers to understand their pain points. Initial sketches explored split keyboard layouts and integrated cursor zones. After refining the concept through user feedback, we created a 3D CAD model using Fusion 360 to simulate ergonomics and hand positioning. The biggest challenge was maintaining intuitive usability while merging two devices. We performed mock hand placement tests to determine optimal key spacing and thumb controls. Using FDM 3D printing, we built the first physical prototype. Keycaps were designed to be slightly concave to guide natural finger movement, and the device’s tilt angle was tested to reduce wrist tension. Throughout the process, we consulted occupational therapy resources to validate ergonomic choices. After several iterations, we produced a refined working model that allowed users to type and control the cursor without shifting arm position. The prototype was tested by real users, whose feedback confirmed its comfort and accessibility. This iterative, user-centered approach helped shape KIUS into a functional, ergonomic, and production-ready solution.
How it is different
Unlike existing ergonomic devices that separate keyboard and mouse functions or rely on unfamiliar interfaces like trackballs, KIUS offers a seamless, intuitive solution. It combines both functions into one natural form without sacrificing usability. While other hybrids often feel like two tools merged together, KIUS is designed from the ground up as a single, unified device. Its split layout supports neutral wrist posture, with mouse controls placed naturally within finger range—allowing movement, clicking, and scrolling without lifting the hands. The familiar form reduces the learning curve and increases accessibility. Rather than asking users to learn a new system, KIUS enhances the one they already know. Every design decision ensures the keyboard and mouse aren’t just combined—but truly integrated. This harmony is what sets KIUS apart: it feels natural, works intuitively, and supports health without sacrificing productivity.
Future plans
Our goal is to bring KIUS from prototype to market-ready product by refining its design, optimizing materials, and developing customizable software. We’ll collaborate with ergonomic manufacturers and run broad user testing. Long-term, KIUS will integrate with wellness apps to support posture tracking and aims to set a global standard for healthy, sustainable work.
