Fidgeting
Fidgeting is the act of moving about restlessly in a way that is not (socially recognized as) essential to ongoing tasks or events. Fidgeting may involve playing with one's fingers, hair, or personal objects (e.g. glasses, pens or items of clothing). In this sense, it may be considered twiddling or fiddling. Fidgeting is commonly used as a label for unexplained or subconscious activities and postural movements that people perform while seated or standing idle.
A common act of fidgeting is to bounce one's leg repeatedly. Rings are another common focus of fidgeting; variations include ring spinning, twirling or rolling along a table. Classrooms are sites of fidgeting, and traditionally teachers and students have viewed fidgeting as a sign of diminished attention. Toys have been invented to help with fidgeting. These fidget toys include fidget spinners.
