Clicking Push Button

Train DoorÂ


Product: Button
Function: Traindoor opening

Main Interaction: Pushing
- User pushing plastic button. The button, about 3cm in diameter is pushed about 5 mm into a metal housing.
- It's a short push with one finger and a fast release. This small action initiates the moving of a heavy door.
- Only one finger is needed to move a large thing
- the resistance while pushing is bigger then expected for such a "small" button (fits with the weight of the door that will be opened with)
- the surface is glossy

Main Sound: click
- it's a dry, technical sound
- a spring inside causes a double click (press and release), and a short echo
- sound seams to be longer than interaction
- the surface can't be heard
- the button is "isolated"; the material where it's mounted doesn't act as a resonance body

Context: Button to open the train door. I'ts placed beside the door.
The train was waiting at the Main Station in Zürich at track 18, which is at the border of the Train Station, therefore it was not too load, but still noisy. We heard cars, people talking, announcements from loadspeakers and the sound of other trains departing or arriving.
The button is used by everyone who wants to enter the train, every age, commuter as well as tourists.



Product: Trash Basket
Function: Throwing away something
Main Interaction: Throwing something into Basket
- Person prepares the trash

Product: Handle
Function: Mechanical way to open the train door
Main Interaction: Pulling

Interaction
- Grab the handle with the right hand (in left-traffic countries!)
