Exploring the Relationship Between Effective Reading and Human-Computer Interaction

This paper by Barbora Drobíková and Richard Papík investigates the interplay between effective reading and human-computer interaction (HCI). It emphasizes how visual perception significantly affects information processing, highlighting the advantages of visualized data over text. The research discusses ergonomic considerations and the impact of reading mediums (screen vs. paper) on user performance. With insights drawn from psychological studies and usability principles, it underscores the importance of clarity, distinctiveness, and readability in information systems. Future directions and recommendations for HCI practices are also explored.

  1. Relationship between effective reading and human-computer interaction Barbora Drobíková and Richard Papík

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

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

  4. 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 Nov 10, 2008

  5. 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 Nov 10, 2008

  6. Reading as perception of text

  7. Cybernetic reading model

  8. 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 Nov 10, 2008

  9. 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 Nov 10, 2008

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

  11. 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 Nov 10, 2008

  12. 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). Nov 10, 2008

  13. Future? Nov 10, 2008

  14. A question?A suggestion?A protest?Thank you for your attention Richard Papík Barbora Drobíková
