Designer Marco Schembri developed a minimal design concept for a Xiaomi calculator entitled the Xiaomi Mi08, introducing a new user experience. Instead of the traditional calculator with a number keypad, Marco Schembri took inspiration from vintage rotary telephones dial experience, adopting a wheel touch sensor, enabling the user to select the numbers without typing in buttons, resembling the physical interface of the iPod Classic. Through the Xiaomi Mi08, the designer developed a minimalistic, futuristic and retro look. Unlike other calculating devices, the project offers a new way to interact with the mathematical object, giving a new user experience to such a common object. The calculator can perform basic calculations and could be a great gift for any student, office worker or minimal design aficionado.
