Principle: Simplicity An iTV interface design must be easy to understand, regardless of the user’s experience, knowledge, or current concentration level. Consumers tend to ignore designs that have too many bells and whistles. Mullet and Sano argue that the benefits of simplicity are functional as well as aesthetic in nature (1994): Approachability. Simple designs can be rapidly apprehended and understood well enough to support immediate use or invite further exploration. Recognizability. Simple designs can be recognized more easily than their more elaborate counterparts… they present less visual information to the viewer, and are more easily assimilated, understood, and remembered. Immediacy. Simple designs have a greater impact than complex designs, precisely because they can be immediately recognized and understood with a minimum of conscious effort. Usability. Improving the approachability and memorability of a product… [eliminating] unnecessary variation or detail make the variation that remains more prominent and informative. Achieving a simple design, which always works better for a broad audience, often means reducing a design to its essence (Herigstad & Wichansky, 1998). Figure 5.22, from the TV411 prototype developed at the 2004 AFI eTV workshop, presents good examples of a simple interface that is easily understood at a glance. 145
(a) (b) Figure 5.22 TV411 Interface (a) and (b) Common pitfalls in this category include designs that are too full of clutter and visual noise, excessive detail and embellishment, or elements that are not of interest to viewers such as excessive advertising content. Be aware of overly designed designs for the amount of information given. Earlier examples from MSN TV (Figure 5.23) and Gemstar-TV Guide’s GUIDE Plus+ (Figure 5.24) are examples of poorly designed interfaces that may intimidate users or make them more hesitant to approach the application.
