IBM，the technology company has released its latest"5in 5"report．The expert think five development will become reality within the next five years．Scientists at IBM and other companies are researching ways to make the predictions come true．
They say people will soon have a way to just think about calling or e-mailing someone in order to make it happen．It's a simple ability to command a system to do something for you without actually doing or saying anything，literally thinking and having something happen as a result that's accurate．Something with really deep capability so that a person，for instance，a quadriplegic，a paraplegic can actually utilize brainwaves to make things happen and basically run their own lives independently．
Another prediction is a way for people to power their homes and offices using energy from activities like walking or running．For example，you can see somebody in the third world who has access to a phone or a smart phone but doesn't have access to the power grid（电力网），and literally a shoe can help gain energy from walking and can charge the battery to enable that person to actually become a connected with the rest of the world．
Passwords could soon become a thing of the past．Some of the most common biometrics used to identify people are fingerprints，face and voice recognition，and iris scans．The iris is the colored part of the eye．Dr．Bernie Myerson says this technology will soon be more widely used by money machines and other devices．
Another prediction is from the experts at EBM：better technology to prevent unwanted e-mail．"The device，as you act upon it，as you eliminate mail，you don't read it，you just look at it and kill it，after a while it learns your habits and works for you as your assistant by eliminating stuff you never wanted anyway，"says Dr．Bernie Myerson．
The last on IBM's 5in 5list is an end to the"digital divide"between those who have technology and those who do not．Dr．Bernie Myerson says，"Think about the digital divide today：the haves and the have-nots，people who are and are not connected．We expect within five years，better than80% coverage of the world's populations by cellular to smartphones．At that point，imagine having，for instance，the ability to speak openly with anybody anywhere，anytime and any language--real time translation．
