IBM’s annual poll of its scientists for ideas they think will come to fruition in the next five years turned up smart phones projecting 3-D images of callers and batteries that recharge with air, Bloomberg says.

By 2015, electronic devices also might begin to use mechanisms like auto-winding wristwatches have rather than batteries, the researchers said.

IBM began asking its scientists for their predictions in 2006 and culling them for five ideas that might become reality in the ensuing five years.

Bloomberg said that the 2010 list includes batteries that would use metals that can recharge on contact with air and software that will use real-time traffic data and algorithms for how traffic behaves to forecast backups for drivers.
