1 Infotech Seminar, Oulu, November 11, 2005 Informaatioteknologia vaikuttaa ihmisten käyttäytymiseen ja asenteisiin Prof. Harri Oinas-Kukkonen Dept. Information Processing Science University of Oulu Outline The Current The Web The Mobile The Goal

2 The Current The easy to use dictum If ease of use were a virtue in itself, of course, we would all be riding round on tricycles. They are, after all, much easier to ride than two-wheeled bicycles. {A free quote from Douglas Engelbart}

3 Would you really want to stay here? Stronger emphasis on the usefulness of the software systems Yet, both are needed. Moreover, they should not be separate categories. In fact

4 Usefulness and ease-of-use should be studied together This togetherness requests for an integrative approach. The Information Systems Science A discipline that adopts an integrative approach. An old discipline within Computer Science.

5 What are information systems after all? Not combinations of software and databases, but... organization(s), people, software, databases, services. People are an integral part of an information system and not only users of it

6 This simple observation affects the whole nature of how systems should be designed The Web

7 Web information systems design Web pages are often parts of a complex information system. Web applications are still far too often designed simply in the form of Web pages. More attention should be paid to (Web) information systems design rather than Web page design. Deeper understanding needed Hypertext functionality Semantic Web User modelling Organizational issues Systems integration and others

8 The Mobile The mobile is BIG in Finland. Yet, the Internet already builds upon human mobility Developing Web and mobile information systems separately is out of the question for companies seeking competitive advantage. Mobile ISs and Web ISs should be treated as aspects of a single entity, a single information system. Mobile-aware Web information systems

9 The Goal The improvement of the quality of life through technological innovation. {The Finnish Technology Award Foundation} To achieve any of this social innovations are needed Motivating people to do their work better or more safely Inspiring people to adopt more healthy living habits

10 Transformation Computer usage has shifted from data processing into everyday life A variety of roles for computers Teachers, coaches, doctors, salespeople, others Attitudes and behavior People often treat media, television, and computers as other people or physical locations (Reeves & Nass 1995) Information technology may be, will be, and is being used to affect people s attitudes and behavior People need to understand the various methods and techniques used Developers need to be capable of employing sound design principles in an ethical manner E.g. being open to one s own biases, and revealing those

11 How? Making target behavior easier to do Leading people through a process Performing calculations or measurements that motivate Allowing people to explore cause-and-effect relationships Providing people with vicarious experiences that motivate Helping people rehearse a behavior Rewarding people with positive feedback Modeling a target behavior or attitude Providing social support Wrap up

12 Summary Usefulness Usefulness and ease of use Information systems design Mobile ISs and Web ISs Attitudes and behavior Thank you!
