The Information Presenter is a combined online-desktop software system that displays information to users. In education, it serves as a mnemonic matrix system that can help students learn, maintain their knowledge, find gaps in it and resolve them, as well as understand the material. The desktop component enables students to continuously view thumbnails of loaded information items, which they can open with a single click. This first part examines the system's foundational concepts, terminology, and implementation. It introduces the concept of study notes versus flashcards, examines existing software solutions, and provides a detailed technical overview of the Information Presenter's components, security features, and administrative capabilities. The paper establishes key definitions and frameworks that differentiate the Information Presenter from other educational software tools.
