Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional online shopping platforms provide limited visual experiences and complex user interactions, leading to increased risks of buying defective products and inefficient shopping processes, with existing 3D imaging technologies being costly and unsuitable for personal online shopping.
Innovation Solution
A three-dimensional shopping platform displaying system for mobile terminals, comprising a three-dimensional model, display unit, motion capture unit, and perspective switch unit, allowing users to interact with virtual stores and merchandise through intuitive gestures and angular velocity sensors, enabling zooming, rotating, and navigating within a graphic displaying area on the mobile screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional two-dimensional display method is used, then the system complexity is low, but the visual experience and understanding of merchandise appearance is limited
Solution Approach 1:
The patent transitions from traditional two-dimensional display to three-dimensional virtual store display, enabling users to view merchandise from multiple angles and perspectives. This dimensional change provides comprehensive visual information about product appearance while maintaining system feasibility through software-based 3D rendering on mobile terminals.
Solution Approach 2:
The patent creates virtual copies of physical stores and merchandise in a three-dimensional digital environment. These virtual models replicate the appearance and spatial arrangement of real stores, allowing users to explore and view products without physically visiting the location, thus providing complete visual information through digital reproduction.
2Ease of operation
If traditional keyboard and mouse operation is used, then the device complexity is low, but the user interaction efficiency and experience is poor
Solution Approach 1:
The patent replaces traditional mechanical input devices (keyboard and mouse) with touch screen gestures and motion capture technology. Users can interact with the three-dimensional virtual store through intuitive touch operations and device movements, significantly improving ease of operation and reducing the time required to navigate and select products.
3Loss of information
If existing 3D imaging technology is applied, then the visual experience is improved, but the implementation cost is high and not suitable for personal online shopping
Solution Approach 1:
The patent utilizes the mobile terminal's existing camera and processing capabilities to capture and render three-dimensional images, rather than requiring specialized expensive 3D imaging equipment. The mobile device itself serves multiple functions: capturing images, processing data, displaying the virtual store, and handling user interactions, making the technology accessible and cost-effective for personal online shopping.
Data Source
AI summary
A three-dimensional model, a display module, a motion capture module and a perspective switch module is provided. The perspective switch module is respectively connected to the display module and the motion capture module. A preset-sized graphic displaying area is defined in the display module. The motion capture module changes the relative position between the graphic displaying area and the three-dimensional model according to the manipulation of the user. The perspective switch module adjusts the three-dimensional model according to the control instruction transmitted by the motion capture module. Simultaneously, the different graphic data are displayed within the graphic displaying area. The graphic data are the projections of the three-dimensional model in the plane of graphic displaying area.
