Using QUIS as a Measurement Tool for User Satisfaction Evaluation (Case Study: Vending Machine)

Today, industrial designers believe that their products are not only designed to meet the needs of customers, but also to create a new experience in users. Since the physical performance of products have been solved by technological advances, investigating and providing the customer satisfaction and addressing customers' demands and requirements in long term design and manufacturing the products can lead to the increase of loyalty and success of companies. Designers have begun to find a sense of connection between people and products to satisfy the people. Regarding these issues, in this article, user satisfaction and experience of the use of vending machine were measured by satisfaction questionnaire (QUIS) which is a designed measurement tool to assess a computer user's subjective satisfaction by the human-computer interface. 32 students (19-35 years old) from Tehran’s universities (Tehran Polytechnic, Iran University of science and technology, university of Tehran) were participated in this study. The results of the questionnaire were analyzed by SPSS. Finally, the results of this analysis are defined as the criteria which can be used in designing future spaces to create pleasant feeling in users.
