Workshop Entrain, Exploring New Territorial User Interfaces

Entrain, Exploring New Territorial User Interfaces


The Entrain workshop focus on modeling and specification of collaborative systems where users interact through multi-surface devices.
We aim at exploring the different approaches to design interactive applications for groups of users using a set of interacting surfaces to perform their tasks with an optimal user experience. Participants are invited to present both the models and/or design methods as well as the case studies and applications they are studying in this context. We would like to set up a discussion group in order to put each person’s work in perspective with the notion of territoriality applied to ambient computing and multiple devices. The territoriality theory may serve as a basis for the design of complex interactive applications of quality. From these discussions will emerge a mapping of models and design methods that could be mutualized and combined.

Territoriality Theory


Territoriality concepts have been proposed by the Scott and Carpendale’s Theory about Tabletop Territoriality (Scott 2010). The theory was elaborated from a study of collaborative practices of workspace partitioning on traditional (physical) tabletops in order to design digital tabletops. Indeed, Scott and Carpendale anticipated to use it later on to design tabletops connected to mobile devices such as tablets and smartphones: “Digitizing the workspace also enables workspace configuration possibilities such as multi-display systems that provide a shared tabletop workspace connected to multiple mobile personal workspaces displayed on tablet or smartphone devices” (Scott 2010).

Examples of territories


Due to Covid-19 pandemic situation, the EICS 2020 Conference is canceled. So we reschedule the Workshop Organisation.

11:05-12:30 : talks  14:00-14:55 :  talks
15:00-16:30 : discussions
The discussion will focus on the identification of the contributions of territoriality, its uses and definition(s),  the related/related concepts. We will structure all the identified notions.

Workshop Contributions

These two sessions are aimed towards gathering participants who are concerned by Models and Design Methods for Multi Surfaces User Interfaces especially excited about the opportunity to gather experiences around the territoriality notion.
Participants will be invited to submit an abstract on topics such as: the use of the concept of territoriality in the context of a distributed or non-distributed interactive application, the use of model definition in interactive applications for a group of users interacting with a set of interactive surfaces to perform their tasks, the use or definition of development methods, rules, guidelines for interfaces on multi-surfaces, case studies to illustrate the problem and proposals for solutions in areas such as games, collaborative design, trips in public places.

Important Dates and Workshop Selection

A the remote session in June, submit your positioning on the online form:https://bit.ly/nomos-2020-06-23
This remote meeting is free of charge, but all participants should fill the form, even without positionning.
Deadline: June, the 19th 2020


For the remote session in November, the workshop will begin with flash presentations. We will provide a consistent format for the presentations. We will discuss in sub-groups to put the work and the notion of territoriality into perspective. We will meet to synthesize the results of the groups as a mapping of each proposed models or approaches. We will establish a future research agenda.
Deadline (Participation): November, the 6th 2020 : http://bit.ly/nomos-2020-11-participation
Inscription Deadline (no fee): November, the 23th 2020 : http://bit.ly/nomos-2020-11-attendance


Future directions

The key outcomes of the workshop will be shared online, as a blog post on the workshop webpage. In addition, we also plan to organize a follow-up workshop in 2021 with a similar theme. This is aimed towards not only ensuring continual exchange and collaboration among the participants, but also to attract other members of the wider HCI community who might not be present at EICS.
A "white paper" synthesizing the results of the workshop can be considered if it is conclusive. In the longer term, a book in the HCI series could be considered, once sufficient contributions have been received.

Presentation of the organizers

The organizers of this Workshop are partners of the NOMOS project supported by the Hubert Curien Partnership Tournesol program which facilitates scientific cooperation between France and Belgium: Prof. M. Winckler, AM Dery Pinna and P. Renevier Gonin assistant professors in the I3S laboratory; S. Lepreux assistant professor and C. Kolski professor in the LAMIH laboratory UMR CNRS 8201, UPHF; J. Vanderdonckt professor in Université Catholique de Louvain (UCLouvain).

In ancient Greek, Nomos (óμo, “law” or “custom”) derives its etymology from the verb ´μ(to dispense or to allot), with Nomos being the result of allotment or the manner of allotment or dispensing. We used this metaphor to express the concept of territorial user interface, a novel type of a distributed user interface that is regulated not by the physical principles of platforms or the implementation constraints imposed by widgets, but by the interpersonal space end users have among themselves.

The I3S team is basing part of its work on the composition of IU on model engineering [3–5]. The publications [9] and [1] attest to the knowledge of LAMIH in terms of tangible interaction and multi-surface interfaces. The I3S and LAMIH laboratories explore the notion of territory in the design of distributed interfaces [5].

Jean Vanderdonckt is full professor in information systems leading the Louvain Interaction Lab, Université Catholique de Louvain, Belgium. His research focuses on the contextual adaptation of user interfaces [13] and intelligent techniques to support the adaptation of user interfaces at the time of design and/or execution [2]. He is a past president of the ACM IUI ’04 conference and is co-chair of the ACM EICS ’20 Full Papers conference.
