Working machines in construction sites or emergency scenarios can operate in situations that can be dangerous to an operator such as direct control of the machine or teleoperation in co-presence. Remote operation has been typically hindered by limited sense of presence of the operator in the remote of the environment to due the reduced field of view of cameras. Starting from these consideration we are introducing a novel real-time panoramic telepresence system for construction machines. This system does allow fully immersive operations in critical scenarios while keeping the operator in a safe location at moderate distance from the construction site. An omnidirectional stereo vision head, mounted over the machine, acquires and streams data to the operator with a streaming technique that focuses on the current direction of site of the operator. According to the motion of the operator’s head, the telepresence system will determine the involved cameras to use and the appropriate region of interest in cameras. The operator uses a head-mounted display to experience the remote site also with the possibility to view digital information overlaid to the remote scene as a type of augmented reality. The paper addresses the design and architecture of the system starting from the vision system and then proceeding to the immersive visualization.

The mounting issue of environmental care requires to apply better disassembly operations at the product’s End of Life. Planning and reckoning different disas-sembly strategies in the early stage design can improve the sustainable products conception. Nowadays many computer aided process planning software provide the optimized assembly or disassembly sequences, but they are mainly based on a time compression and cost compression approach. In this paper a novel method concerning design for disassembly is described and validated. An Augmented Reality environment has been implemented and modified integrating real human movements and virtual part unmounting in a mixed session. In such way, the op-erator may in a more natural and intuitive way test not only automatic disassem-bly sequences, but also different original strategies. The use of haptic devices guarantees more interaction with the 3D model than ordinary devices (mouse and keyboard). The method has been tested and compared with automatic optimiza-tion methods in order to demonstrate the improvements in disassembly strategy
221. VR-based Product Personalisation Process for Smart Products

Through the synergies of advanced IT technologies in sensor network and hardware infrastructure, both industrial and consumer products are evolving rapidly to carry more smart features. To sharpen competitive edge in global market, manufacturers today ought to enable their customers to personalize their products to meet diversifying customer needs (CNs). However, the increasing complexity of smart product is dramatically expanding the design space due to over-loaded smart features, which results in significant challenges in the personalization of smart products. Typically, manufacturers operating in a configure-to-order (CTO) manner would adopt a mass customization strategy and implement it with a product configuration system (also known as product configurator). The user experience (UX) of personalizing products by conducting product configuration is crucial for encouraging customer retention and loyalty. This project studied the product personalization process for smart products by observing a group of customers conducting a series of product configuration tasks in several types of product configurators we developed for different platforms (web-based and Virtual Reality (VR) based version). By analyzing mental and physical reaction of the customer, a more systematic understanding of user preference has been attained. The proposed VR-based approach for realizing customer-centric product personalization has been proved to be valid and should be a valuable reference in the future development of the product configuration system.
