We propose a head-based multi-directional force feedback in a virtual environment. We integrated four ducted fans into a head-mounted display to present force to the user’s head. Through a technical evaluation, we revealed the presentable power, sound level, and latency of a ducted fan. In the first study, we investigated the minimum force that a user can perceive in different directions. The result shows the user’s perceivable range of the force that our device could provide. The second study evaluated the effect of leveraging force feedback through an immersive flight simulation. The result indicates that our technique significantly improved user enjoyment, comfort, and visual-and-haptic consistency, and reduced simulator sickness.
