Serendipity, a trigger of exciting yet unexpected discoveries, is an important but comparatively neglected factor in information seeking, research, and ideation. We suggest that serendipity can be facilitated through visualization. To explore this, we introduce the Bohemian Bookshelf, which aims to support serendipitous discoveries context digital book collections. The Bookshelf consists five interlinked visualizations each offering unique overview collection. It at encouraging by (1)...
If visualization is to be democratized, we need provide means for non-experts create visualizations that allow them engage directly with datasets. We present constructive a new paradigm the simple creation of flexible, dynamic visualizations. Constructive simple-in skills required build and manipulate are akin kindergarten play; it expressive in one can within constraints chosen environment, also supports dynamics -- these constructed rebuilt adjusted. de- scribe conceptual components...
Self-reflection is a central goal of personal informatics systems, and constructing visualizations from physical tokens has been found to help people reflect on data. However, so far, constructive physicalization only studied in lab environments with provided datasets. Our qualitative study investigates the construction physicalizations people's domestic over 2-4 weeks. It contributes an understanding (1) process creating physicalizations, (2) types insights facilitated, (3) integration...
Evaluation is increasingly recognized as an essential component of HCI research. However, evaluation itself a changing research area. In particular, the many variations qualitative are emerging important empirical methods. This half-day tutorial designed for beginning to intermediate audiences. We will focus on basic methods analyzing data using mixture talks and hands-on activities. particular we consider closed open coding well clustering categorizing coded data. After completing this...
In this paper we discuss the creation of visual mementos as a new application area for visualization. We define visualizations personally relevant data purpose reminiscing, and sharing life experiences. Today more people collect digital information about their than ever before. The shift from physical to archives poses challenges opportunities self-reflection self-representation. Drawing on research autobiographical memory role artifacts in identified design mementos: mapping evoke...
In this article we explore visualization for personal storytelling and investigate techniques communicating subjective experiences in visual narratives. Personal stories are often storytellers omit, make up, or embellish details to craft engaging communicate a perspective. As growing data collections allow individuals leverage visualizations, how narratives can express subjectivity. From an analysis of visualizations created by enthusiasts, designers artists, collect deliberately expressing...
Personal visualizations have the great potential to provide benefits of everyone in their everyday lives. Their diverse goals combined with personal data they contain and contexts which are being used, however, make evaluation particularly challenging call for a wider perspective on empirical approaches. We need devise new methods adapt existing from other fields account specific challenges this emerging research area. An open-minded approach may help us gain more realistic understanding...
When searching through collections of books or written texts, the efficient yet limiting query paradigm is still most dominant entry point. Previous work characterizes search processes in various contexts and describes them as integral closely related to creative endeavours. We revisit this from a design perspective, proposing guidelines for versatile interfaces that are based on modular approach search. Inspired by aspects physical environments, our recommendations address learning,...
Stacked graphs are a visualization technique popular in casual scenarios for representing multiple time-series. Variations of stacked have been focused on reducing the distortion individual streams because foundational perceptual studies suggest that variably curved slopes may make it difficult to accurately read and compare values. We contribute this discussion by formally comparing relative readability basic area charts, ThemeRivers, streamgraphs our own interactive straightening baselines...
In this proposed panel, we will discuss the practice of Making with Data—the creating physical artifacts that represent a dataset. This topic lies at intersection several CHI communities: data visualization, fabrication, and tangible interaction. Our goal is to contemporary practices, but also envision future ways might continue make representations in future, given emerging fabrication techniques, representation desired interactions experiences data.
