Making sense of a body data is common activity in any kind analysis. Sensemaking the process searching for representation and encoding that to answer task-specific questions. Different operations during sensemaking require different cognitive external resources. Representations are chosen changed reduce cost an information processing task. The power these representational shifts generally under-appreciated as relation between retrieval.
Making sense of the world using information technology has become a ubiquitous activity in digital era. Sensemaking, as to make sense, suggests an active processing achieve...
Background During a global pandemic, it is critical that the public able to rapidly acquire new and accurate health information. The internet major source of eHealth literacy ability individuals find, assess, use information available on internet. Objective goals this study were assess coronavirus-related examine relationship between COVID-19−related knowledge, attitudes, practices (KAPs). Methods We conducted web-based survey representative sample 1074 US adults. adapted 8-item Literacy...
Assessing the trustworthiness of information online is complicated. Literacy-based paradigms are both widely used to help and critiqued. We conducted a study with 35 Gen Zers from across U.S. understand how they assess online. found that tended encounter—rather than search for—information, those encounters were shaped more by social motivations truth-seeking queries. For them, processing fundamentally practice. interpreted together, as aspirational members groups. Our participants sought...
Students who registered for the Mapping with Google massive open online course (MOOC) were asked several questions during registration process to identify prior experience eleven skills as well their goals registering course. selected from a list; they periodically reminded of these MOOC. At end course, we compared students' self reports goal achievement on post-course survey behavioral click-stream analysis. In addition, assessed how skill in subject predicts student's completion and found...
In order to maximize online reading performance and comprehension, how should a designer choose typographical variables such as font size type? This paper presents an eye tracking study of type affect reading. between-subjects design, we collected data from 82 subjects stories formatted in variety point sizes, san serif, serif fonts. Reading statistics speed were computed, post-tests comprehension recorded. For smaller fixation durations are significantly longer, resulting slower – but not...
A trio of systems illustrates the challenges designing large displays for use in ubiquitous computing environments that are, indeed, unremarkable.
Research in the field of large-display groupware applications has yet to yield a killer app, common look and feel for applications, or set broadly applicable design principles. It's therefore difficult understand what constitutes successful application affects their adoption. Although faces many same adoption use challenges as conventional desktop groupware, how people perceive interact with yields some unique challenges. We've built evaluated several systems that address various workgroups,...
Background Vaccination against COVID-19 is an important public health strategy to address the ongoing pandemic. Examination of online search behavior related vaccines can provide insights into public's awareness, concerns, and interest regarding vaccination. Objective The aim this study describe during start vaccination efforts in United States. Methods We examined Google Trends data from January 1, 2021, through March 16, determine relative volume for vaccine-related searches on internet....

Capturing and analyzing the detailed eye movements of a user while reading web page can reveal much about ways in which occurs. The WebGazeAnalyzer system described here is remote-camera system, requiring no invasive head-mounted apparatus, giving test subjects normal use experience when performing web-based tasks. While many such systems have been used past to collect gaze data, brings together several techniques for efficiently collecting, re-analyzing data. We briefly describe overcoming...
Large-scale session log analysis typically includes statistical methods and detailed examinations. While both have merits, can miss previously unknown sub- populations in the data analyses may selection biases. We therefore built Session Viewer, a visualization tool to facilitate bridge between analyses. Taking multiple-coordinated view approach, Viewer shows multiple at Aggregate, Multiple, Detail levels support different styles. To levels, provides fluid traversal side-by-side comparison...
As has been apparent for the past several months, MOOCs (Massive Online Open Courseware) have emerged as a powerful contender next new education technology. Yet landscape of technology is littered with remains previous technological breakthroughs that failed to live up their initial promise, or at least rhetoric. This panel will present lively debate about and realities, whether they are transformative, merely faddish trend.
The Future Conversations workshop at CHIIR'21 looked to the future of search, recommendation, and information interaction ask: where are opportunities for conversational interactions? What do we need get there? Furthermore, who stands benefit? was hands-on interactive. Rather than a series technical talks, solicited position statements on opportunities, problems, solutions in search all modalities (written, spoken, or multimodal). This paper -co-authored by organisers participants workshop-...
Instant messaging (IM) in the workplace has proven to be a valuable tool for facilitating informal communication. Its benefits, however, are generally limited times when users front of their computers. Because so much work takes place while people mobile within workplace, we sought extend benefits IM beyond people's personal machines and into publicly accessible groupware. We first conducted study large display groupware applications (LDGAs) understand affordances that displays offer...
Short assigned question-answering style tasks are often used as a probe to understand how users do search. While such simple test and effective at eliciting the particulars of given search capability, they not same naturalistic searches. We studied quantitative differences between self-chosen "own" finding that behave differently when doing their own tasks, staying longer on task, but making fewer queries different kinds overall. This implies user's should be testing user behavior in...
Hypertext systems are used for a variety of representational tasks, many that involve fairly formalized structures. Because hypertext generally intended developing informal (unstructured data) and semi-formal (semantic networks) structures, more formal structures can be difficult. Regular patterns in must often recreated from primitive elements (individual nodes links) resulting high overhead cost. In this paper we describe the Instructional Design Environment, or IDE, system application...
