“…By finding that providing such feedback can act to discourage certain consumer actions, this work extends research on multisensory design as a means of providing negative feedback ( Faust and Yoo, 2006 , Ho et al, 2006 , Jiang et al, 2005 ). Finally, although prior work has explored vibration intensity in order to determine at what thresholds people can detect different frequencies (e.g., Morioka and Griffin, 2005 , Oey and Mellert, 2004 ), HCI researchers are only beginning to explore how vibration intensity affects people’s psychological responses ( Abdullah et al, 2018 , Yoo et al, 2015 ). Some consumer work has explored responses to differing frequencies of auditory feedback ( Lowe, Loveland, & Krishna, 2018 ), but consumer studies using haptic feedback have only used a single vibration intensity ( Hadi & Valenzuela, 2019 ).…”
