User tasks influence which device is appropriate fro particular types of information Device coordination is critical. Be sure that the information on different devices is coordinated, consistent, and up to date Combine the coordinated information guideline with the appropriate device guideline. Information about the same thing can be presented in more than one way. For example, information about a room can be conveyed in a picture, a text description, or a floorplan graphic. Navigation through a house video is controlled on a schematic floorplan displayed on a PDA Source: Robertson, S., Wharton, C., Ashworth, C., & Franzke, M., 1996. There is little doubt that new technologies will continue to change the ways we navigate through iTV systems: “in the future, we may also see voice commands via one’s remote control or cell phone, speaker-driven commands for sound-sensitive TVs, touch screens on consumer televisions, lab devices for more complex interaction, and more” (Swedlow, 2000). As this occurs, design standards must continually be formed and redefined. ITV represents a new medium and a new space for expressive communication, one that is distinct from the viewing and computing platforms that have existed to date. The TV itself has fundamentally different display characteristics from conventional PC monitors, which are still different from mobile devices. As a result, good convergent design practices will be essential in order to create meaningful, compelling, and interesting interactive experiences. The principles presented in this chapter are a starting point. They serve to orient interaction designers and producers of iTV to a set of issues that any specific design may need to explore in greater detail. 175
CHAPTER 6 CONCLUSIONS AND FUTURE DIRECTIONS My goal in this document has been to formulate interaction design principles for interactive television programming in the United States. While gaining momentum, iTV has not yet enjoyed widespread success within the U.S. to date. The lack of standards across both the design and technical realms of iTV production, as well as between the two, is a crucial part of what makes successful iTV deployment a challenge: “This cross- media expertise requires the integration of good design principles with knowledge of the technical and database implications. The exclusivity of the platform designs of recent technologies and the current lack of a standardized data format have created for today’s designers many challenges in integrating the multiple distribution channels with the disparate databases, software programs, and applications” (Curran, 2003). I have attempted to contribute to the effort toward establishing principles for designing effective and compelling iTV experiences. Figure 6.1 illustrates the most popular user preferences for iTV applications. Not surprisingly, these popular user preferences speak to a number of the principles discussed in chapter five, such as giving users greater control, agency, and customizability over their viewing experiences (Pause, Rewind Live Shows, Additional Information in Shows, Additional Information on Ads, EPG), and convening an audience (Vote on Issues, Games, Interact with Other People). 176
