“…The toy creates an engaging tactile experience by utilizing the rapid change in the reaction force when the rubber hemispherical dome is pressed and buckled by a fingertip. In addition to toys, mechanical switches or buttons, such as those used inside automobiles and keyboards, are associated with haptic sensations that affect user satisfaction (Gaspar et al, 2017;Hatzfeld et al, 2010;Kim and Lee, 2013;Li et al, 2013;Schütte and Eklund, 2005;Simon and Jörgen, 2005;Stamer et al, 2020;Vieira et al, 2017;Wellings et al, 2010;Zheng et al, 2022). Singular patterns of reaction forces and sounds (Burnett and Irune, 2009;Miyari et al, 2022) caused by the buckling or abrupt restoration of spring systems or mechanical levers determine the haptic comfort when the switches are pressed.…”

Mechanical buckling of a switch or button produces an attractive sensation of touch; however, a method to optimize the haptic pleasantness caused by buckling has not been established and well demonstrated. In this study, we optimized a popping elastic dome toy that provides pleasant haptic sensations when pushed or buckled. Toys with different physical parameters were manufactured following the Box-Behnken design, and their comfort was evaluated by the users. The design parameters that maximize haptic pleasantness were determined using the response surface method. The optimally designed popping toy was equally as comfortable as the best one in the initial specimen set. Further, haptic pleasantness was found to be largely determined by the ease of pushing and haptic feel at the moment of buckling. This approach is expected to improve the haptic sensations of various commercial products such as mechanical switches.
