Product Design DelftX

My course notes for Product Design DelftX #delftxdesign designed and delivered by Industrial Design Engineering of the Delft University of Technology (TU Delft)
(recommended book, the Delft Design Guide)
Faculty
Jaap Daalhuizen (design thinking), Paul Hekkert (form theory), Pieter Jan Stappers (techniques), Jelle Zijlstra (didactics), Matthijs va Dijk (applied), Carlos Cardoso (fixation), Stefan va de Geer (concept dev and eval), Koos Eissen (sketching), Jan Buijs (creativity), Annemiek van Boeijen (culture), and student tutors Koen and Iris.

Course Notes:

The Delft approach to design consists of 6 steps occurring throughout a 'design cycle': Discover, Define, Design, Deliver; and that design is always iterative.
Annemiek van Boeijen clarifies that this should not be understood as some kind of mechanical loop. The process is in fact often chaotic, with ideas diverging and converging at different times. Iterative implies that we expect activities to repeat, that stages may occur in different sequences, that activities and phases may even overlap. 

The Delft Design Guide asserts that:
Products are just a means for accomplishing appropriate actions, interactions and relationships; products provide meaning for people only through interaction. (Buijs, 2012, p27)
In essence, products and services don't exist for their own benefit, they are tools through which people achieve their goals by interacting with the products.

A designerly orientation to the world is a kind of continuing questioning. Paul Hekkert refers to a way of 'seeing' the world as a way of noticing how products are used and the contexts from which they were developed. A shorthand for this approach is "why, how, what".

When analysing an existing product we ask 'why' it is the way it is, how it came to be. This is called the context level. Addressing these questions requires an understanding of the product's context and history. This is is an analytical process we call 'deconstruction', a kind of 'unpacking' the understandings, assumptions (implicit, explicit), conditions etc. that aligned to bring the original product into existence. Similar factors in turn precondition the bringing into existence of a new product.

When using a product we become involved in the 'how', the doing of using it. This is the 'interaction' level of analysis. The 'why' informs 'how' the product works, how it is used, how the work it does is achieved. The third analysis is 'what', that is the intention users have in using the product, what goals they achieve through using it. They refer to this as the product level, typically driving the development of a new product.

Overlapping with these questioning stances is an experiential orientation towards action which is an essential part of being a designer. Designerly action is stimulated by a feeling of 'urgency to act'. The urgency to act is aroused when "we reason from WHY, via HOW, to WHAT. The designer's action is to create the 'what'."  (Paul Hekkert, original emphasis)

The 'Design Squiggle' by Damian Newman. 

Evocative. http://ow.ly/SQGj4

My own design process sketch tries to bring something of the recursive/chaotic character of design, but not random, conveying that design is most definitely deliberate action, although a journey where the destination is not yet known.
One of my visualisations of the design process
By way of explanation: I adopt an orthogonal depiction in which direction changes convey design 'pivots', rather like the business term, where the objective shifts tangentially. The little boxes are intended to convey growing competence or knowledge of a particular area. The 'microcosm box' is a miniature of the larger diagram, intended to suggest the recursive nature of iterations with no real beginning or end as such.

The diagram is oriented in the overall shape of a backwards C in opposition to characteristic left to right progression characterising depictions of temporality that dominate the contemporary culture (a Western tradition?). I think it is important too to acknowledge the 'negative space' left by the contained and directed elements of the diagram. You may think of the negative space as 'the unknown'. I can read a similar interpretation in the negative space left by Newman's 'Design Squiggle' too.

Framing Devices

Delft employ framing devices to establish individual practices and orientation that may be called the 'design attitude', e.g. from objects (describing) what, how, why = deconstruction -> design process or 'designing' = future context, interaction, new object. Technology push, market pull, user centred.

Jaap Daalhuizen states that for a designer from Delft "designing is a verb first and a noun second". The gerund form of design and many of the other activities of design indicates that the process, creative problem solving, is a basic philosophy behind their approach. It involves, at different points, keeping control, releasing (losing) control, periods of sustaining certainty and then other periods where uncertainty is valued and emphasised. There are examples of oscillations between opposing conditions, what we might characterise as different kinds of tight-loose attitudes.

Paul Hekkert emphasises the fact that everything around us is designed, our houses, our environments, the cities we live in, the things we use. Whether these products, objects and things are designed well or not is another question, regardless they have been designed at some level, and furthermore we all experience and interpret the things.
We can consider the characteristics of extant objects at three distinct levels: what, how, why.
The 'what' level is concerned with so called objective aspects, for example the factual characteristics.
The 'how' level deals with explanation, our own mental models and design models, the mechanics of how objects respond to/in use. This involves an initial kind of unpacking of the object, a deconstruction of it (ideationally) and positing interpretations of how things happen.
The 'why' level is the level of broader context, understanding reasons why things are the way they are, what makes things meaningful).
All together these levels are an approach to design deconstruction, deconstruction of the designed object. This is simply a technique for interpreting, one of the approaches or tools of a 'design attitude'. We use this to consciously unpack experience. It is necessary because we don't always confront designs in a direct manner. However, through introspection and deconstruction we learn to identify, describe and unpack the ways that we feel and think about designed things. It is an analytical approach to gaining understanding of why things are the way they are.
The 'design process' is presented in symmetry with deconstruction. A design orientation involves a process built on knowledge established through deconstruction of extant objects. The design process is action as a mirror to design deconstruction.
In describing how deconstruction shifts naturally to designing Hekkert describes a designery feeling of "a sense of urgency", a desire to act, to change something, to alter the scene in order to learn or to improve the experience of using or interaction with these objects. The design process, design action, quickly becomes complicated because so many relevant factors must be brought into to play, to to understand, to explain, to justify, to use, to change, to act, to adapt etc. Designers inevitably respond to and draw upon factors from multiple domains; technology push, market pull, user centred needs. Each domain is comprised of and utilises many different factors. The designer's job is to focus on what is relevant and interesting. This job is, in part, an artful selective use of these factors and tools, used in order to obtain greater understanding, evidence, to test, to reason and appreciate the effect and affect of new designs.

The Morning Rituals Project

Over the course we develop an overall design project addressing the theme 'morning rituals'.
My notes on 'morning rituals'
My own morning ritual
The alarm goes off, throw off the covers, bathroom, brush teeth and shave, warm-up routine, make the bed, make sure the kids are awake and getting ready, get dressed, breakfast, go to work.
Open the office, start the computer, check email, respond, start work tasks. Get a cup of tea and complete more work tasks.
On the physiology of sleep/wake cycles
Our bodies respond to the transition from dark to light, the dawning of the day. No matter what time we go to sleep our bodies respond to the morning. Light stimulates cells in our retinas that in turn stimulating our brain and establish the circadian rhythm. The circadian rhythm is an endogenous cycle of biological activity synchronised with the day/night cycle. The retinohypothamic (RHT) tract is a photic (in relation to light) neural pathway that carries these light=day/dark=night signals to the suprachiasmatic nucleus (SCN) region of the brain. The SCN in turn plays a role in regulating our sleep/awake cycles. As it turns dark outside the RHT signals the SCN which then triggers the pineal gland (PG) to release melatonin, a hormone that prepares us for sleep. Waking up reverses this process. Interestingly the colour composition of the light matters; daylight equivalent is best at triggering melatonin release. In response to the issue of bright LED lighting ruining people's sleep cycles (link) night shift mode on iPhone changes the colour balance of the screen from bright blue/white to a softer yellow/white illumination (link).

Notes on a product for morning rituals

Improve on the LED Pillow Clock or a pillow that lights up?
Why not combine a pillow light with a sleep cycle stage sensor?

Associations
transitions, still tired, restarting
For the purpose of the exercise the morning rituals will be considered to occur over any part or all of the time from waking up to arriving at your next location (work, school). The designer's goal is to have an impact (positive) on the zone of interest, where the design is employed. The impact of the design should be valuable and meaningful for/to its users.

Discussions with others
I found the discussion posts to be really informative, more than just the usual, people are genuinely different, different habits, different rituals, different approaches. So many people do things just plain differently to each other, so much variation in approaches, in what people do, when and where they do it. Different priorities, sequences, orders. Different objects and arrangements.

Contesting the shape of technology

Terra incognita is a term derived from cartography and designates undiscovered lands; lands that are unknown, unmapped and, by implication, unowned.
It is closely associated with global expansions of the European colonial era, when explorers mapped the "unknown", then (usually) claiming the lands on behalf of their sovereign.
Through military conquest or legal fiat, the terra incognita segues into terra nullius ("nobody's land") or as military prize, to become the domain of a Crown or State.
The same process also corresponds to the domination, subjugation and alienation of indigenous peoples, through conquest or the law.

How might these consequential topics, linked with the great voyages of 'discovery', cartography, and conquest relate to contemporary high-tech design initiatives?

The concept of a terra incognita can be applied to technological feature topologies.
In this sense the terra incognita hints at the design and features of an emerging technology are as yet undetermined, unknown, or open to negotiation.


By considering an emerging technology to be a malleable resource, as a "terra incognita", diverse actors will engage in technological land-grabs in order to take ownership or control of the future shape of that technology.
Systems and technology designs are a kind of property, and the technology for public services is a kind of public property.
Contests for control and power take place for project resources but more significantly for the potentially preferable, desirable, lucrative or advantageous directions that design decisions may lead to.

Ownership or control of the features of a future technology is important because technology can become a "resource for", an instrument or system yielding power, money, influence etc.

And so it turns out that contests to control the shape of emerging technology are actually contests for the opportunity, if not the right, to shape social institutions.

Efficient way to anonymise interviewee identities for academic research

The question was discussed on tex.stackexchange.com

I'm looking for an efficient way to anonymise interviewee identities using a pseudonym list.
Case studies often use direct quotation from interviews and observational data.
In these cases it is usual to identify the speakers using a pseudonym and/or role label.
Anonymisation attempts to preserve the privacy of research subjects, following the 'do no harm' principle of social and human sciences research ethics.
Using a pseudonym preserves source attribution (i.e. justifies that the quote is an example of actual empirical evidence).

I expect that this requirement is a bit like creating a glossary, a register of names or list keywords used in a document (i.e. create-a-register-of-persons-with-biblatex or create-a-register-of-persons-with-references)

I imagine writing the quotes with correct attribution in my latex document, and they will be replaced when typesetting.
Something like \person{joe} and \personrole{ceo} and a catalogue command like \dramatispersonae that produces a register of the pseudonyms and their roles in a section, somewhat like a glossary, or characters of a play, the dramatis personae.

Perhaps I could do this with bibtex, but I need to the dramatis personae to be separate from the bibliography.

Notes:
I'm not referring to approaches for censoring, redacting or 'blinding' text (i.e. efficient-ways-to-anonymize-a-document)

Nvivo at UCD

The software is available to members of the institution through virtualisation servers.
The old approach was via Citrix client (for both Windows and OS X users) "link"
The new approach is via Application Jukebox client (only Windows users) "link"
Both require a UCD Connect userid and password to use.
Both suffer from latency delay issues so don't expect a snappy response, wait a while and the application should run ok (sooner or later).

Fonts on Mac

Use Font Book to install, view and manage fonts.
Located in the applications folder.
Open Font Book, or double-click a font file.

Q: How to make a MS Word document look like it has been typeset in LaTeX?


Mac Instructions only Based on James Lingard's MS Word template page.
Lingard's template file (LaTeX.dot) can be used to produce documents that look a lot like they've been typeset in TeX/LaTeX but you'll need to install the Computer Modern TrueType versions of fonts used by LaTeX to make them available in MS Word.

Installing the fonts:
  1. Download the minimum set: cmr10.ttf, cmbx12.ttf and cmbx10.ttf and other suggested tt files (e.g. bakoma true type fonts) Other examples: https://guides.lib.jmu.edu/freemedia/font and  https://www.1001fonts.com/ and more... 
  2. Once downloaded on the Mac, go to the download location and open the files by double-clicking. This starts Font Book which opens the tt (TrueType) font file. Font Book is included with OS/X. Basic instructions on using Font Book from Apple.
  3. Font Book provides a small display of the font and gives an option to "Install Font" via the button at bottom right of the window. 
  4. Click Install Font; Font Book then checks/validates the font. You might need to review warnings, all trivial as far as I make it, after which the font is now available for Mac applications to use. 
  5. The next time you open MS Word it will spend 30s or so updating its font listing. 
User installed fonts view in Font Book
Installing the Template:
Mac instructions only: You add Lindgard's LaTeX.dot file to the appropriate templates folder:
MS Word template location. From the Finder menu; Finder>Go>Go to Folder...
~/Library/Application Support/Microsoft/Office/User Templates/My Templates
Then create a new MS Word document based on the template via:
  1. From the MS Word menu bar: File > New from Template... 
  2. The MS Word "Document Gallery" window opens... 
  3. Select "My Templates" in the navigation pane... 
  4. Select the template named "LaTeX" 
Word Document Gallery: New from Template. Chose LaTeX

Your new document is now using Lindgard's stylesheet in MS Word, which should also be using the bakoma TrueType fonts. The screen and output should now mimic a LaTeX typeset document very closely.

Chemical reactions in Tex

Test that you have the packages loaded; from the command prompt enter

texdoc chemmacros
...to open The Chemmacros Bundle guide "chemforumla_en.pdf", inspired and based on usefully extending mhchem. 

My example...
\documentclass{article}
\usepackage{chammacros}
\begin{document}
\ch{Na2SO4 ->[ H2O ] Na+ + SO4^2-}\\
\ch{( 2 Na+ ,SO4^2- ) + (Ba^2+ , 2 Cl- ) -> BaSO4 v + 2 NaCl}\\
\ch{2 CaCO3 <=>[ H2O ] 2 Ca^2+ + 2 CO3^2-}\\
\ch{HCOOH + H2O <=>[ H2O ] H3O^+ + HCOO^-}\\
\ch{2 CO3^2-\ + 4H^+ <=> 2 CO2 + 2 H2O} \\
\end{document}

Nvivo Exercises

Notes after attending Ben Meehan's "Nvivo; Analysing your Data" course

  • Create Phase folders in the Nodes area to capture the state of the codes at different phases.
  • From initial readings develop an initial coding framework. 
  • Add the initial coding framework, i.e. add 'nodes' you anticipate using to code your data.
  • Gather your Interviews or transcripts in word. Formatting may be used for later auto-coding ('noding'). Applying Header 1 for several standard structured questions (closed or open), and can also apply Header 1 for the completely open ended unstructured lines of questioning. Could also use Header 1 for categorical data, structural data, attributes (e.g. male, female, rural, urban, highest qualification, age range).
  • Internal Sources. Add your transcripts, interviews and other data sources as separate files (word documents), ie. imported as internal documents. Organise them into separate folders or not. Folder structure might mimic the structure you've used in a file system. 
  • Alternatively you can include them as External Sources. The problem with external sources is that you lose the in-system coding and analysis capability. In this case the actual external source isn't accessible, rather the file/object you add to your Nvivo project is what is used for coding. So you'll need to add your own description or copy/paste some of the data in order to enable node coding and query/search etc.
  • Refine and develop the nodes/codes after each phase of coding.
  • Annotations are a bit hard to dig out but they are 'findable' via the query. Recommend using a keyword at the beginning of each annotation so that you can retrieve them all quickly. This is particularly handy if you use annotations as a place for developing ideas and your own writing.
  • Memos are a kind of 'next step' beyond 'annotations' for your own writing. Memos are handy in terms of being part of the Nvivo interface, they can be organised, subsetted and otherwise subject to global query/search coding/noding etc.
  • Memos are for secondary materials that you develop yourself. I use them as the starting point for my written analysis.
  • Classifications are a mechanism for associating categorical data, usually categories from tabulations (see above). A classification would match categorical/quantitative values with associated interview/observation or otherwise less structured matching data; done via a matching key as unique data index.
  • Query/search is a mechanism for more mechanical questioning of your data. Sifting motivated by defined questioning that can be expressed in terms of more and more complex search queries. Can use boolean and search logic to build up queries. Query/searches can be saved. Results of query/search can also be saved as 'coded' nodes, or as 'Collection' sets. 
  • Collection sets are more static versions or results from the data. They aren't usually incorporated into future query/search or dynamic node logic.
Magic step: interview files with same name as index in categorical excel 'table' can be automatically 'joined'.
