Ein benutzerfreundlicher Fahrkartenautomat - ergonomische Grundlagen und ihre Umsetzung in die Praxis.

The use of ticket slot machines has been improved by developing principles for the design of the front-plates giving user guidance.

The new panel based on the operating sequence diagram is being presented. (IITB)
