2. The interaction caused by elementary particles that results from the coupling of charge to the electromagnetic field.

When people hold their noses and close their eyes, and have others feed them various foods, their sensory interactions can cause a slice of apple to be indistinguishable from a chunk of raw potato, a piece of steak may taste like cardboard, and without their odors, a cup of cold coffee can be hard to distinguish from a glass of red wine.
Sensory interaction also influences how well people hear, such as those with hearing losses watching a video with captioning have no trouble hearing the words they are seeing, but when the captioning is turned off, they suddenly realize that they need it.
