We have featured a few different radio which unique way to control them. Like the Rolling Cube Radio but this innovative concept for blind people designed by South Korean-born Il-Gu Cha allows you to adjust the volume and tuning by rolling the radio backwards and forwards and left to right.
An analog radio is one of most important product for a blind people. In the using a behavior of how people manipulated rather than burying all of interaction in to the product. So adjusting radio to the right station would require a new kind of manipulation rather than simply tuning a knob.
‘R1’ has designed for them to control the radio more intuitively. By using a wheel structure 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.
Functionally, by using bevel gear system, I could increase a tuning range more than four times wider than before. There were too many channels in a narrow display before.
