The Correlation of speech and hand gestures for multimodal web interaction
Jing Liu, Manolya Kavakli · 2013
With the development of Multimodal Interfaces (MMI) in Human Computer Interaction (HCI), there is an increasing interest at applying this technology to multimodal web interaction. Multimodal web interfaces can provide endusers with a natural, flexible and non-invasive interface that allow graphical, vocal and gestural interaction with web. Integration of speech and gestures in an MMI framework is now the focus of the researchers in this area. In order to combine speech and gestures in multimodal web interaction, it is essential to know the correlations between speech and associated gestures. This paper presents an empirical study aimed at studying the correlations between speech and hand gestures from a cognitive aspect. The methodology used in this paper is the video analysis to investigate the cognitive actions of speakers in the descriptions of objects using speech and hand gestures. The speakers' cognitive actions are analyzed using a cognitive scheme and protocol analysis method. Our initial findings suggest that speech is highly correlated with co-verbal hand gestures perceptually and semantically, regardless of the age, gender, background of the speakers, or the speed of speech and gesticulation.
