By 2015, your mobile phone will project a 3-D image of anyone who calls and your laptop will be powered by kinetic energy. At least that’s what International Business Machines Corp. sees in its crystal ball.

The predictions are part of an annual tradition for the Armonk, New York-based company, which surveys its 3,000 researchers to find five ideas expected to take root in the next five years. IBM, the world’s largest provider of computer services, looks to Silicon Valley for input, gleaning many ideas from its Almaden research center in San Jose, California.

Holographic conversations, projected from mobile phones, lead this year’s list. The predictions also include air- breathing batteries, computer programs that can tell when and where traffic jams will take place, environmental information generated by sensors in cars and phones, and cities powered by the heat thrown off by computer servers.
