Bringing Them Under the Same Roof The Haptic and Audio Interaction Design workshop series is now in its third year. These workshops have already demonstrated a clear need for a venue in which - searchers and practitioners in these areas gather together under the same roof. Three years have also shown clear developments in the approaches taken - with the benefits of combining haptics and audio shown practically and conceptually in this year's - pers. In other words, it seems that when there is interaction between audio and haptic researchers, they really learn from each other and multimodal approaches emerge. There are many good reasons for using haptics and audio together. There are the practical needs in application development. Mobile devices are an obvious example - while the device is small in size and is used on the move, interaction cannot rely solely on visual display. On the other hand, the development of applications for visually impaired people makes it necessary to learn how to design non-visual user-interfaces for different situations.
