Abstract: The "Positional Wedge with mirror" project explores the development and application of a novel optical device designed to assist in the spatial learning, cognitive development, and visual perception of children. This device utilizes a positional mirror wedge—an adjustable, angled mirror structure—that allows for dynamic manipulation of reflected light and images. By altering the angle of reflection, the wedge creates a variety of visual effects that help engage children in activities such as puzzle solving, spatial reasoning, and understanding symmetry and reflection. The primary objective of the project is to create an interactive tool that not only stimulates curiosity and creativity but also enhances children’s ability to understand abstract concepts related to geometry, physics, and visual processing. The wedge can be used in educational settings to aid in learning games, art activities, and problem-solving exercises by offering a hands-on approach to exploring reflection, refraction, and positioning. This research aims to assess the impact of the positional mirror wedge on children's cognitive development, focusing on its ability to improve problem-solving skills, visual-spatial awareness, and critical thinking. Through a series of user studies, the project seeks to understand the effectiveness of this device in both individual and group settings, providing insight into how children interact with optical phenomena and how such experiences can contribute to educational outcomes. Ultimately, the positional mirror wedge is envisioned as a tool that bridges the gap between playful exploration and educational growth, encouraging children to engage with the fundamentals of optics and geometry in an accessible and enjoyable manner.
