Tangible interactions in control centres for railway traffic management

International audience; A current trend in rail industry control centres is to move towards an increase in the number of digitaltools to assist operators. Our observations show that the information used by rail controllers is distributedamong different interfaces. Operators must assemble all this information themselves to understand thestate of the system. This task is often done mentally, resulting in difficult information sharing and aslower decision process. It is in this search for improvement of the operational centres that we realizeda prototype of a tangible touch table presented in this article. The first tests are underway and allowus to have rather positive feedback on this technology that operators are not familiar with. The nextiterations will focus on refining the prototype and on experimenting with a larger group of users.
