Gesture Production

Does gesturing primarily serve speaker internal purposes, or does it mostly facilitate communication, for example by conveying semantic content, or easing social interaction? To address this question, we asked native speakers of Dutch to retell an animated cartoon to a presumed audiovisual summarizer, a presumed addressee in another room (through web cam), or an addressee in the same room, who could either see them and be seen by them or not.
We found that participants produced the least number of gestures when talking to the presumed summarizer. In addition, they produced a smaller proportion of large gestures and almost no pointing gestures. Two perception experiments revealed that observers are sensitive to this difference in gesturing. We conclude that gesture production is not a fully automated speech facilitation process, and that it can convey information about the communicative setting a speaker is in.

Pointing Gestures

Gestures played a role in the learning of mathematics, especially in the Sliced Cone and Polar Coordinates material. Educators gestures associated with conceptual planning of the explanations and is the embodiment of knowledge and understanding of educators associated with the material being studied. The educators’ gestures were pointing gestures, representations and writing. Gestures appeared at the planning stage, especially the activities of peer teaching and learning implementation. Both of two steps related to the implementation of lesson study in math learning. Gestures accompanied explanations educators help to clarify, explain, and emphasize mathematical concepts in the material being studied.

Problem Solving Task

Successful collaboration often relies on individuals' capacity to communicate with each other. Despite extensive research on chimpanzee communication, there is little evidence that chimpanzees are capable, without extensive human training, of regulating collaborative activities via communication. This study investigated whether pairs of chimpanzees were capable of communicating to ensure coordination during collaborative problem-solving. The chimpanzee pairs needed two tools to extract fruits from an apparatus. The communicator in each pair could see the location of the tools (hidden in one of two boxes), whereas only the recipient could open the boxes. The subjects were first successfully tested for their capacity to understand the pointing gestures of a human who indicated the location of the tools. In a subsequent conspecifics test, the communicator increasingly communicated the tools’ location, by approaching the baited box and giving the key needed to open it to the recipients. The recipient used these signals and obtained the tools, transferring one of the tools to the communicator so that the pair could collaborate in obtaining the fruits. The study suggests that chimpanzees have the necessary socio-cognitive skills to naturally develop a simple communicative strategy to ensure coordination in a collaborative task.

Human Pointing

The detailed and profound understanding of the temporal and spatial organisation of human pointing actions is key to enable developers to build applications that successfully incorporate multimodal human computer interaction. Rather than discussing an ideal detection method for manual pointing we will discuss crucial aspects of pointing actions in time and space to develop the right solution for a particular application. One core element of pointing in the temporal domain is the so called dwell-time, the time span that people remain nearly motionless during pointing at objects to express their intention. We also discuss important findings about the spatial characteristics of the target representation for the pointing gesture.The findings foster better understanding of the role of pointing gestures in combination with other modalities and inform developer with substantial knowledge about the temporal-spatial organisation of the pointing gesture.
