Eu estava preparando um artigo sobre usabilidade dos menus de DVD e resolvi pesquisar na internet pra ver se não estaria sendo redundante. Acabei encontrando um artigo do Don Norman que fala tudo:

1. Make important states explicit. There is no reason that the main menu page couldn’t show the audio, video, language, and subscript settings on the main page, so the user wouldn’t have to go to the pages and check them just to make sure they are what is wanted (or start playing the movie without checking, only to learn that the settings are wrong).
2. Speed up the transitions. Rapid response improves the user experience. Unnecessary animations detract from the experience after the first showing. If an animated transition is desired, keep a counter so it can be shown the first time, but not thereafter (The DVD standards provide for 16 general variables in RAM for counters, arithmetic, etc.).
3. Provide more feedback so the user knows what has been selected and what is happening. Make it easy to back out — return to the previous spot — if the new page is not what was wanted.
4. Develop industry standards for selection and cursor movements, perhaps for other parts of the experience. These parts of the design are not the place for creative excess; creativity can come about in other ways and places.
5. User test the result. Ask average viewers to do simple things, such as find a scene of interest. Ask them to change DVD settings, etc.
6. Consider accessibility: the principles discussed in the NN Group’s recent guidelines for making websites and intranets easier to use for users with disabilities also apply to DVDs.
7. Provide more information. Why not state the duration of each item in the Special Menus, with a brief description, instead of the now, often cryptic titles, often chosen more for cleverness than for informativeness? Do as book authors learn to do: use a clever title, with an informative subtitle (e.g.: “The Invisible Computer: Why good products can fail, the PC is so complex, and information appliances are the answer”).

Seguindo um dos links, acabei entrando na Amazon e lembrei de uma série de livros que ainda não tenho e montei uma “wish list”. Portanto, se você está pensando em me dar um presente, considere um desses livros.
