### Video Recognition

#### Costs
- Developing and implementing a video recognition system can incur significant expenses, including hardware, software development, and ongoing maintenance costs.

#### Limited Applicability
- Video recognition may not be suitable for all types of games, although for a specific card deck, this limitation may not be significant.

#### Technical Challenges
- Implementing video recognition and voice output can be technically demanding and may require advanced hardware and software.
- Card recognition and real-time processing pose significant challenges.

#### Technical Problems
- Card Recognition Accuracy: Identifying cards accurately from a video feed can be challenging due to various factors such as lighting conditions and card orientation.
- Real-Time Processing: Achieving real-time processing for effective gaming experience can be technically demanding.
- Hardware Requirements: Real-time video recognition may necessitate powerful hardware components.
- Environmental Factors: Changes in lighting conditions and other environmental factors can affect the accuracy of video recognition.
- User Interface and Interaction: Developing an intuitive user interface for blind individuals presents challenges.

#### Comparison to NFC/RFID System
- Video recognition requires less equipment and no physical modifications.
- NFC/RFID systems offer faster, more reliable, and consistent performance.
- NFC/RFID systems avoid some difficulties associated with video recognition, such as environmental factors.
- Video recognition can be adapted to a broader range of games without altering physical components.

#### Comparison to Snapshot VR
- Video recognition provides real-time feedback and continuous monitoring.
- Snapshot VR offers reduced processing load and simpler debugging.
- Snapshot VR may experience delays in providing information and may miss game changes between snapshots.

#### System Overview
1. **Camera**: A camera captures the game.
2. **Computer**: Connected to the camera, processes the video feed.
3. **Software**: Special software recognizes the cards and communicates with users.
4. **Website**: Displays game information for blind users.
5. **Voice or Sound**: Provides auditory feedback to players.
6. **Internet**: Facilitates gameplay with distant friends.
