This thesis describes an evaluation of the Hummingbird, which is a support for mobile group awareness. This evaluation was performed at Monter Service, a department at the Swedish Exhibition and Congress Centre in Gothenburg. We used ethnography to build an understanding for the situation and to make a clear picture of what the group thought of the device. Our observations were concentrated to the three areas: awareness, communication and coordination. The findings of the study resulted in some suggestions for improvements of the Hummingbird, it did not support the group to the extent that were intended by the developers. We also used the results to formulate how the group would like such a support to be constituted to fit into their situation.
