The studio is divided into five parts, which follow a co-creation design process [11]: Research, Exploration, Ideation, Conceptualization and Prototyping. The participants will go through each part in the role as a user and later analyze the outcomes and learnings of each part.

Before the hands-on part, the participants will be introduced to the PD approach. Some examples of previous work (e.g. [3]) will be shown to give them an overview and understanding of participatory thinking and working in the field of tangible interaction.

We will define the user group (business travelers), the context (business trip) and purpose (enrichment of experience) of the session’s design process. Guided by a timeline the participants will first collaboratively discuss the user journey [9] of business travelers, and highlight situations, events and experiences of particular interest that will lead towards one specific use case.

To explore the use case practically, three participatory hands-on methods will be applied: personal inventory, extreme users and bodystorming. The personal inventory method [8] will raise awareness for the business travelers’ personal belongings and emotional attachment towards them. The participants will define extreme users [2] collaboratively. This will support the investigation of the behavioral patterns business travelers perform during a journey. The bodystorming activity [10] is aligned with an “expressive-movement view“ [13]. In this phase, the participants will act out relevant scenarios and business trip experiences, and analyze expressive body movements on human-(object-) interactions.

The outcomes of the exploration will be the basis for an ideation phase. By collecting and clustering the findings in a card-sorting activity [7], the main results will become visible. We will use pictorial and linguistic comparisons and metaphors [1] in order to prepare the conceptualization phase.

The results of the ideation phase will lead to concepts that explore different ways of enriching a business trip experience. By describing and visualizing the concepts, the participants will create the foundation for the prototyping phase in form of storyboards [6].

Using paper and adhesive tape, the participants will rapidly prototype [4] and co-create [11] the TUI- concepts in groups. Each group will act out scenarios taken from the storyboards that show the main features of the prototypical concepts. By filming these human-TUI-interactions [6], each concept will be recorded as Video-Prototypes. To complete the exemplary design process, the implementation phase would be the next phase, in which prototypes could be developed iteratively including intensive user testing.

After finalizing the TUI prototypes, the participants will reflect on and analyze the studio session by reviewing the applied participatory methods. We will discuss the advantages and disadvantages and share best- practices, so that the participants can easily transfer and apply the methods afterwards in their own tangible interaction projects. By discussing and comparing discoveries of the session, new insights and skills will derive for all parties involved.
