Hand to hand touch causes most of Annie's visions, but she is always wearing protective gloves.
In the scene where the Hulk rescues a man from a hospital fire, the sound microphone can be clearly seen while the hospital staff is trying to extinguish the fire.
Annie was half asleep in the hospital waiting room and about to spill her coffee when a mere touch of her finger (albeit from David) makes her fully wide awake, lucid & sitting upright.
