Abstract
Gesture elicitation studies are a popular means of gaining valuable insights into how users interact with novel input devices. One of the problems elicitation faces is that of legacy bias, when elicited interactions are biased by prior technologies use. In response, methodologies have been introduced to reduce legacy bias. This is the first study that formally examines the production method of reducing legacy bias (i.e., repeated proposals for a single referent). This is done through a between-subject study that had 27 participants per group (control and production) with 17 referents placed in a virtual environment using a head-mounted display. This study found that over a range of referents, legacy bias was not significantly reduced over production trials. Instead, production reduced participant consensus on proposals. However, in the set of referents that elicited the most legacy biased proposals, production was an effective means of reducing legacy bias, with an overall reduction of 11.93% for the chance of eliciting a legacy bias proposal.Keywords
