Ceatec's coolest gadgets

Sharp LCD with optical scanner
If you think the iPhone screen's two-finger touch is cool then Sharp has something for you! The company showed a prototype 3.5-inch screen which integrates an optical scanner pixel alongside each LCD pixel. This means the screen can scan objects such as name cards placed on its surface and recognise fingers or other objects. Because it's determining the position of fingers from a scanner input and not a touch screen, it's possible to touch the screen in more than two places and have all fingers recognised. The panel is still a prototype but commercialisation is expected in the first half of next year. Samples are already in the hands of potential customers but Sharp wouldn't name those companies. Whoever they are, you can be sure some are trying to outdo Apple's iPhone!

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
