Touch has been known in the physical world to increase early trust.
For example, fathers who touch their kids when
chatting with them might earn their trust quickly [4]. With
the advance of haptic interface in CVEs, virtual touch can
be supported in 3D e-commerce environments. A number
of researchers have designed systems that allow two users
to interact via virtual touch in the CVEs. Kim and
colleagues [11] have developed haptic interaction platforms
that allow multiple users to experience virtual touch while
solving numerous difficulties relating to network delay. Ho
et al. [6] ran experiments in which participants used
collaborative haptic devices, and could feel the digital
avatars of one another while performing tasks.
