Siemens has shown a prototype solution for improving text entry on the SX1. When activated, a QWERTY keyboard is drawn by laser in front of the phone. Type as you would on a normal keyboard and the device figures out where your fingers are and what letters they correspond to. The laser components do add to the size of the device, but the size increase is nothing in comparison to those strap on keyboards on the market today. The one drawback is that you have to place the SX1 on a flat and stable surface to use the virtual keyboard— it’s not the most mobile of solutions.
