Finger switch type hand shaking sensor for VR-HMD

Wearing a virtual reality head mounted display (VR-HMD) provides a closed space for a user, resulting in an enhancement of their immersive sense. However, the user is unable to see anything in their front. In such a situation, the user might hit objects in the VR room, which can be dangerous. To avoid this situation, a simple sensor device can be integrated into the VR-HMD. In this study, an attempt has been made to fabricate a finger-switch-type hand sensor device and integrate it into the VR-HMD. By shaking one’s hand, the user can determine the positions of objects shown on the VR display, and thus avoid bumping into them. Furthermore, by folding their finger, the function of turning off the light source has been added to the device. Consequently, the user can play the VR game comfortably.
