This study explores improving the quality of experience from two perspectives for a new concept of the stereohaptic vibration display proposed in our previous study. Stereohaptic vibration is a technology that localizes a vibration source at an arbitrary position outside the body, similar to stereophonic sound, and is realized by distributing the amount of perceived vibration to multiple oscillators using a novel vibration modulation technology for arbitrary vibrations, including the auditory range.
To further improve the quality, first, the relationship between the frequency components of vibrotactile stimuli and external localization will be clarified, and the required specifications of the optimal vibration device will be clarified. Second, from a multimodal perspective, we will investigate the synergistic effects of stereohaptics and audiovisual localization performance and the improvement of realism. We also challenge stereohaptics with multiple vibration sources and verify the improvement of the sense of presence. We will provide a general-purpose fundamental technology for tactile displays that can be widely used in the deep SHITSUKAN field.
