Taiwan researchers design webcam antenna for fast scans

The notebook PC-mounted tool captures library documents with minimal human effort

A pair of Taiwan researchers have designed what they believe to be the first webcam-equipped antenna that can be unfolded from a laptop PC for quick scans of lengthy documents.

Graduate students Wang Chi and Lai Chih-wei at the National Taipei University of Technology spent a month designing the 20-centimeter long, 1.5-centimeter thick steel antenna with the goal of capturing massive library files that cannot be taken home.

Users hold the webcam over a page facing up on a table next to the laptop, which takes a picture. They can then flip quickly to the document’s next page, sparing the time required to scan the same document by placing each page face down on a machine and pressing a button.

Users can buy external webcams with a USB cable to do the same job, but Wang's and Lai's design is meant to come already attached to the laptop.

And laptop users seldom carry scanners around.

"Because in our personal lives we encounter this kind of problem, we set about finding a way to solve it," Wang said in an interview.

Webcam images look as sharp as scans, he said, and they can be looked at anytime, anywhere. Webcams are used more often for PC-to-PC video-conferencing and occasionally linked to cyber-spying accusations.

The invention won a silver prize in a notebook PC design contest sponsored by Taiwan-based Elitegroup Computer Systems. Judges found that the tool gave "fresh value" to an existing PC, the company's industrial design technology department said in a statement.

"Although we currently have no further plan to implement it, it could be a good concept for reference when we develop a new product," the statement said.

Now the inventors are talking to a teacher in their department about how to mass produce the tool.

A small order could be costly, Wang estimated, but the unit price would fall if the tool were mass manufactured. He declined to name possible prices.

"We of course hope that our design can somehow be marketed," Wang said.

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.
