IFIP WG 13.2 + 13.5 Workshop on Dealing with Conflicting User Interface Properties in User-Centered Development Processes
Overview
Whilst usability, accessibility and, more recently, user experience have been prominent in the HCI research other properties such as privacy, trust, security, and reliability (among others) might also affect the development process of interactive systems. In some cases, a property might complement or enlarge the scope of another. For example, whilst accessibility addresses the needs of impaired users to accomplish their tasks with the system, UX goes beyond the pragmatic aspect of usability by taking into account dimensions such as emotion, aesthetics or visual appearance, identification, stimulation, meaning/value or even fun, enjoyment, pleasure or flow state experience. In some situations, a property might be tributary to another one such is the case of reliability and usability when non reliability of interactive software can jeopardize usability evaluation by showing unexpected or undesired behaviors. Moreover, there are some evidence that properties can trade off against each other as it is the case of usability and security. For example, requiring users to change their passwords periodically may improve security but reduce usability as it represents a burden for users to frequently create and remember passwords. As a consequence, users might be keen to workarounds, such as when users take hard notes of hard-to-remember passwords.
Conflicting user interface properties often appear in recommendations for user interface design. The resolution of conflicts between user interface properties is a daunting and demanding task that might require taking into account the trade-offs associated with alternative design choices. It is interesting to notice that when the conflict between properties is understood, the effects of conflicts can be mitigated/reduced by appropriate design.
Examples of conflict resolution between usability, privacy and security can be found at the SOUPS (https://cups.cs.cmu.edu/soups/) community. In this workshop we aimed at enlarge the scope of the research and promote the study of the interplay of multiple user interface properties in a user-centered design process.
Our aim is to cover a large set of user interface properties and try to reveal their inner dependencies. We are also interested in understand how different stakeholders value user interface properties. In a long run, this workshop aims at helping the development of theories, methods, tools and approaches for dealing with multiple properties that should be taken into account when developing interactive system.
Target audience
We invite participants to present position papers describing real-life case studies that illustrate the tradeoffs between two or more user interface properties. Any property related to user interface design is welcome but two or more properties should be addressed in the same contribution. We are also interested in methods, theories and tools for managing multiple user interface properties. Position papers will be published in adjunct conference proceedings of INTERACT 2017.
During the workshop we also expect to discuss how to disseminate individual contributions to the community in the form of a special issue in a HCI journal.
Structure
The morning session will be dedicated to welcoming participants and presenting case studies. Participants will be invited to comment the case studies and to report similar experiences.
The afternoon sessions will be devoted to interactive sessions, where participants will be invited to work in small groups on and propose solutions to the problems of the case studies presented in the morning.
Solutions proposed by the participants will be compiled and compared. Based on the lessons learned, participants will be invited to draft an agenda of future work that can be accomplished.

Format of submissions
Position paper (6-10 pages in LNCS format) must report practical experiences related to research results on user experience (UX) and user-centered development processes for interactive systems. Authors should also provide in their submission a short summary of their experience in the field and their motivation to participate in this workshop. Submissions will be processed via the workshop web pages that will be hosted at the IFIP WG 13.2 web site. Position papers will be reviewed by the organizers, and participants will be invited to attend the workshop based on review results. All selected contributions will appear in the workshop proceedings as part of the official ad-junct conference proceedings of INTERACT 2017. After the workshop, selected papers will be considered to a post-conference publication in the SPRINGER LNCS series. For that, we will invite authors revise their work according to the comments received during the workshop and prepare a full paper that should be published by November 2017 (tentative).
Submission don’t need to be anonymous. Contributions can be sent by email to ws14-interact2017-organizers@googlegroups.com. If you have any question don’t hesitate to contact the organizers.
