assignment 2 published on Canvas:
Your challenge is choose one existing AI-integrated interactive computer system or interface and run a user research study with 3–5 participants. You will answer the research question: “How do users’ mental model of the AI system align with the behaviour of the system and what usability issues arise from any misalignments?”
01 SUS i'd like to play beat the intro in a minute
02 LIA [ oh no: ]
03 SUS [ alexa ][ (1.1) ] beat the in[tro

Grounded Theory (GT) is an old and important qualitative analysis technique (Corbin & Strauss, 2014; Galser & Strauss, 1967)
framework | data | focus | outcomes | granularity |
---|---|---|---|---|
conversation analysis | spoken conversation recordings | process of conversations | how conversations are processed and progress | words or smaller |
discourse analysis | speech or writing | how words convey meaning | implicit or hidden meanings in text | word, phrase |
content analysis | written text, video, audio, images | how often something is featured or is spoken about | frequency of items in text | words to artefacts or people |
interaction analysis | video of activities | interactions between people and artefacts | how knowledge and action are used in an activity | artifact, dialogue, gesture |
grounded theory | empirical data of any kind | building theory from a phenomenon | theory grounded in data | varying levels |
systems-based frameworks | large-scale and heterogeneous data | large scale systems of people and technology | organisational insights | macro, organisational level |

)Specific interaction information can be represented in a formal/structured way when presented.
Context of use and examples of user experience can be seen as stories or narratives.
Overall advice about findings…
By this stage, you could be excused for being a bit confused about qualitative research in HCI.
This may feel firmly off topic, but we need to surface some friction about knowledge to properly explain the different approaches in qualitative research.
Does any of this make sense? What kind of knowledge would you want to deal with?
Discuss with someone near you for 2 minutes, then let’s hear some answers.
A code is: a name or label applied to a chunk of data
Let’s code some interview data.
David is explaining how orders groceries online.
Use the poll everywhere link to code statements and we will see them all together. We’ll code each statement for 1 minute and then discuss the results.
A theme:
“A theme captures something important about the data in relation to the research question, and represents some level of patterned response or meaning within the data set” (Braun and Clarke 2006, p.82)
How do we find them?
In this class:
Braun and Clarke insist that “themes do not emerge”, (Braun & Clarke, 2022)
Terry & Hayfield (2021) suggest approaching themeing by prototyping, an iterative process where “the goal isn’t to finish”.
Are your themes good? Test them.
There are different types of themes, and a common distinction:
Charles (2025; i.e., these slides!) suggests that 4 is a key heuristic for assessing theme thickness. (Disclaimer: may be revised in future!)
Number of words heuristic:
If your theme is <4 words, it might be a bit thin.
Number of themes heuristic:
If you are proposing >4 themes, they might be a bit thin.

Let’s cluster some codes from the HCI grocery interview.
This is fairly uncontrolled so be kind 😇
Cluster for 2-3 minutes, discuss, theme for 2-3 minutes, discuss.
A bingo card of potential researcher problems with (R)TA… which make sense so far?
B | I | N | G | O |
---|---|---|---|---|
Mentions inter-coder reliability | Implicitly (post-)positivist TA (not acknowledged) | More than 3 levels of themes | Mention of a lack of (statistical) generalisability | Messy mix of realism and constructionism |
Unacknowledged social cognitions (e.g., attitude or body image) | Themes are thin - just single idea (a code) | Themes do not have a central organising concept | “Themes emerged” | Data collection stopped at “saturation” |
Use of passive voice | No reflexivity | Thematic Analysis | Only Braun and Clarke 2006 cited | Mention of “bias” |
Clarke spelled as Clark (no e) | More than 6 themes | No theory of language-treated as a window to truth | Themes are topic summaries | Very few participants quoted / over-quoting of one or more |
Implicitly realist TA (not acknowledged) | Braun pronounced BRAWN (not Brown) | Mismatch between extracts and analytic claims | Use of a codebook | Data are just paraphrased without interpretation |
Burroway’s definition (Rode, 2011):
Let’s try it:
What is your 1-sentence statement of positionality as a researcher?
Use the poll everywhere link to provide it.
Who has a question?
