In the case of the mechanical operations (e.g. interior tooling, patterning, trimming, assembling operations) or assembling tasks (e.g. putting together last and insole), metrology software allows production robots to measure keyhole geometry, hatch emboss moulds, build toolpaths, check and certify optical reference points, assist operation training... In all the work presented in this chapter there are a high number of operations that cannot be carried out with robots, as they require manual intervention to perform, and they all have a tangible motive: to reduce mistakes and increase safety and robustness. To automate these tasks, we exploited services provided by the VirMat project [17], an open source project aimed at the open source exchange in process and product design challenges between the Virtual Reality (VR) and the real world, in which we are also involved. In this case, visual perception techniques and locomotion techniques have been integrated for the real-time perception of virtual tools, and for the real-time interaction with a virtual real 3D environment, such as in the case of kinematic computer-aided design (CAD) tools, highly interactive surfaces, virtual 3D modelling and virtual 3D patterning. Furthermore, in order to facilitate the training of operators for specific jobs, we exploited the service Virtual Reality (VR). The VR system can provide visual, auditory and tactile feedbacks [18] in a realistic way with almost any type of video display [19], specially equipped with 3D perception and videogames [20]. The VR environment is controlled by a precise marker-based motion capture system, which captures and tracks the positions of any body marker fixed on the operators’ avatar using depth sensors and provides the position of a virtual correspondences point at the real scene [21, 22]. Each marker of the motion capture system can be associated to any object of the workspace, by identifying a fiducial marker specific for each virtual element or tool. For specific tasks such as sewing, the operator placed the embroidery machine-arm on top of each 2D pattern and sequentially operated virtual buttons to perform specific tasks (see Fig. 2). This type of interaction has been mainly used to teach and train operators in a period of time suitable to the manufacturing process of the footwear. d2c66b5586
