This paper presents an initial investigation into the use of Tactons, or tactile icons, to present progress information in desktop human-computer interfaces. Progress bars are very common in a wide range of interfaces but have problems. For example, they must compete for screen space and visual attention with other visual tasks such as document editing or web browsing. To address these problems...

Recent advances in web-enabled graphics technologies have the potential to make a dramatic impact on developing highly interactive Geovisual Analytics applications for the Internet. An emerging and challenging application domain is geovisualization of regional (sub-national) statistics. Higher integration driven by institutional processes and economic globalisation is eroding national borders a...

Simple, cheap and green protocol for effective conversion of alcohols to corresponding carbonyl compounds in the presence of H14[NaP5W30O110] and ammonium nitrate is reported. The products were characterized by FT-IR and comparison of their physical properties with those reported in the literatures. The progress of the reaction was monitored by thin layer chromatography (TLC) technique. The ali...

Bunsen reaction was performed electrochemically using cation exchange membranes prepared by a radiation-induced grafting method for application to the iodine-sulfur thermochemical water-splitting cycle. The reaction experiments using sulfuric acid dissolving sulfur dioxide as the anolyte and hydriodic acid dissolving iodine as the catholyte verified the progress of the aimed reaction. Compared ...

In the present research, synthesis of butyl oleate ester from oleic acid and butanol using loofa-immobilized Rhizopus oryzae as a whole cell biocatalyst (LIC) was studied in which hexane was used as the hydrophobic solvent. Decrease of mass transfer limitations as result of the interface formation between the two immiscible substrates, positively affected on the reaction progress (87% as the es...

Over the years, competitions have been important catalysts for progress in Artificial Intelligence. We describe one such competition, the Trading Agent Competition for Supply Chain Management (TAC SCM). We discuss its significance in the context of today’s global market economy as well as AI research, the ways in which it breaks away from limiting assumptions made in prior work, and some of the...

A near ubiquitous feature of user interfaces is feedback on task completion or progress indicators such as the graphical bar that grows as more of the task is completed. The presumed benefit is that users will be more likely to complete the task if they see they are making progress but it is also possible that feedback indicating slow progress may sometimes discourage users from completing the ...

Users of information technology (IT) often encounter “progress indicators” during their interactions. These graphics (e.g., progress bars) appear on computing screens as users wait for a task to complete. The purpose of progress indicators is to inform users of the progress being made to complete a task. This study employs two theoretical models from psychological research on human waiting to d...

This paper is a contribution to the continuing development of the methods and results for the Index of Sustainable Economic Welfare, also known as the Genuine Progress Indicator (GPI). It attempts a more systematic approach to some of the components of the GPI. It includes a more careful specification of types of capital and more plausible methods of estimating the costs of depletion of non-ren...

Over the past two decades, organizational researchers have used and assessed the effectiveness of various Internet tools for conducting surveys. The various Internet tools used included email, the Web, and a combination of email and the Web. As with any evolving data collection tool, the use of various Internet tools must be carefully examined. This paper presents an overview of major issues th...
