R-1 Mouse-Like Analog Radio

An analog radio is one of the most important products for blind people. Ilgu Cha from the Royal College of Art in London is an award winning designer who has developed the R-1 analog radio, which can be operated by anyone with basic motor functions.

The volume is adjusted by sliding the gizmo up or down and the station can be switched by sliding it from left to right. Cha used the behavior of how people manipulated rather than burying all of interaction in to the product. Therefore, adjusting radio to the right station would require a new kind of manipulation rather than simply tuning a knob. The R1 was designed for the blind to control the radio more intuitively by using a wheel structure, where the user can control the radio by physical movement. The R1 allowed users to turn gadget on or off and to control volume and tuning simply by physically rolling the radio forward, backward and sideways.
