The most depend on the monitoring goals. A key decision is whether common example is a map display, where we want to compare interrupts should be cognitively or system generated. The same problem occurs with more abstract data, for example, in large network diagrams. VTDP: Cognitive Reconstruction Any pattern comparison involves loading some aspect of one Most analysts will have their work frequently interrupted.

Pattern comparisons are far more efficient new data becomes available. Successfully resuming a prior if the transfer of attention between one pattern and another can analysis requires that the entire cognitive system be be made using eye movements, because in this case the reconstructed and this involves rebuilding both the machine information only needs to be held for a fraction of a second.

All long term memory is more a The working memory burden is far greater when other process of reconstruction than a process of retrieval. Any full techniques, such as zooming, are required for the comparison. Adding extra annotations and many packages support the resurrection of a magnifying windows is a common way of ensuring that the prior analytic system state through the use of scripts.

One way of dealing with the pattern comparison problem is G. This Often analysts start with a piece of information and follow method relies on a degree of interest function whereby the links outward [8]. For example, in social networks we may computer attempts to show only task relevant information and follow a chain of social relationships. Or we may trace hides or shrinks other information.

The success of this method linkages between people through an organization. Lateral depends entirely on the predictability of related information. Perhaps in K. VTDP: Multidimensional Dynamic Queries IV3 III most cases, analysts begin by finding a lead, in the form of a CHA9 piece of information that seems relevant, then follows links With multidimensional discrete data all entities have the laterally to find related information, assembling what is same set of attributes.

The attributes define the data relevant and discarding what is not. One of the simplest dimensions and each entity can be thought of as a point in a instances of this is a search for related information within a multidimensional space. A set of sliders is provided that can large network.

Each slider adjustment is an epistemic action, narrowing the range of what H. The method has most often been substantial amount information on the screen at once but used with scatter plots and to a lesser extent time series plots, because of its density it cannot all be made legible. A simple but it can work with ranges displayed on maps and with node interaction solves the problem; touching an object causes both link diagrams. The highlighted objects may also reveal addition detail.

As with the L. VTDP: Table Data - Sort and Compare hierarchical aggregation, graphical information scent is needed Tables of data can contain glyphs instead of just numbers, to provide a starting point for visual search. As a first order in which case they become interactive visualizations. A approximation, degree-of-relevance highlighting is useful for common analytic strategy is to use sorting to bring out certain between 30 and graphical symbols representing data.

For example, The data inventory process will almost certainly start to suppose we have a data table with system failures represented blend into step 3, task refinement, because data is only by a glyph in one of the columns. If failures tend to occur when important as it relates to task requirements.

Step 3: Refinement of cognitive task requirements table where they can be visually compared to values in other As the data is understood, the set of tasks can be refined. The following IV. In the solutions are discoverable through a visual pattern search.

Once a set of subtasks that is amenable to visual thinking A. Step 1: High level cognitive task analysis solutions has been identified, they can be matched to the At the start of the design process the team members must VTDPs and their associated visualizations. Initially the description should not specify the D.

Step 4: Identification of VDTPs and visualizations that can implementation method so as not to prejudge the solution. This step is the key creative stage in the design process. It is best led by an experienced designer who knows both the B. Step 2: Data inventory types and nature of visualization and understands the VTDPs It is important to know early on in the process what data is that can be used to make them cognitively efficient. Sometimes confidentiality can be a stumbling block.

Data can be every problem. Fortunately, there are only a small number of enormously varied in its properties, but the following list basic types of visualizations that have widespread use in contains some of the attributes that are likely to appear in any practice, namely charts, maps, node link diagrams and tables.

These are can be provided in component libraries. Step 5: Design decision rules dimensional discreet. For example, we have data may require new infrastructure; some data has constructed the system of rules below regarding techniques that explicit costs; some data has security issues. Oculus Aperture studio [13]. Aperture provides an open and extensible Web 2. Start with example, computer finds similar — user node-link diagrams and charts of various kinds such as scatter selects to refine query.
