Learned vocal and breathing behavior in an enculturated gorilla

Marcus Perlman, Nathaniel Clark
2015 Animal Cognition  
Each of these behaviors is performed in the context of particular manual action routines and gestures.  ...  Ethical standard All applicable national guidelines for the care and use of animals were followed.  ...  She also sometimes used other gestures like perpendicular hands, bringing her two palms together and her thumbs to her mouth, and overlapping hands, placing one hand on top of the other and bringing her  ...

A Survey on Human Behavior Recognition Using Smartphone-based Ultrasonic Signal

Zhengjie Wang, Yushan Hou, Kangkang Jiang, Chengming Zhang, Wenwen Dou, Zehua Huang, Yinjing Guo
2019 IEEE Access  
Afterward, according to the purpose of these applications, we classify them into five groups and compare them in detail including hand gesture recognition, activity recognition, hand trajectory tracking  ...  In this paper, we first review the common behavior recognition techniques including light, video, sound, and frequency radio and outline their main characteristics.  ...  We consider two types of acoustic signals: audible sound and ultrasound. The former can be used to sense environment sound, extract sound features, and identify human actions.  ...

Vocalizations are classified and interpreted as instances of sound models, which the user can play with by vocal and gestural control.  ...  Sound models can be selected by vocal imitations that are automatically classified, and each model is mapped to vocal and gestural features for real-time control.  ...  using manual gestures.  ...

Use of gesture sequences in captive chimpanzee (Pan troglodytes) play

Maureen S. McCarthy, Mary Lee Abshire Jensvold, Deborah H. Fouts
2012 Animal Cognition  
They rarely used visual gestures toward inattentive recipients. Auditory/tactile gestures were effective with and used with both attentive and inattentive recipients.  ...  We hypothesized that chimpanzees would use visual gestures toward attentive recipients and auditory/tactile gestures toward inattentive recipients.  ...  For assistance with video archive use, we thank Jason Wallin. We also thank Stephen Lea, Catherine Hobaiter, and one anonymous reviewer for helpful comments on an earlier draft of our manuscript.  ...

Arabic Sign Language Recognition an Image-Based Approach

M. Mohandes, S.I. Quadri, M. Deriche
2007 21st International Conference on Advanced Information Networking and Applications Workshops (AINAW'07)  
Third process is the hand gesture recognition.  ...  In this proposed system, a well trained computer system is used to recognize static hand gestures representing linguistic words.  ...  Sign Language is a non verbal method of communication in which gestures are made using hands.  ...

Sonic Gestures As Input In Human-Computer Interaction: Towards A Systematic Approach

Antti Jylhä
2011 Proceedings of the SMC Conferences  
For example hand claps, finger snaps, whistling, all vocal sounds, and body tap sounds can be considered emptyhanded gestures, even if hands can be used in their production.  ...  For example, it has been shown that different hand configurations in clapping result in audibly different sounds and that it is possible by machine learning techniques to also differentiate between these  ...

Augmenting touch interaction through acoustic sensing

Pedro Lopes, Ricardo Jota, Joaquim A. Jorge
2011 Proceedings of the ACM International Conference on Interactive Tabletops and Surfaces - ITS '11  
Our contribution is the integration of touch and sound to expand the input language of surface interaction.  ...  IMPLEMENTATION DETAILS Acoustic cues require the use of microphones to capture the sound signature of gestures.  ...  This evidence supports our vision to provide a richer input language, by augmenting gesture classification with impact intensity and timbre plus location and shape.  ...

Speech through the Ear, the Eye, the Mouth and the Hand [chapter]

Marion Dohen
2009 Lecture Notes in Computer Science  
It then analyses some aspects of hand-mouth coordination in spoken communication.  ...  This study also confirms that the coordination is rather between the hand and the articulatory gestures than between the hand and the sound.  ...  On the other hand, theories of gestural origins of language argue that the hand was used for communication before the mouth.  ...
