Abstract

In this paper we report on the process and results of creating a questionnaire-based metric for experience of form. The questions for the metric were chosen on the basis of an expert evaluation and short iterative pilot tests, with the emphasis on ergonomics and the usability of the metric for both the commissioner of the questionnaire and the subjects filling it in. Basic questionnaire design guidelines were applied for building a logical and understandable structure of questions and the process for the evaluation event. The metric was finally adapted for the evaluation of four everyday drinking glass designs and tested in a small field study with 20 subjects. The usability of the questionnaire was evaluated according to chosen parameters for speed, understandability, and subjective experience, while usefulness was evaluated in terms of how well the metric could highlight defining characteristics for the objects under evaluation. Overall, satisfactory values were received for all parameters defined, and the questionnaire did manage to bring out defining characteristics for the glasses in the context of a rapid implementation.
