Active and Passive Mediated Social Touch with Vibrotactile Stimuli in Mobile Communication

“…We explored user-defined gestures for MST on the touchscreen of smartphones in our previous study [9].…”

“…In [9], we proposed classifications based on movement forms. We mentioned in [9] that "Movement forms indicate the trajectory and dynamics of hands/fingers movement" [22].…”

“…Firstly, we introduced vibrotactile stimuli for MST based on a previous study [7]. Then, we described the gestures of MST for the sender and the receiver based on user-defined gestures for MST from [9].…”

“…We selected 11 MSTs (nuzzle, poke, press, pull, rock, rub, shake, tap, tickle, toss and tremble) from a Touch Dictionary [9,10]. We did not consider MST with multi-point touch in this study since there were many challenges when designing user experiences of multitouch interfaces [11].…”

“…Therefore, differences in perceiving MST with vibrotactile stimuli may occur when gestures are different, especially when complex gestures are applied. For example, in repetitive gestures such as "shake" [9], a sender moves their fingers back and forth on the touchscreen to send the touch [9]. The vibrotactile stimuli will be along with their fingers' movements.…”
