Fundamental recommendations in figuring out info were elusive for a very long time. the sector of synthetic Intelligence has proposed the Turing attempt that allows you to try out for the "smart" behaviors of machine courses that express human-like characteristics. corresponding to the Turing try out for the sphere of Human­ details interplay (HII), getting info to the folks that desire them and assisting them to appreciate the knowledge is the hot problem of the net period. In a quick period of time, the infrastructure of the internet grew to become ubiquitious not only by way of protocols and transcontinental cables but additionally when it comes to daily units in a position to recalling network-stored info, occasionally twine­ lessly. hence, as those infrastructures develop into fact, our awareness on HII concerns must shift from details entry to info sensemaking, a comparatively new time period coined to explain the method of digesting info and figuring out its constitution and intricacies to be able to make judgements and take action.

Sample text

The framework facilitates a new way of exploring the space of visualization operators. Using the Data State Model, this method forms the basis of an evaluation technique for operators in visualizations. By applying this operator analysis to various visualizations, we can point researchers toward areas where particular operators are missing from a given system or technique. We can also use this model to compare different interaction models in visualizations. This will enable other researchers to characterize various interaction techniques, and capture design requirements for new application domains, and develop new and novel operators.

We will then use this framework in the visualization spreadsheet. We discuss properties of this framework and use it to characterize operations spanning a variety of different visualization techniques. The model developed here enables a new way of exploring and evaluating the design space of visualization operators, and helps end-users in their analysis tasks. 13 E. H. Chi, A Framework for Visualizing Information © Springer Science+Business Media Dordrecht 2002 14 1. A FRAMEWORK FOR VISUALIZING INFORMATION The Need for a Reference Model for Operations Imagine a visualization application with two views of the sarne source data set, say a HorneFinder application [2], In this application, the user is to find a potential horne to purchase using a nurnber of criteria, such as the nurnber of bedroorns, geographical location, price, etc.

We examined recent work on visualization interaction frarneworks and then developed a novel operator and user interaction model. Our Data State Model unifies the data analysis process and the complex relationship between view and value to characterize the interactive and non-interactive operations in a visualization system. For example, using the Data State Model as a basis, we developed a way to classify operators. We examined not just view and value, but how intermediate data and visualization abstractions are generated in the analysis process.
