Likewise, the following two examples, from TLC’s Trading Spaces: Home Free (Figure 5.39) and the 2004 Olympics on NBC (Figure 5.40), both provide viewers with clear instructions on how to vote by SMS via a mobile device. Figure 5.39 Trading Spaces: Home Free User Instructions Figure 5.40 Olympics on NBC User Instructions Principle: Minimize clicking / distance from primary screen The activity of clicking excessively is one that is conventionally annoying to users both on the television and the computer. In particular, using a remote control for selection can be a reasonably strenuous activity relative to using a mouse. Therefore, with 163
applications based on the television, iTV applications must be navigable using only a remote control, with the four directional arrow keys and a select key. With the navigation limited in this way, designers must take special care in the arrangement of navigable and selectable objects on the screen. For example, it may be a good idea to group functional buttons into one column and navigational buttons into another. Thus, moving from one group to the other requires only one click to the left or right. The BBC is a bit more constrictive and actually recommends that designers limit navigation to only one axis – either forward/back or up/down (British Broadcasting Corporation, 2002). In general, iTV designers should minimize the number of clicks that the user must press in order to navigate through the application. As well, these activities should not take the user too far away from the primary screen. According to research conducted by See & Woestendiek, environments with a depth greater than four often become disorienting and confusing to the user (1987). Taking users too far away from the primary screen increases the chances that they will become distracted or frustrated with the application. Dale Herigstad, who designed the interaction for the Queer Eye for the Straight Guy prototype at the 2004 AFI workshop, explains that his design purposefully attempted to move away from “the ‘page model.’ As illustrated by Figure 5.41, instead of clicking from page to page, the design keeps you in one kind of space, but one that is fluid, so that you click one thing and it generates something else. The design is all about transition” (quoted in Swedlow, 2004b). In another one of his designs, Woodrow Wilson, the timeline-based navigational structure that persists along the bottom edge of the application ensures that users never navigate outside of the iTV space or away from a familiar point (see Figure 5.42).Yet a third tactic may be to employ the picture-in-picture 164
