Modifying Gesture Elicitation: Do Kinaesthetic Priming and Increased Production Reduce Legacy Bias?

A common issue in gesture elicitation studies is that participants are influenced by interaction with digital products, imitating touchscreen gestures or WIMP icons. In our study, we adapted and experimentally tested two of Morris' et al.'s suggestions for reducing legacy bias: increased production of gestures and covert kinaesthetic priming. Our findings indicate that the practical effectiveness of these strategies might be limited, given we only found medium effect sizes and a wide variance between participants that overshadows any effects. Our work contributes to reflection on, and indirectly, by experimentally testing potential variations, to future improvements of the gesture elicitation method.
