Surface Computer Object Image Rendering via Localized Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-touch surface computing systems lack the ability to efficiently detect and display images of objects placed on their surface without interfering with existing graphical user interface (GUI) elements or modifying other rendered images.
Innovation Solution
A surface computer system that uses a scanner to detect objects on its surface, identify the region, and create an object image using infrared technology or other scanning methods, rendering the image within the identified region without altering other GUI elements outside that area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If the surface computer scans the entire surface to detect objects, then object detection capability is improved, but the time required for scanning and processing increases
Solution Approach 1:
The surface computer divides the scanning surface into multiple regions and scans only the region where an object is detected, rather than scanning the entire surface. This segmentation approach reduces the total scanning area and processing time while maintaining effective object detection capability.
Solution Approach 2:
The system performs partial scanning by focusing only on the necessary region (where the object is located) rather than scanning the entire surface. This partial action approach reduces time consumption while achieving the detection objective.
2Illumination intensity
If the surface computer renders object images across the entire surface, then visibility and user interaction are improved, but existing GUI elements are obscured or modified
Solution Approach 1:
The surface computer renders the object image only within the specific region where the object is located, rather than across the entire surface. This local rendering approach ensures that the object is visible and interactable while leaving other regions (including existing GUI elements) unchanged and unobscured.
Solution Approach 2:
The display surface is segmented into the object region and other regions. The object image is rendered only in the object region, while other regions maintain their original content including GUI elements. This segmentation resolves the conflict between object visibility and GUI element preservation.
3Measurement precision
If the surface computer uses comprehensive scanning methods to ensure accurate object detection, then detection precision is improved, but the complexity of the scanning system increases
Solution Approach 1:
The scanning system is segmented to scan only the necessary region rather than the entire surface. This reduces the complexity of the scanning system by limiting the scan area while maintaining detection precision through focused scanning of the object-containing region.
