It’s easy to blame an achy neck and stiff shoulder on bad posture. But on many desks, experts agree, the quiet culprit is your mouse.
“There are a lot of delicate body parts involved in mousing,” explains Cameron Stiehl, a San Francisco-based ergonomic assessment specialist. “When you’re at the computer for hours at a time, having a mouse that doesn’t fit properly or is positioned incorrectly can cause soft-tissue injuries in the fingers, wrists, hands, elbows and even in the shoulder.” Countless ergonomic mouse models promise improvement. If you’re ready for a level up, here are four mice that will give you a hand.
1 | Semi-vertical mice like the Logitech MX Master 3S have a 30 to 45-degree slant, which can help reduce stress on the forearm muscles. It can help relieve discomfort from epicondylitis (or ‘tennis elbow’) or help a sore wrist. At 141 grams, the MX Master 3S is a bit heavy but is designed to be especially responsive so that you needn’t move it too much. You can also custom-program the functions of the mouse’s seven buttons and two scroll wheels, letting you avoid certain repetitive motions that can cause injuries. $100, Logitech. com |
2 | Look past their uncanny resemblance to Kubrick’s HAL 9000. Trackball mice can be particularly helpful for treating shoulder discomfort by limiting most of your mousing movement to the fingers and wrist. For the most natural motion, Stiehl suggests the Kensington Orbit Trackball. It has both the namespace feature for moving your cursor with little effort and a ring-style scroll wheel encircling it. Unlike traditional scrollers, you use it like a dial. This, Stiehl says, makes the mouse “especially good for people who have issues like trigger finger” (when bending your digits causes them to painfully click and pop). The Orbit also takes the ergonomics a step further, with an included, detachable wrist rest. $50, Kensington. com |
3 | A vertical mouse lets you position your hand not flat but tilted sideways as if you’re shaking hands with the device. This position, reduces wrist and forearm movement and can be soothing. The Logitech Lift version’s small footprint and light weight (125 grams) make it a good fit for small hands. “It’s not a long vertical, so I think it can be very comfortable if it fits the hand,” said Stiehl. Six buttons allow for control customization, and it comes in three colors (including a very cute rose), and is made of mostly recycled material. $70, Logitech. com |
4 | Working away from your desk doesn’t mean you can’t cast an eye toward ergonomics. The Lenovo Go Wireless Vertical Mouse is a compact vertical mouse, powered by a single replaceable AA battery, which the manufacture r promises will last a year. It also features a handsome cork thumb divot. But the selling point is its smaller footprint, which makes it easy to pack with your laptop. $50, Lenovo. com |

【推荐3】There are many famous museums throughout the world where people can enjoy art. Washington D.C. has the National Gallery of Art (美术馆); Paris has the Louvre; London, the British Museum. Florida International University (FIU) in Miami also shows art for people to see. And it does so without a building, or even a wall for its drawings and paintings.
FIU has opened what it says is the first computer art museum in the United States. You don’t have to visit the University to see the art. You just need a computer linked to a telephone.
You can call the telephone number of a University computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically (采用电子手段) by artists in their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings.
Robert Shostak is director of the new computer museum. He says he started the museum because computer artists had no place to show their work.
A computer artist could only record his pictures electronically and send the records, or floppy discs (软盘), to others to see on their computers. He could also put his pictures on paper. But to print good pictures in paper, the computer artist needed an expensive laser(激光) printer.
Robert Shostak says the electronic museum is mostly for art or computer students at schools and universities. Many of the pictures in the museum are made by students. Mr. Shostak says the FIU museum will make computer art more fun for computer artists because more people can see it. He says artists will enjoy their work much more if they have an audience. And the great number of home computers in America could mean a huge audience for the electronic museum.

【推荐1】A handful of stencils (模板) and three pens sound like materials for a child’s art project. But researchers have now used these tools to draw functional health monitors directly on human skin.
Wearable sensor technology, which helps doctors check a variety of health indicators, has in recent years advanced from heavy equipment to flexible patches (贴片). These sensors can be expensive, however. They also tend to follow skin imperfectly, making them sensitive to the wearer’s move. Researchers say that a new drawn-on-skin electronics system could offer a solution to both problems.
A team led by biomedical engineer Faheem Ershad of the University of Houston first developed a conductive ink that is safe to use on human skin. The researchers loaded the ink into ballpoint pens, then placed a stencil made of tape and film on a volunteer and followed within it to draw the simple circuit (电路) diagram. Within five minutes the ink dried to create a working sensor. The researchers then taped on a standard electrical line to provide power and send data to a computer.
Using just this type of ink, the team measured skin hydration (含水量) and the electrical activity of heart and skeletal muscles. Because the sensor stuck perfectly to the skin, wearers could walk around without jarring it and thus reducing data quality. The ink didn’t take in sweat and was easily removed with a wet paper towel and soap.
For more advanced equipment, Ershad’s team used two additional inks: one served as a semiconductor, and the other acted as an object to prevent electricity. Drawing different layers (层) with each ink, the researchers made temperature and strain (应变) sensors on a sheet of skin-like object, “The authors already presented many very attractive applications,” says Zheng Yan, a biomedical engineer at the University of Missouri. Yan and his colleagues have developed similar technology using pencils and paper, but their method is limited to passive conductors that cannot introduce energy into a circuit. Ershad says that he hopes to create high-tech sensors to discover health indicators ranging from elements in sweat to the brain’s electrical activity.
The researchers plan to eventually make their sensors truly wireless by combining more advanced ink-based circuits. After that achievement, they say, people could use affordable sets of stencils and pens to carefully watch their own health at home.

【推荐2】“Changing the world” might seem like an unrealistic goal. When faced with huge problems such as air pollution or energy shortages, where do you start? Gogoro believes you start with a scooter.
Proof of concept In 2015, Gogoro broke onto the scene by releasing an electric scooter called the Smart-scooter. Unlike most electric scooters. This one wouldn’t need to plugged in to recharge. Instead, users would stop by GoStations to exchange drained batteries for fully charged ones. Gogoro was taking a risk. If people were not happy with the system of changing batteries the whole project could fail. They didn’t need to worry, though. Only one year later Gogoro sold their 10,000th Smart-scooter! |
Setting the bar Fast forward to 2019 and the release of the Series 3 Smart-scooter. Gogoro scooters are as popular and revolutionary as ever. Their bright colors are chosen by Beatrice Santiccioli, a famous color designer who helped shape major brands like Apple, Nike and Swatch. In addition to the scooters’ bright colors, plenty of cool accessories (配件) are available so you can make your scooter your own. But most important of all, Gogoro continues to pave the way toward a future of responsible energy consumption. |
Looking forward Multiple cities and countries have committed to making their transportation all-electric in the coming years, and Gogoro is helping make the possible. Ordered a package? Companies like DHL and Taiwan Post now have fleets of Smart-scooters to make deliveries. Need a ride? Unlock a Gogoro in Berlin, Paris or Madrid, thanks to scooter sharing services. The Smart-scooters is definitely ingenious, but there’s more. “At Gogoro, I think the essential thing is that we want to change how people use energy. And the Smart-scooters is only the beginning.” says Horace Luke, Gogoro co-founder and CEO. This is where the GoStation comes in. |

【推荐3】Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie — all without other people hearing the sound and without headphones.
That is the possibility presented by “sound beaming”, a new technology from Noveto Systems, an Israeli company. On Friday, the company introduced a desktop device that sends sound directly to a listener without the need for headphones or a special receiver.
Noveto Systems gave The Associated Press (AP) a chance to test its SoundBeamer 1.0 before its introduction. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie.The sound seems so close that it feels like it is inside your ears while also in front, above and behind them.
Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D sensing module that finds and follows the ear position of the listener. It sends ultrasonic waves (超声波) to create sound pockets by the user’s ears. The 3-D method creates sound on all sides of the listener, therefore the listeners feel completely transported into the scene.
By changing a setting, the sound can follow a listener around when he moves his head. It is also possible to move out of the sound beam's path and hear nothing at all.
While the idea of sound beaming is not new, Noveto was the first to launch the technology.
According to the chief executive officer Christophe Ramstein, a “smaller” version of the device will be ready for release to consumers next year.

【推荐3】If students will arrive at UT Dallas (the University of Texas at Dallas) after the first day of classes, the ISSO (International Students and Scholars Office) strongly suggests they put off their admission. It’s our experience that late-arriving students have a stressful time settling in and meeting all the pre-registration requirements, such as TB Test (肺结核检查), orientations (入学培训), housing and so on. The inability to meet all these requirements may harm a student’s F-1 or J-1 visa status.
Departmental Late Arrival Letter
UT Dallas academic departments have the freedom and authority to write a late arrival letter on a student’s behalf. Departments may only offer this letter if they are willing to make a statement to CBP (Customs and Border Protection), showing that they will ensure that the late-arriving student will be able to meet all university and immigration requirements despite the late arrival.
Approval or denial of late arrival will be based on the individual worthiness of the request. The letter should be addressed to CBP and sent directly to the student from the academic department.
In general, scanned and printed images will be accepted by CBP. The letter should state:
◎ How late the department is willing to let the student start the semester. This must be a specific date.
◎ That the student will be able to enroll full-time in the academic program and make normal academic progress despite the late arrival.
The letter will not guarantee entry into the US; it simply reduces the possibility that late-arriving students will be turned away at the US Port of Entry.
If Entering Late:
Email the following areas the arrival date as soon as possible:
1. Intercultural Programs (ICPrograms@utdallas.edu) to schedule an International Student Orientation.
2. The Student Health Centre (Healthcen @utdallas. edu) to schedule a TB Test.
3. Academic department to communicate about late registration.
Consequences of late arrival:
◎ Late registration for courses
◎ Limited class availability
◎ Late registration fees
Late-arriving students are required to keep full-time enrollment throughout the semester. The ISSO will not approve reduced course loads due to the late arrival.
