Slides for a short course I taught for UXPA DC on Feb 27, 2013. This is a UX 101- basics if you are new to UX and Usability. The focus is on desktop websites, but many of these principles apply to other products (e.g., surveys, apps) and devices (e.g., tablets, smartphones). Stay tuned for an updated version that is mobile-heavy.

Background Knowledge

•What does usability mean to you?

•Have you been involved in usability research?

•How is “user experience” different from “usability?”

@romanocog @forsmarshgroup

Usability vs. User Experience

•Usability: “the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use.” ISO 9241-11

•Usability.gov

•User Experience includes emotions and perceptions.

Measuring the UX ! !

Evaluation Tool

Questions Addressed: Do your users…

Advantages Disadvantages

 !

 ! ! ! ! ! !

Task Performance (e.g., accuracy, efficiency)

•  Navigate or use your product efficiently? •  Use your design as you intended? •  Find key items or content?

•  Objective measure of usability •  Provides multiple measures that are easy to collect •  Straightforward quantitative comparisons between different

designs or groups of users.

•  Does not reveal complete experience (e.g., few errors, but bad experience)

•  Does not inform the source or cause of the issue

•  Answers “what” but not “why.”

Subjective Reactions (e.g., satisfaction survey,

debriefing interview)

•  Verbalize a positive experience? •  Express frustration about functionality,

navigation, or content? •  Indicate that they will use your product again in

the future?

•  Insight into users’ thoughts •  Satisfaction surveys provide quantitative measure of subjective

experience •  Some insight into emotional responses •  Explicit intentions (e.g., on whether they will use product in

future).

•  Lack insight into user’s experience as they work with the interface (e.g., satisfaction measure at end)

•  Memory is fallible (debriefing and satisfaction measures at end)

•  Responses are biased by social desirability, overthinking, and uncertainty.

Moment-to-moment participant feedback

(e.g., think aloud, button presses, rating dial)

•  Indicate a positive experience in the moment? •  Run into problems at a specific point when

using your product? •  Get turned off at a specific moment?

•  Insight into users’ thoughts •  Real-time insight into participants explicit emotional reactions.

•  Responses are biased by social desirability, overthinking, and uncertainty

•  May interfere with normal task performance.

Eye Tracking (e.g., fixation quantity, fixation duration, pupil

dilation)

•  Visually scan your product as you intended? •  Get excited or frightened when looking at

specific components of your product? •  Notice your advertisements? •  See the content and features you want them to

see? •  Get engaged with your product? •  Run into problems after looking at a specific

component? •  Overwork their eyes and attention when using

your product?

•  Objective assessment about items that may be distracting, attracting, or confusing

•  Can assess visual search strategy and efficiency •  Objective assessment of or anxiety, which is difficult to describe

or people may not describe due to social desirability •  Assess mental workload (e.g., hand-eye movement) •  Modern non-invasive and non-obtrusive technology •  Implicit measure that is well understood and researched in UX .

•  Some participants eyes do not track well •  Somewhat expensive •  Longer analysis time.

Emotion Recognition (e.g., facial or audio)

•  Emotionally react to your product? •  Have the emotional reaction you intended from

using your product?

•  Real-time tracking of facial expressions and voice fluctuations •  Modern non-invasive and non-obtrusive technology.

•  Not well studied in UX research •  Somewhat expensive •  Longer analysis time.

ElectroDermal Activity (EDA)

•  Emotionally react to your product (how intense is that emotion)?

•  Have the emotional responses you intended? •  Engage with your product throughout its use?

•  Real-time measure of sympathetic nervous system through the skin

•  A measure of emotional intensity •  Correlated with stress, excitement, engagement, frustration,

anger •  Modern non-invasive and non-obtrusive technology

(conductance from wrist).

•  Moderately correlated with palm •  Not well studied in UX research •  Somewhat expensive •  Longer analysis time.

Neuroimaging (e.g., fMRI, EEG, fNIRs)

•  Respond in a way that will lead to behavior change?

•  Over or underwork attention and mental resources when using your product?

•  Engage with your product throughout its use?

•  Deeper understanding of what user is experiencing (e.g., fear, engagement, excitement)

•  Deeper understanding of engagement •  More temporally or spatially precise (varies among options).

•  Invasive and obtrusive technology (varies among options).

•  Need complex lab space •  Expensive •  Long set-up time •  Long analysis time.

Measuring the UX

•How does it work for the end user?

•What does the user expect?

•How does it make the user feel?

What People do on the Web

UX Design Failure

•Poor planning

•“It’s all about me.” (Redish: filing cabinets)

•Human cognitive limitations

•Memory & Perception

•(fun activity time)•Chunking

Memory

•Remembering is not a completely independent function, entirely distinct from perceiving, imaging, or even from constructive thinking, but it has intimate relations with them all…One’s memory of an event reflects a blend of information contained in specific traces encoded at the time it occurred, plus inferences based on knowledge, expectations, beliefs, and attitudes derived from other sources.

• Mental Models

Sir Frederick Bartlett (1886-1969), Remembering: A Study in Experimental and Social Psychology, 1932

Content

@romanocog @forsmarshgroup

Content Considerations

•Why do users come to your site?

•Define your purpose

•Objectives of the site

•The site’s purpose

•The user’s purpose, task, goals (personas)

•Content must meet both

• It’s not reading; it’s information sharing.@romanocog @forsmarshgroup

Content Considerations•Does it need to be there?

•Self evident

•Obvious

•Self explanatory

•Less is more

•Get rid of half the words on each page, then half of what’s left
