电脑鼠标能跟着人的鼻子走

The computer mouse is no longer so mighty¹. A Canadian engineer has invented a system that enables a computer user to push a cursor across a screen simply by moving his or her nose. He calls his nose-driven mouse a nouse.
　　电脑鼠标不再那么威力无比了。一位加拿大工程师发明了一套系统，可以使电脑用户只需移动鼻子即可让光标在屏幕上任意游走。他把这种用鼻子驱动的鼠标称作“鼻标”。

The inventor, Dmity Gorodnichy, came up with the idea for the nouse while building computer software that would help astronauts operate the Canadarm — a long robotic arm on the U.S. space shuttle. His system employs a Webcam that identifies a computer user's nose from 25 pixels, or points of light. Dmity chose the nose because its position remains² relatively³ constant no matter which way the head is tilted⁴. The system keeps track of the pixels, and the user matches the movements of his or her nose with the progress of the cursor across the monitor.
　　发明者德米蒂·高罗德尼奇关于“鼻标”的创意来自于一次电脑软件的开发，此软件用于协助宇航员操控加拿大机械臂（美国航天飞机上的机器臂）。他的系统借助了一部网络摄像机，可以用25个像素或亮点定位电脑用户的鼻子。德米蒂之所以选择鼻子定位，是因为不论头部如何扭动，鼻子的位置相对保持不变。系统追踪像素移动痕迹，用户挪动鼻子让光标在显示屏上做出相应的操作。

The nouse keeps track of the eyes too. Two blinks are a "double click",  which turns the nouse on or off.
　　眼睛也能定位鼻标。眨两下眼相当于“双击”，可以打开或者关闭鼻标。

The nouse has received mixed reviews from critics. One called it "a singularly pointless waste of technology" destined⁵ for "techno-oblivion".  Another predicted that the device will fail to catch on because it makes users "look silly".
　　评论家对鼻标的评价褒贬不一。有人称它是“不折不扣的、毫无意义的技术浪费”、注定要被“技术遗忘”。还有人则预言它不会受欢迎，因为它令用户显得傻里傻气。

Unfazed by the thumbs-down notices, Dmity has already adapted the nouse for NousePong, a video game, and NousePaint, a drawing program.
　　德米蒂对这些贬损的说法不以为忤，他已经在电视游戏NousePong和绘图软件NousePaint中使用鼻标。

He also predicts that the nouse will appeal to people who have carpal tunnel syndrome- pain, numbness⁶, or tingling⁷ in the hand caused by the excessive repetition of specific motions of the wrist and fingers, such as typing at a computer keyboard. His next plan is to adapt the nouse for use by paralyzed patients in hospitals. With two blinks of the eyes, patients could double-click for help.
　　他还预言鼻标会受到腕管综合症患者（由于手腕和手指过度重复特定动作导致手部疼痛、麻木和刺痛，比如敲击电脑键盘）的欢迎。他的下一个计划是将鼻标应用于医院里瘫痪的患者。病人眨两下眼睛，就可“双击”求助。
