I am fully aware that wireless and mobile access are the newest of the new in computer science and the subject of the workshop where this paper was published. I also know that video is important in making use of fourth-generation (4G) cellular phone networks’ increased total bandwidth. Hence, my first thought was to be impressed by the demo’s screen shots, such as Figure 1 that shows moving video from one friend and 16 still frames from other friends.

My second thought was that this paper must be an impostor in a wireless and mobile access conference, because its demos would be usable on a 21-inch monitor but useless on a 3.5-inch cellular phone screen. The third thought--noting that Figure 1 itself is only eight percent larger than a cellular phone’s screen, that the surrounding half-inch frames were identifiable in the figure, and that they would be easier to view on a color liquid-crystal display (LCD) screen--led me to the realization that the paper does belong in this workshop, after all. Unfortunately, Figure 4 elicited the fourth and final thought: the text’s hundreds of words would only be readable on a 21-inch screen. Even an enormous increase in resolution would only make the screen readable using a microscope or heads-up display (HUD).

I therefore conclude that the paper’s demo was conceived and tested on the same large desktop screen on which the paper was written. Even so, there is much to admire in the demos and architecture.
