3. My lab: Advanced Cognitive Engineering Lab
Research in Driver Behaviors/Safety:
• Investigate driving performance and social-psychological motivators of risky driving behaviors (e.g., distraction,

10. Introduction to Interaction Design
August 29th 2022

11. Good and Poor Design
https://www.interaction-design.org/

12. Good and Poor Design
• Our goal as designer
▫ Develop interactive products that are USABLE
 “Designing interactive products to support they way people communicate and interact in
their everyday and working lives”
• Designing for the “user experience”
▫ Easy to learn
▫ Effective
▫ Enjoyable
• Designing an interactive product is not the same as engineering the software for it

14. Bad Designs
• https://cse.buffalo.edu/faculty/ahunt/classes/hci/badpage/splashpage.html

15. Important Considerations – What to design
• Need to consider:
▫ Who the users are (who is going to use the device)
▫ What activities are being carried out (what will they be doing)
▫ Where the interaction is taking place (when and where will they do it)
• Need to optimize the interactions users have with a product
▫ Should match the users’ activities and needs

16. Discipline of Interaction Design
• “Designing interactive products to support the way people communicate
and interact in their everyday and working lives”
- Preece, Sharp and Rogers (2015)
• “The design of spaces for human communication and interaction.”
- Winograd (1997)

17. Discipline of Interaction Design

18. Working in multidisciplinary teams
• Many people from different backgrounds involved
• Different perspectives and ways of seeing and talking about things
• Benefits
▫ Can generate more ideas and designs
• Disadvantages
▫ Difficult to communicate and move created designs forward

19. User Experience
• How a product behaves and is used by people in the real world
▫ The way people feel about it and their pleasure and satisfaction when using it, looking
at it, holding it, and opening or closing it
▫ “Every product that is used by someone has a user experience: newspapers, ketchup
bottles, reclining armchairs, cardigan sweaters.” (Garrett, 2010)
▫ “All aspects of the end-user's interaction with the company, its services, and its
products. (Nielsen and Norman, 2014)
• Cannot design a user experience, only design for a user experience

20. Interaction Design Process
• Establish requirements
▫ Identify needs and requirements for user experience
• Develop alternatives
▫ Develop alternative designs
• Prototyping
▫ Build interactive prototypes so characteristics can be communicated & assessed
• Evaluating
▫ Evaluation of design throughout the development process

21. Core characteristics of interaction design
• Users should be involved throughout the development of the project
• Specific usability and user experience goals need to be identified, clearly
documented and agreed to at the beginning of the project
• Iteration is needed

22. Why do we do all of this?
• To help designers
▫ understand how to design interactive products that fit with what people want, need
and may desire
▫ appreciate that one size does not fit all
e.g., teenagers are very different than grown-ups
▫ identify any incorrect assumptions they may have about particular user groups
e.g., not all old people want or need big fonts
▫ be aware of both people’s sensitivities and their capabilities
We must recognize individual differences (age, gender, experience, culture),
but also need to make sure our assumptions are correct.

23. Usability vs. User experience goals
Usability Goals
• Effectiveness
• Efficiency
• Safety
• Utility
• Learnability
• Memorability
User Experience Goals
Desirable aspects
satisfying helpful fun
enjoyable motivating provocative
engaging challenging surprising
pleasurable enhancing sociability rewarding
exciting supporting creativity emotionally fulfilling
entertaining cognitively stimulating
Undesirable aspects
boring unpleasant
frustrating patronizing
making one feel guilty making one feel stupid
annoying cutesy
childish gimmicky

24. Usability vs. User experience goals
• How are they correlated?
▫ Aesthetics matter and can improve usability, but doesn’t overcome poor
usability
▫ Not all goals are always possible/relevant

25. Design Project
• UB Blackstone LaunchPad Program
▫ Introduction to the LaunchPad program and challenges (next class)
▫ Additional coaching available
▫ Panel of external reviewers to provide feedback
▫ Prizes to be won!
• Grad students: the Mobile Health Applications for Consumers Design Competition
▫ Showcase the application of human factors/ergonomics methods and design principles to the design of
a mobile health application for consumers (healthcare recipients) or their nonprofessional support
network (informal caregivers and community).
▫ Optional for undergraduates
• Project team
▫ 4 members per team
▫ Find team members with common interests/goals
▫ Diverse set of skills – app/web development, design background, engineering, arts & humanities,
industry experience, research …..

27. Design Project
Your first task: use Discussion Board to introduce yourself, pitch and refine
ideas, and form teams
• Initial Introductions/Idea Pitch (Due 08/30)
▫ Go ahead and respond to each other’s idea pitch!
▫ Will leave some time next class for you to meet/discuss in person
• Team Formation and Topic Proposal (Deliverable 1) is due Sept 11
▫ If you don’t have a team in time, we will assign you to a team but you will
receive 0 on this component
