This research is processed by a framework of multimodal data analysis, based on the indications by Bezemer & Kress (2016), Machin (2016), Jewitt et. al., 2016, Kress (2010) and Norris (2004). Multimodality considers communication as a complex multi-layered system of symbols that is underpinned by the following three assumptions: a) communication is always multimodal; b) the modes are cultivated by community; c) the communication modes are selected according to the task. 'Modal affordance and constraints' describe the characteristics of a mode that determine its uses.
