CHAPTER 4 EXISTING <strong>DESIGN</strong> STANDARDS AND CHALLENGES 4.1 INTRODUCTION Many design standards currently exist for television and the Web, the two base platforms for interactive television. While new potential platforms such as 3G mobile devices and the Sony PSP are beginning to enter into the market, bringing with them new sets of design issues, the vast majority of iTV applications are intended for output onto either a television screen or a computer monitor. It is important, therefore, to understand existing design standards for these two mediums. It is clear that effective cross-platform or convergent design will be essential for successful iTV programming in the future. The television and the Web each afford very different types of user experiences, and designs created for television rarely translate directly to a compelling or functional experience on the Web, and vice versa. By briefly surveying common design problems and existing standards for television and the Web, I examine the ways in which we might adapt these guidelines, and make recommendations based upon the functional differences between the two mediums, in order to contribute toward the establishment of the best set of guidelines for iTV design. I begin with some basic elements that are applicable to principles of good design in general, regardless of whether the target is a television screen or computer monitor. Subsequent sections will expand on the different standards for each of the two mediums in greater detail. 79
4.1.1 Grid-Based Design Grid-based design is essential to the development of effective information systems. Grids are the backbone to any effective visually-perceived design, regardless of the medium, as they help to promote consistency and predictability, two essential elements of any well-designed system (Lynch & Horton, 2002). According to Jute, “the primary purpose of the grid is to create order out of chaos. The grid helps the consumer to find material in the expected place every time… This primary purpose holds true even with projects which tend by their very nature toward disintegration. Thus it forces the designer to think constructively, and in a structured manner” (1996). He goes on to outline the three practical purposes grids serve: Repeatability. Repeatability is achieved by using one or more of the application tools of the grid to make similar pages in multi-page designs look the same, or to give multiple single designs a unity of appearance, or to give a multiplicity of designs for varying purposes a “corporate identity” for a single organization… Many people value the benefit to readers of finding material in the expected place every time so highly that they would consider repeatability the chief ornament of the communication function of the grid. Composition. The grid incorporates the compositional wisdom of the ages into a format that is rigid in aspects where flexibility would be disastrous, and flexible in varying degrees precisely as required for matters where you must apply initiative and taste. Communication. The purpose of graphic design is to communicate the message. Period. Positive communicative aspects of the grid are that readers can: rely on finding given elements in the same place; rely on the designer to guide them to 80
