Dual LCD Touch Panel Handheld Game Map Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held game apparatuses with two screens are limited in displaying complex game maps, leading to monotonous gameplay and ocular fatigue due to fixed viewing angles, as they lack the ability to freely change or zoom in/out of game maps, which is essential for RPGs, SRPGs, and action games.
Innovation Solution
A hand-held game apparatus with two liquid crystal display sections and a touch panel that allows users to arbitrarily change the displayed state of narrow-range and broad-range maps by manipulating the touch panel, enabling seamless navigation and strategic gameplay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single TV screen is used for displaying game maps, then the device structure is simple, but the user cannot freely change or zoom in/out of game maps leading to monotonous gameplay
Solution Approach 1:
The display system is segmented into two separate liquid crystal display screens (first LCD and second LCD), allowing independent display of different map ranges. This segmentation enables simultaneous display of both narrow-range and broad-range maps, providing flexibility without requiring a single complex display system
Solution Approach 2:
The patent adds a spatial dimension to map navigation by providing two distinct display areas (upper and lower screens) where users can view different map ranges simultaneously. This dimensional approach allows users to switch between narrow-range and broad-range views without relying on a single display's zoom capabilities
2Adaptability or versatility
If two liquid crystal display sections are provided for displaying narrow-range and broad-range maps, then map exploration freedom is improved, but the device structure becomes more complex
Solution Approach 1:
Both liquid crystal display sections are controlled through a single touch panel, allowing the touch panel to serve multiple functions (controlling both displays). This multi-functionality reduces the need for separate control systems for each display, thereby limiting the increase in device complexity while maintaining map viewing flexibility
3Ease of operation
If the game screen is fixed on a TV screen, then the display system is simple, but ocular fatigue occurs due to fixed viewing angles
Solution Approach 1:
The viewing experience is segmented across two vertically arranged liquid crystal display screens, allowing users to view different map ranges at different positions. This segmentation enables more natural head positioning and reduces ocular fatigue associated with fixed single-screen viewing angles
Solution Approach 2:
The touch panel acts as an intermediary control interface that manages both liquid crystal display sections. By providing a unified control mechanism, it simplifies the interaction complexity despite having multiple display sections, making the dual-display configuration easier to operate

AI summary
A hand-held game apparatus and game program allow a user to play a game while going back and forth between a narrow-range map and a broad-range map-game. The player can manipulate a touch panel mounted on a display for displaying the broad-range map. If the player manipulates the touch panel to point to a coordinate position on the broad-range map, thus designating coordinates for a narrow-range map to display, an image of the narrow-range map, which is changed as desired, is displayed. If the player indicates a moving direction on the broad-range map to designate a scroll direction, the displayed broad-range map is moved (scrolled).
