Making Tea with Chemists: Exploring Boundaries and Breaking
BooksA smarttea production
No chemists were hurt in the making of this presentationOfficial web site: www.smarttea.org
Designing a digital lab book
eScience context: rapid communication of and access to results in progress not just in pubs
Bottleneck: wet lab records are paper based - difficult to access/share
Goal: convert paper system into digtital one
Many Lab book Replacements have been tried.Many have failed or had limited take up
How would we succeed?
Initial Approach
Our own field studies - rapid ethnography, targeted interviews, observationsGood for Context of work/artefact use
Preliminary Artefact Overview
No dedicated location
Data vulnerability
Access limited
Privileged IP * rigts
Uniqueness
Communal worth/private work
Historical significance
Missing pieces
We understood the artefact’s role.We had a strong sense of the environmentWe had a picture of why some of the book’s affordances were appropriate (and why some were not)We did not know how the chemists really engaged with the artifact in the process of an experiment
Problem: we aren’t chemists
Designers do not need to be domain experts
Much to be said about not being an expert - not missing the obvious - ability to get limnal.
But this was too domain naïve
So…
As an experiment
We made tea
Why make tea: available approaches and problems in ucd
Observation of an Experiment - even rapidExpert and artefact walk throughsApprenticeship and PrototypingCultural ProbesTask AnalysisDeconstruction/Reconstruction
Other methods: assumption of Time and Expertise
Chemistry experiments can take days, weeks,
months, years.They require high
domain knowledge
They are fluid, loosely structured
things
Breaking the book: Decon/Recon
We wanted to design services to support the activities that took place in the lab - to leverage what is already done
Thus, we questioned whether the UI needed to mimic paper
we sought to create the affect of the paper experience
Hand written coshh form
Hand written lab book entries
What we needed
A way to extend decon/recon for non-expertsA way to compress timeA faithful, not overly simplified processA way to engage the process
A language we (chemists and designers) could all understand to interogate the process (the experiment)
Enter Analogy
Making Tea: design elicitation through analogy
Developed and validated the analogy with chemistsGave us a way to ask questions that would not otherwise have been possibleLet us maximize observationGave us repeatabilityDerived rudiments of a process model, tooProvided lingua franca with chemistsProvided a fun low risk environment that facilitated discussion among participants

Tea gave us a way to understand not only the process but the experience of the process for our design.
Sample Questions from Tea
Is that it? No really, that’s all you record?So, do you add the milk first, or the tea first?
Tea 1 Tea 2
Tea 2aTea 1a
Tea 1b
Positive experiences - affect to capture
Casualness of entry, pictures and notes
Low attention, but frequent focus
Minimal description of activities
High degree of multi-tasking (multiple experiments on the go, much flipping back and forth)
Readily accessible; “safe”
Integration with other methods
Task analysis of data entry interaction throughout experiment - caveats for loose variants - derived from mT
Lo-fi Prototype designs
Design review: We ran through our lo-fi prototypes with chemists by running the tea experiment
They knew what was going on and could comment on veracity, features, process
Initial ideas were good but the prototypes were too intrigued - did not reflect/support practice
Design review was critical for reality checking; tea made that possible
Results
In real use, chemists were able to record their experimentsAfter about ten minutes of use, they forgot about it as a new thing, and just used itMaking tea worked
“I can go anywhere and its, like,this is me and my data. It’s all there! Bang!”

(alan, these are notes for you)
It’s not about the bike book
We didn’t set out to use a tablet
We wanted to try really breaking the book, distributing the parts across the lab - that’s how it’s designed.
All we could get was a tablet - which looks like a book - sort of.
To paraphrase Lance Armstrong
Aside
Generalizing:Making Analogies
The analogy is key: it is developed within the expert and design community - common ground
A domain expert participates
Analogy foregrounds processes and interaction with artefacts
Facilitates expert elicitation and design translation
Conclusion
Making tea - design elicitation by analogyGave us
Time
Process
Interaction
Maximized ethnography and enabled task analysis AND story telling to communicate the issues to another domain (recently, semantic web/grid modelling)
