From Initial Encounter with Mid-Air Haptic Feedback to Repeated Use: the Role of the Novelty Effect in User Experience

Journal Contribution - Journal Article

Mid-air haptic (MAH) feedback is an interesting means to provide augmented haptic feedback for gesture-based technology as it enables a sense of touch without physical contact with an actuator. Although quite some work already investigated the user experience (UX) of MAH feedback during initial encounter, we are not aware of studies testing the UX after repeated use, with regard to both pragmatic and hedonic UX, as well as emotional reactions. In this article, we tested how the UX of MAH feedback changed over the course of five weeks by collecting both questionnaire as well as interview data of 31 participants. Our results showed that MAH feedback significantly increased the enjoyment, engagement, valence and arousal of the emotional response. However, the added value of valence was due to a novelty effect as it was only significantly elevated during initial use, and not after repeated use. Interestingly, the added value of MAH feedback in terms of enjoyment, engagement and arousal remained elevated over the course of five weeks. Moreover, the interview data hinted at substantial individual differences underlying the global trends from the questionnaire data, showing the importance of combining quantitative and qualitative data when testing the UX of MAH feedback.
