What is the scent of information?
human tendency to focus on relevant information and filter out all further information.
What is Recognition-based Scanning?
The memory process which involves the rapid spreading of attention to recognize familiar elements in a visual array in number of ways.
Why is recall a much more effortful memory process than recognition?
It requires conscious, cognitive exertion to actively remember where information is in the display. In order to save the user from having to recall data locations the most important, and regularly attended, information should stand out from the rest of the dashboard contents.

Von Restorff Effect.
Our ability to better remember or extract items that appear to stand out from the rest with greater immediacy.
What is Banner Blindness
A form of focussed visual attention where regular web visitors have learned that advertisements and other filler tend to be displayed along the top banner of a webpage.
In which of these cases should you use fragmentation?
a. You have to organize unrelated information
b. You have to show two or more sets of data/graphics
c. You have to organize related information
a. You have to organize unrelated information
Which of the following is good advice about using tabs in design?
a. You should abbreviate longer text labels to main consistency.
b. You should make tabs the same width
c. You should be as explicit as you need to, regardless of how wide the tab becomes.
c. You should be as explicit as you need to, regardless of how wide the tab becomes.
What can happen if you divide data into panels, tabs, etc. for users to access separately?
Users will find it harder to do comparative analysis
What should you do to avoid users needing to take further action to access information related to what the initial display shows?
Try to make the dashboard take up just one screen.
Descriptive text is a. qualitative b. quantitative
qualitative
statistics is a. qualitative b. quantitative
quantitative
A dashboard design should enable viewers to access all information from a ….
single, fixed screen
Why should a dashboard design enable viewers to access all information from a single, fixed screen.
Forcing the user to locate information through further operations or interactions adds unnecessary extra steps to the task of accessing all the relevant data represented within the dashboard. However, the sheer volume of raw data that must be shown in some visual form on the dashboard places great strain on the finite amount of screen space.
What is a major challenge that designers face when designing a dashboard?
How to fit everything into this fixed space without producing a cluttered display.
Overloading the viewer with statistics, visuals and any other type of information can affect their ability to quickly isolate relevent information from the busy display.
It is the role of the designer to ensure viewers can identify and extract the desired information as quickly and accurately as possible.
What can False visual hierarchies lead to?
It can lead the user to neglect important data sets or draw premature conclusions. Only institute visual hierarchies where there is a definite order of importance, otherwise new visitors may overlook important information and experienced users may be frustrated by the misleading design.
What should the designer cater to rather than arranging information in an arbitrary view of the how the dashboard SHOULD appear?
The design should be catered according to the type of user or viewer, arranging information to suit their intentions.
Although dashboard displays are at their best when all information can be reached from one fixed screen, the sheer amount of data contained within most dashboards places a great burden on this limited space. It is down to the designer to organize large amounts of information into a coherent body that enables immediate extraction of relevant data.
What does the ‘scent of information’ involve in a dashboard design?
That users seek out the most relevant information and neglect most (if not all other data)
Of the following, how might you best meet your users’ needs?
a. Include an adequate degree of separation between data sets
b. Include all data for users to find, even if they need to scroll
c. Include qualitative data on one side of the screen and quantitative data on the other.
a. Include an adequate degree of separation between data sets
What is Business Intelligence?
Ann interactive process for exploring and analyzing structured, domain-specific information.. to discern business trends or patterns, thereby deriving insights and drawing conclusions.
What are the four characteristics of the so-called “aha”! experience?
i) Suddenness, in that the experience is surprising and instantaneous
ii) Ease, meaning the solution is processed without difficulty
iii) positive effect, i.e. the experience is gratifying
vi) the feeling of being right i.e he/she experiencing insight is in no doubt their insight is correct and would withstand further investigation.
Reducing the “travel time” required to reach the desired information can support both ___________ and __, which in turn promotes the eureka moments underlying advancements in various fields of study.
Suddenness and Ease
How can dashboard design support comparative analysis and promote the “aha” experience associated with gaining insight?
According to Sperling (1960) how many visual items can we hold in short-term memory at one time?
