“KnobSlider is a shape-changing device that switches between a knob and slider. It enables three different interactions (sliding, clicking, and rotating) on one device. It is originally designed for professional users such as sound engineers who use lots of sliders and dials. KnobSlider aims to bring flexibilities of interfaces while keeping dexterity with physical devices, rather than to use flat touch screens with poor haptic feedback. KnobSlider allows eyes-free, mobile control.
