Abstract :
In this thesis, I study the benefits of collaboration using an Ultra-High Resolution Interactive Wall Display (UHRWD). I focus on the specific collaborative context of control rooms. Visits of control rooms and interviews with operators show that different degrees of collaboration are required in function of the situation. I believe that a UHRIWD could be beneficial in situations when close collaboration is needed. I first show that wall display encourages close collaboration compared to multiple separate displays. Then I show that the interaction techniques can also influence the degree of collaboration, for instance, a technique with a large visual footprint also encourages a close collaboration. I apply this in the design of technique to visualize road traffic forecast on a wall display for road traffic control centres. Finally, I propose techniques to help the transition between the different setups of a control room: the workstations and the wall display.

DECODING THE PLATFORM SOCIETY: ORGANIZATIONS, MARKETS AND NETWORKS IN THE DIGITAL ECONOMY
The original manuscript conceptualizes the recent rise of digital platforms along three main dimensions: their nature of coordination devices fueled by data, the ensuing transformations of labor, and the accompanying promises of societal innovation. The overall ambition is to unpack the coordination role of the platform and where it stands in the horizon of the classical firm – market duality. It is also to precisely understand how it uses data to do so, where it drives labor, and how it accommodates socially innovative projects. I extend this analysis to show continuity between today’s society dominated by platforms and the “organizational society”, claiming that platforms are organized structures that distribute resources, produce asymmetries of wealth and power, and push social innovation to the periphery of the system. I discuss the policy implications of these tendencies and propose avenues for follow-up research.
