Decisions involve many intangibles that need to be traded off. To do that, they have to be measured along side tangibles whose measurements must also be evaluated as to, how well, they serve the objectives of the decision maker. The Analytic Hierarchy Process (AHP) is a theory of measurement through pairwise comparisons and relies on the judgements of experts to derive priority scales. It is th...

Vispol (Visualization for the police) is an interactive graph-based visualization that supports the work of the police of Hessen, Germany. A Vispol graph visualizes involved persons and their relations in crisis incidents like hostage takings or bank hold-ups. It presents a tabletop-based multi-touch and tangible user interface for the structured creation and manipulation of node-link diagrams....

The quality of outsourced IT services can be traced to attributes of the services such as tangibles, responsiveness, reliability, assurance, and empathy. The relative impact of these attributes on client satisfaction varies across different IT services (applications, data center, EUC support, network administration, and help desk), and one or few attributes stand out as “drivers” of client sati...

Very few studies have investigated the service quality of the system development process. In this study, an instrument based on SERVPERF's service quality dimensions, i.e., tangibles, reliability, empathy, responsiveness, and assurance, was developed to study the service quality for in-house and outsourced system development process. Analysis of the data collected from 152 system users who had ...

Tangible User Interfaces (TUIs) allow interaction with computer applications using physical objects called tangibles. TUIs have a number of latent advantages over traditional user interfaces including spatial naturalness and immediate haptic feedback where users receive both tactile and digital responses from computer systems. This paper presents the preliminary design and test results of a tab...

Co-located tabletop tangible user interfaces (TUIs) for music performance are known for promoting multi-player collaboration with a shared interface, yet it is still unclear how to best support the awareness of the workspace in terms of understanding individual actions and the other group members actions, in parallel. In this paper, we investigate the effects of providing auditory feedback usin...

With the rapid development of electronic commerce, the public demand for express delivery is increasing, however, there are still lack of service quality and high service complaint ratein the process of rapid development. Based on the SERVQUAL model, this paper analyzes the current situation of the whole express service industry quality, From five aspects: tangibles, reliability, responsiveness...

h S T R A C T IMPROVINGTHE QUALITY OF PUBLIC SERVICES involves quantifying patron perceptions. Using a questionnaire devised by Van House, Weil, and McClure (1990);combining it with the concept of service dimensions and service imperatives based on the work done by Berry, Zeithaml, and Parasuraman (1990); and coding patron comments from the questionnaire as either positive or negative; this pro...

This work is part of a research targeted at experimenting the use of physical artifacts for the retrieval of multimedia information. Tangible interfaces – that couple physical artifacts to digital data – are described in different research works, and a number of studies focus on tangibles for children. In spite of that, most of the work done for the kids is related to gaming or learning. This w...

La musique est une activité productrice de sons, prenant place dans un environnement où se croisent pratiques tangibles (travail l’instrument, écriture musicale, matérialité du spectacle) et intangibles (propriétés sonore, singularité l’expérience volatilité la performance). Cet article propose d’explorer façon dont ce croisement contribue à revisiter tradition culturelle, ici celle des défilés...
