===Description===

== Visual Mapping ==

=== Introduction ===
The aim of the visual representation with tile maps is to abstract and simplify seasonal patterns. This makes it easier to recognize patterns or to compare them.

=== Visualisation / Abstraction ===
With this visualisation technique the measured data (in our case weather) is represented by "tiles" (squares) which are aranged in 2 dimesions. Every "tile" is representing a certain amount of time. E.g. the images above showing a tile map where every "tile" representing a day which are vertically grouped into weeks. So the chronological sequence is illustrated vertical, from top to bottom, and horizontal, from left to right ... like a 90 degree rotated calendar. The tile map can also be used to display other temporal patterns. For example, displaying diurnal patterns would work much the same way, except each tile represent an hour of the day and would be vertically grouped into days. [Mintz et al., 1997]

The value of the measured data is illustrated by the color or color intensity of the "tiles". For example a light shade indicating low values, darker shades indicating higher values. [Mintz et al., 1997]

== Interaction practices ==

=== application building ===

1. Load the data to be visualized into prefuse's data structures, either reading in data from a file, loading data from a database, or through a custom data source.
2. Create a Visualization that maps the loaded data to a visual abstraction. Tables, Graphs, and/or Trees are added to the Visualization and given a unique data group name for later reference.
3. Create a RendererFactory and register it with the Visualization. The factory is responsible for assigning Renderers to VisualItems.
4. Construct a series of data processing Actions that operate on the visual abstraction. These operations can involve just about anything, but common examples include setting the location, color, size, and shape of visual items or animating these properties between different configurations. These Action instances can be grouped into ActionLists for performing various processing tasks. Actions that will be invoked directly are added to the Visualization and given a unique name by which they can be referenced.
5. Initialize one or more interactive Displays for viewing and manipulating visual items. Specify interactive behaviors by adding Controls to the Displays. Search and filtering over data items can be added using dynamic query bindings.

=== Visualisation / Abstraction ===
With this visualisation technique the measured data (in our case weather) is represented by "tiles" (squares) which are aranged in 2 dimesions. Both dimensions represent time. Compared to a 2-dimension coordnate system, we could say the x-axis is always one step bigger than the y-axis, which is used for displaying more details ( e.g. x-axis or from left to right: every step or tile representing a week; y-axis every step or tile representing one day ... like a 90 degree rotated calendar )

The value of the measured data is illustrated by the color or color intensity of the tiles. For example a light shade indicating low values, darker shades indicating higher values. [Mintz et al., 1997]

UE-InfoVis0607 0027217: /* Usage */

== Definitions ==
{{Quotation|The Alphaslider is used to rapidly scan through and select from lists of alphanumeric data. The essential components of an Alphaslider are a slide area, a slider thumb, a text output and an index to the elements that the slider operates over. Whereas a traditional slide area lets users page through the content of a scrolling list, the Alphaslider slide area lets users move directly to a certain part of the slider range by clicking in it.|[Ahlberg, Shneiderman, 1993] }}

{{Quotation|A Compact and Rapid Selector|[Ahlberg, Shneiderman, 1993]}}

== Usage ==
[[Image:Galphai.gif|thumb|200px|right|Alphaslider]]
The AlphaSlider interface was originally devised in 1993 and promoted by Ahlberg and Shneiderman. The essential components of the AlphaSlider are the same as that of the drop-down listbox. There is a slider area, a slider thumb (the square in the middle that a user can directly drag on), and left / right arrow. To find the result, just drag the slider thumb left or right, or use the left / right arrows. For a big amount of output or a small slider area, the thumb isn't very exact, so the arrows are good for "fine tuning" the result.

The small size of the Alphaslider allows it to be placed on mobile devices, on a credit card, on a control panel for a VCR, or as a widget in [[direct manipulation|direct manipulation]] based database interface.
[Osada et al., 1993]

== Conclusion ==
Research and user experience came to following conclusion:

=== Pros ===
The advantages of this AlphaSlider approach are:
* there are no typing errors
* performance increases as the number of words per entry increases
* keyboards are not necessary
[Osada et al., 1993]
* due the small size of Alphasliders, they can be placed on small displays, like those of mobile devices.
* quick and easy usage, even for unexperienced users
* the alphanumerical distribution of the output can be seen with ease, because of the proportional output of pixels representing them on the alphaslider.

=== Cons ===
The disadvantages of the current implementation are that:
* the number of entries is limited by the number of pixels
* Alphasliders also does not allow users to input words freely
[Osada et al., 1993]

=== Future Direction ===
Important items to examine are:
* slider design when the number of entries exceeds the number of horizontal pixels
* performance when sliders and buttons are made of hardware devices
* combination of AlphaSliders and other information visualization techniquges
[Osada et al., 1993]
* With good use of feedback techniques, the Alphaslider is a powerful, compact, and rapid way of selecting items from lists.

Whereas a traditional slide area lets users page through the content of a scrolling list, the Alphaslider slide area lets users move directly to a certain part of the slider range by clicking in it.|[Ahlberg, Shneiderman, 1993] }}

{{Quotation|A Compact and Rapid Selector|[Ahlberg, Shneiderman, 1993]}}

== Usage ==
[[Image:Galphai.gif|thumb|200px|right|Alphaslider]]
The AlphaSlider interface was originally devised in 1993 and promoted by Ahlberg and Shneiderman. The essential components of the AlphaSlider are the same as that of the drop-down listbox. There is a slider area, a slider thumb (the square in the middle that a user can directly drag on), and left / right arrow.

The small size of the Alphaslider allows it to be placed on mobile devices, on a credit card, on a control panel for a VCR, or as a widget in [[direct manipulation|direct manipulation]] based database interface.
[Osada et al., 1993]

== Conclusion ==
Research and user experience came to following conclusion:

=== Pros ===
The advantages of this AlphaSlider approach are:
* there are no typing errors
* performance increases as the number of words per entry increases
* keyboards are not necessary
[Osada et al., 1993]
* due the small size of Alphasliders, they can be placed on small displays, like those of mobile devices.
* quick and easy usage, even for unexperienced users

=== Cons ===
The disadvantages of the current implementation are that:
* the number of entries is limited by the number of pixels
* Alphasliders also does not allow users to input words freely
[Osada et al., 1993]

=== Future Direction ===
Important items to examine are:
* slider design when the number of entries exceeds the number of horizontal pixels
* performance when sliders and buttons are made of hardware devices
* combination of AlphaSliders and other information visualization techniquges
[Osada et al., 1993]
* With good use of feedback techniques, the Alphaslider is a powerful, compact, and rapid way of selecting items from lists.

UE-InfoVis0607 0027217: /* Conclusion */

== Definition ==
{{definition|The Alphaslider is used to rapidly scan through and select from lists of alphanumeric data. The essential components of an Alphaslider are a slide area, a slider thumb, a text output and an index to the elements that the slider operates over. Whereas a traditional slide area lets users page through the content of a scrolling list, the Alphaslider slide area lets users move directly to a certain part of the slider range by clicking in it.}}
[Ahlberg, Shneiderman, 1993]

{{definition|The small size of the Alphaslider allows it to be placed on mobile devices, on a credit card, on a control panel for a VCR, or as a widget in [[direct manipulation|direct manipulation]] based database interface.}}
[Osada et al., 1993]

{{definition|A Compact and Rapid Selector}} [Ahlberg, Shneiderman, 1993]

== Function ==
The AlphaSlider interface was originally devised in 1993 and promoted by Ahlberg and Shneiderman. The essential components of the AlphaSlider are the same as that of the drop-down listbox. There is a slider area, a slider thumb (the square in the middle that a user can directly drag on), and left / right arrow keys. The function of it is identical to that of a drop-down listbox, except for its vertical orientation.

== Conclusion ==
Research and user experience came to following conclusion:

=== Pros ===
The advantages of this AlphaSlider approach are:
* there are no typing errors
* performance increases as the number of words per entry increases
* keyboards are not necessary
[Osada et al., 1993]
* due the small size of Alphasliders, they can be placed on small displays, like those of mobile devices.

=== Contra ===
The disadvantages of the current implementation are that:
* the number of entries is limited by the number of pixels
* Alphasliders also does not allow users to input words freely
[Osada et al., 1993]

=== Future Direction ===
Important items to examine are:
* slider design when the number of entries exceeds the number of horizontal pixels
* performance when sliders and buttons are made of hardware devices
* combination of AlphaSliders and other information visualization techniquges
