### Summary

The students are introduced to the concept of Multi-display environments (MDE), i.e., the coupling of several displays together to form a shared interactive environment. The concept is described through a taxonomy categorising MDE:s and illustrative examples. The concept of MDE is dwelled into further through the concrete case 4in1 activities, where four tablets are combined to form one large display.

### Learning Outcomes

On completing this module the students should be able to:

- recognize multi-display environments (MDE:s)
- describe relevant factors influencing the design of MDE:s
- analyse the design of MDE:s.
- reflect on the potential consequences of MDE:s for collaborative interaction.
- recognize Topology, Coupling and Interaction as aspects for design of collaborative technology in MDE:s
- analyze Topology, Coupling and Interaction as aspects for design of collaborative technology in MDE contexts.
- reflect on Topology, Coupling and Interaction as aspects for design of MDE:s and the framework’s potential as a tool for ideation.

### Teacher Guidance

This education patterns consists of two main components, a lecture and an accompanying exercise. The expected length of the lecture is 30-45 minutes. The exercise can be given varying amount of time, but a couple of hours is recommended giving a total duration of about 3 hours.

The lecture starts by situating Multi-display environments in the context of Ubiquitous computing and the visions for the Computer for the 21st century by Mark Weiser from 1991. It then proceeds to give a formal definition of the concept Multi-Display Environment and some examples. This is followed by the presentation of a taxonomy for MDE:s that is focused on three main perspectives: topology, coupling and interaction. To make things more concrete the lecture then proceeds with the presentation of one specific MDE called 4in1 activities based on the coupling of 4 tablets to form a shared display.

In the exercise the students practice thinking about MDE:s in terms of the presented taxonomy. They do this by 1) trying to come up with what a MDE version of some application could look like 2) describing the solution invented in step 1 in terms of the presented taxonomy for MDE:s. The exercise is preferably carried out in groups but can be done individually as well.
