Disclosed are methods and apparatus for conducting market research and developing product designs. The methods involve generating and presenting, typically electronically, generations of design alternatives to persons participating in the design, selection, or market research exercise. The participants transmit data indicative of their preferences among or between the presented design alternatives. Some of the data is used to conduct a conjoint analysis or non-convergent exercise to investigate the drivers of the preferences of the group or its members, and at least a portion are used to derive follow-on generations of design alternatives or proposals. The follow-on designs are preferably generated through the use of an evolutionary or genetic computer program, influenced by the participants' preferences. The process results in the generation of one or more preferred product forms and information permitting a better understanding of what attributes of the product influence the preferences of the test group members.

A Virtual Design Module (VDM) used in a networked design environment generates manufactured product designs that are near optimal in terms of cost and production cycle time by using design data files containing alternative parts and manufacturers information. Numerous product design alternatives are considered and evaluated in terms of design-manufacturing-parts-supplier feasibility and real-time information on cost and production cycle time for realization. The VDM generates a population of new designs with appropriate board design information to allow for design-manufacturer-supplier decision making and determines the feasibility of each member of the current generation of designs and rejects designs that are not feasible. The VDM triggers Mobile Software Agents (MSA) that obtain data for parts availability, cost, lead time and manufacturer data for manufacturing availability, cost and lead time for each feasible member of the current generation of designs and return the data. In one application for printed circuit board design, the VDM evaluates each member of the current generation of designs by calculating cost, lead-time and value using a J function. The VDM then improves board designs through selection and use of board design modifiers. The process continues until optimized designs are obtained. Optimized board designs are output as results to an operator.

Automated electronic document design systems and methods for appropriately sizing and positioning uploaded user images into predefined image areas in a product design being created in a Web environment. For an image that is not to be cropped when incorporated into the design, the image is sized to fit within the selected image area and positioned in the image area according to a predefined anchor location. The aspect ratio of the original image is maintained. For an image that is available for cropping when incorporated into the design, the image is sized and cropped to create a version of the image that fills the image container.

Electronic document design systems and methods allowing a user engaged in customizing an electronic product to re-crop product images in a manner that is compatible with the product layout. Upon selection of an image area in the product design, the user can choose to re-crop the image currently displayed in the image area or to select and crop a different image to be used in the selected image area. A cropping indicator that can be resized and repositioned is provided to the user. The cropping indicator is automatically sized to have and retain the same height to width ratio as the selected image area. Upon completion of any resizing or repositioning operation, the selected image area of the electronic product is updated to reflect the cropping changes made by the user.

The invention relates to a method and a process of determining individual skin structure and function at a point in time for the purpose of determining and formulating skin care products that remedy the deficiencies observed in the skin. Objective and repeatable dermal biometric instrumentation techniques can be used to measure skin moisture content, sebum content, firmness and elasticity properties, skin thickness, transepidermal water loss, skin pH and to perform a photo analysis of the face with UV and visible light. By customizing the skin care products, the individually added active ingredients can be controlled, the diluents can be modified, dermal penetration rates can be controlled, the surfactant systems can be adjusted, and the stability of the product can be controlled. To prevent the loss of active materials in the product, the skin care product is manufactured for an individual consumer and is only sold in a quantity of a three months supply. Additionally, a variety of ingredients can be combined that a mass produced product cannot contain due to stability/compatibility issues. This invention overcomes the limitations in formulating skin products for the mass market by providing a product designed with objective biometric data and created for the specific clinical condition of an individual's skin.
