2、ia. 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 phone would ring. At the end of the day, Mark had accomplished a fractio

3、n 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 weve all become. She watched cubicle (办公室隔间) dwellers as they surfed th

4、e 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 messages or working on a sheet.Marks study also revealed that interruptions a

5、re 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 see; if a mobile phone call breaks through, it might be the call that save

6、s your hide.For some computer engineers and academics, this realization has begun to raise an attractive possibility: Perhaps we can find an ideal middle ground. If high-tech work distractions are inevitable, maybe we can re-engineer them so we receive all of their benefits but few of their downside

7、s.BThe Birth of Multitasking/BThe 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 if someone spoke to a telegraph operator while he was keying a message,

8、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 (驶舱) for fighter pilots were carefully designed so that each dial and meter

9、 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 simply working on one program for hours at a time, a computer user works o

10、n 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 fighter pilots.BEffect of Multitasking: Computer-affected Behavior/BInformation

11、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 possibilities between these two poles.The result is something like “continuous

12、 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. But what happens when you take that to the extreme? You get overwhelmed. S

13、anity 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 computers affect human behavior. She took 39 office workers and installed software on their computers that would record every mouse cl

14、ick. She discovered that computer users were as restless as hummingbirds. 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 another.Why constant shifting? In part it was because of the way computers

15、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 interrupted, it takes just over 23 minutes to cycle back to the original tas

16、k. 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 confusion they bring to our short-term memory.BWays to Cope with Interruptions

17、/BWhen 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 working on (“Test DAs PC, Waiting for AL. “). Then they would place them dir

18、ectly 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 also noticed many Microsoft people attached three monitors to their computers

19、. 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 email program went off, they just peek to the left to see the message.The work

20、ers said this arrangement made them feel calmer. But did more screen area actually help with cognition? To find out, Czerwinski had 15 volunteers sit in front of a regular size 38 cm monitor and complete a variety of tasks designed to challenge their concentration a web search, some cutting and past

21、ing, and memorizing phone numbers. Then the volunteers repeated the tasks using a computer with a massive 105 cm screen.On the bigger screen, some people completed the tasks as much as 44% more quickly. In two decades of research, Czerwinski had never seen a single change to a computer system so sig

22、nificantly improve a users productivity. The clearer your screen, the calmer your mind.BLooking for Better Interruptions/BMark compared the way people work when sitting in cubicles with how they work when theyre at different locations and interact online. She discovered people working in cubicles su

23、ffer 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 talk and interrupt you accordingly.Why dont computers work this way? Instead of

24、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 automated reasoning systems equipped with artificial intelligence that observes a com
