Developing visual tools that support data analysis in a specific application domain requires a careful investigation in order to understand needs and expectations of people who will use such tools. The domain experts addressed in this paper are chemists specialized in environmental data analysis. Their main activity is to detect and monitor chemical compounds in the air through many devices in order to detect anomalies or prevent risks. One of the main problems that chemists face is the analysis of the huge amount of data produced by devices. They perform explorative data analysis and are willing to use software tools that can help them to get insights from data. This paper reports the experience in working with chemists to identify interactive visual tools that can be useful for their purposes. It provides insights on the difficulty of creating systems that users find really useful for their work, even when users participate in the design team. Because of the complexity of the considered problem and the fact that people are unable to make explicit all their needs and requirements, the identification of proper tools resulted very challenging.

Abstract
Developing visual tools that support data analysis in a specific application domain requires a careful investigation in order to understand needs and expectations of people who will use such tools. The domain experts addressed in this paper are chemists specialized in environmental data analysis. Their main activity is to detect and monitor chemical compounds in the air through many devices in order to detect anomalies or prevent risks. One of the main problems that chemists face is the analysis of the huge amount of data produced by devices. They perform explorative data analysis and are willing to use software tools that can help them to get insights from data. This paper reports the experience in working with chemists to identify interactive visual tools that can be useful for their purposes. It provides insights on the difficulty of creating systems that users find really useful for their work, even when users participate in the design team. Because of the complexity of the considered problem and the fact that people are unable to make explicit all their needs and requirements, the identification of proper tools resulted very challenging.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
