Dice Scanning Device Calibration Zone and Imager
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gaming devices face challenges in maintaining precise and reliable imaging under varying environmental conditions, such as changes in ambient lighting, shadows, and reflections, which affects the accurate detection and interpretation of game objects like dice. Additionally, traditional calibration methods require user intervention, disrupting the gameplay experience and potentially obstructing the imager's view.
Innovation Solution
A gaming device with an imager configured to detect objects within a playing area and calibration signals in a calibration zone outside the playing area. The device includes a calibration element providing a substantially transparent region for environmental light and one or more calibration markers. This setup allows for automatic calibration without user interaction, ensuring accurate object detection under various lighting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional calibration methods are used requiring user intervention, then calibration can be performed, but the gameplay experience is disrupted and the imager's view may be obstructed
Solution Approach 1:
The calibration element is pre-positioned on the imager before gameplay begins. The calibration markers are automatically detected by the imager at the start of a gaming session, enabling calibration to occur in advance without requiring user intervention during actual gameplay. This preliminary calibration action ensures the imager is properly calibrated while maintaining gameplay immersion.
Solution Approach 2:
The system performs self-calibration by automatically detecting calibration markers positioned on the imager. The calibration process occurs autonomously without requiring manual user intervention, thereby maintaining gameplay immersion while ensuring reliable calibration accuracy. The imager itself initiates and completes the calibration sequence.
2Reliability
If calibration markers are placed within the playing area, then calibration can be performed, but the movement of game pieces is interfered with and the imager's view is obstructed
Solution Approach 1:
The calibration function is segmented from the playing area by positioning calibration markers in a dedicated calibration zone adjacent to but separate from the playing surface. This spatial segmentation allows calibration markers to be detected without interfering with game piece movement or obstructing the imager's view of the playing area during gameplay.
Solution Approach 2:
A calibration zone serving as an intermediary area is established between the imager and the playing area. Calibration markers are placed in this intermediate zone, allowing the imager to access calibration signals without the markers becoming part of the playing field and potentially obstructing views or interfering with game pieces.
3Adaptability or versatility
If the imager is exposed to varying environmental conditions, then the device can operate in different settings, but detection precision deteriorates due to lighting changes, shadows, and reflections
Solution Approach 1:
The system performs preliminary calibration in the actual environmental conditions where it will operate, before gameplay begins. By detecting calibration markers and adjusting imaging parameters in advance, the system adapts to the specific lighting conditions, shadows, and reflections present in the environment, ensuring high detection precision when gameplay occurs.
Solution Approach 2:
The calibration process incorporates feedback from the environmental conditions by having the imager detect calibration markers and automatically adjust imaging parameters based on the detected lighting conditions. This feedback mechanism enables the system to adapt to varying environmental conditions while maintaining precise object detection accuracy throughout the gaming session.

AI summary
A gaming device comprises an imager configured for detecting objects within a playing area, such as for example dice or cards. The imager is also configured for detecting calibration signals in a calibration zone outside the playing area. The gaming also comprises a calibration element configured for providing a substantially transparent region for environmental light to reach the imager in the calibration zone and for further providing one or more calibration markers in the calibration zone. The gaming device thereby is configured for performing calibration using the one or more calibration markers of the calibration element.
