Recap: What is Research?
An implicit assumption: industry and other researchers all thought one way about a problem.
“No, let’s do it this way instead:” The researcher offered a new perspective that nobody had ever
considered or made feasible before. They proved out their idea as the better approach.

This is not like typical HCI classes. Your goal is not just to fashion an alignment between people and technology.
Your goal is to articulate and generate entirely new ideas about that relationship.

HCI Research Comes in Many Forms
● Ubiquitous computing● Social computing
● Tangibles
● Accessibility
● Design Tools
● Media and Creativity● Programming Tools
● Design for special populations (e.g., children)
● And more….

We often discuss HCI research as “systems” or “studies”
Systems: main contribution is a cool new technology, typically with lightweight evaluation
Studies: main contribution is some understanding of interactions or behavior, typically including a
controlled experiment

Ubiquitous Computing (UbiComp)
Main Idea: computers, everywhere
Example: UbiFit Garden
● We can place sensors in your phone, which
you have with you always
● Those sensors can help you track your
activity
● By displaying activity we can encourage people to exercise more
9Consolvo et al., 2008

Social Computing
Main Idea: creating, recreating, or studying social behavior through technology
Example: Soylent
● Use crowdsourcing to edit writing
● Online workers can find points of
improvement, fix those parts, and verify
those fixes
10Bernstein et al., 2010
![Page 11: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/11.jpg)
Tangibles
Main idea: people can interact with digital information in the physical world
Example: inFORM
● A grid of pegs that can independently move
to create a 2.5D display, aka Shape Displays
11Follmer et al., 2013
![Page 12: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/12.jpg)
Special Populations
Main Idea: unique user groups require unique technologies
Example: Coco’s Videos
● Preschoolers can self-regulate their
technology use
● Kids can self-select usage time, usage plan,
and post-use activity in advance; tool will remind them to stick to this plan
12Hiniker et al, 2018

Accessibility
Main Idea: make technology accessible for everyone
Example: Spatial Layouts for Visually Impaired
● Use tactile sheets to print spatial layouts for
web/graphic design
● Overlay these sheets on tablets to combine
tactile feedback with a self-voicing digital design tool
13Li et al., 2019
![Page 14: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/14.jpg)
Design Tools
Main Idea: use technology to make design easier
Example: Learning Visual Importance
● Create neural networks that predict the
relative importance of different elements in
visual content
● Can be used for automatic thumbnailing and
real-time design feedback
14Bylinskii et al., 2017
![Page 15: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/15.jpg)
Media and Creativity
Main Idea: technology can enhance creativity and lead to better creative tools
Example: Draco
● Rather than animate individual objects, use
motion controls to add coordinated motions
to collections of objects
15Kazi et al., 2014
![Page 16: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/16.jpg)
Programming Tools
Main Idea: new technologies can make programming easier to do or learn
Example: Designing they Whyline
● Debugging is an interrogative process
● Created a tool that allows users to ask
questions about WHY or WHY NOT certain
things are happening in their programs
16Ko & Myers, 2004
![Page 17: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/17.jpg)
Takeaway: HCI research is broad, and there are opportunities to
pursue projects that align with almost any interest

![Page 19: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/19.jpg)
Nice to meet you!
● Name● Why are you interested in research?
● Why are you interested in HCI?

![Page 20: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/20.jpg)
Section Expectations
20
![Page 21: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/21.jpg)
What you can expect from me
● I will arrive to section 5 minutes early and will stay up to 10 minutes late for any quick questions or eager discussions
● I will start section on time every week and I will end on time
● I WILL NOT know the answers to all of your questions. Such is research. I WILL work with you to
find the answers (or reasonable approximations thereof).
● I WANT feedback. Something is confusing, stressful, moving too fast, moving too slow? Tell me.
21
![Page 22: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/22.jpg)
What I expect from you
● Respect each other. Most sections will function like research group meetings. This mean you will share out your progress and get feedback from each other. For that to work you need to be
listening.
● Laptops closed, unless we are working on something that requires a laptop.
● This is a collaborative space and we are here to support each other. Research is not an
independent endeavor. Share ideas and encouragement, but also accept criticism as constructive.

What is IRB?
23
![Page 24: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/24.jpg)
What is the Institutional Review Board (IRB)
● A panel of faculty, students, other professionals, and community members● Federally mandated for any US institution that accepts Federal money to conduct Human Subjects
Research
● Ensures Human Subjects Research follows federal ethics regulations
○ Research: an investigation design to develop or contribute novel, generalizable knowledge
○ Human Subjects: individuals about whom a research obtains either a) data through interaction or
intervention with the individual or b) identifiable private information
○ Federal ethics regulations: outlined in The Belmont Report (think: respect for participants, “do no
harm”, and don’t be exploitative)

IRB and HCI
● HCI is a discipline of Computer Science that relies heavily on human subjects● We need to be sure to treat these human subjects ethically
● This means that HCI projects that include human subjects research must undergo IRB review

![Page 28: What is HCI Research?](https://reader031.vdocuments.site/reader031/viewer/2022012012/61da5945005d9166110163e2/html5/thumbnails/28.jpg)
Assignment 1: Paper Reading
● Pick a paper (from a provided list) and outline it (i.e., convert it from full paper form back into a high-level outline/overview explaining the argument)
● Each paper selected corresponds to a section project, so pick a paper that relates to the project
that intrigues you most
○ Note: you are not tying yourself to a project here. You are gaining background to inform your decision. We encourage you to skim other papers of interest; you just only need to turn in an outline
for one.

Algorithmic Transparency
We know: users mistrust online profiles they perceive to be auto-generated only when users
believed they saw a mixed set of human- and AI-
generated profiles
We want to find out: how indicators of
algorithmic confidence, like quantitative
percentages or qualitative text descriptions (e.g., very confident), might affect user trust
Starter paper: AI-Mediated Communication:
How the Perception that Profile Text was
Written by AI Affects Trustworthiness

Automatic Content Warnings for Sensitive Posts
We know: • users rely on online content creators to post
trigger warnings about distressing content
• browser extensions can control what
content users see on the web (e.g., to
control procrastination)
We want to find out: if we can automatically generate online trigger warnings for distressing
content
Starter paper: Rotating Online Behavior
Change Interventions Increases Effectiveness
But Also Increases Attrition31Kovacs et al., 2018

Belonging and Bias in Web Interfaces
We know: that gender biases can be triggered by web design
We want to find out: how colorfulness,
complexity, imagery, and/or language
independently affect bias and belonging in web
interfaces
Starter paper: Gender-Inclusive Design: Sense
of Belonging and Bias in Web Interfaces

Learning Effects of In-Video Reflection Prompting
We know: in-video reflection prompts can help increase attention during educational videos
We want to find out: if these same prompts
affect learning outcomes as well
Starter paper: Understanding the Effect of In-
Video Prompting on Learners and Instructors
33Shin et al., 2018

Effect of Statuses, Typing Indicators, and Read Receipts on Digital Communication
We know: people express and detect emotions in text communication using four in-message
cues
We want to find out: how online message
“metadata” (e.g., status, typing indicators, read
receipts) affects digital communication and
meaning
Starter paper: Expressing Emotion in Text-
based Communication
