Abstract
A stylus brush for creating paintbrush-like digital effects using a digitizer. The stylus brush includes sensing filaments. The sensing filaments include a conductor extending the length of the filament, wherein the conductor transmits light or current along the length of the filament; a cladding or insulator juxtaposed against the conductor; and a means for changing a light or electrical property passing through the conductor when the filament bends along the length as compared to the light or electrical property of the filament in a nonbent condition, wherein the filament has a width not more than 1 mm and length not more than 10 cm.
Claims21
A filament for a stylus brush, comprising:
- a transmission core extending the length of the filament, wherein the transmission core transmits light or current along the length of the filament;
- a cladding or insulator juxtaposed against the transmission core;
- and
- a means for changing a light or electrical property passing through the transmission core when the filament bends along the length as compared to the light or electrical property of the filament in a nonbent condition, wherein the filament has a width not more than 1 mm and length not more than 10 cm.
A stylus brush for creating images on a workstation surface, comprising:
- a plurality of brush filaments arranged into a brush head at an end of the stylus brush, and
- at least one of the plurality of brush filaments is a filament sensor comprising:
- a transmission core extending the length of the filament, wherein the transmission core transmits light or current along the length of the filament;
- a cladding or insulator juxtaposed against the transmission core;
- and
- a means for changing a light or electrical property passing through the transmission core when the filament bends along the length as compared to the light or electrical property of the filament in a nonbent condition.
A method of sensing bending of filaments of a stylus brush, comprising:
- providing at least one filament sensor in a brush head, the filament including:
- a transmission core extending the length of the filament, wherein the transmission core transmits light or current along the length of the filament;
- a cladding or insulator juxtaposed against the transmission core;
- and
- a means for changing a light or electrical property passing through the transmission core when the filament bends along the length as compared to the light or electrical property of the filament in a nonbent condition, wherein the filament has a width not more than 1 mm and length not more than 10 cm.
