“…Other works try to use 3D sketch as primary interaction to retrieve models comparing traits and colors to shapes and textures. Li et al 's [35] work compares multiple 3D sketch-based algorithms for 3D model retrieval. They gather hand-drawn 3D sketches and generate a dataset paired with a 3D model collection.…”

“…Despite the growing interest in methods for Sketch-based Retrieval [9,10,21,29,30], only few examples apply to VR [20,25]. The reason for this is twofold: (1) the ability for sketch descriptions of an object to adequately express the model, and (2) ability for users to get confidence with the depiction of structural elements.…”

Drawing tools for Virtual Reality (VR) enable users to model 3D designs from within the virtual environment itself. These tools employ sketching and sculpting techniques known from desktopbased interfaces and apply them to hand-based controller interaction. While these techniques allow for mid-air sketching of basic shapes, it remains difficult for users to create detailed and comprehensive 3D models. In our work, we focus on supporting the user in designing the virtual environment around them by enhancing sketch-based interfaces with a supporting system for interactive model retrieval. Through sketching, an immersed user can query a database containing detailed 3D models and replace them into the virtual environment. To understand supportive sketching within a virtual environment, we compare different methods of sketch interaction, i.e., 3D mid-air sketching, 2D sketching on a virtual tablet, 2D sketching on a fixed virtual whiteboard, and 2D sketching on a real tablet. Our results show that 3D mid-air sketching is considered to be a more intuitive method to search a collection of models while the addition of physical devices creates confusion due to the complications of their inclusion within a virtual environment. While we pose our work as a retrieval problem for 3D models of chairs, our results can be extrapolated to other sketching tasks for virtual environments.
