A Multimodal Interaction Design Guidelines for VR Foot Reflexology Therapy Application

The proliferation of multimodal interaction research have presented numerous advantages which include enhancement of realism, increased efficiency in user task performance and the achievement of an interactivity that is relatively identical to the conventional human to human interactions. Haptic, visual, and aural interactions have been widely utilized and applied in various domains ranging from military and scientific visualization realms into more multidisciplinary areas, such as art and culture, education, archeology, and complementary medicine. In Virtual reality stress therapy application particularly in the proliferation towards the virtualization and simulation of the traditional foot reflexology therapy, little is understood on the haptic, visual and aural interactive nature of the therapy and to what extent they contribute in the patients' relaxation and stress relief, which hinders the system developers from obtaining the appropriate system design requirements for foot reflexology virtual stress therapy applications. This paper presents an exploratory study that examines from both the patients' and practitioners' perspective, the haptic, visual and aural interactive nature in foot reflexology domain since the practices promote relaxation and stress relief. The study explored 2 traditional foot reflexology sessions; audio recorded semi-structured interview was used to collect data from the participant's while the session was going on for analysis. The study findings presented the haptic, visual and aural interactive nature involved from the patients' and practitioners' perspective, and a higher level design requirements for the haptic, aural, visual and general interactivity extracted from the study findings as well as from literature. Implications for future research are also discussed.
