A cleaning kit is included with every WISP ensure the puff tube remains clean. As an alternative, we have developed a special face switch based on fiber optic technology. These switches are actuated whenever the beam of light emitting from the end of the fiber is blocked. The switches mount over the ear and come down alongside the cheek. The positioning of the switch is fully adjustable.
Users click by simply pulling back the corner of their mouth or squinting to break the light beam.
An additional option is a laser pointer which is also mounted over the ear. This can be used to point at things for people who can t use their hands to point. Identifying objects, directing care attendants, and getting someone s attention are common uses of the laser pointer. The laser can be turned on and off directly by the user, but also turns itself off after 20 seconds. Care must be taken not to shine the laser directly in someone else s eyes.
