Head and eye egocentric gesture recognition for human-robot interaction using eyewear cameras [article]

Javier Marina-Miranda, V. Javier Traver
2022 arXiv   pre-print
In particular, we focus on head and eye gestures, and adopt an egocentric (first-person) perspective using eyewear cameras.  ...  We argue that this egocentric view offers a number of conceptual and technical benefits over scene- or robot-centric perspectives.  ...  Network architecture and training For gesture recognition, we propose a motion-based approach which processes image sequences at two temporal levels (Figure 1 ).  ...

Conceptual and lexical effects on gestures: the case of vertical spatial metaphors for time in Chinese

Yan Gu, Lisette Mol, Marieke Hoetjes, Marc Swerts
2017 Language, Cognition and Neuroscience  
Additionally, Chinese English bilinguals prefer vertical gestures to lateral gestures when perceiving Chinese time references with vertical spatial metaphors and the corresponding English translations,  ...  In conclusion, the vertical gesturing about time by Chinese English bilinguals is shaped by both the stable language-specific conceptualisations, and the online changes in linguistic choices.  ...  We thank Yeqiu Zheng for LANGUAGE, COGNITION AND NEUROSCIENCE  ...

Dyadic brain modelling, mirror systems and the ontogenetic ritualization of ape gesture

M. Arbib, V. Ganesh, B. Gasser
2014 Philosophical Transactions of the Royal Society of London. Biological Sciences  
We earlier offered a conceptual model of the brain mechanisms that could support this process, using an example of a child's initial pulling on a mother eventually yielding a 'beckoning' gesture [10] .  ...  However, a few group-specific gestures have been observed in ape populations, suggesting a role for social learning [3] .  ...  gestural space'.  ...

2009 Proceedings of the 7th International Conference on Advances in Mobile Computing and Multimedia - MoMM '09  
We describe our work in the application of three types of successful movement recognition applied in the field of Tai Chi with the objective being to identify gestural primitives of club dance associated  ...  In this approach, dance movements are first recognized and classified and then mapped, using multiple levels of complexity, to higher level algorithms that can modify multimedia content in real time.  ...  If regions are sparsely populated, then fewer codes are used to specify that space.  ...
