Subject: Haptic-audio interaction desing (HAID) 2010 - First call From: Stefania Serafin <sts@xxxxxxxx> Date: Tue, 23 Feb 2010 08:01:43 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--Apple-Mail-93-838494538 Content-Type: text/plain; charset=WINDOWS-1252; format=flowed; delsp=yes Content-Transfer-Encoding: quoted-printable Apologies for cross-posting Dear all, I would like to announce the following event: Fifth International Workshop on Haptic and Audio Interaction Design =20 (HAID). September 16-17 2010 in Copenhagen, Denmark. Deadline for full paper submissions - 30th April 2010 www.media.aau.dk/haid10 Technologies to enable multimodal interaction are now sufficiently =20 mature that research is turning away from pure hardware development =20 and looking towards interaction and design issues to improve usability =20= and the user experience. Robust solutions exist to display audio and =20 haptic feedback in many forms =96 for instance as speech and non speech =20= sounds and through tactile and force feedback sensations. Furthermore, =20= it has been demonstrated that the novel interactions supported by =20 these modalities can confer benefits for all users. However, many =20 questions remain concerning the appropriate use of haptics and audio =20 in interaction design: how can we design effective haptic, audio and =20 multimodal interfaces? In what new application areas can we apply =20 these techniques? Are there design methods that are useful? Or =20 evaluation techniques that are particularly appropriate? HAID10 is a direct successor to the successful workshop series =20 inaugurated in Glasgow in 2006, in Seoul in 2007, in Jyv=E4skyl=E4 in = 2008 =20 and in Dresden in 2009. The aim of HAID10 is to bring together =20 researchers and practitioners who share an interest in finding out how =20= the haptic and audio modalities can be used together in human computer =20= interaction. The research challenges in the area are best approached =20 through user-centred design, empirical studies or the development of =20 novel theoretical frameworks. We invite your papers, posters and demonstrations on these topics, and =20= look forward to seeing you in Copenhagen in September 2010! Topics Contributions are welcomed in (but not limited to) the following areas =20= (please note that in all of these areas both theoretical and empirical =20= approaches are encouraged): - Novel haptic, audio and multimodal interfaces and interactions - Evaluating multimodal interactions, especially in real contexts - Design principles for multimodal user-interfaces - Multimodal visualisations - Affective roles of haptics and audio in interaction - Cross-modal interactions - Auditory and haptic displays for visually impaired people - Safety critical multimodal applications (monitoring, controlling, =20 alarming) - Designing haptics and audio for touch screen - Multimodal gaming and entertainment - Interaction in physical exercise - Collaborative multimodal systems - Mobile multimodal interactions - Emulation and simulation of real world with audio-haptic design - Novel systems and interactions using other modalities (e.g. taste, =20 smell) Publication The proceedings will be published by Springer in their LNCS journal =20 series. Important Dates Deadline for full paper submission: April 30th Notification of acceptance: May 28th Final camera ready due: June 18th Poster and demo submission: June 1st Notification of poster and demo acceptance: July 1st HAID 2010: September 16 and 17, Copenhagen, Denmark CONFERENCE CHAIRS Rolf Nordahl, Aalborg University Copenhagen, DK Stephen Brewster, University of Glasgow, UK SCIENTIFIC PROGRAM CHAIRS Federico Fontana, University of Verona, IT Stefania Serafin, Aalborg University Copenhagen, DK POSTERS AND DEMOS CHAIRS Sofia Dahl, Aalborg University Copenhagen, DK Kristina Daniliauskaite, Aalborg University Copenhagen, DK PROGRAM COMMITTEE Ercan Altinsoy, Dresden University of Technology, Germany Federico Avanzini, University of Padova, Italy Stephen Barrass, University of Canberra, Australia Durand R.
