Outline of Final Research Achievements

In this study, we are attempting to obtain scientific findings, which are available for new haptic devices using pseudo-haptics and velvet hand illusion (VHI). Due to this, we will develop three haptic devices to investigate brain activity invoked by virtual reality (VR) using brain machine interfaces (BMI) such as ElectroEncephaloGram(EEG), Near InfraRed Spectroscopy(NIRS), and HemoencEphaloGraphy (HEG). Our achievements are summarized as follows: 1) compressible force for the tactile pad of the manipulator typed haptic device should be controlled within the range between 1 and 2 N to obtain virtual hardness introduced by pseudo-haptics; 2) the alpha-wave amplitude decreased when searching and extract contour of virtual object through the tactile mouse for fingertips; 3) virtual smooth surface presentation is possible using VHI even if the tactile mouse presenting convex-and-concave pattern is applied as the haptic device.
