Business Information Visualization

With the flood of data produced by today\u27s information systems, something must be done to allow business decision-makers to extract the information the data contains. The recent advances in visualization technologies provide the capability to begin to use human visual/spatial abilities to solve the abstract problems found in business. If business problems can be visualized with an appropriate representation, then it may be possible to use innate spatial/visual abilities to allow the business decision-maker to separate the wheat from the chaff. This tutorial surveys the issues related to applying visualization technologies to business problem solving

Group cognitive mapping: a methodology and system for capturing and evaluating managerial and organizational cognition

Organizations would like to capture and merge the perceptions of key individuals into an organizational memory. Various cognitive mapping approaches have been used to identify and capture these perceptions. However, merging the cognitive maps of individuals into a collective cognitive map to represent the shared perceptions has been problematic. Due to the merging problems, the creation of collective cognitive maps is impractical for many organizational situations. In this paper, we describe and demonstrate a cognitive mapping based methodology and system that eliminates the merging problem, supports data collection, and provides data analyses to uncover both individual and collective cognitive maps.Cognitive mapping Managerial and organizational cognition Group support systems Group decision-making

Evaluation of a Financial Portfolio Visualization using Computer Displays and Mixed Reality Devices with Domain Experts

With the advent of mixed reality devices such as the Microsoft HoloLens, developers have been faced with the challenge to utilize the third dimension in information visualization effectively. Research on stereoscopic devices has shown that three-dimensional representation can improve accuracy in specific tasks (e.g., network visualization). Yet, so far the field has remained mute on the underlying mechanism. Our study systematically investigates the differences in user perception between a regular monitor and a mixed reality device. In a real-life within-subject experiment in the field with twenty-eight investment bankers, we assessed subjective and objective task performance with two- and three-dimensional systems, respectively. We tested accuracy with regard to position, size, and color using single and combined tasks. Our results do not show a significant difference in accuracy between mixed-reality and standard 2D monitor visualizations
