Cost Effective Full Touch Screen Mobile

Samsung presents Star 5233

The good: Responsive, bright touchscreen; built-in links to social-networking sites; expandable memory card slot; good battery life.

The bad: No 3G connectivity; poor YouTube quality; troublesome USB connection; user interface can be confusing; no headphone adapter.

The bottom line: The Samsung Star does a good job of scaling down touchscreen tech to fit in a pocket-sized, bargain-basement phone. A bright, responsive touchscreen ensures that basics like dialling and texting pose no problems, and the 3.2-megapixel camera is decent too. But, without 3G, the Star doesn't so much surf as paddle the Web.

Wet PC

Originally conceived and developed at the Australian Institute of Marine Science (AIMS), the WetPC underwater computer combines a comprises a miniature PC with a mask-mounted virtual display and a unique 5-button chordic graphical user interface (CGUI) that can be operated using one-hand.

The computer itself sits in a waterproof housing on the diver's air tank and is attached via cable to the mask-mounted display that produces high contrast "floating" visual interface.

The waterproof 5-key Kord Pad is attached to the diver's belt or chest and is operated by pressing single or multiple keys This process (called chording) is likened to playing a piano allowing the user to interact with the computer in a very natural way. The pad can be used with either hand and enables the diver to access and record information with one hand whilst swimming.

The Kord Interface Technology is completely distinct from other systems because it displays graphic buttons on the screen that match the buttons the user needs to press on the hand-piece to perform a particular action - this makes underwater computing a far more user-friendly prospect.
