HDTV: even Octopuses prefer it

It's the frame rate that adds reality, scientists decide.

An octopus, yesterday.

An octopus, yesterday.

Apparently we aren't the only species to prefer the crisp, smooth picture of an HDTV compared to that from one of those old CRT sets of yesteryear.

A follow-up study of octopus behavior by the Journal of Experimental Biology shows that mollusks react to high-definition videos where they used to be nonresponsive to movies on a SD set.

Renata Pronk and colleagues from Macquarie University, Australia, decided to see if using an LCD display and HD video would fix the long-time problem.

In 2008, Pronk theorized the difference ultimately came down to the frame-rate, not image quality (at the time one in five HDTV owners couldn't tell the difference between HD and SD programming.) She said that standard definition video probably seemed more like a series of still images instead of a real object.

When a 50-frames-per-second, progressive-scan clip of a "tasty crab" was shown to an octopus caught from Sydney Harbor it reacted to the image like it was the real deal.

"The octopus jetted towards the screen and tried to catch the crab and eat it," Pronk says in the article from the Journal of Experimental Biology.

Unfortunately for the octopus, the crab was in fact not tasty nor real.

Hopefully Pronk is working up a new test so octopuses can tell us if it's worth it to fork out extra cash for a 240 hertz set, or if we're better off saving with a 120 hertz model.

STYLISTIC Q702

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.
