While we developed SkyLens, our team addressed several technical challenges inherent in creating advanced AR/VR applications - including real-time data synchronization, maintaining 3D spatial accuracy, and ensuring interaction responsiveness. By developing custom-built data pipelines, dynamic depth-scaling algorithms, and optimized machine learning models, we not only solved our internal technical hurdles but also created a potential blueprint for other developers facing similar obstacles.
SkyLens demonstrates the potential of AR/VR technology in transforming complex data visualization, serving as both a practical tool and a case study for academic research in data science, computer graphics, and human-computer interaction.
Pushing the Boundaries of AR/VR
Data is complicated. Visualization can help, but traditional methods fall short. Large-scale enterprises often have vast repositories of data, typically surfaced as spreadsheets or, at best, dashboards with graphs and trendlines. However, these formats require analysts to mentally transform numbers and charts into actionable insights, a process that can be time-consuming and prone to misinterpretation.
SkyLens pushes the boundaries of data visualization by contextualizing information in three-dimensional spaces. By overlaying dynamic data from various external sources in a 3D environment, users can effortlessly explore spatially contextual information. Instead of presenting data in cells or charts, SkyLens places the data next to relevant real-world objects, making it tangible and immediate.
The Meta Quest 3 headset allows a user to experience stereoscopic 3D in VR and AR, providing a rich, immersive visual experience. By utilizing the headset’s network location, we determine the GPS location of the user and retrieve data relevant to that location, including:
• Topography
• Satellite imagery
• Highway and bridge geometry
• Building geometry and texture data
• Weather conditions
• Aircraft (in-flight and on the ground), and
• Satellites visible from that location
This approach offers a more intuitive and immersive alternative to traditional web browsers for accessing and interpreting location-based information. Gathering and visualizing this spatially contextual information through conventional means would be time-consuming, awkward, and primitive in comparison.
