This paper is concerned with interaction design for visualization-based computational tools that support the performance of complex cognitive activities, such as analytical reasoning, sense making, decision making, problem solving, learning, planning, and knowledge discovery. In this paper, a number of foundational concepts related to interaction and complex cognitive activities are syncretized into a coherent theoretical framework. This framework is general, in the sense that it is applicable to all technologies, platforms, tools, users, activities, and visual representations. Included in the framework is a catalog of 32 fundamental epistemic action patterns, with each action pattern being characterized and examined in terms of its utility in supporting different complex cognitive activities. This catalog of action patterns is comprehensive, covering a broad range of interactions that are performed by a diverse group of users for all kinds of tasks and activities. The presented framework is also generative, in that it can stimulate creativity and innovation in research and design for a number of domains and disciplines, including data and information visualization, visual analytics, digital libraries, health informatics, learning sciences and technologies, personal information management, decision support, information systems, and knowledge management.

The rapid growth of the UX profession has led to an increased need for qualified practitioners and a proliferation of UX educational programs offered in both academia and industry. In this note, we present the design and initial evaluation of a new studio-based undergraduate program in UX--the first of its kind at a large, research-intensive US university. The program includes several curricular innovations, such as an integrated studio pedagogy in which six topical strands are interwoven across two types of studios. These studios are interconnected and span five semesters of the undergraduate experience. We present the curriculum model and the foundational principles that informed its design. We describe the two types of studios and their interconnection, and present early evaluation data showing that students are building valuable skills. The program described in this note provides a trailblazing model for UX pedagogy at the undergraduate level.

Engagement is an important aspect of user experience. While some researchers have investigated user engagement in the context of information visualization, there is still a lack of scholarship on the topic. In this paper we briefly explore the role and significance of user engagement in information visualization, and discuss challenges in its characterization and assessment. We present VisEngage, a self-assessment questionnaire that provides insight into 11 different characteristics of user engagement. We report the results of an online pilot study that was conducted using VisEngage, and reflect on its potential utility for visualization researchers and designers.
