An augmented-reality (增强现实的) helmet that gives cyclists a 360-degree view of the road could help prevent accidents.
Unlike cars, bicycles don't come with rear view mirrors (后视镜), which is why British product design firm DCA created the Optic helmet. The helmet has front and rear cameras and a drop-down visor (面罩) that can display road conditions in real-time from the rear camera onto a rider's field of view. The visor can show warnings. If a vehicle is overtaking (超过) the rider, it can warn the rider by combining data from the cameras on the front and back of the helmet. In addition, the Optic helmet can provide GPS navigation information for riders who want to track their performance. The design is now just a concept, but it won the “Best of the Best” Red Dot Design Award recently.
Richard Price, a designer at DCA and the brains behind the project, said the helmet is aimed at reducing cycling accidents. Because the helmet is just a concept design, some of the details have yet to be decided, such as the exact method for projecting video onto the visor. However, Price said Google Glass has already shown that this is practical. The Optic helmet will be able to connect to a smartphone via Bluetooth to allow maps and routing information to be updated, but actual navigation will be carried out by the helmet using its onboard (自身携带的) GPS unit. It can be controlled either by a touchpad next to the visor or by using gestures picked up by the front camera.
“Users can order what is shown in the visor to suit their needs and to make sure the display doesn't distract them.” Price said. Since the designs were made public, Price said the design firm has received plenty of positive feedback from cyclists and cycling companies. But actually, putting the device into production will require lots of money, so it is unclear when or if the helmet will be available to consumers.

【推荐1】Who says inventions are only made by grown-ups and professionals? Over the years, children have also succeeded in making their useful contributions to the world. Here are a few inventions that came to life from the minds of young children.
Hero Helmet
Seven-year-old Samuel Meyer's invention is aimed at stopping people from riding their bikes or skateboards without using a helmet. The Hero Helmet features an inbuilt remote that controls a lock on the wheels which unlocks when the Helmet is being worn by the rider. Samuel says: no helmet, no bike.
Robotic Earthworm
The first thought that comes to mind is, why a robotic earthworm? Well, ten-year-old David Cohen had some useful applications in mind. He believed it could be used to find victims after a flood, earthquake or fire. The robot could get into small and dangerous places where search dogs and humans could not go.
B. E. A. C. O. N.
Fifteen-year-old Hannah Herbst's invention, which stands for Bringing Electricity Access to Countries through Ocean Energy, was inspired by her pen pal who lives in Ethiopia and did not have access to lights. So she came up with B. E. A. C. O. N, which absorbs energy directly from ocean waves. Her invention won the “Discovery Education 3M Young Scientist Challenge” in 2015 and other numerous awards.
Portable Wheelchair Controller
At only eight years old, Amelia Fox created the invention to help lift people in and out of their wheelchair. This invention was not just born out of the desire to create something. Amelia developed this controller for her brother, who had just got hip surgery and needed the wheelchair to move around.

【推荐2】A new study has shown how computers and robots powered by artificial intelligence (AI) can read human eye movements to “read” human personalities.
The eyes are the windows to the soul. And if so, computers and robots powered by complex artificial intelligence algorithms (算法) may soon have the ability to peer into your soul. That is the result of a new study on the connection between eye movements and personality, conducted by neuroscience researchers.
“Eye movements during an everyday task predict aspects of our personality,” wrote the researchers, led by University of South Australia neuroscientist Tobias Loetscher, whose team follows 42 study subjects recording their eye movements, then determines their personality characteristics.
The researchers fed the data into their AI algorithms and found that computers running the algorithms were able to record human eye movements and immediately determine a person’s major personality characteristics , such as “neuroticism, extraversion (外向), agreeableness, conscientiousness, as well as perceptual (感知的) curiosity”, the scientists wrote.
“The new findings could improve the way human beings interact with their computers and other high-tech devices, even robots, allowing for more natural and realistic social interactions with machines,” Loetscher said.
“People are always looking for improved, personalized services. Today’s robots and computers are not socially aware, so they cannot adjust to non-verbal information,” Loetscher said in a statement quoted by Indian Express. “This research provides opportunities to develop robots and computers so that they can become more natural, and better at interpreting human social signals.”
The study revealed previously undiscovered relations between specific personality characteristics and specific eye movement tendencies, according to a summary in Britain’s Daily Mail newspaper.

【推荐3】Distancing during the COVID-19 pandemic has made both physical and social connections a touch more difficult to maintain. For Stanford University student Millie Salvato, being apart from her friend on the opposite coast has proved challenging. Sometimes a text or video call is not enough, and people in Salvato’s situation often long for a way to send a comforting hug from afar. In a new study detailed in IEEE Transactions on Haptics, she and her colleagues demonstrated a wearable sleeve that can simulate (模拟) human touch and convey social messages sent electronically.
Salvato and her team measured how 37 participants expressed social messages in different situations. In each test, one person wore a pressure-sensing device on an arm, and another touched it to respond to six different scenes: attention seeking, gratitude, happiness, calming, love and sadness. After collecting 661 touch movements, Salvato and her colleagues mapped the location and pressure of each. Next, they used a machine-learning algorithm (算法) to select the movements that were most reliable part of each response. Finally, they programmed a wearable sleeve to simulate these movements using eight built-in disks that vibrate when electronically signaled. “The instant it received signals, I could feel the touch and identify its intended meaning.” One participant reported.
Even with no training, the participants correctly matched the simulated touches to the six scenes 45 percent of the time. For comparison, a previous study found participants could match scenes for touches from real human hands 55 percent of the time.
Gerling, a touch researcher at Harvard who was not involved in the study, said the invention was really surprising. But the study was small and needs to cover far larger groups of people to determine exactly which are the most desirable responses. Besides, he believes the sleeve surely will enjoy great popularity once launched on the market.

【推荐3】At the beginning of the century there was a big farm called Hollywood Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places in the world. From the 1910s to the 1950s Hollywood was the film center of the world. Every family knew the names of its film stars — Charlie Chaplin, Grela Garbo，Bergman and hundreds more.
The reason why people went to Hollywood to make films was the sun. At first people made films in New York on the east coast of the United States. But then they heard about Los Angeles where there are 350 days of sun every year. As they made all the films by sunlight, the west coast was a much better place to work. Also near Hollywood you can find mountains and sea and desert. They did not have to travel far to make any kind of film.
When TV became popular, Hollywood started making films for television. Then in the 1970s they discovered people still went to the cinema to see big expensive films. After twenty years they are still making films in Hollywood and people watch them all over the world.
