DESCRIPTION :
The PhD candidate will join the Inria centre of the University of Lille and be part of the LOKI research group, specialized in Human-Computer Interaction. It is affiliated with the CRIStAL laboratory (UMR 9189) and includes professors and assistant professors of the University of Lille, as well as Inria researchers. Lille is at the northern tip of France and its metropolitan area, situated at the crossroads of northern continental Europe, is the 5th biggest in France. Loki is a dynamic and multicultural team with members coming from different countries (Germany, Canada, China, Iran, France, etc.) and communicating daily in English., Interactive systems can be tailored by end-users, for instance by modifying command layouts, to better match their needs and preferences. While this might be beneficial by increasing productivity for certain tasks, it can also be detrimental if layouts of commands break design logics and are changed too often. This project aims at tackling two challenges. First, we will (1) study how interfaces currently promote tailoring possibilities and how it can be improved. Then, we will (2) study the actual quantitative and qualitative impact of tailoring actions on end-users workflows, with a specific focus on the impact and duration of the tailoring actions and their effects., Interactive systems' designs often focus on stereotypical tasks to provide tailored actions such as browsing the web, editing virtual documents, or reading and sending emails. This approach relies on a one-size-fits-all strategy and fails to accommodate various use cases and preferences. For instance, users may need to personalize systems' toolbars (e.g., Mozilla Firefox, MS Word, Affinity Designer) to expose hidden commands or reduce cluttering to adapt the interface to their tasks, or to automate email management to sort and filter them out, which we refer to as tailoring tasks. While some systems facilitate automation with extensions (e.g., Firefox) or modify their source code to change their layout and more (e.g., Emacs), knowing what can be changed, when it can be beneficial to do so, and engaging in tailoring tasks to customize or extend their functionalities remain major challenges.
A major challenge is the lack of signifiers exposing possibilities and opportunities to tailor a system. Some signifiers exist in current interactive systems (see examples in Affinity Designer 2 on Figure 1). Yet, they may not convey enough information on the tailoring actions they signify, and be too subtle to be noticed. Furthermore, they mostly support real-time modifications and do not particularly adapt to tailoring in anticipation of future needs, or in reflection of tasks already performed; e.g., indicate commands that were not used in the last working session that could be potentially hidden to free space up.
Another challenge is to identify and assess the actual quantitative and qualitative benefits of tailoring software features and behaviors. While changes may be perceived as beneficial by end-users, they may actually create conflicts with the original design of an application and fail to follow structural rules that ensure logical consistency; e.g., users could hide commands that are not required on the short-term but required on the long-term.
One potential focus could be on use cases of interface layouts personalizations. Such personalizations can expose commands and reduce cluttering and be beneficial on the short and long term, but also detrimental if significant commands disappear or the task change
Principales activités
We consider the following questions in this project:
1. When should information be provided about tailoring possibilities, how to provide incontext information, and what interactive means support end-users in knowing about tailoring possibilities?
2. What impact can have tailoring actions on users' workflows with regard to performance and satisfaction, both positively and negatively?
Regarding the first question, a possible exploration is to study means to convey in-context information of tailoring possibilities and create a design space of visual signifiers conveying information on tailoring tasks, building on our previous work. The candidate could study when signifiers should be provided, and whether they must adapt to tailoring tasks in anticipation of significant events (e.g., preparing email filters for a project), in timing with them (e.g., creating a shortcut for a command when using it), or in reflection of significant events (e.g., creating a code snippet after writing structured text).
The candidate will:
* review the literature on software appropriation and the state-of-the-art with regard to software design
* analyze this corpus to identify categories of tailoring tasks and signifiers
* conceptualize a design space of signifiers with a focus on timing
* run experiments to assess their benefits and drawbacks
* report on this work by publishing papers in international conferences
