1Loss of information

If existing specialized devices capture basic geometric information of real-world objects, then the device complexity is reduced and processing is simplified, but the material property representation is insufficient leading to sub-optimal interaction between simulated and real objects

Engineering Contradiction:
Improvematerial property informationVSAvoidimage processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system changes the parameters of image analysis from basic geometric extraction to include material property identification. By analyzing multiple image sequences and applying machine learning algorithms, the system extracts material categories and properties (such as texture, reflectivity, transparency) in addition to geometric information, thereby reducing information loss while managing processing complexity through intelligent algorithms

Inventive Principle:

Solution Approach 2:

The system creates virtual copies of real-world objects that inherit and emulate the material properties of the captured objects. These virtual objects are generated by copying not only geometric data but also material characteristics from the analyzed image sequences, enabling realistic interactions between virtual and physical objects in the mixed reality environment
