Linot, Béatrice2018-06-072018-06-072018My Doctoral research aims to identify the psychological and social factors that influence trust and determine the information sharing behavior of professional participants in the crisis response system. Building on the idea that the computer disrupts these factors, our aim is to design tools that restore the conditions of trust in a framework of collaborative information sharing. I combine theory and methods used in psychology and human factors, with computer science to determine how and why trust is degraded in relation to civil security operations. I propose to (1) identify the multi-level factors influencing trust during collaborative activities supported by computers (e.g., contextual factors, organizational factors, individual factors,); and (2) identify data-based design guidelines for digital devices that promote the sharing of information related to civil security and thereby develop and maintain shared situational awareness during collaborative activities.enText/Conference Paper10.18420/ecscw2018_dc72510-2591
