how is your design evaluated?
by a panel of experts Q: how do you assess concepts or designs? A: Scott Jenson (former director of Symbian):
“First I’ll be asking ‘what’s the value of this?’, that is ‘Will people really want it?’ [… the] second is simplicity.” Jones & Marsden (2006)
“…being humble as these [designs] are
evaluated and seen to fall short, and to need refining.”
Jones & Marsden (2006)

topics addressed in this class
➝ design thinking ➝ interaction design ➝ user experience
![Page 15: PxS'12 - week 1 - Introduction](https://reader033.vdocuments.net/reader033/viewer/2022051512/54461bdfb1af9f29098b4644/html5/thumbnails/15.jpg)
design brief
People’s physical and mental health are one of the most precious goods available to them. Mobile phones have become a large collection platform for sensor data either direct through e.g. GPS and accelerometer or indirectly by providing sensor data from other sources, which can be used to inform people’s decision making and daily life. Your task is to design an application that empowers people to leverage sensed data for their well-being in terms of either: - personal health, "- environmental health or "- social health.

what is design?
hard to grasp – industrial design, graphic design, software design, interface design, product design …
in interaction design (Fallman 2003) : ➝ scientific/eng. process (conservative) ➝ art form (romantic) ➝ ad-hoc activity (pragmatic, bricoleur) none are adequate – design is unfolding "both problem and solution evolve through sketching (prototyping)
![Page 22: PxS'12 - week 1 - Introduction](https://reader033.vdocuments.net/reader033/viewer/2022051512/54461bdfb1af9f29098b4644/html5/thumbnails/22.jpg)
why design?
➝ post WWII declining American manufacturing quality disillusioned purchasers who, after being attracted by external style, found products unsatisfactory in use
➝ American industry got decimated from 1960s on from imports from Japan and Germany where greater attention to production quality and a more holistic approach to design were the norm.
➝ key differentiator for products ➝ key skill in IT – differentiator for employees

why design digital products
➝ digital products’ shortcomings: ➝ require computer-centred thinking ➝ poor behaviour, rudeness
➝ reasons ➝ ignorance about users ➝ conflicting interests ➝ lack of process

sketchbook
➝ jot down and annotate ideas (no idea is bad) ➝ explore & refine ➝ develop variations, alternatives and details ➝ refer back, reflect ➝ record other good ideas you see ➝ collection material (pictures, screen shots), tape
them

what is interaction design (IxD)?
➝ it's about the design of behavior"http://designmind.frogdesign.com/blog/behaving-badly-in-vancouver.html
➝ designing the mechanisms for interacting with a product (Cooper 2007)
➝ …designing interactive products to support people in their everyday and working life (Preece et al, 2002)
![Page 27: PxS'12 - week 1 - Introduction](https://reader033.vdocuments.net/reader033/viewer/2022051512/54461bdfb1af9f29098b4644/html5/thumbnails/27.jpg)
interaction design within a company
➝ management ➝ marketing ➝ engineering ➝ design team How to achieve buy-in for your ideas? How do you
communicate your ideas to them? What’s the language – same as yours?
Scott Jenson: “Design is about semantics and syntax. First you need to see what people do and want – the semantics and then you have to find a way to make that possible – the syntax.”
![Page 28: PxS'12 - week 1 - Introduction](https://reader033.vdocuments.net/reader033/viewer/2022051512/54461bdfb1af9f29098b4644/html5/thumbnails/28.jpg)

design philosophy
➝ centred on human needs ➝ individual or group ➝ support goals and activities ➝ design technology to fit human needs and
characteristics ➝ involve users whenever possible ➝ mix analytical, creative and pragmatic approaches ➝ pick from range of design tools ➝ use existing best practices but not uncritically ➝ monitor design process and reflect on it
![Page 30: PxS'12 - week 1 - Introduction](https://reader033.vdocuments.net/reader033/viewer/2022051512/54461bdfb1af9f29098b4644/html5/thumbnails/30.jpg)
what is UX?
“User experience encompasses all aspects of the end-user's interaction with the company, its services, and its products. The first requirement for an exemplary user experience is to meet the exact needs of the customer, without fuss or bother. Next comes simplicity and elegance that produce products that are a joy to own, a joy to use. True user experience goes far beyond giving customers what they say they want, or providing checklist features. In order to achieve high-quality user experience in a company's offerings there must be a seamless merging of the services of multiple disciplines, including engineering, marketing, graphical and industrial design, and interface design.”
Nielsen, Norman Group

user-centred
“User experience and interface design in the context of creating software represents an approach that puts the user, rather than the system, at the center of the process. This philosophy, called user-centered design, incorporates user concerns and advocacy from the beginning of the design process and dictates the needs of the user should be foremost in any design decisions.”

product centred
“The user experience for Mac OS X applications encompasses the visual appearance, interactive behavior, and assistive capabilities of software. With the Aqua graphical user interface, Universal Access features, and user-assistive technologies like the Address Book framework, Apple Help, and VoiceOver, you can deliver the cohesive and professional user experience that Macintosh users have come to expect. It's easy to leverage the user experience technologies of Mac OS X to make great Macintosh software.”

bad UX
➝ “Technology that does not work the way they expect makes people feel stupid.”
➝ “if you intend to drive people away from your site, it’s hard to imagine a more effective approach than making them feel stupid.”

➝ User: “… so I have all these files and documents, all over my desktop, different versions of documents in different folders, and documents I don’t need any more. I never get round to tidying up. I keep emails because I might need because of the address, or the content. But I never get round to putting them into the address book and deleting the mails, so they just pile up. My electronic workspace is a mess.”
➝ Q: How does that make you feel? ➝ User: [thinks] “It makes me feel that I am a bad person.”

➝ represent user groups ➝ system may be used by
one or several personas ➝ different characteristics ➝ different goals
➝ e.g. buyers of a new car ➝ Jean-David (playboy): "
go fast, impress women ➝ Aurelie (soccer mum): "

➝ persona-based scenarios "concise narrative description of how persona interacts with system to achieve goals
➝ context-based scenarios "how product can serve needs of persona, created before any design is done
➝ to key path scenarios – refined with design ➝ to validation scenarios – based on ❛what … if❜"
focus on illustrate requirements (the what), "top-down decomposition to functionality (the how)
scenarios

❝… scenarios are an interactive means of defining the behaviour of a product from the standpoint of specific users (personas). This includes not only the functionality of the system, but the priority of functions and the way those functions are expressed in terms of what the user sees and how she interacts with the system. use cases, on the other hand, are based on exhaustive descriptions of the functional requirements of the system, often of a transactional nature, focussing on low-level user actions and accompanying system response.❞

brainstorming
➝ group size <10 – ideally between 5-7 + facilitator ➝ find and set up comfortable space ➝ appoint recorder - up-coming ideas on shared
display, flip chart, whiteboard ➝ ice-breaking exercise – to familiarize members of
groups ➝ define problem clearly ➝ goal: generate as many ideas as possible

brainstorming – how to
➝ address what, how, when, where and why ➝ give people time on their own (5 minutes silence)
at beginning then ask to share them ➝ encourage ➝ to develop ideas of others further or use as new seeds ➝ enthusiastic, fun, criticism OK
➝ include everyone to contribute (practical and impractical ideas) and develop

ice breaker
➝ effective to start a training, team-building event ➝ goal: ➝ get to know each other ➝ get into the event ➝ become comfortable contributing to event ➝ establish level playing field ➝ create common sense of purpose
➝ ingredients: ice, a breaker (method), a facilitator

or goal ➝ are unfamiliar with topic at hand ➝ don’t know the facilitator but should and vice
versa

the ice
participants have ➝ not met before ➝ different age, status or levels in an organization ➝ different backgrounds – different perceptions of each
