It looks cute, but for a flash card app other interaction methods are just as quick and easy, maybe more so. Now, if something like this could be used so that a person could see, for example, their next appointment by peeking, but fully opening the cover activated the iPad normally, that would be cool.
yeah, I agree. I tried it and it was very interesting but the interaction was very bad. For instance, you can't peek then close and think ... once you peek you have to open all the way or it will move to next question.
I appreciate the imaginativeness of it but it isn't really an enjoyable interface for long term use.
