A report on a new software that enables eyes to do the typing appears in Wednesday’s edition of the journal Nature. Replacing a keyboard or mouse, eye-scanning-cameras mounted on computers have become necessary tools for people without limbs or those affected with paralysis. The camera tracks the movement of the eye, allowing users to “type” on a virtual keyboard as they look at the screen. And now, researchers from the Cavendish Laboratory at Cambridge University say they have developed software that replaces the standard QWERTY keyboard layout with one that is nearly twice as efficient, more accurate and easier on the eyes. Called Dasher, the prototype program looks into the natural gaze of the eye and makes predictable words and phrases simpler to write. Any off-the-shelf camera capable of scanning eye movement can be used with Dasher, though the person must sit fairly still during the interaction.

  The letters of the alphabet appear in a single column on the right of the screen, with an underline symbol to represent a space. Each letter is framed by a colored box. As the user looks at a particular letter on the right side of the screen and drags it to the left with their eye, another sub-alphabet column begins to emerge inside the box on the right-hand side, along with more letters framed in colored boxes. Dasher is designed to anticipate which letter will be needed, so although the successive sub-alphabet columns are initially very small, the letters or combination of letters that appear are most likely to be used next in that sequence. For example, if a person starts with the letter “h”, the language models in Dasher will bring up “a” “e” “i” “o” and “u” in the sub-alphabet box, along with a few other possible combinations like “ello” to form the word “hello”. Each box has a complete alphabet within it, though the first letters to appear have the highest probability of usage. The letters are then placed together to form a sentence on the left side of the screen.

  Researchers say people will be able to write up to 25 words per minute with Dasher compared to on-screen keyboards, which they say average about 15 words per minute. With a bit of practice, MacKay said, Dasher offers an easier and more satisfying way for disabled people to communicate, providing them with better tools to write e-mail or create word processor files. Mackay said Dasher could work in most languages.

HK’s Family Affair

　The 32nd Hong Kong Art Festival, to be held early next year, will be based on the theme of “family”.

　The art festival, considered to be Asia’s best, began in 1973.

　“We hope that people from Beijing and from all over the world will go to Hong Kong to enjoy the multiple performances in our art festival,”Douglas Gautier, the festival’s management director, said in a press conference in the capital.

　In the 29 days of the festival, which runs from February 8 to March 7, 2004, the audience can choose from 111 performances of 51 programmes staged by 700 foreign performers, 450 local artists and 160 actors from the mainland.

　Programmes vary from classical music, jazz, world music, Western and Peking opera, drama and dance to outdoor spectaculars.

　The programmes include Beethoven’s only opera Fidelio, Shakespeare’s drama Rromeo and Juliet, the ballet Mozartina and African dances, to name just a few.

　The lineup（阵容）includes the English Touring Theatre, Prague Chamber Orchestra, Zurich Ballet, The Spanish National Dance Troupe, as well as Europe Galante, the Petersen Quartet, pianists Angela Hewitt and Marc-Andre Hamelin, and saxophonist Jan Garbarek.

　In an effort to increase attendance, hotels and airlines are offering discount packages along with art festival ticket sales, most of which are at 20% and 30% discounts.

　　For more information, please check:

A chemical important of brain development may play a role in explaining why some people are genetically (由基因决定地) likely to suffer from anxiety and could lead to new treatments, U．S. researchers said.

They said highly anxious rats which were kept had very low levels of a brain chemical called fibroblast growth factor 2 or FGF2, compared with rats that were more relaxed. But when they improved the anxious rats' living conditions—giving them new toys to explore and a bigger cage to live in—levels of this brain chemical increased and they became less anxious.

“The levels of this brain chemical increased in response to the experiences that the rats were exposed to. It also decreased their anxiety.”Javier Perez of the University o f Michigan said in a telephone interview. “It made them behave the same way as the rats that were relaxed，”he said.

In a former study of people who were severely depressed before they died, the team found the gene that makes FGF2 was producing very low levels of the growth factor, which is known primarily for organizing the brain during development and repairing it after injury.

Perez thinks the brain chemical may be a marker for genetic vulnerability (脆弱性) to anxiety and depression. But it can also respond to changes in the environment in a positive way, possibly by preserving new brain cells.

While both the calm and anxious rats produced the same number of new brain cells, these cells were less likely to survive in the high－anxiety rats, the team found. Giving the rats better living conditions or injecting them with FGF2 helped improve cell survival.

“This discovery may pave the way for new, more specific treatments for anxiety that will not be based on sedation(药物镇静), but will instead fight the real cause of the disease，” Dr. Pier Vincenzo Piazza from France said in a statement.
