This workshop will reach a first step for the Tangible User This research field is becoming even more relevant in the Interfaces (TUI) Characterization. This first step allows us to HCI community during the last years. This relevance makes collect information about TUIs features. Then, future work Tangible User Interfaces (TUIs) present in several will be to use this information to classify TUIs using cladistic application areas. This presence generated a variety of methods. Running cladistic algorithms will be the first interfaces design. Each year, researchers design new attempt to classify TUIs as biologists did with living prototypes again. However, stating the similarities and organisms. This attempt will then help to develop new TUI differences between existing and novel interfaces remains taxonomies thanks to an interactive cladistics online tool. difficult. IMPACT FOR THE HCI COMMUNITY This workshop addresses one question “What are the The characterization of TUIs is important for the HCI characteristics of a Tangible User Interface”. Our workshop community because after this workshop the participants will aims at answering this question in four parts. First, this be capable of: question asks researchers/developers/students/innovators to think about the challenges tackled by the development of a - Easily locate the main characteristics for the TUI and about how do they can describe a TUI? Second, it development of a new TUI, according to the asks the tangible artefacts design a TUI? Third, it asks the objectives of their projects, relevant constraints in the TUI development related to the - Thoroughly analyze the elements of a TUI for using/adapting in new projects and - To decompose a TUI in its essential elements. All these skills developed during the workshop give some benefits to the community as: the researchers can address this question to develop their practical understanding of how to tackle the complexity of developing/using a TUI and researchers can benefit from using a tool to characterize and storage their TUIs. All the community will benefit from the workshop by freely accessing the collected information on the website of the tool. WORKSHOP SCHEDULING The workshop will be articulated in the following phases: • Introduction to the workshop and explanation of the characterization (about 35 minutes) • Recapitulation of tangible interfaces to be characterized (about 15 minutes) • First brainstorming and working in the characterization tool (about 1h30 minutes) • Tangible interface presentations and discussion (about 40 minutes) REFERENCES 1.
