Abstract. People with special needs may find difficulties using electronic consumer devices, user interfaces limit their chances of having full control on them. The Universal Remote Control (URC) is an ISO standard that promotes pluggable and interoperable user interfaces to remotely operate electronic devices. The Universal Control Hub (UCH) is the software architecture that materialises URC, and several implementations are currently available. However, users and developers wonder about UCH feasibility to respond to future needs regarding performance. In this paper, we conduct a study to analyze whether UCH can face multiple concurrent users. Serious problems are exposed at this regard in this paper, they may contribute to question a solution that initially and from the interoperability point of view was very-well suited.
