I think the idea of a "thin AIM field" surrounding him is actually much stronger/more concentrated than most espers; it's only through touching this AIM dispersion field to objects that he can manipulate matter, as opposed to espers like Misaka who can launch projectiles almost indiscriminately.

This seems to be stately less directly, and it's mostly inferred by the fact that Kamijou and Kihara Amata in Volumes 3 and 13 respectively were able to disperse/abuse the power only upon making contact with Accelerator's skin, or rather, the AIM membrane surrounding his skin.
