The goal of this study is to examine the effect of user help seeking characteristics on their perception of library help design principles, formats and tools. Structural equation modeling (SEM) of a questionnaire survey results showed a number of significant regression relationships. Analysis of open-ended survey questions revealed existing user be...

In the face of increased cyber risks, we present our iterative design process and the resulting principles of SpringRain, an information visualization (infoVis) display design concept for large screens in network control rooms (NOCs). It aims to raise team situation awareness by visualizing large-scale multidimensional computer network datasets as...

We report findings from an assessment of e-book user experience (search and information seeking) from usage data and user tests. The usage data showed that most reading sessions were brief and focused on certain pages, suggesting that users mainly use e-books to find specific information. The user tests found that participants tended to use the def...

In this paper, we present a first-time cloud-based eco-feedback and gaming platform that aims to promote energy conserving thermostat-adjustment behaviors in multi-unit residential buildings. To achieve this goal, we introduce a new modeling approach for personalized eco-feedback design integrated with a collaborative social game to assist resident...

Problem-The demand for energy in the United States (US) is expected to grow 30% by 2030, while the aging grid suffers from increasingly costly outages [13]. As such, the US government and industry are looking for feasible ways to incentivize demand for renewables [13]. Problematically, energy in the US is an "invisible" good that only 44% of Americ...

In this paper, we discussed a case study on the user experience of a new PLM software system run in a Fortune 500 company. We list the common use cases and made guidelines to solve user experience errors of the software. Each guideline explains the context of the problem with title, explanation, and example included with direction for development i...

Modernizing the energy grid to a stable sustainable multi-directional energy generation, consumption and storage in the automated smart home context requires new forms of civic engagement. An interdisciplinary corpus of eco-feedback scholars have highlighted the potential for technologically mediated feedback to make people more aware and cognizant...

Along with environmental awareness, the interdisciplinary field of eco-feedback has become an active research interest Human Computer Interaction (HCI), Computing, and Sustainable Design. While designers face the challenge of designing complex socio-technical systems (Norman and Stappers 2015), eco-feedback lacks comprehensive theoretical contribut...

User experience (UX), with practical roots in Renaissance and theoretical beginnings in Modernism, is a contemporary design practice concerned with how users are impacted by their interaction with a product or a service. As design thinking has shifted from form based arts and crafts toward user-centered and user-serving profession, so have its meth...

Purpose Online help and tutorials are an important part of library services, yet they are often studied in specific contexts and disciplines like subject-specific research guides. The objective of this study was to examine users’ common preferences and expectations of library help channels in general and online help in particular. Design/methodolo...

Our ageing energy grid, the fundamental resource for human activity, remains one of the great societal challenges. Governments and the energy industry are visioning a future of an engaged society that sustainably produces and consumes energy via a shared multi-directional Smart Grid. This vision; however, depends on our current efforts to increase...

While usability tests have been helpful in evaluating the success or failure of implementing discovery layers in the library context, the focus of usability tests has remained on the search interface rather than the discovery process for users. The informal site-­‐ and context specific usability tests have offered little to test the rigor of the di...
