當手機成為身體的一部分

你和手機搭檔多少年了？每天使用手機多長時間？你們學校對攜帶手機有何規定？與使用手機相關的發明和研究，你又知道多少？

中小學生帶手機進課堂？不行

In a notice published by the Ministry of Educationin February 2021， elementary and secondary schoolstudents are asked not to bring their cell phonesonto the campus， except when it is approved by theirparents along with a written application form. Instead，establishing public telephones on campus and exploringthe use of electronic student IDs with call functions areencouraged as a way to solve the needs of students andparents’ communication. This is to protect students’eyesight and allow them to concentrate on their studies，as well as preventing addiction to the internet andvideo games， according to the notice. Teachers areasked not to use mobile phones to assign homeworkfor students as well. This decision has been backed bymany netizens in China.

手機雖好，但對學生而言，使用風險也是真的大：損傷視力，讓人沉迷于網絡和游戲且無心學習。為了解決這些問題，教育部“交出了答卷”：禁止中小學生帶手機進校園;確實有需求帶進校園的，在父母同意并附上書面申請后可攜帶，但也不能帶進課堂，需要將手機交由學校統一保管;教師也不得使用手機為學生布置家庭作業。這份“答卷”讓眾多網民給出高分。

關燈玩手機，到底有多傷眼睛？

Staring at a screen continuously for hours on endcauses focusing fatigue. Researchers have found highlevels of looking at a phone or tablet is linked witharound a 30 percent higher risk of short-sightedness，also known as myopia. But when it is combined withexcessive computer use， that risk rises to around 80percent. To avoid this， many eye experts recommendthe “20-20-20 rule”–looking away from your phoneor computer screen every 20 minutes and focusing onan object at least 20ft away for at least 20 seconds.Smartphone blindness happens when people lie on theirside at night， with one eye against the pillow and theother staring at the smartphone screen. While one eyeadjusts to the dark， the other eye gets used to the brightlight of the high-resolution screen.

連續數小時盯著屏幕，你將體驗到聚焦性眼疲勞。研究發現，長時間盯著手機或平板電腦，患近視的風險將增加約30%，若再過度使用電腦，風險將上升到約80%。如果你還愛在關燈后玩手機，那么側躺著的你，會體驗到“智能手機眼盲癥”，因為靠著枕頭的眼睛適應了黑暗環境，而看手機的那只眼睛則適應了屏幕發出的亮光。現在，你知道使用手機的正確方式了嗎？要在明亮的環境里，謹遵“20-20-20規則”，并且秉持“能坐不躺”原則哦！

額頭上貼“第三只眼”，讓你能邊走路邊看手機

An industrial design student Minwook Paenghas created a high-tech third eye that can be affixedto a person’s forehead and look out for obstacles asthey walk， while their real eyes are glued to theirsmartphone. Paeng’s Third eye consists of a translucentplastic case that is fixed directly to the wearer’sforehead with a thin gel pad. Inside this plastic eyeare a small speaker， a gyroscopic sensor and a sonarsensor. When the gyroscope detects when the user’shead is angled down， it opens the eye’s plastic eyelidand the sonar starts to monitor the area in front of theuser. When it detects an obstacle， it warns the wearervia the connected speaker. Paeng said his Third Eyeis the first project that tries to imagine what the futuregenerations of “phono sapiens”may end up looking like.

走路玩手機，很危險，如果能像二郎神一樣擁有第三只眼睛就好了。工業設計專業的學生彭敏旭，就發明了一款高科技產品——“第三只眼”。從表面看，“第三只眼”是一個半透明的塑料盒，用薄膠墊就能貼在額頭上。這只“眼睛”內置有小揚聲器、回轉傳感器和聲波定位傳感器。當你低頭看手機時，回轉傳感器會檢測到，從而開啟塑料眼皮，聲波定位儀接著就會監測前方區域;當傳感器檢測到障礙物時，將通過連接的揚聲器發出警告。“第三只眼”正試著想象未來“手機人類”的面貌。
