  1. Towards a definition of GestBase- an open database of gestures Milan Rusko Institute of Informatics of the Slovak Academy of Sciences, Bratislava

  2. Motivation Publishing studies on gestures face_and_body gestures voice gestures Video – often not included in the electronic publication, no widely accepted form of annotation suitable for basic comparisons etc. Photos – occupy too much space in the printed publication , no standard or widely accepted annotation suitable for basic comparisons Audio – not available in the printed publications =>replaced by ambiguous orthographic code (mhm, oooh, etc. ) Text (periphrastic) description – ambiguous, insufficient, no standard form All suffer from lack of comprehensive method of referencing. It is hard for the reader to imagine the gesture. COST 2102 DUBLIN 2009

  3. Vision of solution - GestBase Possible solution - an open database of Gestures Such a database should • have standardized format of entries • allow for storage of gestures in multiple modalities and their annotations • allow for storage of gestures in context • allow for search, comparison, and other database operations • be accessible for all potential users • be open for new submissions

  4. Database structure Visual gestures database pictures (photos) textual description of the gesture coded description of the picture ... Semantic & Pragmatic content (meaning) Comments Nonverbal speech gestures database sounds (recordings) orthoepic (IPA) transcription orthographic (text) trsc. Automatically derived acoustical chars (F0 contour, ...) Coded acoustical char. Para and Extra-linguistic Semantic & Pragmatic content Function in the dialogue Comments

  5. Pilot study: first submisson – GestBase_Sk ver0.1 Procedure in ver0.1: Standard procedure:

  6. Collection of stimuli induced gestures • The speaker gets a stimulus – a gesture represented in one modality, and he has to add other modalities and additional information. • stimulus=photo, speaker ads sound (or several sounds), context (creates a sentence) his own description of the meaning and typical usage.(initial set of photos taken from Ruzickova) • stimulus=text (orthographic form of the gesture etc.) speaker adds sound (in future we plan also video recording) • (list of interjections and particles taken from Slovak National Corpus) • 3. stimulus=sound (nonverbal speech gesture, possibly in context)

  7. Ideas on usability of GestBase Possible usage of GestBase could be a photo-sound-text electronic upgraded version of Ružičková: American, Slovak, Japanese and Chinese Picture dictionary of Gestures. (possibly extended with other languages) This is a publication which is aimed at giving information to the foreign language learners on the gestures in the given language and their comparison with the ones in his mother tongue. Inter-lingual and inter-cultural comparison studies: Slovak – Hungarian (one culture, very different languages) Slovak – Japanese (very different cultures) etc.
