Abstract
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px 'Times New Roman'} In Japan, accidents in the factory are constantly becoming serious problems as a result of lack of technology transfer due to mass retirement of skilled technicians in machine tools. As a solution, this study proposes immersive VR content for work support using Head Mounted Display (HMD) and haptic device. This is a system to reproduce machine tools with dangerous handling such as milling machines and lathes in the VR space and present arbitrary feedback to the fingertips with a haptic device when performing erroneous work or fine work, thereby safely carrying out work training support. In this study, HMD and haptic device were used in combination as a method to feedback to users, so that more realistic work can be done in virtual space. VR environment was created with Unity that can manipulate machines in Virtual Space. Leap Motion was used to track and display subjects own hand in VR environment. Haptic device was made using Arduino and vibration motor to present feedback on fingertips. As a result, the tracking of the hand using Leap Motion when gloves are used together shows that the detection rate greatly differs depending on the material of the glove. With VR environment and vibration feedback, we showed the effectiveness of intuitive operation similar to reality.
Highlights
According to the Goldman Sachs Global Investment Research Division in the global AR/VR market, the AR/VR market will expand to about US $95 billion in 2025 in the future, and it is said that there is a possibility of forming a market as the third platform following the PC and smartphone
In 2016 it is said that this year was “VR Gannen”, the first year of VR due to the fact that low-cost head mounted displays, essential for VR, came out on the market (2)
A system using VR and Head Mounted Display (HMD) so far required a special system at a high cost and was only accessible for large companies, but in recent years it was commercialized at a reachable price range and high quality for general consumers due to popularization of HMD, and it became an environment where consumers can enjoy VR comfortably

A system using VR and HMD so far required a special system at a high cost and was only accessible for large companies, but in recent years it was commercialized at a reachable price range and high quality for general consumers due to popularization of HMD, and it became an environment where consumers can enjoy VR comfortably. Since it can introduce VR at low cost, it attracts attention as a sales tool for commercial use such as customer service and tourism. Since haptic feedback can present various kinds of feelings such as soft, sharp, hard, dull, etc., reproducing the unique feeling possessed by experienced technicians and aim to improve the efficiency of acquiring skills by having young engineers experience themselves can lead to the transfer of technology
