Knowledge workers spend significant time finding, understanding, and relating information from different web pages. This process often leads to cluttered workspaces requiring active management of web pages, their evolving relevance, and relationships. Existing approaches, such as bookmarking systems, are often too rigid and impose considerable cognitive effort to create and maintain. In this work, we identify key design concepts to capture and retrieve the emerging and dynamic structures of web pages. In a field experiment with 29 knowledge workers (primarily students and IT professionals), we investigated current web management practices over time before we deployed our technology probe (Gstell) to explore initial behavioral adaptation to our design concepts in practice. Our analysis showed that many participants frequently struggle with excessive but inactive browser tabs and that the design concepts can alleviate the overload and improve focus. We discuss design considerations for more sustainable web page management.

Expressing oneself appropriately in online meetings through non-verbal cues can be challenging for knowledge workers. Automatic non-verbal cue detection technologies have the potential to support workers' self-presentation efforts through real-time feedback, but little is known about workers' reactions to and the implications of doing so. We designed and implemented Novecs as a technology probe of a real-time feedback display that automatically detects and signals users' own non-verbal cues -- smiling, nodding, gaze, and posture. Novecs was deployed in an exploratory field study (n=18) to support knowledge workers' self-presentation in their everyday meetings. Post-study interviews reveal how Novecs' real-time feedback helped increase in-the-moment self-awareness, and how neutrally-framed feedback may help navigate tensions between authentic and in-authentic self-presentation. Participants also emphasized the need for natural timing when adjusting non-verbal cues in-meeting. We discuss design opportunities and challenges of real-time, non-verbal cue feedback systems, such as personalizing feedback based on different meeting types.

Software developers spend about a quarter of their workday using the web to fulfill various information needs. Searching for relevant information online can be time-consuming, yet acquired information is rarely systematically persisted for later reference. In this work, we introduce SALI, an approach for semi-automated inline linking of web pages to source code locations. SALI helps developers naturally capture high-quality, explicit links between web pages and specific source code lo-cations by recommending links for curation within the IDE. Through two laboratory studies, we examined the developer's ability to both curate and consume links between web pages and specific source code locations while performing software development tasks. The studies were performed with 20 subjects working on realistic software change tasks from widely-used open-source projects. Results show that developers continuously and concisely curate web pages at meaningful locations in the code with little effort. Additionally, we found that other developers could use these curations while performing new and different change tasks to speed up relevant information gathering within unfamiliar codebases by a factor of 2.4.
