9. What is browsing?

Browsing is a matter of visual scanning, "where the person's body or eyes move smoothly at will". If we imagine literally doing what this clause says, then we visualize the proverbial fur-trapper or scout in the woods or on the edge of a meadow, shading his eyes with a flattened hand held perpendicularly out from the forehead and rotating the head from one side to the other in a smooth scan of the environment. (source: What is browsing— really?A model drawing from behavioural science research, http://informationr.net/ir/12-4/paper330.html). browsing can be seen to contain four elements:
1. glimpsing a field of vision;
2. selecting or sampling a physical or representational object from the field;
3. examining the object; and
4. physically or conceptually acquiring the examined object, or abandoning it.
