Leonard Verhoef

Leonard Verhoef (@leonardverhoef) talks about the Dutch Railways ticket vending machine (aka NS Kaartautomaat). Leonard has been involved with the ticket vending machines since 1985, when the 80 destiny button machine didn’t take the psychology of the user in account. His first psychological sketch for the current touch screen version dates from 1999 and hasn’t changed since then. It can´t change because the biology of mankind hasn’t changed and wil not change in 100.000 years.
