Ethics and TCPS
Ethical Conduct for Research Involving Humans (Tri-Council Policy Statement)
01
Scope of the TCPS
All research involving humans conducted under the auspices of institutions eligible for funding by one or more of the agencies.
Why?
“To promote high ethical standards of conduct in research involving humans through the development, evolution, interpretation, and implementation of the TCPS”
What is NOT covered?
Three Core Principles
Respect for persons
Autonomy, judgment, consent, trust, decision making.
Justice
Fair, equal, respect, concern. Vulnerability, recruitment, abuse prevention.
Concern for welfare
Physical, mental, spiritual, economic, social. Privacy, risk prevention, stigma.
Content
Ethics Use Case
Problem
Efforts towards automating knowledge assessment tasks using AI are biased towards underperformed schools.
Importance
Performance in National exams are important to define the educational future of teenagers in the UK.
TCPS2
Module 5: Fairness and equity. AI biased towards certain schools.
Overcoming
-Removing the AI agent for this task
-Re-training the agent with a different database.
Ethics Rubric
Submit the youtube link of your video and TCPS2 PDF certificate to LEARN before July 6, 9am (individually).
Usability Testing
Testing how easy a design is to use with a group of representative users
02
Today’s Lecture
Usability Testing
Inclusive design
Definition
Usability assessment is the approach that is used to ensure that a product, system or service is useful.
Early and continuous focus on users
Integrate considerations of all aspects of usability
Test and iterate continuously with users
User Research Methods
Usability Assessment Methods
Many of the methods were used in design and human factors work long before the notion of usability emerged as a practice
Usability Assessment Methods
A test subject is shown an aspect of product on paper (e.g., paper prototype) and is asked questions about how to operate it based on task requirement.
Usability Assessment Methods
Paper prototypes can be used to conduct usability testing of any type of user interface
5+
Real Users
5 users should be able to identify about 85% of all usability problems
Facilitators
Usability professional that record issues raised during the meeting. Act as a mediator.
1
Human-Computer
Typically the lead developer manipulates the paper prototype so that it can provide the feedback based on the user’s interaction
1
Observers
Their role to observe and interpret the users’ interactions with the paper prototype.
2+
Usability Assessment Methods
2. Alpha and beta tests
Early release of a product to a small group of users. The purpose for alpha and beta tests is to detect difficulties just before the release of a product.
Usability Assessment Methods
There is no one way to start a beta program, but here some ideas to start with:
2. Alpha and beta tests
Define the goals and rules of the beta testing
Why
Create a recruitment strategy
How
Invite People and keep them engaged
Whom
Beta test, observe and record
Do
Receive feedback and be critic
What’s wrong
Iterate the cycle until “good enough”
Improve
Usability Assessment Methods
3. Usability test
Informal series of studies performed early, midway through and at the final stages of development to discover product problems or opportunities for product improvements or new concepts
Usability Assessment Methods
3. Usability test
Users
Materials
Tools
Inclusive Design
Methodologies to create products that understand and enable people of all backgrounds and abilities
03
Inclusive Design
Describe inclusive design in 3 words
Designing with Accessibility in Mind
What does it mean to design inclusive and accessible experiences?
People with visual disabilities and braille displays
People with auditory disabilities and captions
People with motor disabilities and speech-to-text
Easily used or accessed by people with disabilities: adapted for use by people with disabilities.
Areas of Focus
Persona Spectrum
Inclusive Design Research
Disability: mismatch interaction between the features of a person’s body and the features of the environment in which they live (WHO).
