Thoughts about multiple screen interfaces.

Now the "Touch" interface thing got us talking about how we could see it working in the future:

You could have 2 screens (they are getting cheaper all the time):

1. one for (horizontal) for navigation/display/input  (replacing keyboard and mouse)
2. another (vertical) for display.

 The idea being that it's a lot less strain to drive things horizontallly. Additionally, with 2 screens, your hands aren't going to constantly be obscuring the areas of interest.

A really cool thing would be if the input screen was flexible. This would mean when keyboard input was required, a keyboard imprint could be raised from behind the screen, to create a keyboard with tactile feedback from the screen.

Another similar idea exists for the eBook format. Here you could have a book shaped device with 2 screens, one each side. To go to the next page, you turn it around, (right edge first). Previous page, turn around (left edge first). The 'next' page could be pre-rendered as soon as you turn (effectively double-buffering), this means the page turn speed is a quick as you can turn the device. I think this would be quite a natural way of reading, with NO buttons or pressing of anything.
