Definitions

• a wig is a manufactured head covering that is worn to alter ones appearance.
• Wigs are worn by men and women alike and are employed in a number of different applications. From a historical context, aristocrats, royalty, and high-ranking officials have traditionally worn wigs to symbolize status in society. Today, wigs are more often worn to disguise the thinning or loss of hair. For example, cancer patients often employ wigs to cover hair loss resulting from chemotherapy treatment. Wigs also find use in an entertainment context to alter the appearance of actors and performers, hi general, the uses and applications of wigs are as varied as the different styles and configurations available.
• Wig construction generally begins with a foundation or cap to which real or synthetic hair is attached.
• cap, wig cap, and foundation may be used interchangeably to generally refer to the base or support structure for a wig.
• the characteristics of the cap such as size, shape, composition, etc. may vary depending upon the particular application.
• wig caps may be hand or machine made and comprised of a fine mesh net or monofilament material.
• the cap is comprised of a translucent monofilament material that, when worn, allows the natural skin color of the scalp to show through.
• other materials, such as Dermafix may be added to the cap, which when heated by body temperature helps adhere the cap to the scalp.
• wigs are constructed by attaching hair to the cap.
• the hair may be selectively attached to the cap to match the needs of the end user, e.g., cover thinning or balding areas, deliver desired entertainment effect, etc.
• Hair characteristics such as texture, quality, color, length, etc. may vary depending upon the particular application or construction technique of the wig.
• the hair may be comprised of human hair, synthetic fibers, or animal hair.
• wigs There are generally three types of wigs that are available, stock, semi-custom, and custom made wigs.
• Stock wigs are usually machine made and are not necessarily designed for a specific person or application. As such, stock wigs are usually cheaper in cost, which unfortunately usually comes at a substantial sacrifice in the appearance and quality of the wig. Moreover, because stock wigs are made with little or no input from the ultimate user, these wigs are often recognizable when worn.
• stock wigs are constructed using a sewing machine to attach hair to a "weft", which is a long string. Once the hair is sewn to the weft, it is then wrapped around and attached to the cap.
• Semi-custom and custom wigs are capable of providing a more natural look when worn.
• reference to semi-custom and custom wigs may be used interchangeably to refer to wigs that are constructed with a particular application, user group, or person in mind.
• the cap and various characteristics of the hair used to construct the wig such as placement, color, texture, length, etc. may be customized to match a particular application or person.
• wig construction is a tedious, time consuming, laborious, and consequently expensive process. This is especially true for custom wig construction.
• the cap is usually custom fit to a particular individual's scalp. This frequently involves measuring the individual's scalp and head and matching the ends of the cap to the individual's hairline. Consideration is also given to the desired coverage the wig is intended to provide.
• the cap may be constructed only to cover balding portions of an individual's scalp.
• the cap may be configured to cover the individual's entire scalp.
• the wig is constructed by attaching hair to desired locations on the cap. Hair is attached to the cap using a manual labor-intensive one-by-one process. Wig makers refer to this process as ventilating a wig. Using a needle, each individual hair is fed through the cap, wrapped around itself, and fed back through the cap in a knot tying fashion. The process employed is similar to the 'latch hook' technique used for tying a rug. A typical wig may require the process repeated between 30,000 and 40,000 times. Moreover, the manual process used for tying a wig generally takes between 40 and 60 hours to complete.
• the present invention is directed to overcoming, or at least reducing the effects of, one or more of the problems set forth above.
• the invention of the present disclosure includes methods for constructing wigs wherein an at least one effector attached to a robotic arm of a robot is positioned proximate to a wig cap; and the effector is then operated to fixedly attach an at least one hair to the wig cap.
• Certain other embodiments of the present invention include a method for constructing a wig wherein the three-dimensional position of a wig cap with respect to an at least one effector attached to a robotic arm of a robot is localized and registered with the controller of the robot followed by the controller operating the effector to retrieve the at least one hair from a hair staging area and then fixedly attaching the at least one hair retrieved from the hair staging area to a location on the wig cap specified by a controller of the robot.
• Still another embodiment of the present invention is a method for constructing a wig that includes: registering the three-dimensional position of a wig cap with respect to an at least one effector attached to a robotic arm of a robot with a controller of the robot; co-localizing at least one fiduciary marker affixed to a model with positions on the wig cap; operating the effector to retrieve at least one hair from a hair staging area; and operating the effector to fixedly attach the at least one hair retrieved from the hair staging area to a location on the wig cap in a position specified by its proximity to the co-localized position of the at least one fiduciary marker.
