1. Nov 10, 2008 Relationship between effective reading and human-computer interaction Barbora Drobíková and Richard Papík

2. Nov 10, 2008 HCI and information science user end-user user behavior / information behavior user = reader

3. Nov 10, 2008 Cognitive processes following human senses are frequently used by modern computer and information systems for communication purposes: Sight Hearing Touch

4. Nov 10, 2008 Sight approximately 90-95% of information is forwarded to the brain for subsequent processing by eye-sight trends: information visualization research: large text databases, graphic user interface, software tools oriented to computer graphic research activities reflect the fact that human eyes (sight) interpret visualized data much faster and much more effectively than standard text

5. Nov 10, 2008 Psychological and physiological research 2nd half (part) of the 19th century 10s - 20s of the 20th century, especially American school of experimental psychology special reading research => reading courses

6. Reading as perception of text

7. Cybernetic reading model

8. Nov 10, 2008 Reading from screen vs from paper Dillon : Reading from paper versus reading from screen Dyson : How physical text layout affects reading from screen text variables – line length, character density, type size, characters per line, columns, window size, lines per screen etc. conclusion that reading from screen is by 27% slower than printed text reading

9. Nov 10, 2008 Screen and information perception 70s and 80s - experts of computer science, also HCI 80s - collaborative tools/systems in text processing (inf. science journals) during the 90s - information science, information and library schools

10. Nov 10, 2008 Internet role boom of online systems and variety of information users (children, students, scientists etc.) new dimension of research

11. Nov 10, 2008 Ergonomics and ISO 9241 full title is Ergonomic requirements for office work with visual display terminals (VDTs) importance of the ISO 9241 group norms for maintaining a dialogue with information systems

12. Nov 10, 2008 Timeless recommendations Clarity (the information is provided in a clear and precise manner); Distinctiveness (the information presented is distinct); Brief nature (users receive only information necessary for implementing their tasks); Congruity (the same information is presented uniformly in the same manner expected by the users); Ability to ascertain (the focus of users on the information requested); Readability (the information is easy to read); Lucidity (the content is clear, non-ambiguous, cognizable and can be interpreted).
