Interactive systems in the mobile, ubiquitous, and virtual environments are at a stage of development where designers and developers are keen to find out more about design, use and usability of these systems. Ubiquitous Computing: Design, Implementation and Usability highlights the emergent usability theories, techniques, tools and best practices in these environments. This book shows that usable and useful systems are able to be achieved in ways that will improve usability to enhance user experiences. Research on the usability issues for young children, teenagers, adults, and the elderly is presented, with different techniques for the mobile, ubiquitous, and virtual environments.

As digital libraries expand in their proliferation, and as researchers, students, and consumers increasingly depend on them for their information needs, developers are keen to learn more about the design, use, and usability of these systems. ""The Handbook of Research on Digital Libraries: Design, Development, and Impact"" is the single academic reference work to provide comprehensive coverage of digital libraries. Through predictions of future trends, examinations of techniques and technologies, and focuses on users, interactions, and experiences, this in-depth collection provides developers and scholars with an extensive collection of research articles from the expanding field of digital libraries. It features: 56 authoritative contributions by over 130 of the world's leading experts on digital libraries from 25 countries; comprehensive coverage of each specific topic, highlighting recent trends and describing the latest advances in the field; more than 1,300 references to existing literature and research on digital libraries; and a compendium of over 370 key terms with detailed definitions. It is organized by topic and indexed, making it a convenient method of reference for all IT/IS scholars and professionals. It also features cross-referencing of key terms, figures, and information pertinent to digital libraries.

This book constitutes the refereed proceedings of the International Workshop on Altmetrics for Research Outputs Measurements and Scholarly Information Management, AROSIM 2018, held in Singapore, in January 2018. The 7 revised full papers presented together with two keynote papers and one introduction paper were carefully reviewed and selected from 20 submissions. The workshop will investigate how social media based metrics along with traditional and non-traditional metrics can advance the state-of-the-art in measuring research outputs.
