Item Low-budget 3D Printed Haptic Navigation Aids for the Visually Impaired(The Eurographics Association, 2016) Michalik, Neena; Fryazinov, Oleg; A. Medeiros e Sa and N. Pietroni and K. Rodriguez EchavarriaIn a culture shaped by the visual, having a visual impairment can present many difficulties, in particular concerning orienta- tion and spatial awareness. Tactile models that allow users to experience an environment haptically can provide the spatial, object-based and sequential information necessary to facilitate visually impaired individuals' orientation and mobility in the environment. The increasing availability of 3D printing technologies and digital model data would allow for the creation of customisable tactile models tailored to an individual's needs and without high costs for design and fabrication. In this paper we explore design and fabrication of low-budget 3D printed tactile models for testing on real users.Item Restoration of Architectural Ornament for Historic Buildings(The Eurographics Association, 2016) Echavarria, Karina Rodriguez; Song, Ran; Few, Dean; Sá, Asla Medeiros e; A. Medeiros e Sa and N. Pietroni and K. Rodriguez EchavarriaMany geographic areas within cities and towns across the world display historic buildings with stylised architectural elements displaying the influences of periods and cultures throughout their history. Ornamental mouldings are architectural elements which are commonly found both in façades and the indoors of historic buildings. These mouldings support the embellishment of a building; however, its proper maintenance can be expensive. This is because, until now, the restoration and conservation of ornamental mouldings has been mainly a manual artisan activity. This research explores the introduction of digital fabrication technologies into this process. Digital Fabrication technologies, including graphic algorithms and additive manufacturing technologies, enable the design and fabrication of customisable ornamental mouldings. Hence, this paper proposes the definition and testing of a graphical workflow for the fabrication of ornamental mouldings. The restoration and conservation of historic buildings is a major economic sector in Europe. Hence, this paper contributes towards lowering their maintenance cost and making more accessible the ornamentation of new buildings.
