Every year mobile phones develop. Imagin

Every year mobile phones develop. Imagining what they will look like and be able to do in 2020 is really a challenge. To help, experts have outlined three major mobile trends that they believe will have become reality by then.
Our phones will be so smart in 10 years’ time that they’ll know everything about our situation and warn us when something needs our attention. This is the top prediction of both Nokia and Google. They predict that our cars and home appliances will be able to communicate with our mobile. For example, fridges will tell your mobile to tell you to pick up milk on the way back from work. While driving, your mobile will suggest that you take a different route because there’s a road accident up ahead.
The second trend is in gesture-based controls. People who know the iPhone’s touch-sensitive screen are already familiar with the technology. It translates hand movements into actions on-screen. But gestural communications will make the phone more convenient to use and may completely replace touchpads. According to industry insiders, the most immediate step forward in gestural technology will be in voice recognition. It’s believed voice recognition technology will speed up communications. It is quicker to speak than type. Eventually, phone screens will disappear.
The third major development will change our understanding of a mobile phone. From a single phone, the mobile will be developed into multi-part devices. It is opposite to the current trend in which mobile phones are combining the functions of cameras, music players and game consoles. The prediction is based on the idea that the world will become more wireless and all these—cameras, music players and game consoles—will be wirelessly connected. Mobile phones won’t need to contain these devices because users will be able to control them wirelessly through their phones.
