Measurements that are Fast on their Feet
The simple task of measuring feet has taken a step forward into the optical future, thanks to a technology called FootSee developed by QinetiQ. The optical technique uses an infra-red LED light source to project an array of dots onto both feet simultaneously. The distorted array is recorded by 6 cameras and a software algorithm produces a 3D representation of the feet. Compared to manual techniques, this method provides more detailed information on foot shape and size (±1 mm) and in a fraction of the time. The information can be stored in a database, allowing stores to improve their service and enabling shoe companies to improve their products and track trends in the market place.
FootSee has already been in use across the UK in Clarks shoe stores and is now being trialled in the USA in Stride Rite stores. Currently, the emphasis is on fitting shoes for children; quite apart from their lack of cooperation when it comes to being fitted for shoes, it is also more critical that shoes for developing feet are properly designed for them.
The commercial success of this technology, which was originally developed for military applications, is unlikely to stop here. Detailed measurements of the body for sports equipment or safety gear, are just some of the areas in which this technology might see further development.
