Pointing Gesture

Summary Lev Vygotsky’s (1896–1934) views of the genesis of language and its relation to thought, illustrated here by his account of the origin of the pointing gesture, can be seen as anticipating current research in socially constituted cognition, pragmatics, developmental psychology and grammaticalization, in all of which the importance of contextual and pragmatic factors looms large. His conceptualization of the evolution of communication from action to semiosis has bearing on, and is illuminated by, recent developments in neurobiology, developmental psychology, primatology, and grammaticalization theory. Specifically, recently discovered mirror neuron systems may offer a neurophysiological platform for the evolution of language from gesture and imitation, for the transition from action to sign, from referential to relational meaning, an evolution in which the establishment of joint attention is pivotal. With his emphasis on the dynamic, socially constructed nature of signs, Vygotsky shares Humboldt’s view of language as energeia, as a system in a perpetual state of emergence, a view consistent with Condillac’s ‘language of action’, in which spontaneous vocalizations and gestures give rise to sign functions. Research of the grammaticalization pathways associated with demonstratives and modal particles also offers new perspectives on the process and hypothesized unidirectionality of grammaticalization, including the plausible claim that demonstratives represent a second and separate source of candidates for grammaticalization. Integrating grammaticalization research with findings from relevant social and natural sciences holds out the prospect of underwriting significant advances in understanding the origin of language and the emergence of grammar.

Abstract We examine gestural development, and correlations between gesture types, vocalizations and vocabulary at ages 8 to 15 months, employing data from MacArthur-Bates Communicative Development Inventories for Peruvian Spanish, in the first such study with Peruvian children. Results show (1) significant change with age in the production of gesture types, with older children producing more; (2) important correlations between gesture types, and both vocalization types and vocabulary after controlling for age effects; and (3) correlations between the trajectory of the pointing gesture in its two modalities (whole-hand and index-finger) with age, vocalizations, and vocabulary, an effect that persists with respect to vocalizations after controlling for age. Our findings, based on a sample from a non-weird population, support a key role for gesture production in early communicative and linguistic development.

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.
