The digital space has had an impact on education through the use of modern technology such as video walls. We discuss what display technology made of LED and LCD screens is, how it’s useful in passing information to students in learning institutions and its features. The information given in this article aims to increase your knowledge on video walls and their importance.
What is a video wall?
A video wall is a combination of multiple video screens to form a large display. The display technologies used include LED and LCD screens, laser and rear projection displays. LED’s are the most common due to their high brightness, seamless nature and flexible design. They are easy to operate using a video controller i.e. hardware-based controller or software-based controller.
Applications for video walls include
- Digital billboards
- Airports
- Academic environments
- Shopping malls and businesses
- Theatres and museums
Features of video walls
-
Hardware
The main hardware in the system are digital display and media player. Digital display involves the LED and LCD screens while the media player is the device that connects to the screen.
-
Software
The content management software (CMS) allows users to have control of their digital signage content. It’s the software’s main platform. The content displayed on the video wall is controlled from here.
-
Content/ information
The content displayed is what the viewers consume and is the most vital element. It may be videos, images or a piece of information.
How are video walls an effective teaching tool?
-
Collaboration
Video walls force schools to move from the traditional lectures and adapt the collaborative-based-model. The model is keen teamwork and problem -solving techniques. A university partners with another in a different location, through the video walls to work on projects or tasks together.
They are effective beyond the classrooms too, in places such as libraries.
-
Enhances interaction
The display technology incorporates 3D data visualization. The optical tracking system enables students to interact during the learning process instead of sitting and listening only. The walls have a handheld user interface that allows the user to be actively involved in the ongoing session. Data visualization plays a huge role in research projects where the skill is required.
-
Develop a strong impression
LED screens attract learners due to their large frame and the size of the content displayed. Video walls can be used on hallways or school entrances to engage students and develop their interest in the institution. Content about the school or what is expected of them can be displayed as a form of interaction. Visitors are able to explore the school content and universities establish personal connections with potential students.
Installing video walls in facilities within the school environment allows display of programs such as sports. They enlighten students about what is available and act as a recruitment tool.
-
Flexibility
Unlike traditional boards which have a permanent location, video walls can be moved to the desired location, to reach its full potential. The location is as essential as the content displayed on the screen. The right display location attracts every student’s attention and ensures full engagement during learning.
Conclusion
At universities or colleges, ensuring proper learning going on is key. Video walls have completely changed the teaching dynamics, and created a whole different experience. Institutions should invest in the technology since it has proved to be of great benefit to both students and teachers.
