Game Device Card Detection with Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In card game devices, users face challenges in completing intended movement operations due to the need to repeatedly shift gaze between the board surface and a display device, leading to potential unintended operation inputs, especially under time constraints or for inexperienced users.
Innovation Solution
A game device with a first display area for placing user items and a computing device that recognizes item information, including game characters, using invisible codes printed on cards, allowing for real-time detection and display of card positions and orientations, thereby ensuring user awareness of recognized items without requiring gaze shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user focuses only on the board surface to perform movement operation, then the movement operation can be performed, but unintended operation input might be recognized by the game device
Solution Approach 1:
The display device provides visual feedback showing the current detection position and status of the item on the board surface. This feedback mechanism allows users to confirm their movements are being correctly detected while maintaining focus on the board surface, preventing unintended operations from being misinterpreted.
Solution Approach 2:
The system adds a visual dimension by displaying the item's detection position and status on the display device while the physical item remains on the board surface. This dual-display approach allows users to monitor operation status without shifting gaze from the board surface.
2Reliability
If the user shifts gaze between the board surface and the display device to confirm operation, then operation status can be verified, but the user cannot complete intended operation input under time limits
Solution Approach 1:
The display device presents operation status information in a separate visual dimension from the physical board surface. Users can simultaneously monitor the item's detection status on the display while performing movements on the board surface, eliminating the need to shift gaze and reducing operation time.
Solution Approach 2:
Real-time visual feedback on the display device shows the current detection position and operation status continuously. This allows users to verify operations are being correctly detected without interrupting their focus or timing, as the feedback is available simultaneously with the movement operation.
3Adaptability or versatility
If a plurality of cards overlap on the board surface, then multiple items can be placed, but the card is moved outside of the detection range of the board surface
Solution Approach 1:
The display device provides visual feedback showing the detection status and position of each item, even when multiple items are overlapping on the board surface. This feedback mechanism helps users understand which items are detected and their positions, maintaining measurement precision despite overlapping placements.

AI summary
A game device for playing a game includes a first display having a first display area, and being configured to display images for the game in the first display area, the first display area including an operation area on which a user item of a user is movably placeable, a computing device, and a storage medium containing program instructions stored therein, execution of which by the computing device causes the game device to provide the functions of: obtaining item information from the user item, the item information including a game character that is used by the user in the game, executing the game using the item information, and controlling displaying of the first display, by causing an associated image that is associated with the user item that has been movably placed on the operation area to display in the first display area.
