  39. 39. Abel<br />Student – 12<br />Abel lives in the city of Beira, in Mozambique. Abel goes to middle school. He also helps his mother in the fields and takes care of his younger brother and sister. His native language is Cyiao, his second language Portuguese. There are no computers at school, but his family has a cell phone. When it’s his turn to use it, Abel uses the phone to study, check the results of the football games, and take photographs. Whenever someone else asks him to use the phone, he proudly hands it over to them.<br />I want to be an engineer, so I have to be very good at Math, Portuguese and English – and the apps help me do that. <br />I wish there were more images on the screen.<br />II.

  40. 40. Florine<br />Student – 15<br />Florine is in high school, but she does not like to study. She lives with her parents outside Brussels. Florine sings in a band. She loves technologies. She uses her Macs (Pro, Pad, Phone, and Pod) to be constantly in contact with her friends, listen to music, update the band’s website, and promote their songs on YouTube.<br />My Macs are my freedom. The Internet my extension – except when I went to Madeira. That really … me off!<br />II. PROFILESPersonas<br />40<br />Source: Norman 2011<br />

You see, he’s more of a people person. He loves to be with his friends, and most of all his girlfriend.<br />I like a good story. I can’t stand waiting for things to happen on the computer. When something’s taking too long, I switch to another site. <br />When I find something interesting, I use the keyboard to move around – it’s faster. <br />II.

  42. 42. Noha lives in Alexandria, Egypt. She speaks Arabic, and some English, French, and German. She divides her days between her family, and work. She is a religious person. She sympathizes with the democratic party. Noha uses the Internet every day at work. At home, she uses it to buy things for the family and talk to her friends. <br />The internet is very important for my research. To log data, and search for information. The laboratory where I work subscribes many journals, mostly in English. I read English well, but I need to speak it better. Much better. I want to go to the States to do a postdoc. And I need to write, and publish my own articles in well-known peer-reviewed journals.<br />نهى<br />Noha<br />Researcher – 29<br />II. PROFILESPersonas<br />42<br />
  43. 43. Duarte<br />Businessperson – 33<br />Duarte is from Lisbon, Portugal. He speaks English very well. Duarte likes radical sports. Two years ago, he founded his own nanotechnology company, and he’s already selling his products to Asian countries, the States, and other European countries. He has 3 cell phones, and two laptops, one in the office. The other one is always with him.<br />The company is growing fast – and this is just the beginning. I’m looking for a good webdesigner, someone that can make the website appealing to all the markets.<br />II. PROFILESPersonas<br />43<br />
  44. 44. 馮慧靈 | 冯慧灵 | Feng Huiling<br />Manager – 38<br />Feng Huiling lives in Shanghai, China. She is very friendly, though reserved. She lives in small, simple apartment with her husband and daughter. She goes to work by bicycle every day. Feng Huiling is the manager of a restaurant in China. It is a very demanding job, requiring great effort and dedication on her part. There is nothing about the restaurant management business that she does not know. The restaurant has one computer, that everybody uses.<br />I asked my friend to make a site for the restaurant with a garden on the first page, not a ‘desktop’. It will be full of information. I like gardens. I like images and a lot of color, specially red. It’s my favorite.<br />II. PROFILESPersonas<br />44<br />Sources: Lo e Gong 2005; International Business Cultures<br />
  45. 45. Greg<br />Writer – 42<br />Greg lives in the the States, in the small city of Ames. When he was 28, Greg had an accident that left him paralyzed from the neck down. He is married and has three children. He has a large network of friends, including the doctors, nurses, and other people that take care of him, but he likes to be as independent as possible. He is writing a book about his life, by himself on the computer.<br />I want to try the new sip-and-puff pen Maria told me about. A Portuguese man invented it, I believe, and he’s the only one selling it. Have to check out his website.<br />II. PROFILESPersonas<br />45<br />
  46. 46. Luís<br />Clerk– 45<br />Luís is from Barcelos, in Portugal. He works as a clerk in an import-export company. Luís has photosensitive epilepsy. He finds it difficult to distinguish images on the screen, in spite of wearing glasses (which takes off when taking photographs). <br />I like my colleagues, and the work I do. But I can’t distinguish the colors and letters well. If only I had a bigger screen … but the situation is so bad, I don’t dare ask the boss for one. <br />When I retire, I might start my own business. Probably a webdesign company, but for people with disabilities. We badly need one in Portugal. I’ll never forget the day when I wanted to get my son a surfboard, but the letters were so small I could hardly see them, and the navigation was a total disaster. In any other place, I would have taken them to court.<br />II. PROFILESPersonas<br />46<br />
  47. 47. Irina lives in Moscow, Russia. She is a library assistant at Moscow State University. The university became fully automated recently, but Irina found it easy to adapt because of the various training courses the university provided. A few months ago, she needed a consultant in customer service, and could not find one. <br />I suddently realized I could be the one to start a consulting firm and give courses in customer service. So I began searching the Internet. I saw what other people were doing in other countries, and I sent them emails and spoke with them. I learned a lot about starting a business. <br />II.

Esteban lives with his large family, for whose well-being he feels totally responsible. He plants corn and soy. He does organic farming. He has been so successful that farmers from India and Africa often come to his farm to learn about his methods and results. <br />The new technologies help me keep up-to-date on my field, and talk to my family when I’m away. <br />I don’tlikepagesthat are toocrowded.

She was born in Wiesbaden. Her husband is Portuguese. Helga hates wasting time and words. She believes in the value of clear, concise, objective writing. She plans everything to the last detail. <br />I don’t have time to waste. And neither do users. <br />Web interfaces have to be adapted to the different cultures and nationalities, but also to the more universal factors of perception and cognition.<br />I have rheumatism in my hands. Some days it’s a bit difficult to use a mouse.<br />II. PROFILESPersonas<br />49<br />Source: Kostelnick 1995<br />

His native languages are Konkani and Hindi. He also knows how to speak English and Portuguese. Suresh is very agileand energetic. He has a computer at home that he uses to talk to people wanting to buy his work. <br />The problem are the languages. In India, no one wants to buy my work. In Europe, the States, and other places, they do. I don’t know how to write English. And I can only write a little Portuguese. My grandchildren taught me how to speak to people through the computer, instead of writing. Like this, I don’t even need an intermediary. I sell my work directly to the clients.<br />II.

She is married and lives with her husband in a large house and grounds, a few miles away from Auckland. She has a desktop computer, a mobile phone, and an iPad. For some time now, she’s been using the computer for daily tasks, like making doctor appointments, checking her bank statements, and doing shopping.<br />I’m quite used to doing things online. And I don’t mind paying more for a computer that is the exact match for my needs. The iPad, for instance, has been a great help lately.<br />II.

She has difficulty reading and writing because she spent all her life in the same out-of-the-way village in the hills. Joaquina is a wonderful storyteller. Every day, at the end of the day, she sits on a bench in front of her house, thinking about this and that, and chatting to anyone going by.<br />Now eveybody’s got a cell phone and a computer. I don’t understand any of that. The other day, I heard the government wants us to do everything on the Internet. I live by myself, and have a small pension. My neighbors too – we’re all on the same boat. I don’t know what I’m going to do… Nothing, I suppose…<br />II. PROFILESPersonas<br />52<br />
