eReaders need to add more “book like” cues. I play solitaire a lot (too much?) on my iPad. I wish I could see how many cards were left to flip over. It would be easy for the programmers to provide that information. The could add a shadow or show the edges of the cards. But they don’t. Similarly, eBooks don’t provide tactile information about where you are in the book. They can’t provide tactile info, but eReaders could provide some better cues. Have you ever closed a book and later had to locate your reading location? Have you ever tried that with an eBook? What is fairly simple with a real book is extremely difficult with an eBook. But is that inherent to the medium or something that can be ameliorated by better user interfaces? I think the latter. A recent study at the University of Washington, with Computer Science students, identifies the problem but seems to treat it as inherent.
