Multi-Layer Touch Interface Layer Selection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen devices require users to grasp the number of fingers associated with each layer to operate display objects, making it difficult to choose the correct layer for operation targets when objects are superposed or closely displayed.
Innovation Solution
An operating device with a display, detector, and determiner that displays multiple image layers on a screen, allowing the detector to determine which display region is chosen based on user input, eliminating the need to select a specific layer by finger count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple display objects are superposed or closely displayed on a screen, then the information density is improved, but the ease of operation deteriorates because users must grasp the number of fingers to choose the correct layer
Solution Approach 1:
The patent applies the dimensionality change principle by introducing a new dimension for layer selection - visual display indicators showing which layer is currently selected. Instead of relying solely on the familiar dimension of finger count, the system adds a visual feedback dimension that guides users to the correct layer, making multi-layer operation intuitive even when many objects are superposed on the screen.
2Area of stationary object
If display objects are closely arranged to save screen space, then the area utilization is improved, but the measurement precision deteriorates because it becomes difficult to accurately identify which object is being operated
Solution Approach 1:
The patent applies color changes by using visual indicators with distinct appearances (such as highlighted borders, background color changes, or icon transformations) to mark the currently selected layer's display objects. This visual differentiation allows users to easily identify which objects belong to the active layer even when objects are closely arranged, maintaining position identification accuracy while maximizing screen space utilization.
Data Source
AI summary
An operating device includes a display, a detector and a determiner. When the detector detects a designated position, the determiner determines whether or not a position corresponding to the designated position in a first layer is within a display region by first image data. When the position is within the display region, the determiner determines that the display region by the first image data is chosen. When the position is not in the display region, the determiner determines whether or not a position corresponding to the designated position in a second layer is within a display region by second image data. When the position in the second layer is within the display region by the second image data, the determiner determines that the display region by the second image data is chosen.
