  1. Computer-Mediated Communication / Computercommunicatie A Master IK, CIW, MMI L.M. Bosveld-de Smet Hoorcollege 1; ma. 4 sept. 2006; 16.00-18.00

  2. Two new areas of study • Human-Computer Interaction (HCI) • Computer-Mediated Communication (CMC) • Definitions • Application areas • Relations

  3. Human Computer Interaction: definitions • A discipline concerned with the design, evaluation, and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them (ACM SIGCHI, 2002) • The study of the relationships which exist between human users and the computer systems they use in the performance of their various tasks (Faulkner, 1998)

  4. Human Computer Interaction: definitions • The study and practice of usability (Carroll, 2001) • A science and an art: scientific foundation of HCI vs. HCI applications: usability engineering (Shneiderman, 2002) • There is no such thing as HCI; there is only HHI (Hatton)

  5. HCI: years 60/70 Software psychology Cognitive science

  6. HCI: years 90 and later Usability engineering Groupware and cooperative activity

  7. HCI concerns • “Will computers ever become easy to use?” Jef Raskin in Communications of the ACM, 1997 • “Credit for computer crashes?” Ben Shneiderman in ACM Ubiquity, 2000 “Every time your machine crashes, you should get a dollar from the supplier, and every time you get a dialog box you don’t understand, you should get a nickel.”

  8. CMC: definitions • A relatively new but rapidly growing form of interaction (Lee & Nass, 2002) • The process by which people create, exchange, and perceive information using computer systems that facilitate encoding, transmitting, and decoding messages (December, 2003) • The communication that takes place between people via the computer (Herring, 1996)

  9. CMC: at its broadest, at its smallest • At its broadest CMC can encompass virtually all computer uses (Santoro, 1995) • In general, the term CMC refers to both task-relatedand interpersonal communication conducted by computer. This includes communication both to and through a personal or mainframe computer.(Ferris, 1997)

  10. CMC: application areas • Computer conferencing • Electronic mail • News groups • Listservs • Discussion forums • Internet Relay Chat • Computer-assisted instruction

  11. CMC: promises? • Communication • Social interaction • Exchange of information • Opportunities and limitations.

  12. CMC: benefits over F2F meetings(Sproull & Kiesler , 1986) • Equal participation • Greater diversity in brainstorming

  13. CMC: reduced social cues • Due to often only text-based interaction • Consequence: deregulated interpersonal behavior: • Flaming • Detachment • Decision aversion

  14. CMC: Media Richness Theory • Media have different abilities to reduce ambiguity and uncertainty. People will most likely choose the medium that reduces these elements the most.

  15. Low ambiguity/uncertainty High ambiguity/uncertainty Face to face Video conferencing Telephone Instant messaging Letter E-mail CMC: ambiguity/uncertainty scale

  16. What do you do when? • Write a letter • Send an e-mail message • Send a SMS message • Use the phone

  17. HCI and CMC: differences • HCI: victim – controller interaction • CMC: victim – victim interaction • Social interpersonal interaction • Neutral task-related interaction

  18. CMC: specific topics • Interaction and interaction styles • User interface design • Usability evaluation methods • Groupware • Visual communication: Information visualization; Diagrams and diagrammatic reasoning

  19. Goals of the course • Get acquainted with some interesting topics in HCI and CMC • Get more insight into the problem of usability in various contexts. How to achieve a system that qualifies as: • Useful • Usable • Used • Critical thinking about approaches and propositions provided in the literature

  20. CMC: het vak praktisch gezien • 15 weken: 1-7 en 9-15 • 10 ECTS (280 uur) (18,67 uur p.w.) • Hoor/werkcollege: 2 uur p.w. (toelichting bij, discussie n.a.v. literatuur) • Practicum: 2 uur p.w. ((programmeer)opdrachten (VB)) • Toetsing: referaat/opdrachten (1/2) + eindtentamen (1/2) • Literatuur: hoofdstukken uit diverse boeken, artikelen, reader
