In a world where technology is king, hardly does a day go by without the launch of some “world-changing” product in the field of alternate reality.
Many people confuse augmented reality (AR) with virtual reality (VR) and understandably so. Both AR and VR offer alternate or altered reality experiences and as a result, it is easy for users to be attracted and wonder what is real and what is not.
However, AR and VR can be quite different in many ways. The main difference lies in the mode of delivery. Simply put, VR “transports” the user to another world, by “replacing” the real world with a virtual substitute most commonly done through helmets or goggles to completely immerse the gamer in a different reality.
AR, however, does not change the entire landscape of what users see.
VR and AR are both powerful technologies which are still relatively new to many consumers.
| A．VR can be interactive or non-interactive. |
| B．In fact, it adds to reality with digital images. |
| C．In short, at the heart of VR and AR are two very similar technologies. |
| D．However, they have already begun to shake things up in the gaming world. |
| E．It is also getting increasingly difficult to keep up with the “R”s that have come into existence. |
| F．For example, it can make users feel as if they are falling, thereby igniting fear. |
| G．They would see computer made images as an overlay to what they see in real life. |

【推荐1】The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don’t know. By next year, half of the calls we receive will be scams（欺诈）. We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it’s too little, too late. By the time these “solutions” become widely available, scammers will have moved onto cleverer means. In the near future, it’s not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you’re hearing is actually real.
That’s because there are a number of powerful voice manipulation ( 处理 ) and automation technologies that are about to become widely available for anyone to use. At this year’s I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.
These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches（数据侵入）of personal information has led to a situation where scammers can easily learn your mother’s name, and far more. Armed with this knowledge, they’re able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller’s, tricking you into "confirming" your address, mother’s name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.
We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications — using apps like FaceTime or WhatsApp, which can be tied to your identity.
Credibility is hard to earn but easy to lose, and the problem is only going to get harder from here on out.

【推荐2】Everyone has probably seen a movie or two about robots going against man. As a kid it was interesting, but not a reality. But today. when we look at how far scientists have come, it's not just a funny thought but a real possibility.
Honda has already created a robot with eyes, legs, arms and hands and it can act just like a person. There is no end to what a robot could do in the future. Just think what we can do in twenty to thirty years. We're dealing with almost an entire new species of human-like robots that could be cleverer than us. Can we continue to use these robots in a way that they serve us, or will they become so wise that they will want independence?
I am really not sure just how far scientists are going to perfect robots. But once this type of robot is made，they will be able to think, make decisions, sense the movement of others and decide what it wants to do.
A new invention has led to the introduction of a female robot, which was introduced at an entertainment show in Vegas. The robot called Roxy sells for between seven and ten thousand dollars. It is built to accompany females. This female robot companion is called true companion md you can find such robots on the Internet. Robots used to have limited uses, but now they are almost in every field, This has opened the door many dangerous possibilities in the future.

【推荐3】As life in cities worldwide becomes more expensive, urban designers are using modern technology to help citizens avoid traffic jams, and shorten the time needed for bus waiting and other things. Technology is also used to cut costly waste.
In Santander, a Spanish port city, parking is easy to find. As one car drives away, an underground sensor shows that a parking space is now free. 400 sensors send messages to signs on streets, and GPS devices direct drivers to the nearest available parking spaces, reducing traffic jams. Trash is collected only when the bins are full and bus stop signs show exactly when the next bus is coming. The public parks are watered only the soil gets dry. All this is made possible by 20,000 sensors installed on buildings, street posts and even buses. They are part of the “smart city” project, launched by the University of Cantabria seven years ago.
University researchers like Luis Munoz regularly meet with locals to discuss how to make their city even smarter. “They propose when they have ideas and sometimes even develop by themselves. Here, we give them the opportunity to see these ideas happen in real life,” said Munoz. For example, the university helped a woman create an app that outlines the easiest route for walking with a baby stroller. Another provides information to residents about their water consumption and sends an alarm to their phone if there is a leak.
The Santander smart project is attracting the attention of larger cities in Europe and elsewhere that are looking for smart solutions to urban problems.
