HCI Prototypes and Knowledge Contribution

In HCI/interaction design research, much of our work is prototype-driven. We explore new concepts through the design of new interactive systems. Still, as a field of research we lack documented methods for examining the relation between design ideas and design manifestations although this ability to examine if a design (idea) is new and novel contribution to our field of research is crucial. This paper contributes to this need by proposing ‘generic design thinking’ as a first step towards a method to move from ideas and designs to classes of conceptualized designs. In short, a method for examining designs as knowledge contributions in HCI/interaction design research. We argue for this suggested method through two examples including 1) how one such method can be used to analyze and conceptualize existing designs, and 2) how one such method can be useful for working with new concepts, and the generation of new knowledge through design. We conclude with a discussion on how our initial sketch of one such method can facilitate systematic knowledge development in HCI design research.

Method to Unfold the Connotation and Denotation in User Interfaces

This study introduces an approach for evaluating user interfaces built on visual rhetoric and the rhetorical notion of function. A personal informatics mobile application has been selected to exemplify the application of this approach. Through the results of this example evaluation, this paper discusses the consequence of applying a rhetorical evaluation to a user interface. In this discussion, it is observed that inspecting the function performed by interface components takes into account experiences, communication, and meaning. In addition, it fosters reflection and criticism

Use of Rhetoric for HCI/UX Pedagogy and Analysis

In this paper, we introduce a first pass of a rhetorical handbook intended for UI/UX designers. This handbook is based on an earlier version for graphic designers, introduced by Ehses & Lupton in 1988, in which diverse rhetorical concepts are illustrated through graphic work. For the UI/UX version, we examined desktop, web and mobile interfaces in order to illustrate the same concepts. In this first pass, we observe that the three modes of appeal (i.e., pathos, ethos and logos) fluctuate throughout the user experience. Additionally, we learned that rhetorical operations aid describing the adjustments made on an interface to work in different platforms. Further, the rhetorical figures (tropes and schemes) help to describe conceptually the interface’s composition and interactions. The concepts presented in the handbook provide a framework to examine and critique user interfaces, through which the disciplines of user experience and rhetoric connect.

Software as Persuasive Visual Argument

By examining application software as a type of rhetorical artifact, it is possible to highlight its social, ethical and moral implications. In this paper, we explore one possibility for such a lens: application software functioning as a visual enthymeme. To explore the applicability of that concept in HCI, we analyze one web application as a first step. In our analysis, we observe that interaction and usability are two features that support an application in functioning as a visual enthymeme. Also, online sharing could help the user take the role of the arguer. Our analysis allows us to outline the elements of a user-centric persuasive experience and shows promise for further explorations regarding the applicability of rhetoric in HCI.

HCI as Fashion

Recent research shows that fashion already exists in the HCI domain and influences and affects design and designers’ thinking and practices throughout the design process. In this study, we draw our insights from fashion related research within HCI and interaction design, provide some observations about fashion-related design and research practices, raise questions about our field as moving forward towards fashion driven discipline.

UX, Security, and Complex Systems

Securing Information and Communication Systems (ICSs) is a highly complex process due in large part to the feedback relationship that holds between the users and the system and its ‘ecosystem’ of usage. Such a relationship is critical for experience designers. The design of secure systems can thereby be enhanced by using principles from disciplines where similar relations hold, such as security engineering and adaptive systems. In this work, we propose a user experience design framework based on six principles and use a social networking system as an example of its application. The proposed design principles are grounded in complex systems theory. We address several potential security and privacy challenges inherent in the design of a large-scale adaptive system. By means of this framework, we reflect upon the participation of an experience designer regarding the conceptualization, selection, review, and update of security and privacy matters. In this sense, we observe the role of the designer as a translator across disciplines. By introducing our framework, we also attempt to start a conversation about the challenges a designer faces in the appropriation of this role, either for the case of securing large-scale systems or in those situations where the boundaries of design and knowledge from other disciplines already overlap.

Storytelling in HCI and UX

As designers, we tell stories as we engage in the design process. But how does one story differ from another? Are there storytelling types used during different parts of the process? What form and function do these stories take? In this paper we explore the nature of storytelling in the context of design and how it plays different roles throughout the process: (1) during research to explain user stories; (2) during ideation to expand the design space and explore problems; (3) as a prototyping tool; and so on. We also will describe inappropriate uses of storytelling in the design process; for example, telling pristine and unreal stories rather than keeping the story roughly right.

Temporal Anchors in User Experiences

As HCI becomes more aware of long-term use experience, users’ retrospection might be one starting point to explore prior interactive use. However, due to the limitation of current methodologies and human memory, research participants might recall specific prior use episodes and less their experience over time. In this note, we examine how to encourage retrospection and reflection concerning the changes of use experience in the past and over time. We have reviewed relevant research and traced the usage of temporal references in those studies, such as diagrams of use measurement over time or the history of interactive products. We propose the notion of temporal anchors as way of capturing and grounding temporal aspects of long term use experience. We have found that methods that include temporal anchors have facilitated opportunities for rich reflections and communications around use experience and temporality.

Evolution of Design Competence in UX Practice

There has been increasing interest in the adoption of UX within corporate environments, and what competencies translate into effective UX design. This paper addresses the
space between pedagogy and UX practice through the lens of competence, with the goal of understanding how students are initiated into the practice community, how their perception of competence shifts over time, and what factors influence this shift. A 12-week longitudinal data collection, including surveys and interviews, documents this shift, with participants beginning internships and full-time positions in UX. Students and early professionals were asked to assess their level of competence and factors that influenced competence. A co-construction of identity between the designer and their environment is proposed, with a variety of factors relating to tool and representational knowledge, complexity, and corporate culture influencing perceptions of competence in UX over time. Opportunities for future research, particularly in building an understanding of competency in UX based on this preliminary framing of early UX practice are addressed.
