Abstract
A method for air writing includes creating an airborne field of luminescent particles by using a particle generator connected to a reservoir containing luminescent particles, and tracing a visible path through the field by using a wand to change an intensity of at least some of the airborne particles. The intensity change is effected by causing a chemical reaction to occur at said at least some particles, and may include illumination of dark particles via emission following from light-induced excitation, or quenching of initially illuminated particles. Still other aspects and other features are also described herein.
Claims40
An air writing system, comprising:
- (a) a particle seeding subsystem, including:
- (i) a reservoir of luminescent particles;
- (ii) a sprayer configured to access said luminescent particles in said reservoir to create a buoyant field of said luminescent particles;
- and
- (b) a source of activating agent for changing a luminance of some of said luminescent particles within said buoyant field by causing a chemical reaction;
- (c) a handheld wand for writing in said field, including
- (i) an opening in said wand for outputting at least one of said luminescent particles and said activating agent while said wand is being moved in a spatial pattern by a holder thereof;
- and
- (ii) a user-operable switch for selectively controlling said outputting of said particles.
An air writing system, comprising:
- (a) a particle generator configured to create an airborne field of luminescent particles;
- (b) a source of activating agent for changing a luminance of some of said luminescent particles by causing a chemical reaction;
- and
- (c) a handheld wand for writing in said field, including an opening for outputting a stream of said luminescent particles while said wand is being moved in a spatial manner by an air writer.
An air writing system, comprising:
- (a) means for creating an airborne field of luminescent particles;
- and
- (b) means for changing a visual intensity of at least some of airborne luminescent particles within said field by pointing a wand at said airborne luminescent particles during an air writing operation.
