Relationship between effective reading and human-computer interaction Barbora Drobíková and Richard Papík
HCI and information science • user • end-user • user behavior / information behavior • user = reader Nov 10, 2008
Cognitive processes • following human senses are frequently usedby modern computer and information systems for communication purposes: • Sight • Hearing • Touch 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 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 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 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 Nov 10, 2008
Internet role • boom of online systems and variety of information users (children, students, scientists etc.) • new dimension of research 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 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).
