Abstract:

We are so accustomed to watching television that we easily overlook the limited resolution of the television screen. Compared to TV, even VGA looks good. Although both use a similar display monitor, they differ in both the way the screen is 'painted' and in how much information can be placed on the screen. To design effectively for interactive television, it is essential to understand the technical constraints of the medium.
