Questions?


Sketching Critiques – 20 minutes

Break into groups of 3 people Take turns showing and explaining your 3 sketches

with each other Critics should offer advice and feedback about the

idea Strengths, Weaknesses, Originality, Feasibility Sketcher: take notes about what feedback was offered Critic: be critical, but constructive and courteous! Each critic should sign and date the page after the sketches

State of User Centered Design Practice (Mao et al.)




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?


Participatory Design (Spinuzzi)

What is it? Why should you do it? What advantages? What disadvantages?


BREAK – 10 MINUTES


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

Services, multimodal interaction, cooperation, access to information, robots Kientz

Healthcare (especially preventive health and public health), games with a purpose, ubiquitous computing


Innovative Changes of next 5 years Carroll

Cell phones, agents Ogawa

Agents/robots Rau

Wearable & ubiquitous computing Salvendy

Disappearing computer, miniaturized computing systems, intelligent interfaces Stephanidis

Mobile interaction, home environment, biometrics Kientz

Personalization of computing, activity-based computing


Visions of the Future

Where will human-computer interaction be in 10 years? 25 years? 50 years?

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


Design specs(Sit with your project groups)


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 P4 requirements are based on good practice


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

For P4: engineers Who else might be your audience?


2. A clear description of the design problem. In your project groups, read section 1, “The Problem” Discuss how Travis presented the design problem and

how he made the goals of his design really clear. Think about:

The language/writing style How he breaks the problem down How he introduces his 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.

In your project groups, discuss your project scope What's in the scope, what's been left unspecified

Be ready to report back to the class: The scope of your project (in one sentence) 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. 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


4. Details about every major design decision within your project scope. In your group, make a list of all of the major design

decisions within your project scope. Discuss how you will present the details of those

decisions. e.g. Will you use personas and scenarios? Will you do something completely different? What will that be? Will you use images? What kind of images?


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.


Presentation

Basic principles to work from: Show images of visual elements of your design, don't 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.
