Dilemmabox brings tactile upvoting

Here’s a fun art installation which you might run into downtown. It’s called the Dilemmabox and lets you pull a rope to up or down vote a question. [Christoffer Lorang Dahl] realized that touchscreens are wiping out a lot of really fun user interfaces of yore. He incorporated the two hanging rope inputs as an homage to doorbell ropes.

The built process works much like a laptop-to-digital photo frame conversion. The first step is to liberate the LCD screen from the laptop body. Both are housed in a wooden box, with a window cut out to show the screen. The mechanically clever part is the rope pulls. They’re both just pressing a key on the keyboard in a roundabout sort of way. [Christoffer] attached a smooth hemispherical piece to two keys. The ropes are connected to wooden levers which are held in place by springs. They rub on the hemispheres just enough when passing by to register a keypress.

The photo above was taken during the Dilemmabox’s brief appearance at a shopping plaza in Oslo.
