Prototyping 3

What We Will Do?

• Students will form small teams 2-3 members;• Each team will ideate own concept of application;• Series of workshops in a class aimed very

different deliverables;• Some home works on improvement of

deliverables;• Full spectrum of prototypes at the end of the

course

Prototyping 5

What is the Topic?

AGING

Prototyping 6

WHY AGING?

Prototyping 7

Reasons for the Topic Selection

1. Aging is a high actuality topic nowadays;2. Focus on aging makes job hard and

challenges for uneasy solutions;3. Focus on aging brings accessibility in place

and gives a chance to learn about universal design;

4. Design with focus on aging develops empathy ─ a key ability of the good designer

The First Task, 15 minutes (use Google!)

• Do a fast brainstorming in groups:1. Try to identify, several changes, which will take a

place when an amount of old people will rise up dramatically?(Example: amount of people who can do hard physical work will be reduced)

2. Which problems society will meet?Write down a list of the problems(Example: Lack of ‘Blue Collars’ workers)

3. What can help to answer these challenges?(e.g. Robotization, development of bionic tech)

4. Report your findings to others;5. Save the list of problems for the

future work

Understanding Vision

We use information from the visual sense in order to move around and interact with objects and environments. The effective design of any product or environment should take into account the range of human visual abilities

Four Functions of Visual System that are Discussed in the Context of Designing Products

1. Visual acuity — the ability to see fine details of objects;

2. Contrast sensitivity — the ability to discriminate between different brightness levels

3. Color perception — the ability to distinguish between different colors

4. Usable visual field — the ability to use the whole of the visual field to perceive detail in the area being looked at and the surrounding area

Major Hearing Functions that are Considered in Design Applications

1. Sound detection — the ability to detect beeps, tones and other sound output from various products

2. Speech discrimination — the ability to detect and understand speech in quiet and noisy environments

3. Sound localization — the ability to tell which direction a sound is coming from

Speech discrimination

Following a conversation is more difficult in a noisy environment, especially for those with reduced ability to discriminate speech

Sound localization

Reduced sound localization ability could lead to fatal consequences in busy environments

The ability to understand announcements and speech depends on the background noise level

The task two, 15 minutes

• Work in the group again:1. Refer to the list of the challenges you have

indentified in the first task;2. Try to identify, people of which age will be

affected by these challenges?3. Try to identify, which abilities of these old people

could be affected by these challenges?4. Report and reason your findings to others;5. Save the list of abilities for the future work

Prototyping 53

Homework: Research

1. Try to find an old person who can anonymously participate in your study. She or he can be a relative, an acquaintance or a friend. Involve that person in to a discussion of their requirements;

2. Define the opportunities and threats for this person when considering her mobility, work, housing, or information/communication needs. Try to make pictures of artifacts that the user uses (respect privacy!). For example in the field of mobility, some possibilities are:

Wanting/needing to continue getting around Maintaining independence

3. Be ready to present your work on the next lesson

Suggestions:• Develop a series of questions you want to ask the end-user, including e.g. whether to

focus on walking, driving or public transport.; • During the interview fill in an empathy map;• Identify tasks/activities that cause particular problems for that person;• Define the user’s needs

Guidelines for Interviewing1. You may bring a few prepared questions, but the most important thing is

to maintain a connection with the interviewee and show that you are listening to what they are saying (ie, look at them, not just at your notes). Also, you should always follow up on interesting answers, instead of mechanically moving through a list of questions;

2. Take notes or record the interview. Capture on paper the person’s own words whenever possible, instead of rephrasing during the interview. If you record the audio of the interview (with permission), you will need to extract quotes from the recording later;

3. Start the interview by introducing yourself and the project you are working on, and start with lighter, more general questions to establish a connection and put the interviewee at ease;

4. Listening is as important as talking (your interviewee should talk about 75% of the time). Also, showing that you are really interested in what the other person has to say goes a long way. Think of the interview as a conversation

Prototyping 57

Guidelines for Interviewing5. Ask open-ended, non-leading questions: “What do you think about that

school?” is a better question than “Don’t you think that school is great?” The former doesn’t imply there is a right answer;

6. Be curious and ask “why?” often, even when you think you know the answer. Many answers will surprise you. Always follow up on answers that sound interesting, or whenever the interviewee says “I think...” A good way of doing this, in addition to asking “Why?” is to say “Tell me more about that.”

7. Ask for stories about concrete events. Instead of asking people how do they "usually" do things or how do they "usually" feel, ask them about the last time they did something, or the most memorable moment (in fact, do NOT use “usually” at all).

8. Don’t be afraid of silence. Resist the need to ask another question when there is a pause. The interviewee might reflect on what he/she has just said and say something deeper
