Abstract
The video wall technology has many useful applications. However, the high cost of the video wall might make it unavailable when needed. The PiWall is a low-cost alternative for a traditional video wall. The PiWall project was built to meet very specific requirements, and therefore it has very limited applications. The most recognizable problem on the current system is that it needs to restart every time when a change on content being displayed is needed. Developing the PiWall system will widen the scope of its applications. The path to developing an enhanced PiWall system starts by examining the existing PiWall system and understanding its current limitations. Then defining the new requirements. After that proposing the design of the system. In addition, analyzing the source code and understanding how the system works. The next step is building the current system, and then gradually adding features and improvements. At the end, it is expected to have an improved PiWall system that has a variety of useful applications.
