Will the world change when humans have personal force fields? Watch
Would such a device, which is fully possible in the near future, change society completely?
Even if this was possible it would require far too much energy to fit on a watch, my phone can't even go half a day of internet browsing without needing to recharge. In any case the only force field research I'm aware of is to stop shockwaves or radiation, they would do nothing to physical attacks or bullets.
