Recognizing Micro-Actions and Reactions from Paired Egocentric Videos

Ryo Yonetani, Kris M. Kitani, Yoichi Sato
2016 2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)  
We show that the first-person and second-person points-of-view features of two people, enabled by paired egocentric videos, are complementary and essential for reliably recognizing micro-actions and reactions  ...  To recognize micro-level actions and reactions, such as slight shifts in attention, subtle nodding, or small hand actions, where only subtle body motion is apparent, we propose to use paired egocentric  ...  Acknowledgments This research was supported by CREST, JST and Kayamori Foundation of Informational Science Advancement.  ...

Enhancing Egocentric 3D Pose Estimation with Third Person Views [article]

Ameya Dhamanaskar, Mariella Dimiccoli, Enric Corona, Albert Pumarola, Francesc Moreno-Noguer
2022 arXiv   pre-print
To learn such embedding space we introduce First2Third-Pose, a new paired synchronized dataset of nearly 2,000 videos depicting human activities captured from both first- and third-view perspectives.  ...  Experimental results demonstrate that the joint multi-view embedded space learned with our dataset is useful to extract discriminatory features from arbitrary single-view egocentric videos, without needing  ...  A combination of first-person views from two social partners has been explored for recognizing micro-actions and reactions during social interactions [38] as well as to improve activity recognition of  ...

You2Me: Inferring Body Pose in Egocentric Video via First and Second Person Interactions

Evonne Ng, Donglai Xiang, Hanbyul Joo, Kristen Grauman
2020 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)  
We propose a learningbased approach to estimate the camera wearer's 3D body pose from egocentric video sequences.  ...  We demonstrate our idea on a variety of domains with dyadic interaction and show the substantial impact on egocentric body pose estimation, which improves the state of the art.  ...  UT Austin is supported in part by ONR PECASE and NSF IIS-1514118.  ...

A Mutual Motion Capture System for Face-to-face Collaboration [article]

Atsuyuki Nakamura, Kiyoshi Kiyokawa, Photchara Ratsamee, Tomohiro Mashita, Yuki Uranishi, Haruo Takemura
2017 International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments  
A prototype system has been implemented to evaluate the effectiveness of the proposed method and motion capture accuracy has been compared with two conditions, with and without depth information correction  ...  Moreover, motion capture targeting multiple people is becoming necessary in multi-user virtual reality (VR) and augmented reality (AR) environments.  ...  [YKS16] can recognize micro-actions and reactions from a Table 1 : 1 Motion sequence.  ...

Connecting photosynthesis and cellular respiration: Preservice teachers' conceptions

Mary H. Brown, Reneè S. Schwartz
2009 Journal of Research in Science Teaching  
Understanding connections among biological systems at macro and micro levels is important to biological literacy.  ...  Participants' views were laden with sociological and egocentric components. They often compared plant functions with analogous human functions.  ...  The student failed to see the need for plant cellular respiration, not recognizing that both photosynthesis and cellular respiration are energy reactions within a biological system.  ...

Ten Questions for a Theory of Vision

Marco Gori
2022 Frontiers in Computer Science  
By and large, the remarkable progress in visual object recognition in the last few years has been fueled by the availability of huge amounts of labelled data paired with powerful, bespoke computational  ...  in the control of object-directed action.  ...  It is worth mentioning that motion invariance is not alway desirable since perception and action also need to develop features that provide different reactions in front of motion.  ...

Motor resonance meets motor performance

Guido Barchiesi, Luigi Cattaneo
2015 Neuropsychologia  
The early definitions describe -action understanding‖ as either: a) -…the capacity to recognize that an individual is performing an action, to differentiate that action from others analogous to it, and  ...  increased their firing rate, but the spiking did not change from baseline when the action was performed in an egocentric perspective.  ...

2013 Text & Talk  
Based on a corpus of 40 vlogs, this research categorizes different kinds of common pointing actions in vlogs.  ...  Close analysis reveals the role multimodal factors such as gaze and body posture play along with deictic gestures and verbal reference in the production of a viewer-directed monologue.  ...  While this study is methodologically set to work from a micro-analytic context-sensitive (e.g.  ...

Designing for Kinesthetic Awareness

Jules Françoise, Yves Candau, Sarah Fdili Alaoui, Thecla Schiphorst
2017 Proceedings of the 2017 CHI Conference on Human Factors in Computing Systems - CHI '17  
We designed an interactive sound installation that supports kinesthetic awareness of a participant's micro-movements.  ...  The installation uses field recordings as rich source materials to generate a sound environment that attunes to a participant's micro-movements.  ...  We thank all the study participants for their involvement and feedback, and we acknowledge all the members of the movingstories consortium for fruitful discussions.  ...
