MIDGAARD - Connecting Time-Oriented Data and Information to a Coherent Interactive Visualization

== Description ==
In modern intensive care units (ICUs), the medical staff has to monitor a huge amount of high-dimensional and time-oriented data, which needs to be visualized user- and task-specifically to ease diagnosis and treatment planning. Available visual representations, like diagrams or charts neglect the implicit information as well as a-priory or associated knowledge about the data and its meaning (e.g., 38.5°C (101.3°F) is moderate fever and 41°C (105.8°F) is critical fever). Another challenge is to provide appropriate interaction techniques to explore and navigate the data and its temporal dimensions. In this context one major challenge is to connect time-oriented data and information to a coherent interactive visualization.

The goal of the Midgaard project [Bade et al., 2004] is to
*Present different interactive visualization techniques which enable the users to reveal the data at several levels of detail and abstraction, ranging from a broad overview to the fine structure.
*Introduce a time visualization and navigation technique that connects overview+detail, [[Pan|pan]]+[[Zoom|zoom]], and [[Focus-plus-Context|focus+context]] features to one powerful time-browser.

Challenges are the visualization of huge amounts of clinical parameters with respect to the temporal dimension (including occurrence time and valid time), measurement deviations, and trustability.
To overcome the problem of restricted display space Bade et al. use sophisticated visualization techniques.

'''Qualitative data''' is visualized by color-coded timelines similar to the [[LifeLines|LifeLines]] approach [Plaisant et al., 1996].

[[Image: Midgaard_colorcoded_timeline.jpg|450px]] 
Figure 1: Color-coded timelines to visualize qualitative data.

To visualize a '''quantitative data''' stream they combine quantitative representations of data with qualitative representations which is called hybrid technique. For instance a fever curve is enhanced with color-coded qualitative regions which add additional knowledge to the presentation, i.e. if a particular value is critical or not (see Figure 2).

[[Image: Midgaard_hybrid.jpg|450px]] 
Figure 2: Qualitative - Quantitative Hybrid: the fever curve is enhanced with color-coded qualitative regions.

When displaying '''high-frequency data''' the problem of limited space is even more critical. A huge amount of data values would have to be depicted at one small display region (e.g. a pixel or a row of pixels). Thus, they use a redesign of [[Tukey, John|John Tukey's]] box-plot - inspired by [Tufte, 1983]. The space between the minimum and the maximum is represented by a light color and the space between the 25% and 75% percentile is colored slightly darker; the median is marked as a black line. By these means, a lot of small box-plot-bars can be connected to a full data stream representation on very limited display space (see Figure 3).

[[Image: Midgaard_boxplot.jpg|450px]] 
Figure 3: A redesign of [[Tukey, John|John Tukey's]] box-plot - inspired by [Tufte, 1983]: allows for visualizing a full data stream of high-frequency data on limited display space.

The '''valid time''' of a data point is represented by a horizontal line indicating the data value over a specified period of time. If the granularity of the specified point in time differs from the granularity of the actual timeline scale of the representation (e.g. a more coarse or a more precise occurrence time) the point in time is represented by a small mark or by an extended mark capturing the uncertainties.

[[Image: Midgaard_validtime_granularity.jpg|450px]] 
Figure 4: The valid time of a value is represented by a gray horizontal line. The granularity of a data point (left: a more coarse occurrence time than the actual timeline scale, right: a more precise occurrence time) is represented by a small mark or by an extended mark capturing the uncertainties.

'''Measurement deviations''' (e.g. ± 1%) are represented by marking the corresponding range of values as illustrated in Figure 5.

[[Image: Midgaard_measurementdeviations.jpg|450px]] 
Figure 5: Visualization of measurement deviations (e.g. ± 1%): the corresponding range of values is marked.

The '''trustability''' of a data value is indicated by the fill level of a vertical bar plotted right above the data value.

[[Image: Midgaard_trustability.jpg|450px]] 
Figure 6: The trustability of a data point is represented by a green filled bar.

Midgaard can also be used to visualize the patient data in combination with treatment plans (treatment plans are indicated by gray areas in the background of the patient data) and it provides different views for physicians, nursing staff, and patients (see top right panel in Figure 7).

[[Image: Midgaard_screenshot.jpg|450px]] 
Figure 7: Screenshot of the Midgaard prototype.

== Advantages of Midgaard ==
*space-saving approach to visualize huge amounts of data – even high-frequency data
*visualization of patient data in combination with applied treatment plans
*visualization of values, occurrence time, valid time, measurement deviations, and trustability of parameters in one visualization
* aimed at visualizing intensive care data, but visualization techniques were also applied to the field of stock-exchange

== Disadvantages of Midgaard ==
* visualization of treatment plan characteristics (e.g. hierarchical structure, execution sequence, execution states, temporal uncertainties of execution) requires some learning effort

== Suitable Datatypes ==
* time-oriented data
* qualitative data
* quantitative data
* high-frequency data

== Interaction ==
* [[Filtering|filtering]]
* [[Semantic Zoom|semantic zoom]]: browsing through different visualization techniques and abstraction levels of the data from a broad overview to a fine structure (see Figure 8)
* [[Pan|pan]]+[[Zoom|zoom]] (in time)
* [[Focus-plus-Context|focus+context]]
* [[Details on demand|details on demand]]
