1) What questions are they trying to answer? Knowing it will make the visualization more relevant, more efficient, and reduce the noises (unnecessary information that may distract the users).
2) What processes are they trying to gain insight into?
The processes users take to gain insights determine the use of charts, colors, symbols, tables, etc. We must consider very carefully about the different cognitive abilities that the audiences may have to process visual information in order to convey the messages by our visualizations.
3) What decisions are they responsible for? The level of decisions, …show more content…
Define and describe the three stages of Design Psychology
1) Low-level Property Extraction
It means a limited set of visual properties which are processed pre-attentively (without need for focusing attention). This stage is important in designing a better visualization in order to determine what can be perceived immediately and which properties are good discriminators to avoid misleading on the viewers. The processing in this stage always occurs very efficiently, regardless of whether we wish it to or not.
2) Pattern Perception
Design of visualizations needs to consider how perception of the users will be built based on certain patterns displayed. A similarity or differences in position (e.g. background-foreground and grouping) and size (larger, smaller) between graphical elements will create certain perceptions in viewers’ minds, thus, will affect viewers’ interpretations of the displayed information. For instance, larger graphical elements tend to be perceived as more important than smaller ones. This stage is influenced by the information from the previous stage, also by conscious thought to some …show more content…
Define the OODA Loop steps and describe in your own words why it’s important to business.
OODA Loop is a workflow composed of certain processes, which are Observe, Orient, Decide, and Act. It is often used to describe commercial operations and learning processes.
1) Observe
Observe means to compile and arrange the raw data from various sources such as previous experiences and real world occurrences on any formats such as reports, audio, or people interaction in the environment. In business, this process is very important to provide initial data that can be used to generate useful information on the next stage in order to make business decisions. This needs the ability of knowing which elements of information to monitor and how to apply the right filters to each.
2) Orient
Orient is the process of gathering the knowledge from the observed data to generate useful information. This phase determines what the data means to users and what the users can do about it. As the repository of previous knowledge and experiences in user’s mind, orient is the most important part of the OODA Loop since it shapes the way we observe, decide, and
