Navigation(导航)in unfamiliar places is a major problem in large cities.Therefore,the popularity of mobile GPS facilities has greatly risen.However,it is sometimes difficult for users to understand where to go.In addition,they have to regularly look at the screen to follow the route,thus increasing risks on the road.

Luckily,preuniversity students from the National Research Nuclear University MEPhI in Moscow have created sneakers that can give directions,count a person's steps and measure the calories burned.The smart sneakers can lead users to their destination.The idea is simple.When moving towards a turn,the right or left shoe vibrates(震动)according to the directions.

“We've developed a facility that goes well with a special mobile app via Bluetooth and receives information about a route.The facility performs all the necessary functions without affecting walking and can be joined to the laces(鞋带)of ordinary sneakers.The user only needs to run the app once,and then puts the phone away and enjoys the walk.In addition to navigation,the system can also keep track of the distance traveled.This information can be found in the mobile app,”said Alexander Pinchuk and Maxim Levkin,the authors of the project.

The team plans to continue developing the project because the smart clothing market is growing every year.According to the creators,it is likely that in a few years,smart sneakers will become popular like smart watches.

This is not the first original project of preuniversity students from the National Research Nuclear University MEPhI Valentin Klimov,deputy director of the Institute of Cyber Intelligent Systems of MEPhI,says,“Our preuniversity students have created rather original projects before.For example,last year,our students developed a useful system for people with poor eyesight and won an international children's competition;then they won the Junior competition and took part in the largest international competition:Intel ISEF.Now these guys are our first year students,and this shows the high level of our applicants.”

From rolling hills to mountain ranges, views make any road trip memorable, but for blind passenger this is part of the experience they miss. Motor company Ford tries to change that. It teamed up with GTB Roma and Ae do Project—to develop a technology that will give those unfortunate passengers away to feel nature’s beauty through their car windows.

The prototype (原型) of the smart car window has a device with an outside-facing camera. With just a press of a button, the system takes a picture of the current view. The colorful picture is then turned into an image with different shades of grey through LED lights, which vibrates (震动) differently. As the finger passes over different regions of the image, its shaking movements provide feedback through the sense of touch to the person using it. The smart window also comes with a voice assistant that uses AI to identify the scene and help the passengers get information on what they’re seeing.

“As the prototype started taking shape, we realized we were giving birth to a completely new language that would give blind people a new chance to visualize and experience traveling,” Federico Russo, one director of GTB Roma, said. “When the idea was at its first stage, we looked for suppliers all around the world to make it come to life.” He believes the technology can be employed not just in cars. “It could be introduced into schools and institutions for blind people as a tool that could be used in multiple ways.”

The technology may show up in a Ford autonomous vehicle. It’s known that the company is testing their technology and future business model and struggling to figure out how an autonomous vehicle gives different passengers the details needed to get from one destination to another. It’s unclear when this technology will be made available. However, the idea of building something for the less advantaged is indeed a kind and influential action.

More than 4,000 people died in car crashes in the United States in 1913. The nation’s roads weren’t built for vehicles that could speed along at 40 miles an hour, and when those machines met at a crowded intersection, there was often confusion. 【小题1】 few drivers paid attention.

【小题2】. Borrowing the red and green signals long used by railroads, and, tapping into the electricity that ran through the trolley lines. Hoge created the stoplight. 【小题3】

Hoge’s light made the first public appearance in 1914. Drivers approaching the intersection now saw two lights hung above it. A policeman sitting in a booth on the sidewalk controlled the signals with a switch（开关）. “【小题4】, as it makes for greater safety, speeds up traffic, and largely controls pedestrians in their movements across the street,” the city’s public safety director wrote after a year of operation. Six years later, we had William Potts, a police officer who had studied electrical engineering, to thank for the yellow light, but he could not patent his invention.

By 1930, all major American cities and many small towns had at least one electric traffic signal, and the innovation was spreading around the world. 【小题5】
