It has been designed to support both stored and live broadcast/broadband content, in mosaic or warp distributions. The displays and devices can be dynamically configured via web in different ways: the displays can create a single display of a larger size;or they can be configured in a customized way in order to playout different media contents in different display combinations. As display renderers, low-cost devices are proposed as the main hardware element to obtain affordable videowall systems. As a proof of concept, two prototypes have been implemented, including an accurate synchronization mechanism based on a Master/Slave control scheme and aggressive and smooth playout adjustment techniques. To evidence the good performance of the prototypes and configuration service, both objective and subjective evaluations have been conducted regarding synchronization accuracy and usability. On the one hand, the mean values of the asynchronies between the video playout processes in each display are kept below 25ms (i.e., frame accuracy). On the other hand, the obtained usability score in the System Usability Scale (SUS) test has been 88.65, which is considered as excellent.展开更多

Despite the extant conceptualizations of political influence tactics in organizations, very little research has focused on how these tactics play out for organizations implementing more autonomous team settings, whose interactions are not proximally located close to one another. By extending social influence theory to the inclusion of media synchronicity theory, this research contributes insight into how political influence tactics may operate across a variety of media in organizations employing remote work structures. A conceptual model of remote influence tactics is developed and the implications are discussed as part of this research agenda.展开更多
