A review on development approaches for 3D gestural embodied human-computer interaction systems

The integration of 3D gestural embodied human-computer interaction (eHCI) has provided an avenue for contactless interaction with systems. The design of gestural systems employs two approaches: Technology-based approach and Human-based approach. This study reviews the existing literature on development approaches for 3D gestural eHCI to understand the current state of research in 3D gestural eHCI using these approaches and identify potential areas for future exploration. Articles were gathered from three databases: PsycInfo, Science Direct and IEEE Xplore. A total of 35 articles were identified, of which 18 used human-based methods, and 17 used technology-based methods. Findings shed light on inconsistencies between developers and users in preferred hand gesture poses and identify factors influencing users’ gesture choice. Implementation of the consolidated findings has the potential to improve human readiness for 3D gestural eHCI technologies.
