Universal Hand Gesture Interaction Vocabulary for Cross-Cultural Users: Challenges and Approaches

This paper highlights the complexity of creating a universal, cross-cultural Hand Gesture Recognition (HGR) vocabulary for global products and systems where worldwide users interact by sharing the same system or space. We revisit the concept of an idealistic universal HGR vocabulary for cross-cultural users and systems that suit all users and present potential development challenges by reviewing the hand gesture taxonomy, lexical, vocabulary, and the current design methods. The analysis emphasizes the importance of creating a cohesive movement towards standardizing HGR vocabulary for innovative products and services that accommodate cultural diversity and converge for a universal agreement at some point.
