As an upgraded version of traditional physical sand tables, real estate digital sand tables demonstrate numerous significant advantages empowered by technology. They break through the spatial limitations of physical models. Through technologies such as 3D modeling, VR/AR, multi-dimensional interactions are realized — users can freely zoom in/out the perspective, switch between building details, and even simulate walking or driving routes, intuitively experiencing the community layout and surrounding facilities. They have a larger information capacity, being able to integrate data such as house type maps, decoration plans, real-time housing prices, and plans for surrounding schools/business districts. All such information can be retrieved with a click, avoiding the limitation of single information in traditional sand tables. They are highly flexible, with data that can be updated in real-time. For example, adjusting building colors or adding new planning content does not require remaking physical models, thus significantly reducing costs. Meanwhile, they support remote online display, allowing customers to have an immersive experience without being on-site. This is especially suitable for off-site house viewing scenarios, which not only improves marketing efficiency but also makes house purchase decisions more convenient and accurate.
