This becomes a critical factor in the design of soft products. However, customized design of soft products remains a challenging task, mainly because of ineffective communication with end customers and higher manufacturing costs compared to mass production items. To overcome these deficiencies, this work aims at developing new customized design technologies based on the augmented reality concept. Two major functions are proposed for design of children footwear: product appearance adjustment and assembly between virtual and real objects. Our focus is to facilitate high fidelity and interaction in virtual product evaluation with recent advances of ICT. First, children footwear is decomposed into several modules. A large amount of product variants are thus generated by varying the design attributes of those modules. A new module, show cloth, is proposed to quickly change the footwear appearance. Tabu Search is applied to optimize the developability of the cloth surface, ensuring its higher manufacturability. The second function is to accomplish the assembly process between real and virtual objects using the video stream as user interface. The assembly information is extracted from the depth and image data captured by real-time sensing technologies through image processing and data regression. The result enables precise assemble of a virtual model with respect to real objects. High Dynamic Range Image techniques provide a higher visualization quality in the assembled product and enhance the quality in virtual product evaluation. This research provides customized design tools from the product user perspective. We also demonstrate the advantages of real-time sensing technologies in product design and interactions. Those tools facilitate better communication between designers and users. The concept of co-creation with users is thus realized.
