Information Visualization and Location-Based Services on Mobile Devices

With the widespread adoption of mobile devices and location-based services (LBSs), using location-based information from mobile devices has become increasingly common. However, accomplishing tasks on mobile devices remains challenging due to the complexity of location-based information and visualization constraints of mobile devices. Effective information visualization is, therefore, critical for improving user perceptions and usage. Based on theories of cognition and information visualization, we propose a novel hybrid approach that integrates presentation formats and interactivity features for information visualization. We implement the proposed approach on mobile devices and empirically evaluate it in a laboratory experiment. The results suggest that text- and map-based presentation formats significantly enhance user perceptions. Both semantic zoom and content filtering features have significant effects on perceived ease of use and perceived usefulness of mobile LBSs. Our theoretical and practical contributions, as well as plans for further testing and enhancing are discussed

Task-Technology Fit for Low-Literate Consumers: Implications for IS Innovations in the Developing Regions

More consumers in developing regions are using information systems (IS) to facilitate their work and increase productivity. This may imply that more low-literate populations in society are becoming the next billion IS consumers. Yet, how to adapt past IS literature in high-literate context to guide IS designs for low-literate consumers remains a gap. The current study, therefore, aims to apply and extend task-technology fit framework to investigate how IS can be designed to meet the needs and mitigate the constraints of low-literate consumers. Due to the novelty and complexity of the foci phenomenon, a mixed-method approach was adopted to gain in-depth understanding of the proposed research framework. The current paper is a research in progress that aims to make several major theoretical and practical contributions to the social innovation and IS design fields

How Does Mobile Computing Develop Transactive Memory in Virtual Team? A Social Identification View

The advancement in mobile computing technologies has shown great potential to drive efficiency and effectiveness of knowledge work in virtual teams. Despite their ubiquity, theoretical and empirical research investigating the impact of mobile computing artifacts on development of transactive memory in virtual teams is in its infancy. Drawing on the social psychology literature, we propose a social identity based view to understand how the use of mobile computing artifacts is associated with the development of transactive memory system (TMS) in virtual teams. Specially, the use of four categories of mobile computing artifacts (i.e., ubiquitous co-presence, status disclosure, context search, and customized notification) is proposed to enhance social identification, which thereafter promotes TMS development in terms of specialization, credibility, and coordination. This study offers a new perspective on the mechanisms through which mobile computing artifacts facilitate TMS development, and it yields important implications for the design of mobile strategy in organizations

Mobile ICT and Knowledge Sharing in Underserved Communities

Organizing principles, exchange relationships, and technology affordance of underserved communities in emerging markets are different from privileged communities, which have been the focus in traditional information systems literature. This paper investigates mobile ICT and knowledge sharing in a rural farming community in India. Our qualitative field study reveals that value creating and value claiming norms are key enablers of knowledge sharing in underserved communities. The findings also identify the communication mechanisms and challenges of mobile ICT innovations that foster knowledge sharing among dispersed underserved communities. We discuss the implications for theory and suggest a practical guide to enhance knowledge sharing in underserved communities

Diverse Geological Evolution of Impact Basins on the Moon

Impact basins are the dominant landforms on the lunar surface, and their geological evolution varies. This research studied the diversity in the geological evolution of three impact basins: the Dirichlet–Jackson Basin, the Nectaris Basin, and the Orientale Basin. First, the regional topography and geomorphology of the three basins were studied using the SLDEM2015 digital elevation model (DEM). Clementine ultraviolet–visible (UVVIS) data and Moon Mineralogy Mapper (M3) data were used to study the chemical composition and mineralogical composition of the three basins. Additionally, the lunar crust thickness data have been used to study the subsurface structure of the three basins. The topographical analogies of the three basins indicate that the shapes of the basins are cavity-like. However, the shape of the Dirichlet–Jackson basin is not an obvious cavity compared with the other basins. The positions with minimum and maximum crustal thickness of the three basins are located at the center and the rim. The uplift of the crust-mantle interface of the Nectaris Basin and Orientale Basin is relatively larger than in the Dirichlet–Jackson Basin. Below the center of the maria of the Nectaris Basin and Orientale Basin, collapses occurred at the crust–mantle interface. The concentrations of FeO and TiO2 in the non-mare formation of the basin and maria show expected bimodal distributions. Moreover, we found exposures of olivine-rich materials in the Nectaris Basin and Orientale Basin which are located in the Rosse and Maunder craters, respectively. These exposures of olivine may be explained by the fact that the formation of the large impact basin, which might penetrate and blast away the upper lunar crust, excavating deep-seated material
