Task Analysis and Usability Analysis of a Ticket Machine

Scholarly Research Paper from the year 2008 in the subject Ergonomics, grade: 1,3, University of Derby (Institut für Psychologie), course: Ergonomics, language: English, abstract: This report examines the car park ticket machine (TM). The Hierarchical Task Analysis (HTA; Sheperd, 2000; cited in Mills, 2007) is used as a framework: Firstly, psychological issues related to using the TM are discussed. Secondly, an usability analysis of the TM is conducted, whereupon principles of usability (Jordan, 1998) are applied. The result is that the design has major issues. Subsequently, an improved design is sketched out - considering identified issues. Finally, an evaluation method for the redesign is introduced.
