Doubtlessly I am a bike lover. I enjoy the 2 dimentional freedom which give me the exact extention and resolution of scenery where I am living or will explore without further expenses. Though tons of exordinary bike interfaces happen in art community, tech community, maker community and so forth, yet I still wanna build one interesting bike interface myself.
I found a nice connection: the keyboard, our daily intimate interface. In order to create some new typing experience, I have the will to mapping the different functionalities of bike to a motion of pointer for typing on an old keyboard.
Here is my sketch. The fundamental solution is to use 2 dimentional cam mechanism with bevel gear. The handbrake can define as PRESS and DELETE.
one cycle of the cams’ motion (two dimentional)
compound cam design
Yet I found the fitness bike, which has only one dimention of motion yet no worries about hanging the wheel up.
Last but not the least, some references:
