Feel the weight in your hands.
The Korea Advanced Institute of Science and Technology (KAIST) experimented with various forms of force feedback for virtual reality (VR) applications, introducing the Wind-Blaster peripheral last year. It was focused on modeling force effects. Recently, the institute presented its latest development – Aero-Plane, designed for bulk modeling.
While Aero-Plane tied two fans to the user’s hand, for direct and reverse air explosions, Aero-Plane takes these fans and attaches them to the controller device, providing a continuous stream of air flow. This should help create the illusion of weight in the virtual world, as well as the displacement of the center of gravity.
Traditional tactile devices, such as the current range of motion controllers for the Oculus Rift and HTC Vive, have a basic vibration function, giving players more connectivity
with game experience. Aero-Plane takes it a step further, so when you lift an item, it will appear heavy, or when carrying an unstable load, the weight may move, which must be compensated.
In the KAIST demo video, the team uses a ball rolling in a 2D plane, which the user can then force to roll in one direction. The developers explain that the Aero-plane is: “a manual controller with power feedback based on two miniature fans that can display a weight shift of up to 14 N in 0.3 seconds.”
Obviously, at this stage, Aero-Plane is still an early prototype, rather bulky and with a lot of cables coming from it.
