To the uninitiated, choosing the right emoji for your instagram post can be a daunting task. Knowing just when to unleash a unicorn, or play it safe with a sad face can be bewildering - but now, a web app has come to the rescue. Emojini will do the work for you by suggesting three emojis that best describe the picture, based on its content. Emojini will do the work for you by suggesting three emojis that best describe the picture, based on its content. The web-based tool uses learning algorithms and knowledge of imagery to guess the most fitting emojis for the image you uploaded.

The ability of computers to recognise faces, text and objects has opened up a range of new technologies from smart CCTV to self-driving cars. But the machines still have some way to go before they will be able to rival human eyes. Researchers have shown that when it comes to spotting detail, we still have the edge that may prevent computers from taking over from us entirely. Scientists have found that despite great leaps in artificial intelligence and learning, computer vision is still no match for human eyes when it comes to recognising objects from a tiny part of an image. The pictures above are some of the examples used in the study - are you able to identify the objects in the images above?

The next time you call room service for extra towels, your order may be delivered by a robot. It might not be able to change your sheets, but Savioke's Relay hospitality robot can bring everything from toothpaste to Starbucks, and it uses Wi-Fi and 3D cameras to navigate. The robot is already being used by some hotels in the US, and with recent funding of $15 million, autonomous butlers could soon become a lot more popular. The next time you call room service for a new tube of toothpaste, your order may be delivered by a robot. It might not be able to change your sheets, but Savioke's Relay hospitality robot can bring everything from clean towels to Starbucks, and it uses Wi-Fi and 3D cameras to navigate Each of the Relay robots stands roughly three feet tall.

Pepper, the Japanese humanoid robot's resume already includes helping out in financial institutions, car companies, food and beverage firms - and now it can add cell phone retail. Softbank announced its plans to open a pop-up mobile phone shop that is entirely staffed with the four foot-tall robots. Since these humanoids have the ability to read emotions and formulate accurate responses, the firm believes it will prove to be a successful selling machine. Softbank announced its plans to open a pop-up mobile phone shop that is entirely staffed with the four foot-tall robots. 'I don't know how this will turn out, but it should be a quite interesting experiment,' said SoftBank director Ken Miyauchi during a two-day exhibition called Pepper World.

The race to create robots that look, act and work like humans could see unemployment soar, welfare costs increase and may eventually bring the global economy to its knees. But it could also lead to the fourth industrial revolution. Experts, including scientists, economists and billionaire businessmen, believe robots will be doing more than 5 million typically human-based jobs within the next five years. And if this prediction comes true, inflation will continue to be slow as wages for the remaining human workforce plummet. Experts, including scientists, economists and billionaire businessmen, believe robots will be doing more than 5 million typically human-based jobs within the next five years.

Microsoft is developing a last-gasp'iPhone killer' in its bid to take on Apple and Google. Its current Windows Phone devices have failed to attract buyers - but the firm thinks it has one last chance at success. The firm hopes its'Surface Phone' could become as popular as the Surface tablet. Its current Windows Phone devices have failed to attract buyers - but Microsoft thinks it has one last chance at success. 'We need some sort of spiritual equivalent on the phone side, that doesn't just feel like a phone for people who love Windows,' Microsoft's CMO Chris Capossela said.

Behind the welcome desk at a Singapore university, a receptionist called Nadine is causing a stir. She has mousy, shoulder-length hair neatly parted to the side, remembers what you talked about last time she saw you and returns your greeting with a friendly hello. But there's something unusual about Nadine - she's the latest in a line of so-called'social robots' that have personalities and emotions of their own. Nadine (pictured left) is the next generation of social robots that may appear in offices and care homes in future. Nadine is touted as the latest in a new generation of robots, capable of conversing with people, adapting their responses and remembering previous conversations.

Looking for tiny facial tics from opponents has been used by poker players for decades as a way to spot a bluff, but now Chinese scientists are using the same technique to develop a lie detector. They have created an online polygraph that uses facial recognition to study minute changes in facial expression, skin colour, temperature and heart rate - all of which could reveal a lie. The machine is also fitted with artificial intelligence to analyse visual and voice data to look for such changes that indicate someone is not being truthful. Scientists in China have developed a polygraph that combines artificial intelligence with facial recognition. It assesses changes in facial expression, skin colour, temperature as well as voice to spot if someone is telling the truth or not.

Xiaoice is Microsoft's latest piece of artificial intelligence. She has a'cute' voice, can instantly comment on weather data and big news events, and now, she has a job on morning TV. The Chinese live program, 'Morning News,' introduced the AI on Tuesday, making Xiaoice the first robot to take on a job of this kind. Her voice sounds more like a human's than any other AI's to date, and Xioice's success now has people questioning the future of their careers. Xiaoice is an artificial intelligence software.

While there are fears robots may rise up to take over the world if artificial intelligence progresses too quickly, some of us may find ourselves simply marrying machines in the future. A leading computer scientist has predicted that as robots become more human-like, people may start turning to them for companionship. His predictions mirror the plot of the hit TV series Humans, where people formed emotional attachments to robots brought in to help out around the home. Robots could soon become intimate companions for humans and some people may even seek to marry them as they become more human-like. Unlike other technology, such as mobile phones and computers, robots will have the ability to interact with us in a far more realistic way.
