This stroking finger device mimics the action of a person stroking his/her finger across your skin. I felt that it was apt considering how often we use our fingers to navigate computer screens via mouse or touchpad.
The finger attachment is joined with a loose hinge that enables it to glide across the skin smoothly and also move further than what would have been possible without the hinge.
The movement can also be set to automatic and its speed can be adjusted.
