Interplay between User Experience Evaluation and System Development (I-UxSED 2012)
IC0904 TwinTide 2nd Open Workshop*

Date: 14th October 2012 (Sunday)
Venue: IT University of Copenhagen, Denmark (in conjunction with NordiCHI 2012)
Deadline for submission: *17th August 2012*

While the gap between HCI and Software Engineering (SE) with regard to usability has somewhat been narrowed, it may be widened again due to the new emphasis on user experience (UX). The main goal of I-UxSED 2012 is to bring together people from HCI and SE to identify challenges and plausible resolutions to optimize the impact of UX evaluation feedback on software development.

Usability evaluation methods (UEMs) and metrics are relatively more mature. In contrast, UX evaluation methods (UXEMs) which draw largely on UEMs are still taking shape. It is conceivable that feeding outcomes of UX evaluation back to the software development cycle to instigate the required changes can even be more challenging than doing so for usability evaluation (UE). It leads to several key issues:

* UX attributes are (much) more fuzzy and malleable, what kinds of diagnostic information and improvement suggestion can be drawn from evaluation data. How does the evaluation feedback enable designers/developers to fix this experiential problem (cf. usability problem) and how can they know that their fix works (i.e. downstream utility)? * Emphasis is put on conducting UE in the early phases of a development lifecycle with the use of low fidelity prototypes. However, is this principle applicable to UX evaluation? Is it feasible to capture authentic experiential responses with a low-fidelity prototype? If yes, how can we draw insights from these responses? * The persuasiveness of empirical feedback determines its worth. Is UX evaluation feedback less persuasive than usability feedback? If yes, will the impact of UX evaluation be weaker than UE? * The Software Engineering (SE) community has recognized the importance of usability. Can such recognition and implications be taken for granted for UX, as UX evaluation methodologies and measures could be very different? * Analysis approaches developed by researchers are applied to a limited extent by practitioners. Such divorce between research and practice could be bitterer in UX analysis approaches, which are essentially lacking.

I-UxSED 2012 aims to address the above as well as other related ones.

Contributions, preferably with empirical studies, on the following topics (but are not limited to) are invited:

* Which artefacts of software development are useful as the basis for UX evaluation and how do such artefacts influence the selection of UX evaluation methods? * What are the forms and characteristics of UX evaluation feedback that are considered or proved useful and necessary for software development (including the UI design)? * How can UX evaluation methods be integrated in emerging techniques and approaches for software development (including the UI design)? * How do software designers'/developers' perceptions of UX evaluation feedback relate to their redesign strategies and approaches (e.g. prioritisation)? * How can the effectiveness of UX evaluation feedback in improving software quality be evaluated (i.e., the issue of downstream utility)? * How can analysis in UX practical evaluation be supported with techniques and tools applicable to actual industrial practices?

Submissions of 2 to 6 pages (SIGCHI format) describing a specific position or an empirical study are invited. Design, development and evaluation cases as well as theoretical frameworks relevant to the workshop topics are welcome. Each submission will be peer reviewed by the program committee members (see the list on the website). All submissions should be submitted as PDF files to EasyChair:


Accepted papers will be compiled as workshop proceedings downloadable from the TwinTide website (http://www.twintide.org/). A special issue on the topic "Interplay between UX Evaluation and System Development" in a prestigious HCI journal will be organised. Extended versions of selected papers from the workshop, upon going through the review process, will be included in it.

* Deadline for submission:     17th August 2012
