Eye tracking data representation and visualization : on information and communication studies at CETAC.MEDIA

Eye tracking has become a preponderant technique in the evaluation of user interaction and behaviour with study objects in defined contexts. Common eye tracking related data representation techniques offer valuable input regarding user interaction and eye gaze behaviour, namely through fixations and saccades measurement. However, these and other techniques may be insufficient for the representation of acquired data in specific studies, namely because of the complexity of the study object being analysed. This paper intends to contribute with a summary of data representation and information visualization techniques used in data analysis within different contexts (advertising, websites, television news and video games). Additionally, several methodological approaches are presented in this paper, which resulted from several studies developed and under development at CETAC.MEDIA - Communication Sciences and Technologies Research Centre. In the studies described, traditional data representation techniques were insufficient. As a result, new approaches were necessary and therefore, new forms of representing data, based on common techniques were developed with the objective of improving communication and information strategies. In each of these studies, a brief summary of the contribution to their respective area will be presented, as well as the data representation techniques used and some of the acquired results.

Flow e os fenómenos de mentoria e liderança em indústrias de injeção de plásticos da Marinha Grande

Este estudo procura investigar possíveis associações entre as experiências de flow e os fenómenos de mentoria e liderança. Procura-se identificar as características e benefícios de experiências de flow e de relações de mentoria e liderança, percebidos pelos colaboradores de quatro empresas de Injeção de Plásticos da Marinha Grande. Identificam-se as funções de mentoria, os estilos de liderança transacional, transformacional e servidora e os componentes de flow entre estes colaboradores. Para a medição dos estilos de liderança foram utilizados os instrumentos desenvolvidos por Avolio e Bass (2004) e Dennis (2004). Para as funções das relações de mentoria, definidas por Ragins e Kram (2007), o instrumento desenvolvido por Noe (1988). Para os componentes observados em experiências de flow, o instrumento desenvolvido por Jackson e Ecklund (2002). Apoiado nos instrumentos referidos foi aplicado um questionário na recolha dos dados para este estudo. Foram encontradas influências moderadas e fortes entre os estilos de liderança, as funções de mentoria e os componentes de uma experiência de flow.
