This book constitutes the refereed proceedings of the 6th International Workshop on Haptic and Audio Interaction Design, HAID 2011 held in Kusatsu, Japan, in August 2011. The 13 regular papers and 1 keynote presented were carefully reviewed and selected for inclusion in the book. The papers are organized in topical sections on haptic and audio interactions, crossmodal and multimodal communication and emerging multimodal interaction technologies and systems.

outlines directions for future work. 2 Methods The experiments described in this paper collected subjects’ open-ended, subjective responses to a typical interaction with a PHANToM Omni haptic device. The interaction is touching a virtual sphere displayed both on an ordinary computer monitor and in a 3D haptic space by the Omni device. The standard SDK (OpenHaptics Toolkit [10]) was used to create the software used in the experiment. For each experimental session, settings were randomized for

better than the other two conditions: the stiffness change along lateral motion and comparing objects with different stiffness. The mean value of the JND for the nonlinearity case (Continuous Pressure) is 5.23±3.01%, while the Discontinuous Pressure and Continuous Lateral contacts have a mean JND of 12.91±6.93% and 15.77±9.59% respectively. 30 6 U.

Various improved vocoders such as the cepstral vocoder [10] and LPC vocoder [11] have been proposed for high-quality synthesis. TANDEM-STRAIGHT [12], which is an improved vocoder, can synthesize the voice that sounds as natural as the input voice, and manipulate the pitch Vocal Manipulation Based on Pitch Transcription Preprocessing 55 Spectral envelope

understanding of music. 3 Experiment Two groups of five subjects based respectively in Italy and India, including two teachers of music and three practitioners, had to choose the ethnic origin of four scales by relying on vibrotactile perception through the hands of the vibrations coming from an harmonium manufactured by Orient. By making use of the setup in Fig. 4, which included a pair of Senheiser in-ear headphones, subjects were protected from visual and auditory cues. In parallel they

that one is more physically correct could add a bias, and the order of appearance was balanced. The objective was to find the harder patch. Its correct location was randomized and the selection was done by pressing a button on the haptic instrument on the chosen patch. As an initial search for an entry level the task was first very simple, the harder surface being 100% stiffer than base stiffness. This was then quick lowered by halving the difference for every second right answer until two consecutive
