When designing an interactive system, considering usability is important in order to ensure that users can perform their tasks with the interactive system and that each information or function they need to perform their tasks is available at most relevant time. Consideration of the user experience is also important in order to take into account how users feel about using the interactive system. In case where users belong to different user profiles, design of the interactive system may have to consider conflicts between target usability and user experience. From study of the documentation and users’ knowledge, we present a multi-user and multi-property control center: Jupiter 2 Control Center at Guiana Space Center of French space studies center (CNES). As public audience and press are allowed to assist to launch in the Jupiter 2 Control Center, they can see operators’ work and information displayed in the control center. Then, specificity of this control center compared to others is that different user profiles with different goals use it at the same time. Some users use it to perform their work, whereas others use it to enjoy the launch. We use the Jupiter 2 Control Center as an example to find potential design issues for a future control center with similar characteristics. Conflicts between the different users’ goals and the related properties are discussed in this paper.
