Navigating large college or school campuses can be challenging, particularly for new students, visitors, or those with limited mobility. Indoor navigation can be particularly difficult due to the complex and multi-level nature of many campus buildings. Traditional navigation methods, such as printed maps or signage, can be difficult to interpret and may not be available in all areas. As a result, individuals may waste time and energy trying to find their way, which can be frustrating and stressful. An indoor navigation app that uses AR technology can solve these problems by providing a more intuitive and personalized navigation experience. The app can use a smartphone's camera and sensors to overlay information on the user's real-world view, including directions, location markers, and points of interest. The app can also adapt to the user's needs and preferences, such as providing accessible routes or highlighting areas of interest. Overall, an indoor navigation app using AR technology can enhance the campus experience for all users, improving accessibility, efficiency, and convenience.
