CORTES-RICO, Laura  e  PIEDRAHITA-SOLORZANO, Giovanny. Gestural Based Interactions: Critical Review. TecnoL. [online]. 2019, vol.22, n.spe, pp.117-130. ISSN 0123-7799.  https://doi.org/10.22430/22565337.1512.

This paper presents a critical review of human-computer interactions (hci) based on gestures. Gestures, as ways of non-verbal communication, have been of interest in hci because they make possible the interaction with the machine through the body, as an agent that perceives and acts in the world. The review was carried out in the most critical databases in hci, as well as some Latin-American academic sources, and included an analysis of the evolution of gesture-based interactions, current work, and future perspectives. The article is carried out holistically, considering both technical and human issues: psychological, social, and cultural, as well as their relationships. We present this analytical process as a scientometric description of the search results, the description of the gesture as a means of interaction, the techniques used for the different steps in the gesture recognition process, and the presentation of the applications and challenges of gesture-based interactions. It concludes through a series of questions that invite the reader to think about potential research focus on gesture-based interactions.

Palavras-chave : Gestures; human-computer interaction; gesture recognition; gesture based interactions.
