New Publication at COSIT 2024: Exploring Perceived Feasibility and Use Cases of 3D Sketch Mapping

Can you sketch in 3D?

Within the 3D Sketch Maps project, our former colleague, Prof. Kevin Gonyop Kim, and the geoGAZElab team investigated the perceived feasibility of 3D sketching in VR with a particular focus on the sketch mapping purpose. We interviewed 27 people from 3 domains and discovered that 3D sketching can help represent 3D information more effectively and complement the 2D approach. The paper was presented at the COSIT 2024 conference in September in Quebec City, Canada, by Prof. Martin Raubal and received attention and various questions.

New publication in the International Journal of Human-Computer Studies

The 3D Sketch Maps project team recently published a paper entitled:  VResin: Externalizing spatial memory into 3D sketch map. In this paper, we refined the concept of 3D sketch maps, proposed a technological framework using 3D Cartesian coordinate axes, and provided design criteria for 3D sketch mapping interfaces. We implemented a VR-based 3D sketch mapping tool called VResin, which is associated with traditional resin painting, and a layer-by-layer sketching interface that considers both researcher and user needs. We then conducted a comparative user study with 48 participants between mid-air sketching and layer-by-layer sketching interfaces for memorising multi-layered buildings. We found that VResin helps users to create less distorted sketches while maintaining the level of completeness and generalisation compared to mid-air sketching in VR. Finally, we presented application scenarios demonstrating how 3D sketch maps can support people’s externalisation of their 3D spatial understanding. This study is part of a Sinergia project called “3D Sketch Maps”, funded by the Swiss National Science Foundation (SNSF) [grant number 202284].
