2. User Interface Design
User interface design is a combination of data
collected from user testing and research and
intuition.

3. UI Design =

- Part Intuition
Intuition is subconscious

4. Define: Intuitive
in·tu·i·tive
inˈt(y)ooitiv/
͞

without conscious reasoning; instinctive.

5. Define: Intuition
in·tu·i·tion
int(y)ooˈiSHən/
͞

6. Intuition Factors
Personal Instinct
- What seems right to me as a designer?
Experience Driven
- What has been successful in the past?
Learned Usability
- What has become a standard within the software user base.
Perceived Usability
- What do I think the user will do in this scenario?

7. Personal Instinct
Example: When creating events, a user will
want to select the type of event first.
Subconscious Reasoning: I think of the event
type first.

8. Experience Driven
Example: When selecting restaurants from a list,
the users want to have the ability select multiple
items.
Subconscious Reasoning: I have seen users
want this feature in the past product I have
designed.
Note: May be deduced from past user testing or research.

9. Learned Usability
Example: The button at the top right of a
screen advances the page forward.
Subconscious Reasoning: Users have known
the top right button to advance the page
forward in the past, and expect the new
software to do the same.

10. Perceived Usability
Example: Users will separate business accounts
from personal accounts in banking software.
Subconscious Reasoning: Users will expect the
same separation to be in place with new forms of
banking related software (excluding relation to core
competency of product).

11. Closing
Intuition Factors help designers achieve better
design.
Intuition paired with research will yield the best
results.
