The Impact

In the last two decades, urban planners have embraced digital technologies to complement traditional public participation processes; research on the impact of smarter digital instruments, such as immersive virtual reality (IVR), however, is scant. We recruited 40 focus group participants to explore various formats of spatial planning scenario simulations in Glassboro, NJ, USA. Our study finds that the level of participation, memory recalls of scenarios, and emotional responses to design proposals are higher with multi-sensory and multi-dimensional IVR simulations than with standard presentations such as 2D videos of 3D model simulations, coupled with verbal presentations. We also discuss the limitations of IVR technology to assist urban planning practitioners in evaluating its potential in their own participatory planning efforts.

This paper presents a novel system that allows product designers to design, experience, and modify new shapes of objects, starting from existing ones. The system allows designers to acquire and reconstruct the 3D model of a real object and to visualize and physically interact with this model. In addition, the system allows designer to modify the shape through physical manipulation of the 3D model and to eventually print it using a 3D printing technology. The system is developed by integrating state-of-the-art technologies in the sectors of reverse engineering, virtual reality, and haptic technology. The 3D model of an object is reconstructed by scanning its shape by means of a 3D scanning device. Then, the 3D model is imported into the virtual reality environment, which is used to render the 3D model of the object through an immersive head mounted display (HMD). The user can physically interact with the 3D model by using the desktop haptic strip for shape design (DHSSD), a 6 degrees of freedom servo-actuated developable metallic strip, which reproduces cross-sectional curves of 3D virtual objects. The DHSSD device is controlled by means of hand gestures recognized by a leap motion sensor.

<p><strong>Abstract.</strong> This article shows a first step in the development of an immersive virtual tour of the Cathedral of Palermo, entering the fields of Digital Cultural Heritage and Edutainment. Its purpose is to help people to gain knowledge about the site, highlighting the complex stratifications that have characterized its history.</p><p>The development of the project has been possible thanks to different phases of work: surveys were initially carried out by laser scanning, then assembled and processed to obtain the 3D model of the current state; at the same time, the model of reconstruction was processed in several phases, based on historical, archival and iconographic sources; both models were, later, subject to post-processing, preparatory to the development of virtual navigation. The tour scenario includes options in order to make it attractive for the player, such as interactive elements, interfaces and animations.</p>
