Fidget is a set of tools especially designed for adults with concentration problems caused by medical, cognitive or psychological disorders, such as AD(H)D, autism related disorders, OCD, emotional trauma, anxieties and many others.
The difficulty to focus forms a challenge in daily life for these adults. For example at the office, at lectures at school or during conversations in a restaurant or at an event. For such occasions, where a more focussed state of mind is necessary, these tools are most suitable.
Because by giving one the opportunity to fidget in several ways, the inner distraction will actually be shifted towards the tools, which eventually creates a higher level of concentration.
In the end that is the core idea of this rather contradictory concept: forming distraction in order to focus.
