3、00, Gloria Mark was hired as a professor at the University of California. She would arrive at her desk in the morning, full of energy and ready to tackle her to-do list. No sooner had she started one task than a colleague would e-mail her with an urgent request; when she went to work on that, the ph

4、one would ring. At the end of the day, Mark had accomplished a fraction of what she set out to do. Lots of people complain that office multitasking drives them nuts. But Mark studies how high-tech devices affect our behavior, so she was able to do more than complain, she set out to measure how nuts

5、weve all become. She watched cubicle (办公室隔间 ) dwellers as they surfed the chaos of modern office life and found each employee spent only ten-and-a-half minutes on any given project before being interrupted. Each short project was itself fragmented into three- minute tasks, like answering e-mail mess

6、ages or working on a sheet. Marks study also revealed that interruptions are often crucial to office work. The high-tech workers admitted that many of their daily distractions were essential to their jobs. When someone forwards you an urgent e-mail message, its often something you really do need to

7、see; if a mobile phone call breaks through, it might be the call that saves your hide. For some computer engineers and academics, this realization has begun raise an attractive possibility: perhaps we can find an ideal middle ground. If high-tech work distractions are inevitable, maybe we can re-eng

8、ineer them so we receive all of their benefits but few of their downsides. The Birth of Multitasking The science of interruptions began more than 100 years ago with the emergence of telegraph operators-the first high-stress, time-sensitive information-technology jobs. Psychologists discovered that i

9、f someone spoke to a telegraph operator while he was keying a message, the operator was more likely to make errors. Later, psychologists determined that whenever workers needed to focus on a job that required the monitoring of data, presentation was all important. Using this knowledge, cockpits (驾驶舱

10、 ) for fighter pilots were carefully designed so that each dial and meter could be read with just a glance. Still, such issues seemed remote from the lives of everyday workers. Then, in the 1990s, computers began to experience a rapid increase in speed and power. “Multitasking“ was born; instead of

11、simply working on one program for hours at a time, a computer user works on several simultaneously. Office workers now stare at computer screens of overwhelming complexity, as they juggle (操纵 ) messages, text documents, PowerPoint presentations and Web browsers. In the modern office we are all fight

12、er pilots. Effect of Multitasking: Computer-affected Behavior Information is no longer a scarce resource attention is. 20 years ago, an office worker had two types of communication technology: a phone, which required an instant answer, and postal mail, which took days. Now people have dozens of poss

13、ibilities between these two poles. The result is something like “continuous partial attention“, which makes us so busy keeping an eye on everything that we never fully focus on anything. This can actually be a positive feeling, inasmuch as the constant email dinging makes us feel needed and desired.

14、 But what happens when you take that to the extreme? You get overwhelmed. Sanity lies in danger. In 1997, Microsoft recruited Mary Czerwinski, who once worked in NASAs Human- computer Interaction Lab, to conduct basic research to find out how computer affect human behavior. She took 39 office worker

15、s and installed software on their computers that would record every mouse click. She discovered that computer users were as restless as hummingbird. On average, they juggled eight windows at the same time. More astonishing, they would spend barely 20 seconds looking at one window before flipping to

16、another. Why constant shifting? In part it was because of the way computers are laid out. A computer offers very little visual real estate. A Microsoft Word document can cover almost an entire screen. Once you begin multitasking, a computer desktop quickly becomes buried in windows. When someone is

17、interrupted, it takes just over 23 minutes to cycle back to the original task. Once their work becomes buried beneath a screenful of interruptions, office workers appear to forget what tasks they were originally pursuing. The central danger of interruptions is not the interruption at all, but the co

18、nfusion they bring to our short-term memory. Ways to Cope with Interruptions When Mark and Czerwinski, working separately, looked at the desks of the people they were studying, they each noticed the same thing: Post-it notes. Workers would write brief reminders of the task they .were supposed to be

19、working on (“Test DAs PC, Waiting for AL. “). Then they would place them directly in their fields of vision, often in a circle around the edge of their computer screens. These piecemeal efforts at coping pointed to ways that our high-tech tools could be engineered to be less distracting. Czerwinski

20、also noticed many Microsoft people attached three monitors to their computers. They placed their applications on different screens-the email on the right side, a Web browser on the right and their main work project in the middle-so that each application was read at a glance. When the ding on their e

21、mail program went off, they just peek to the left to see the message. The workers said this arrangement made them feel calmer. But did more screen area actually help with cognition? To find out, Czerwinski had 1,5 volunteers sit in front of a regular size 38cm monitor and complete a variety of tasks

22、 designed to challenge their concentration-a Web search, some cutting and pasting, and memorizing phone numbers. Then the volunteers repeated the tasks using a computer with a massive 105em screen. On the bigger screen, some people completed the tasks as much as 44% more quickly. In two decades of r

23、esearch, Czerwinski had never seen a single change to a computer system so significantly improve a users productivity. The clearer your screen, the calmer your mind. Looking for Better Interruptions Mark compared the way people work when sitting in cubicles with how they work when theyre at differen

24、t locations and interact online. She discovered people working in cubicles suffer more interruptions, but they have better interruptions because their co-workers have a social sense of what theyre doing. When you work next to others, they sense whether youre deeply immersed or relatively free to tal

25、k and interrupt you accordingly. Why dont computers work this way? Instead of alerting us to email messages the instant they arrive, our machines could deliver them at optimum moments, When our brains are relaxed. Eric Horvitz at Microsoft is trying to do precisely that. He has been building automat

26、ed reasoning systems equipped with artificial intelligence that observes a computer users behavior and tries to predict the moment the user will be mentally free and ready to be interrupted. 2 As Marks study indicated, interruption is a highly undesirable feature in high-tech office work, and theref
