The international Gesture Workshops have become the leading interdisciplinary events for dissemination of the latest results on gesture-based communication. The goal of these workshops is to bring together researchers who want to meet and share ideas on advanced research on gesture related to multidisciplinary scienti?c ?elds. Depending on the ?elds, the objectives can be very di?erent. While physiology and biomechanics aim to extract fundamental knowledge of physical gesture, computer sciences try to capture di?erent aspects of gesture and extract features that help to identify, interpret or...

The International Gesture Workshop is an interdisciplinary event where researchers working on human gesture-based communication present advanced research currently inprogressandexchangeideasongestureacrossmultidisciplinaryscienti?cdisciplines.

The need to improve communication between humans and computers has been instrumental in de ning new modalities of communication, and new ways of interacting with machines. Gestures can convey information for which other modalities are not e cient or suitable. In natural and user-friendly interaction, gesturescanbeused, asasinglemodality, orcombinedinmultimodalinteraction schemes which involvespeech, or textual media. Speci cation methodologiescan be developed to design advanced interaction processes in order to de ne what kind of gestures are used, which meaning they convey, and what the...
