Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems with touch panels are limited in the types of operations they can receive, as they rely on a single operation device for input detection.
Innovation Solution
An operation input device that includes a processor and memory, capable of detecting touch points on a touch panel and determining operations based on the distance and positional relationship of multiple touch points, allowing for more complex and varied operations to be recognized.

Engineering Contradiction Analysis
1Adaptability or versatility
If a single operation device is used for input detection, then the device complexity is reduced, but the types of operations that can be received are limited
Solution Approach 1:
The touch panel serves multiple functions: it detects both traditional touch operations and operations from multiple operation devices arranged on its surface. The system determines operation types based on the spatial relationships and distances between touch points, allowing a single device to handle diverse input modes without requiring separate dedicated sensors for each operation type.
Solution Approach 2:
The invention transitions from detecting single-point touch operations to analyzing multi-point spatial relationships on the touch panel. By evaluating the distances and positional relationships between multiple touch points, the system can identify operations from multiple operation devices, effectively adding a spatial dimension to operation detection.
2Adaptability or versatility
If multiple operation devices are arranged on the touch panel, then the types of operations increase, but the difficulty of detecting and measuring operations increases
Solution Approach 1:
The system replaces complex mechanical or dedicated sensing mechanisms with computational geometry algorithms. By calculating distances and positional relationships between touch points detected by the touch panel, the system determines operation types through mathematical analysis rather than requiring separate detection mechanisms for each operation mode.
Solution Approach 2:
The invention changes the detection parameters from simple touch point coordinates to derived parameters including distances between points and positional relationships. These transformed parameters enable the system to distinguish between different operation types (single device operations, multiple device operations, and pure touch operations) based on geometric characteristics.

AI summary
The operation input device determines an operation of one or a plurality of operation devices on the basis of the distance between touch points and the positional relationship of three or more touch points, and determines an operation corresponding to the touch point determined not to depend on the operation device as a touch operation.
