In the world of textures applied to products, three-dimensional textures stand out for their notable interaction with users, who perceive them through vision and touch. Furthermore, textures are part of everyday life, as they are found on the surfaces of most objects. When designing three-dimensional textures for products, elements are brought together that help not only from an aesthetic point of view, but also in the practical function of the object (GOMES FILHO, 2010). In this way, three-dimensional textures can be used to add functionalities to products, such as: providing increased safety in use; increase performance and reduce the use of force in manual activities; avoid the risk of vandalism on surfaces; confer structural resistance to materials; favor thermal comfort and facilitate the dissipation of heat, light and sound. Although three-dimensional textures are applied to different materials (FIORANI, PASSARO and CURTO, 2010), we chose to analyze them when produced in polymeric materials, since their occurrence in these materials is intense. This statement is because most industrial processes for obtaining plastic products (such as injected blowing, extruded blowing and thermoforming) can have their tools easily textured. Admitting that the development of three-dimensional textures forms the field of activity of project practice in product design, it becomes important to research the character of three-dimensional textures existing on the surface of objects, seeking to generate knowledge regarding objective and subjective aspects related to functionality and their implications in the field, gathering more detailed information, such as: their constitutive characteristics, classes of products in which they appear, types of polymers in which they affect, in addition to the sensations and tactile perceptions provoked. The tools used for data collection were divided into two parts, these being: 1st (objective aspects) - physical or digital measurement to survey the constituent characteristics of three-dimensional textures and survey of materials through information provided by suppliers or through laboratory tests (when in possession of the objects); 2nd (subjective aspects) - netnographic research (via the YouTube platform) and semi-structured interviews with presentation of physical samples; At the end, a content analysis will be carried out seeking to present design guidelines for new developments, in addition to beginning the creation of a taxonomy (initially restricted to objects that have manual tactile interaction with palm grip) of texture modalities based on three parameters : module, polymer class and product categories. This study is based on theories of surface design practices, product design, ergonomics, and sensory perception.
