Factors Affecting the Results of Gesture Elicitation: A Review

Gesture elicitation is a fundamental method for constructing gesture-based interactive systems. Existing research has shown that this method allows users' knowledge to serve as a design basis, minimizing biases that may occur from relying excessively on an expert's preference. However, how to conduct effective gesture elicitation studies remains an uncertain and open-ended issue. Through a thorough literature review, this study aims to identify important aspects that have significant impacts on the implementation of the elicitation study. The main findings of this paper are as follows: gesture elicitation has become a commonly used tool in research and practice; factors such as participant selection, referent form, and research environment can significantly affect the study results; further investigation is needed to explore how to utilize this tool more effectively and reproducibly, for example: developing more standardized research protocols, establishing consensus on methodology of calculating and reporting agreement scores, gaining a deeper understanding of the factors that influence the results.
