Imagine looking at a view of mountaintops and wondering about the name of each peak. Suddenly, above each mountaintop, a name appears on the sky. The words are not written in smoke by skywriting planes. The words are actually not in the sky at all. They come from tiny computers in contact lenses (隐形眼镜).
Computers have become smaller and smaller over the decades. The first computers filled houses. Transistors (晶体管) and then chips allowed computers to become small enough to fit on a desktop, then a laptop, and finally a phone. When experimenting with further contraction in size, developers often have to deal with the limits of human eyesight, which control how small the computers can be and still present visible information.
One new solution employs microprojectors (微型投影机) to create a readable display (显示) for tiny computers. These machines project computer information onto any surface. Though an impressive breakthrough, there are potential problems. Such public displays can lead to privacy concerns; most people do not want their information displayed on a wall for everyone to see. Besides, these projectors are extremely expensive, and their screens give users headaches.
Babak Parviz, a researcher at the University of Washington, created another solution: inventing a screen visible only to a person wearing a contact lens. Parviz created a computer in a contact lens that uses the wearer’s field of vision as the display. To create the display, Parviz took ordinary soft contact lenses with a wirelessly controlled system. At some point, Parviz says, it will be possible to connect the lens to a remote personal computer device such as a cellphone or a laptop. By looking in a certain direction, the wearer sends the computer visual information about what he or she sees. The device then uses this information to point out the names of peaks.
These contact lenses are inserted and removed in much the same way as ordinary contact lenses. In addition, the computers in the lenses won’t block the wearer’s sight at all. Although now the computers are not on lenses treating eyesight problems, Parviz hopes that someday the technology will progress to that level.

As Shanghai prepared to introduce mandatory(强制的) garbage sorting on July 1, games and toys that examined fun ways to spread information about the garbage sorting were to encourage younger people to take action.
A 15-second video of a game went on Chinese social media. In the video, players wearing VR(虚拟) headsets saw four different types of trash can in front of them, and had to throw different types of garbage into the right buckets(桶) to get points. Although it was not the only VR game in the place, visitors lined up around the booth to explore it because of the garbage-sorting theme.
“As a Shanghai, I am in great need of this game. Maybe I won’t need to check how to categorize(分类) each piece of garbage on my phone while going through all my garbage every day if I play this game more often, ” said ZhouZhou, a young Shanghai. But some social media users in Shanghai have complained about the difficulty of sorting different types of garbage.
Wu Xia, founder and CEO of VitrellaCore, the company that created the game, said the idea was to provide an interesting way of learning about garbage sorting. “It’s simple and easy to understand. People can practice sorting garbage without actually going through their trash, and it is a more effective method than using paper materials when training volunteers,” Wu said.

Desiree, a 4-year-old girl, was sobbing quietly over her father, Ken, who had died nine months earlier. She was hugging a photograph of her father with her fingers running around his face. “Daddy”, she said softly, “Why won't you come back?”
Instead of gradually adjusting to her father's death, Desiree refused to accept it “Daddy will be home soon,” she'd tell her mother. “He's at work.” When she played with her toy telephone, she pretended she was chatting with her father “I miss you, Daddy,” she'd say. “When will you come back?” Desiree's situation made her mother worried.
Days later, it was Ken's birthday. “How will I send him a card?” Desiree asked her mother “How about if we tie a litter to a balloon.” her mother said, “and send it up to heaven?” Desiree's eyes immediately lit up.
Her mother took her to a store and Desiree picked out a balloon with HAPPY BIRTHDAY above a drawing of The Little Mermaid (美人鱼). Desire and her father had often watched it.
The child's eyes shone as they were on the way to Ken's grave. Then Desiree dictated (口述) a letter to her Dad. “Daddy, Happy birthday, I love you and miss you,” she rattled off (快速说). “I hope you get this and can write to me on my birthday in January.”
Her mother wrote the message and their address on a small piece of paper, which was then wrapped in plastic and tied to the end of the string on the balloon. Finally, Desiree let fly the balloon. For almost an hour, they watched the shining spot of silver grow smaller and smaller till disappear. “Now Dad's going to write back to me,” Desiree said confidently.
Every day since they'd flew the balloon, Desiree had asked her mother, “Do you think Daddy has my balloon yet?” Several weeks passed, and she stopped asking.
Desire's fifth birthday came and later on the afternoon, a package arrived.
