The interactive device provides information in different formats and assessment and consolidation activities that enable teachers to obtain greater benefit from school visits, with preparatory work or consolidation after the visit to be done in the classroom. That broadens the interpretation of the museum and gives more meaning to the learning process contextualised on the visit. There is no doubt that the availability of multimedia material that can be consulted on line, with abundant graphic elements and detailed descriptions, is of enormous assistance in analysing the objects, machines and processes to be found in the museum.

The characteristic of these multimedia materials is the transversal treatment of technological, social and environmental aspects from a historical point of view, with keys for interpreting the present state of the textile sector. This integrated view helps discover links between the scientific, technological and social aspects that are inevitably involved in any technological process.

The incorporation of multimedia resources boosts knowledge and analysis of the contents, especially the more complex ones that require a description and visual presentation and a chain of actions. That is particularly important at a time when the educational system is proposing a mass introduction of computers into the classroom and high capacity connections at educational centres. 

The contents of the material have been structured in five interlinked blocks:

- The social context.
- The textile process.
- Energy.
- Machines.
- Mechanisms.

Each of the sections and the various subsections contains textual descriptions and images, and in some cases digital videos and multimedia animations have been added.

The social context deals first of all with the industrial situation at the end of the 19th century and the beginning of the 20th in Catalonia and then turns to the  Aymerich Amat i Jover mill in the city of Terrassa.

Steam energy and its transformation into movement is shown in detail in this section.

The textile process focuses on wool, the fibre that was worked at the Aymerich mill. A special subsection is set aside for the state of the textile sector today and how the globalisation process is affecting it. Another subsection deals with the generic impact of the textile industry on the environment.

The machines section has documented the most important ones in the exhibition. Those that are still functioning have been recorded on video and a multimedia animation has been produced to provide a visual demonstration of their operation.

The mechanisms section supplies the data for the operation of the basic mechanisms of the textile machines on show.

This material is the second of the Multimedia resources for teaching technology, which has been produced in association with various organisms and institutions: the Science Education Institute at the Polytechnic University of Catalonia, the Catalan Technology Teachers Association and the Catalan Government (Generalitat de Catalunya) Departments of Education, and Culture and the Communications Media. This is a valuable asset which guarantees quality materials adapted to the needs of the secondary school classroom and ensures that this tool is familiar to the teaching community and future teachers who are still training.
