Virtual Operation Region for Information Processing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices face challenges in setting a virtual operation region that is easy for users to operate, often resulting in small touch detection ranges and erroneous detections due to the proximity of the touch determination surface to the user.
Innovation Solution
An information processing device that includes a processor and memory, capable of receiving images, detecting arm portions, and setting a virtual operation region based on the arm's position and length, thereby defining a detection enabled region and touch determination surface to accurately detect fingertip movements and prevent erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch determination surface is set close to the user for easy operation, then the ease of operation is improved, but erroneous detections increase due to proximity
Solution Approach 1:
The patent transitions from 2D touch surface coordinates to 3D spatial coordinates by detecting arm portion positions and lengths. This dimensional change allows the system to establish a virtual operation region in three-dimensional space, enabling accurate fingertip position detection while maintaining a user-friendly touch surface configuration.
Solution Approach 2:
The patent introduces arm portion detection as an intermediary between the user and the touch determination surface. By detecting the arm portion position and length, the system creates a virtual operation region that mediates between the physical touch surface and the user's hand, preventing erroneous detections while preserving ease of operation.
2Ease of operation
If the virtual operation region is expanded for easier operation, then the ease of operation is improved, but the measurement precision of fingertip position decreases
Solution Approach 1:
The patent implements dynamic adjustment of the virtual operation region based on real-time detection of arm portion position and length. The virtual operation region is not fixed but adapts to the user's actual arm configuration, maintaining measurement precision while accommodating variations in user reach and operation comfort.
Solution Approach 2:
The patent changes the parameters defining the virtual operation region based on detected arm portion characteristics. By adjusting the virtual operation region's position, size, and shape according to measured arm length and position, the system optimizes both the ease of operation and the precision of fingertip position detection within that region.
