The present invention discloses a tilting controller that measures foot-related human biomechanical data. The tilting controller for measuring foot-related human biomechanical data includes a mechanism having a foot hold on which a rear foot portion is placed, and a control module that tilts the foot hold by controlling the mechanism portion.

A measurement device for shoe fitting evaluation is disclosed. The measurement device for shoe fitting evaluation includes a last insertable into a shoe, a pressure measurement unit configured to measure a wearing pressure on a top surface of a foot of the last, and a gap measurement unit configured to measure a gap between an end portion of the last and an end portion of the shoe. The last includes a main body portion and a variable portion. The variable portion is changeable in its shape, its weight, or its position with respect to the main body portion.

A footbed for use in footwear is provided. The footbed assembly includes a resilient, flexible material (e.g. EVA or PU foam) that extends the entire length of the footbed. a heel plate made from a material that is more rigid (plastic, carbon fiber) than the resilient foam attaches to the flexible material. The shape of the resilient footbed defines a geometry that provides support and comfort to the user by reducing peak pressures, improving cushioning, and enhancing foot support. The resilient foam and heel plate defines the shape of the midfoot R2 and rearfoot R1 of the footbed while the resilient flexible foam continues forward to define the shape of the forefoot R3 region of the footbed.

This invention belongs to measurement methods that can be used in light industry, when measuring the shape and size of the human body parts. Disclosed is a method, over the course of which, based on a series of photographs an image of a flat object of known shape and size is identified on each photograph. The body part area is isolated from the background in the image, and the area of an arbitrary body that does not belong to the projection of the human body part is cut out. Also disclosed is a method for searching an image of a flat object of known shape and size, its projection, and the camera location and orientation, over the course of which the predicted image of the flat object is compared to the real on. Here, the particle dynamics technique is used for isolating a human body part from the image background.

In a shoe fit evaluation system, a dimensional difference calculator calculates a part dimensional difference, which is a difference between a measurement value of a foot part dimension and a last part dimension corresponding to the foot part, by performing a certain adjustment for the part. An evaluation processor calculates a last matching rate based on the part dimensional difference. An outputter outputs information regarding the last matching rate. The dimensional difference calculator calculates the part dimensional difference by performing, as the certain adjustment, subtraction of an allowance for specific stretch properties of each shoe part.

In some embodiments, apparatuses and methods are provided herein useful to providing personalized footwear and/or generating personalized footwear recommendations. In some embodiments, systems and methods for providing personalized footwear may include or employ one or more of a foot shape module, a pathology module, a gait and biomechanics module, and a context module. The foot shape, pathology, gait, biomechanics, and context modules may acquire and analyze data related to foot shape, pathologies, gait, biomechanics, demographics, lifestyle, location, and/or product preferences associated with a user to determine one or more personal attributes associated with the user. In addition, the systems and methods provided herein may include or employ a footwear module to collect and analyze data related to construction, materials, material properties, category, style, and/or aesthetics of footwear products to determine footwear attributes associated with the products. Personal attributes and footwear attributes may be used to provide personalized footwear products and/or recommendations. In other embodiments, systems and methods for providing personalized footwear may include or employ sensors or analysis of previously worn footwear. The sensors may acquire, determine, or transmit data related to certain attributes associated with a user. Personal attributes and footwear attributes may be used to provide personalized footwear products, recommendations, and/or footwear lasts. In addition, the systems and methods provided herein may include or employ repeating certain steps to create a circular method of providing personalized footwear or providing personalized footwear lasts.

A system for choosing an article of footwear provides for capturing an image of a foot in order to obtain a reference sole or morphology, measuring a length of the foot for the application of equalization and calculation constant values, constructing a grid on the image including twelve squares, calculating full/empty ratios of the twelve squares of the grid and storing them in a user table, using the length of the foot and the user table in a lookup table of a database to find a size and a fit of an article of footwear that is most suitable for the foot of the user.

A method for determining best fitting footwear includes acquiring a static 3D scan of a user's feet; generating a static 3D model of the user's feet; modifying the static 3D model to generate a dynamic 3D model that corresponds to changed shape of the user's feet when performing an athletic activity; identifying a footwear that best matches the dynamic model; and informing the user of the footwear that best matches the dynamic model. Optionally, the static 3D scan is retrieved from a database, or generated on the fly, or based on images from a mobile device. Optionally, the dynamic model takes into account a type of athletic activity, a weight distribution of the user, a load on the feet of the user, and a motion mechanism and strike type. Optionally, the dynamic model modifies a foot length, a foot width at ball, and a foot width at bottom.

Components and assemblies for acquisition and analysis of data collected from sites such body surfaces, footwear and apparel, objects, accessories, and the like are directed to providing intermittent and/or continuous monitoring and reporting of conditions such as force, pressure, shear and other conditions, activity and/or environmental parameters at body locations and/or at an interface of a body location and an object. In one aspect, sensor assemblies comprise one or more sensor(s) and/or associated electronics associated with at least one non-conductive carrier layer. Electronic components including sensor acquisition systems (SAS) and dedicated electronics devices (DED) providing electronics components for signal conditioning, data collection, storage, analysis, feedback, communications and optional sensing capabilities are also described.

The invention allows foot measurement for selecting ready-made footwear that provides accurate results efficiently, easily and with low costs, and which can be performed both at home and at stores. An apparatus (120) of foot measurement comprises a base plate (121) and a single circumference measurement loop (123). The base plate (121) is utilized in measuring the length (401) of a foot, and an elastic portion (123A) of the circumference measurement loop (123) is utilized in measuring the circumference (402) around the ball of the foot.
