il gu cha: R1 radio

tuning is done by moving the radio from left to right and volume is controlled by rolling the radio forward and backward

R1 radio by il-gu cha is an analog radio which requires one to tune the radio by physically rolling it on a surface. studying how people manipulate rather than bury their interactions with a product, the radio brings about a new kind of behavior between itself and the user.

by using a bevel gear system wheel structure, one can control the radio through physical movement. the R1 allows users to turn the gadget on or off, and control volume and tuning simply by physically rolling the radio forward, backward and sideways.

you can view a video of how the R1 functions here.

  • Conceptually, outstanding! You might need more ground clearance for better sound (bigger wheels). I wish the behavioral translation also took place in an ergonomic translation. In other words, it would have been nice to see a form that was intuitive to use by looking at it as well as being a form that related to either Radio or Hand.

  • I agree with Frank. Also, sorry to say it but i saw something similar in the 1960s when i was a kid. I dont know who made it but although the form was different it functioned the same way. Its not new.

  • Speaker on the base eh? Interesting idea………

  • How do the wheels in the opposing plane keep from catching on the surface? Why would the speaker be on the bottom? I don’t understand the reasoning behind this design.
