In today's fast-paced world, keeping up with the latest news and information is crucial. Notice boards have been an essential tool for communication in various settings, from schools and workplaces to public spaces. However, traditional notice boards have limitations in terms of displaying dynamic content and providing interactive experiences. To address this, we propose a modern notice board that combines player and interactive modes. The player mode features updates, events, notices, and placement information, as well as daily quotes and specials. The interactive mode of the modern notice board ncludes all the features of the player mode, such as displaying updates, events, notices, and placements information. In addition, the use of button-based and gesture-based interactions enhances the user experience, making it more engaging and intuitive.

The system hardware used in the project includes a Raspberry Pi, which is a credit-card-sized computer that runs on the Broadcom BCM2837B0, Cortex-A53 (ARMv8) 64-bit SoC. The Raspberry Pi is connected to the internet using IEEE 802.11.b/g/n/ac wireless LAN. The system is designed to display information on an LCD monitor, which is connected to the Raspberry Pi through HDMI port.
For monitors with VGA ports, a HDMI to VGA converter cable is required to connect to the Raspberry Pi. In addition to displaying information, the system also allows for user interaction through the use of a webcam and 4×4 keypad. The webcam is used for gesture-based interaction, while the keypad is used for button-based interaction. Overall, the system hardware is designed to provide a seamless and user-friendly experience for both displaying and interacting with information.
Software Design and Implementation
For the software part of the modern notice board project, Python was chosen as the programming language due to its versatility and ease of use. The software is divided into three main programs: Main GUI, Updater, and Gesture Getter.
The Main GUI is responsible for displaying the content on the notice board. It was developed using PyQt5, a Python wrapper for the Qt GUI framework. The GUI provides an intuitive interface for users to interact with the notice board in both player and interactive modes. PyQt5 features like QTimer and QPainter classes are used to make GUI components much apparent.

The Updater is a sub-process of the GUI program and is responsible for retrieving data from various RSS feeds and updating the content of the notice board accordingly. Feedparser, a Python library, was used to parse and extract the data from the RSS feeds. Threading was implemented to speed up the updating process and ensure that the GUI remains responsive during data retrieval.
The Gesture Getter is another sub-process of the GUI program and is responsible for capturing gestures made by the user in front of the notice board. OpenCV and cvzone, two popular Python libraries for computer vision and image processing, were used to detect and recognize hand gestures made by the user. The gesture
recognition system allows for easy and intuitive navigation of the interactive mode of the noticeboard.
Finally, the python-vlc module was used to incorporate media content, such as videos and music, into the notice board. The module provides an easy-to- use interface for playing media files.
By combining these various software components, the modern notice board project was able to achieve its goal of providing dynamic and interactive content to users in an intuitive and efficient manner.
Interactive Mode of Operation
The user interface of the interactive notice board is intuitive and user-friendly, making it accessible to all users, regardless of their technical proficiency. When the board enters into interactive mode, the user is presented with a menu of six options to choose from: map, updates, events, notices, placements and about pages. These options are displayed in a clear and concise manner, making it easy for the user to understand what information is available and how to access it.
The menu page in the interactive mode of the notice board is a user-friendly and intuitive interface that allows users to easily navigate and access the information they need. The menu page presents users with a list of options, such as map, updates, events, notices, placements, and about pages, which they can select using the gesture-based or button-based interaction methods.
