Accustomed to Google search so much, I sometimes look for “a search button” even when I read a real newspaper looking for a specific word. So it would be nice if there is a device like this to quickly find and highlight the word you specify. It would be even better if it can tell you the meaning of a word you don’t know. It’s so light and thin that you wouldn’t mind carrying it around at all. Oh, if there is a keyboard that can attach the screen to it, it’d be really good if it works as a computer.
Pubic billboards and spaces are so much filled with information that it takes you time to find what you really want. With this transparent sheet, only you can see the info you want on various places like walls, floors, ceilings, notice boards, etc. In a large building with many people coming for the first time, such as hospitals, this sheet could be handed to a visitor (especially a senior) as a guide. This way, what you see and how you see it can be customized.

I just wanted to say how much I too wish there was an apple+F function for my life. One day, soon, I hope.
