The Benz museum in Ladenburg is a regular haunt of mine. In walking distance of my house I can see one the of the first cars ever made.
It is one of the finest collection of vintage and significant cars as you will find anywhere, other than at the other Benz museum in Stuttgart. It is my sad affliction to think about software design at the weekends, and the Benz museum provided some ideas on usability.
This is an early French racing car. a 1921 Amilcar. 28 horsepower, 908cc motor.
This is the steering wheel of a formula one championship winning car. Comment below if you can tell me whose.
It would overwhelm most of us, but for the best drivers in the world, every switch is vital and a lot of thought went into its layout. It is a User interface built for one.
The problem with a lot of business application software is that it has as many buttons and switches as the example above, but most users would be better of with the Amilcar layout. Most users just want to get in and drive. It is only when you really get to know your user that you can actually design something that works for them.
On another note, It is a very child friendly museum.
