ABSTRACT
Somatosensory stimulation associated with facial skin deformation has been developed and efficiently applied in the study of speech production and speech perception. However, the technique is limited to a simplified unidirectional pattern of stimulation, and cannot adapt to realistic stimulation patterns related to multidimensional orofacial gestures. To overcome this issue, a new multi-actuator system is developed enabling one to synchronously deform the facial skin in multiple directions. The first prototype involves stimulation in two directions and its efficiency is evaluated using a temporal order judgement test involving vertical and horizontal facial skin stretches at the sides of the mouth.
