Designer: Taehyeong KimRightly called the DUO flexible mouse, the modular peripheral is designed to adapt to different usage styles with a foldable form factor. Just by folding or unfolding the rear of the device, a standard mouse shape or a vertical configuration is achieved. This is important because having a disposable AA or AAA battery inside can offset the balance while working in the vertical position. The standard mouse configuration, however, doesn’t have that liberty, as the fully folded position makes the mouse flat from the bottom, which is crucial for smooth operation on any kind of surface. Other than that, the overall concept design is highly practical and valid enough to be labelled a daily driver for power users like me.
