Cooperative work conditions in a satellite control room. Emma Alvarez Conservatoire National des Arts et Métiers 41 rue Gay-Lussac, 75005 Paris, France Summary and presentation The general question posed was: Do environmental resources have an impact on acquisition of knowledge and on the construction of a collective memory? The context is a satellite control room,where three controllers work on shift. They have similar competencies and there is no division of labour. In this particular environment, it seems to be the case that visual and hearing access to everybody's activities make coordination possible. This access is due to the open tools and the open environment. Two interesting concepts were introduced (both taken from Hutchins, 1990): the horizon of activities, by which is meant each person's outer boundary of the portion of the task that can be seen or heard. This changes according to the workload on the operator. the trajectory of information, by which is meant information which is "broadcasted", without any particular intention to be processed. This broadcasting enables the access to others' activities, when there is time and seems to be need for intervention.
