## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation under 37 C.F.R. 1.53(b) of U.S. application Ser. No. 10/435,413 filed May 9, 2003, now U.S. Pat. No. 7,168,804, which claims the benefit under 35 U.S.C. 119(e) of U.S. Provisional Application Ser. No. 60/465,327 filed Apr. 24, 2003, which applications are incorporated herein by reference.


BACKGROUND
There are many benefits that can be derived from obtaining consumer-related information, such as ethnographic information, from consumers. Some example uses of consumer-related information include developing new product features and validating new product concepts. Consumer-related information is also valuable in developing new products and determining potential new markets that address consumer preferences. Other benefits include using the information to improve product ergonomics, usability and document consumer routines (among other applications).
One difficulty associated with obtaining information from consumers is that while consumers provide information as to what they know and remember, they are often not aware of some events or they forgot to pass along important information. Researchers typically address this difficulty by video recording consumers using products. The video recordings are studied by researchers to obtain useful data.
A consumer is usually recorded by positioning one or more cameras within an area and having the consumer utilize the product within that area. One drawback with recording consumers in this manner is that the recordings typically fail to provide a perspective from the consumer's point of view. Another potential drawback is that the systems and methods often fail to capture any sounds (e.g., comments made by the consumer) which are associated with the consumer using the product.
Another drawback with conventional consumer recording techniques is that the consumer typically utilizes the product in a fabricated environment instead of an environment where the product is normally used (e.g., a home). Consumers may use products differently in a fabricated environment versus a natural environment. Therefore, recording a consumer in an unnatural environment may result in obtaining less accurate information.
There is a need for a system and/or a method that obtains information from consumers relating to the use of products in a natural environment. The system and method should be able to audibly and visually document a consumer's use of a product from the consumer's perspective to obtain valuable ethnographic information which can be used to develop improved products.
SUMMARY OF THE INVENTION

Recording the use of the product P by the consumer 200 may include recording the consumer 200 shopping for a product.
Some ethnographic information obtained by this system may be used to perform time, effort and/or motion studies on an individual 100/consumer 200.
Researchers can obtain additional information by analyzing a sequence of operations (e.g., task analysis) that are nominally associated with an individual performing an activity, such as using a product. This analysis may be used to enhance a product's usability or to develop brand new products.
Some other forms of ethnographic information that may be acquired include (i) documenting errors or mishaps associated with using a product; (ii) keeping a record of how consumers customize a product and/or the environment when the consumer uses the product; and (iii) observing an individual/consumer's behavior as they use the product.
In some forms, obtaining ethnographic information includes performing studies that examine design changes which have been made based on ethnographic information from earlier studies. This type of ethnographic information is helpful in validating design changes or new product designs.
It should be noted that many different types of analysis may be done using the ethnographic information obtained by the system, including behavioral, psychological, physiological, and user-to product-to environment interaction analysis. Any of these types of analysis may be used to develop improved and/or new products (among other applications).
The method may further include (i) supplying the consumer 200 with the product P; and/or (ii) obtaining information from the consumer 200 relating to recording the use of the product P using the microphone 16 and the camera 14. In addition, recording the use of the product P using the microphone 16 and the camera 14 may include recording the consumer 200 in an environment where the consumer 200 normally uses the product (e.g. a home).
Another method of observing use of a product P by a consumer 200 is described herein with reference to FIGS. 4-6. The method includes affixing a camera 74 to glasses 72 that are adapted to by worn the consumer 200 and recording the use of the product P by the consumer 200 using the camera 74 in a home environment, such as the consumer's home.
The method may further include (i) affixing a microphone 76 to the glasses 72 that are adapted to be worn by the consumer 200; (ii) supplying the consumer 200 with the product P; and (iii) manually and/or automatically adjusting the camera 74 relative to the glasses 72 to modify the view of the consumer 200 using the product P.
In some forms of the method, recording the use of the product P by the consumer 200 using the camera 74 includes obtaining ethnographic information relating to use of the product P by the consumer 200. In addition, affixing the camera 74 to the glasses 72 that are adapted to by worn the consumer 200 may include clipping the camera 74 onto the glasses 72 (see, e.g., camera 74 and glasses 72 in FIG. 9).
In another aspect, a method of observing a consumer shopping is described herein with reference to FIGS. 1-6. The method includes affixing a camera 14 and a microphone 16 to an article 12 worn by an individual 100/consumer 200 (see, e.g., FIG. 1). The method further includes recording the consumer shopping using the microphone 16 and the camera 14.
As shown in FIGS. 2 and 3, the method may further include adjusting a camera 44 relative to the article 42 to modify the view as seen by the camera 44. In addition, affixing a camera 74 to an article worn by a consumer 200 may include affixing a camera 74 to glasses 72 worn by the consumer 200 (see, e.g., FIGS. 4-6).
The method may also include obtaining ethnographic information associated with a consumer shopping for a product. As an example, such ethnographic information may be analyzed to (i) obtain time, effort and/or motion studies associated with handling a product during shopping; (ii) document the portions of a product's packaging the consumer reads; and (iii) observe a consumer's actions as they relate to choosing from multiple products. The insights developed can be used to improve packaging, package graphics and package placement to enhance package visibility, consumer appeal and purchase interest (among other applications).
The vision systems and methods described herein allow researchers to video record individuals engaged in activities, such as consumers using products, within the correct environmental context. Future developments in technology are foreseen in which all components continue to get smaller creating more opportunities to conceal them in glasses or other wearable elements such as hats, ties, buttons, pens, etc. In addition, researchers may be able to communicate with consumers/individuals in order to make adjustments to the method while the consumer/individual is in the process of performing the method.
The operations discussed above with respect to the described methods may be performed in a different order from those described herein. It should be noted that individual and consumer are sometime used interchangeably. In addition, FIGS. 1-6 are representational and are not necessarily drawn to scale. Certain proportions thereof may be exaggerated, while others may be minimized.
While the invention has been described in detail with respect to the specific aspects thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these aspects which fall within the spirit and scope of the present invention, which should be assessed accordingly to that of the appended claims.
