We named objects with and without haptic feedback as ''real entities and ''clones respectively, and evaluated the impression of the VR game experience under the various temporal presentation patterns of them. The results showed that the players' surprise and satisfaction were higher when real entities and clones were mixed than when only real entities or clones appeared. In addition, a sudden change in the frequency of appearance of real entities brought an impression impact.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing -> Human computer interaction(HCI); Virtual reality; Computer systems organization -> Robotics;Human centered computingHuman computer interaction(HCI)Virtual realityComputer systems organizationRobotics10.2312/egve.2022131149-502 pages
