Week 6: Business Reporting, Visual Analytics & Dashboards (Part 2) Chapter 2
Performance Dashboards
Dashboards provide visual displays of important information that is consolidated and arranged on a single screen so that information can be digested at a single glance and easily drilled in and further explored.
Visual Perception in Pre-attentive Processing
- 4 categories (pre-attentive attributes)
- Color
- Form
- Position
- Motion
-
-
- Motion
- Flicker (A visual attribute of an object, such as color, continuously changes back and forth between two values, or the entire object it-self repeatedly appears and then disappears.)
- Form
- Orientation
- Line length
- Line width
- Size
- Shape
- Added marks
- Enclosure
Gestalt Principles
- The Gestalt approach focused on looking at things as a whole, suggesting that the whole was more than simply the sum of its parts.
- 6 Principles for grouping, separating, emphasizing data:
- Principle of Proximity
- Principle of Closure
- Principle of Similarity
- Principle of Continuity
- Principle of Enclosure
- Principle of Connection
Principle of Connection
- States that we perceive objects that are connected in some way as belonging to the same group. Grouping produced by connection is stronger than that produced by proximity or similarity (colour, size and shape)
Principle of Proximity: states that we perceive objectives that are located near one another as belonging to the same group.
Principle of Similarity: states that we perceive objects share some visual attribute as belonging to the same group.
- Humans tends to group objects that are similar in: colour, size, shape, orientation
Principle of Enclosure: states that the objects that are enclosed by a visible border are perceived as belonging together
Principle of Closure: asserts that humans perceive open structures as closed, complete or regular when we can reasonably do so.
- Enclosure is not necessary and will create clutter.
Principle of Continuity: asserts that humans perceive objects as belonging together if they are aligned with one another.
- Principle is used to group data on a dashboard - distinct alignment is used for different departments within a division
