Tufte's first two books concentrated on the print medium, where he is comfortable and knowledgable. This book steps into the computer graphics domain, where his knowledge is only partially applicable.He fully recognizes the problems related to the limited pixel resolution of the computer screen, but he doesn't know what to do about it. In his example screens for the Museum kiosk, his vision is clear but impractical. He knows what should be done if more screen resolution were available, but fails to show how his vision can be embodied in the computer screens we really have available.I hope Tufte will rethink the subject and figure out how to properly apply the high temporal resolution of the screen to make up for its low spatial resolution.
