Figure 5.44 History IQ System Feedback Finally, consistent audio feedback, if available, is important to user interaction as well. TiVo’s trademark series of sounds, designed by a sound engineer using wood blocks and other percussion instruments, sets a good example. “You hear the bloop- bloop-bloop; it’s kind of friendly. It’s cute. It makes it very intuitive. You know what’s going on without watching,” says one TiVo fan. Another fan relates, “When I do a lot of my TiVo maneuvering, I don’t even look at the remote, I listen.” The importance of good audio feedback is underscored by Donald Norman: “Sounds are critical… You have to spend the same type of attention to designing sound as visual appearance. Companies these days always hire graphic artists. They need to hire sound artists” (quoted in Fernandez, 2004). Principle: Use appropriate cultural mental models and metaphors A metaphor transfers something well known and familiar from the every day world of the user to the organization of data displayed on the screen. An example of a metaphor utilized in a graphical user interface is the trashcan of the Mac OS, or the 169
ecycling bin from Windows, that stands for the deletion of files. Human-computer interaction experts agree that metaphors can both be helpful and harmful. For example, metaphors that are too literal can be too constraining to the design; on the other hand, metaphors that are too abstract can fail to do its job. Metaphors, therefore, should be used appropriately and with caution. Figure 5.45 illustrate PBS’ Cisco’s Journal application, which uses the journal / scrapbook metaphor to tell the story of Cisco and his family. The application is successful in keeping the metaphor consistent throughout the application. In addition, the metaphor is integrated into the television component of the show, where each week viewers actually watch Cisco – an electronic artist – sit down at his desk and work on his online “journal.” (a) (c) (d) Figure 5.45 Pages from Cisco’s Journal (a), (b), (c), and (d) 170 (b)
