The application of visual and auditory senses into virtual reality is easily taken for granted, but the sense of smell has been largely ignored. But many researches have shown that olfactory stimulation in virtual environments can increase the immersion and reality. In practical virtual reality, the use of scents is not always able to increase the immersion and reality. An ill-matched scent can decrease the reality. To solve this problem, we developed scent devices that can adjustable scents and scent intensity in order to display a well-matched scents in virtual reality. And we propose simple and practical way to program specific location to display scents and developed API function to control a developed scent device at virtual reality software.

Scent diffuser using micro-pore piezo actuator achieved a commercial success because of its cheap production cost, but it is easy to be use for IT-based contents due to difficulty of scent intensity control. To solve this problem, we control the emission amount of scent diffuser by changing amplitude and frequency of input voltage applied to micro-pore piezo actuator. And, we analyzed the effect of den-sity of cotton core on emission amount and a relationship between hole-size of mesh in piezo actuator and viscosity of scents to design a mechanically optimal scent device.
