Abstract = {Conducting gesture elicitation studies (GES) in personal spaces such as smart homes is crucial to achieving high ecological validity of elicited gestures. However, supervising such studies is considered intrusive and negatively affects the results' quality. The alternative is to conduct unsupervised GES under similar conditions, but more side-by-side comparisons documenting the similarities and differences between both approaches are necessary. Consequently, we need more data describing the preferred approach and whether the differences or similarities in the results are so significant to cause concern. This research distributed a DIY observation kit, which 30 participants assembled and used to propose gestures for controlling elements in a smart living room using a pillow's surface, with and without supervision. Our results show that gestures from supervised and unsupervised studies differ in quantity and max-consensus but not in gesture Agreement Scores. Our results also show that participants preferred conducting unsupervised studies but proposed fewer gesture sets in this condition.}
