    Comparing Auditory and Haptic Feedback for a Virtual Drilling Task
    (The Eurographics Association, 2012) Rausch, Dominik; Aspöck, Lukas; Knott, Thomas; Pelzer, Sönke; Vorländer, Michael; Kuhlen, Torsten; Ronan Boulic and Carolina Cruz-Neira and Kiyoshi Kiyokawa and David Roberts
    While visual feedback is dominant in Virtual Environments, the use of other modalities like haptics and acoustics can enhance believability, immersion, and interaction performance. Haptic feedback is especially helpful for many interaction tasks like working with medical or precision tools. However, unlike visual and auditory feedback, haptic reproduction is often difficult to achieve due to hardware limitations. This article describes a user study to examine how auditory feedback can be used to substitute haptic feedback when interacting with a vibrating tool. Participants remove some target material with a round-headed drill while avoiding damage to the underlying surface. In the experiment, varying combinations of surface force feedback, vibration feedback, and auditory feedback are used. We describe the design of the user study and present the results, which show that auditory feedback can compensate the lack of haptic feedback.

    Floor-based Audio-Haptic Virtual Collision Responses
    (The Eurographics Association, 2012) Blom, Kristopher J.; Haringer, Matthias; Beckhaus, Steffi; Ronan Boulic and Carolina Cruz-Neira and Kiyoshi Kiyokawa and David Roberts
    Virtual collisions are considered an important aspect of creating effective travel interactions for virtual environments; yet, they are not yet well understood. We introduce a new floor based audio-haptic interface for providing virtual collision feedback, the soundfloor. With this device, haptic feedback can be provided through the floor of a projection VR system, without disturbing the visual presentation on the same floor. As the impact of feedback is not yet known for virtual travel, we also present a series of experiments that compare different feedback methods coupled with classic collision handling methods. The results of the experiments show only limited benefits of collision handling and of additional feedback for performance. However, user preference of context appropriate feedback is evident, as well as a preference for the floor based haptic feedback. The experiments provide evidence of best practices for handling virtual travel collisions, namely that context appropriate feedback should be preferred and that quality sounds are sufficient when haptics cannot be provided.
