Concept Evaluation
Last Updated:
Evaluation of conceptual spray system designs
The study aimed at evaluating four different washing system concepts for dishwashers based on the satisfaction criteria that were specified in the previous studies. As a result of the study, recommendations for improvements of the concept designs were suggested as well as recommendations related to new directions that can be considered for new designs.
User Acceptance Analysis for Three Dishwasher Concepts Based on Contextual Research
The aim of this study was to evaluate three dishwasher concept designs developed by the firm by considering how they were perceived and to what extent they were accepted by the user. At the first stage, the participants' daily practices and habits regarding dishwashing were explored and their concerns and expectations were questioned. After that, the three concept designs were installed in the participants' houses to be tested for a period of eight weeks. During this period usage of the products and the degree of user adaptation were evaluated. At the end, possible design requirements were identified as the outcome of the project. Besides the field study, which was carried out in the actual usage context, a questionnaire with 103 respondents was conducted with the purpose of identifying priorities of the users regarding dishwashers.
Investigation of Changes in Dishwasher Rack Design
In this study, a new rack design prototype was evaluated with the previous rack systems, in the laboratory environment. The study was conducted with 30 users with the success scale which was developed during the previous studies. The success of the prototype was evaluated according to the targeted qualities.
Expert Analysis and Interface Modeling for Dishwashers Based on an Interface Concept
In the early design process of Arçelik 62191 – ‘Techtouch’ dishwasher, interface design drafts were evaluated with expert analysis and the preceding design improvements were overviewed before the prototype development. The dishwasher interface differed from conventional interfaces with its automatic program setting process and the design requirement to use a limited alphanumeric display for informing the user about the program flow. Following a careful analysis of the program setting and use process, the design recommendations were classified according to the technical limitations and the resulting interface was applied into prototypes by the firm for the user study in the real context.
Interface Design for Two Arçelik Dishwasher Models Based on Product Concepts
Based on the firm’s marketing objectives, design alternatives for the ‘single button’ dishwasher interface concept were developed. Two interface alternatives, which differed in functionality and interface elements, were proposed for upper and lower market segments.The meaning of ‘single button’ concept was examined in the initial stage and the functional specifications for both models were defined. Cognitive walkthrough was used as a method to develop functional flow diagrams and the resulting interface alternatives were modeled in detail.
