Adjusting virtual worlds to real world feedback limitations while using quadcopters [article]

Matthias Hoppe, Universität Stuttgart, Universität Stuttgart
The current development of Virtual Reality technologies are mostly focused on providing deeper immersion by improving displays and 3D audio quality. The influence of interaction and haptic feedback is often neglected. State-of-the-art technologies are still adapting gamepads and forcing the user to hold controllers that give haptic feedback by simply applying vibration. Such interaction and haptic feedback methods are therefore inducing less presence on the user. We suggest a method of

We reviewed haptic quadcopter feedback by conducting three user studies to validate the quality of quadcopter feedback, explore the ability to simulate various objects and explore additional feedback methods for simulating objects with extreme properties. We found that haptic feedback provided by quadcopters in combination with hand tracking is a feasible improvement of providing feedback. Furthermore, haptic quadcopter feedback is well received while simulating interaction with small, light object or objects with a soft surface. In cases of non-moving, solid objects additional feedback methods can be applied to increase the resistance felt by the user. While limitations have to be kept in mind when it comes to designing virtual worlds to include quadcopter feedback, we see it as a suitable way of providing flexible, three-dimensional, hands-free, haptic feedback.
