    This research contributes towards the need to decolonise material culture knowledge by reaching out to communities across the world who still practice the intangible heritage of craft and linking their knowledge with the historical collections curated and exhibited in western heritage institutions. Craft know-how has been transmitted from past generations and in many instances still plays a key role in the economic development and social welfare within communities. Such development includes creative and handicraft industries which are under threat by mass production and the loss of traditional know-how. For western museums, the documentation of knowledge around craft can enhance our understanding and interpretation of collections. For communities, there is a potential to support preserving their endangered knowledge while offering opportunities to seek innovation through the digital transformation of their practices to benefit at a financial and socioeconomic level. This paper describes an ongoing research project which deploys visual methods and linked data to document and provide access to the intangible knowledge of the craft, which is practised by Egyptian woodwork crafters in the historic centre of Cairo.

    Tactile prints in colour: Studying the Visual Appearance of 2.5D Prints for Heritage Recreations
    (The Eurographics Association, 2022) Trujillo-Vazquez, Abigail; Rodriguez Echavarria, Karina; Weyrich, Tim; Ponchio, Federico; Pintus, Ruggero
    Printing applications for heritage recreation are a means to allow audiences to appreciate details and engage with cultural materials through closer interaction. A 2.5D print is a media suitable to incorporate visual and tactile qualities such as colour, low relief, textures and roughness. Designing a colour-accurate tactile print requires, nevertheless, anticipating how specific shapes and meso-geometries will affect the reflective properties of the surface, thus changing its appearance. Hence, this paper contributes to improve the understanding of the interaction between geometry and colour when deploying 2.5D prints so that tactile portable replicas can be easily produced. For this, we have produced a series of 2.5D printed patches with varying meso-textures, based on procedural noise functions, and measured their colour coordinates and glossiness. We aim to find a correlation between colour shift (expressed as lightness, chroma and ?E) and the scale and distribution of surface details.
