Questions?


Discussion Questions - Ben 1. Is it allowed for a design team to make up their own Heuristics? If so

what are the benefits? Draw backs? (In other words ask users to look for specific issues that they anticipate or recognize)

2. When following a heuristic, people can say if it breaks it. When is the best time to ask them for advice on how to make it better, inline or at the end?

3. What other applications see such a drastic law of diminishing returns (after 5 people...) it seems like a pretty logarithmic decline.

4. How do you handle disagreements between evaluators? 5. Nielson indicates that a good evaluator – someone who easily

identifies user issues – is just as likely to find a hard to find “hard to find” issues as a “poor” evaluator, why do you think this is?


Discussion Questions - Ben 6. Of the 10 Heuristics listed by Nielsen what do you think major

companies do the least, why? 7. As an engineer the notion that performing the same experiment twice

and not drawing the same conclusion being a good thing (according to Forlizzzi) is difficult to swallow. Do you agree that a good HCI study should concentrate on relevance rather that validity?

8. Where do you think a traditional designer is more useful in HCI in the front end development or back end usage?

9. When performing a Heuristic evaluation how do you focus a participant away from creeping featurism and toward the design as it is. Especially in the hi fidelity proto-type stage.

10. Is it better to ask your users to categorize their comments according to Nielsons severity ratings, or based on your interpretation of the extent of the issue they highlighted to bin them yourself (as the designer)?


Discussion Question - Sarah Nielsen provides severity ratings for usability problems. Often

these are subjective based on the evaluator. Nielsen recommends using multiple evaluators to avoid this. Can you think of a way to make this less subjective?

Are there any gaps in the model provided by Forlizzi et al? Nielsen provides the ten usability heuristics. These were

developed before touch screens. Can you think of any guidelines that need to be added in order to effectively evaluate technology on touch screens?

According to Forlizzi et al. interaction design research in HCI is changing. How will this affect the field of HCI?


DESIGN SPECS (P5)


Design Specifications

Give enough detail about the design for engineers to be able to build it

Describe and justify major design decisions Convince the reader of the merit of each decision

Include any limitations – in the actual design or its scope Anticipate questions about your design

No standard format or content P5 requirements are based on good practice


1. Who the intended audience for the document is Know your audience Who is your audience?

For P5: engineers Who else might be your audience?


2. A clear description of the design problem Present the design problem and make the goals of

your design really clear Think about:

The language/writing style How you breaks the problem down How you introduces your key points


3. A clear description of the project scope.

What do we mean by “project scope”? What do we mean by “what parts of the design are

left unspecified”? A lot of things will be outside the scope of your

project. What's worth mentioning?


3. A clear description of the project scope

Determine your project scope What's in the scope, what's been left unspecified

For each group: What is the scope of your project (in one sentence)? What’s one example of something that's outside the scope

of your project?


4. Details about every major design decision within your project scope Step 1: make a list of the major design decisions

Example: why did we choose to make a mobile app? Why did we choose to use a menu-based system? Why did we decide to use an icon-driven interface? Why did we choose to make input speech-based?

Step 2: give details on every item on your list Use pictures, screenshots or diagrams where they can help the

reader understand your design Creativity is welcomed as long as: It’s obvious what the major design decisions are An engineer would be able to build your design based on your description


5. Rationale for every design decision that may influence your solution's effectiveness

After you've given the details of your design, explain the reasons behind your design

Include your user research, results of your user tests, and design principles covered in course readings and lectures as justifications for your choices


Presentations (on Wednesday)

Include: Your design question Describe user research Show ideas from ideation Show demo of prototype Describe what you learned from evaluation


Presentations – Basic Principles

Use pictures more than words! Show images of visual elements of your design,

don't just describe them Explain processes with diagrams. A good diagram

will visually convey the process using as few words as possible

You can test the effectiveness of your diagrams by showing them to someone who is not familiar with your project


BREAK – 5 MINUTES


TRENDS IN UCD


HCD Considered Harmful (Norman)

Activity Centered Design Definition? Example?

Do people always adapt to the technology? Can you think of examples/counter examples?

When is HCD/UCD the right way to go? When is it not?

Other thoughts and reactions?


Usability evaluation considered harmful


Future Trends (Sears & Jacko)

Six questions to 5 members of the HCI community What are HCI’s 3 grand challenges? What are the three most important relevant

results from the last 10 years? What are the exciting emerging domains? Most innovative changes in next 5 years? What do educators need to change? What is the future?


Grand Challenges Carroll

Organizational issues, Ubicomp, End user programming, Collaboration Ogawa

Integration of telecom & broadcast, HCI for mobile appliances, communication tools (“cyberspace”)

Rau Make HCI profitable, new methodologies, impact user experience (e.g., “killer apps”)

Salvendy Science base for HCI, comprehensive education program, push the needed technology

Stephanidis Universal access, HCI theories and methodologies, digitization of HCI practices

Kientz Scaling novel computing technologies, personalizing technologies in meaningful ways,

supporting activities and long-term goals


Important Results Carroll

Interactive information visualization, collaboration via the web, powerful information retrieval tools

Ogawa Universal designs, portable devices, dispatching individual information (e.g., blogs and

homepages) Rau

Website usability, UIs for handheld devices, cellphones & mp3 players Salvendy

Concepts, metaphors, and tools; visualization, adaptive interfaces Stephanidis

User-centered approach to design, computer accessibility, user interface personalization Kientz

Usable mobile devices and always-on internet (e.g., iPhone), sensing activities of human behavior, shift to engaging user experiences rather than goal-oriented tasks


Exciting Emerging Domains Carroll

Security and privacy, universal accessibility, applications (e.g., healthcare), affect Ogawa

Portable devices for elderly, search functions Rau

Emotional design, computer games, smart environments, cross-cultural designs, fun Salvendy

Nanotechnology, different cultures, system science Stephanidis

Class Activity: Envisioning the future

In small groups, come up with YOUR answers to three of the questions posed by Sears & Jacko What are HCD's grand challenges? What are exciting emerging domains? What are the innovative changes of next 5 years?

Spend 10 minutes, then we'll share


Stephen’s Questions According to “Fundamentals, Evolving Technologies, and emerging Applications,” (Sears

and Jacko), computing has been moving off the server, off desktop, and into personal portable devices. Why is this happening? What will HCI become without computer?

In the near future we will see full integration of services. For instance telecommunication and broadcasting. What are the challenges related to such integration?

As per “Human-Centered Design Considered Harmful,” quite a number of products such as automobile have been designed without the benefit of user testing and the methods of human-centered design. Why do these products still do well?

It is evident that people are very dynamic in terms of needs such that today’s design will seem irrelevant or inappropriate tomorrow. Why does this happen? What does this mean to designers?

In reference to “Usability Evaluation Considered Harmful,” usability evaluation is critical in validating research ideas and products at various phases of design lifecycle. What are some of the situations where usability evaluation is considered harmful? Why?


Stephen’s Questions Between people and technology what adapts? Since HCI is a very dynamic field, and nature of interaction changes as

time goes by, HCI is therefore susceptible to facing quite a number of challenges. What are these challenges?

Premature usability evaluation can help designers in solving some of the problems early enough. On the other hand, Saul Greenberg and Bill Buxton write that premature usability evaluation can eliminate promising ideas. What are the pros and cons of premature usability evaluation?

Industries have been creating internal departments/groups which specialize in usability testing. What are the advantages and disadvantages related to this?

How does culture influence product evolution over time?
