Image Projecting System With Dynamic Routes Around User Shadows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image projection technologies are limited by fixed, unchangeable routes that cannot be adjusted, leading to issues such as marks being obscured by user shadows or the inability to extend projection areas.
Innovation Solution
An information processing device that acquires area, route, and mark conditions to generate and output images with variable routes and marks, avoiding user shadows by using a processor and memory to control the projection of marks along customizable paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed route is projected from the image projecting device, then the projection is simple and reliable, but the route cannot be changed or adapted to different scenarios
Solution Approach 1:
The patent implements dynamic route generation by allowing the route to be changed based on different projection areas and conditions. The image projecting device can now project routes that are not fixed but can be dynamically adjusted according to the user's needs, such as extending routes to adjacent areas or changing route directions, thereby achieving adaptability without requiring a completely new system design
Solution Approach 2:
The projection area is divided into multiple manageable regions (first projection area, second projection area, adjacent areas). The route can be segmented into different paths within these regions, allowing flexible combination of route segments to create various possible routes while maintaining system manageability and avoiding excessive complexity
2Area of stationary object
If the projection area is extended to adjacent areas, then the projection area increases, but marks may be obscured by user shadows
Solution Approach 1:
The system preliminarily determines the user's movement path and predicts where shadows will fall before projecting marks. By anticipating the shadow obstruction problem, the system adjusts the route to go around shadowed areas or selects alternative mark positions that will not be obscured, thereby preventing the harmful effect before it occurs
Solution Approach 2:
The system incorporates feedback about user position and movement to dynamically adjust the projected route and marks. By continuously monitoring user movement and comparing it with the projected route, the system can detect when marks would be obscured by shadows and automatically modify the route or mark positions to maintain visibility
3Length of moving object
If the route extends in a straight direction toward the device, then the projection is straightforward, but the route cannot be extended to adjacent areas
Solution Approach 1:
The patent introduces spatial dimensionality by allowing routes to extend not only in the traditional forward direction toward the device but also laterally to adjacent areas. The route can transition from a one-dimensional straight path to a two-dimensional path that explores multiple spatial directions, enabling extension to adjacent projection areas while maintaining simplicity through systematic route generation
