Description: Interactive overlay is a fundamental concept in augmented reality that refers to the ability to overlay digital elements onto the real world in such a way that the user can interact with them. This digital layer not only enriches the perception of the physical environment but also allows users to manipulate and modify those virtual elements in real-time. Interactive overlay combines graphics, sounds, and other sensory data to create immersive experiences that can be customized according to user preferences. Through devices such as smartphones, tablets, or augmented reality glasses, users can see and interact with virtual objects that appear to be integrated into their physical surroundings. This technology enhances the visualization of information and encourages active user participation, transforming the way we interact with the world around us. Interactive overlay has become a powerful tool in various fields, from education to entertainment, enabling experiences that were once unimaginable.
History: Interactive overlay has evolved from early augmented reality experiments in the 1960s when Ivan Sutherland developed the first virtual reality system. However, it was in the 1990s that more practical applications began to emerge, such as Boeing’s data visualization system. With the advancement of mobile technology and improved sensors, interactive overlay gained popularity in the 2010s with the release of applications like Pokémon GO in 2016, which brought augmented reality to a mass audience.
Uses: Interactive overlay is used in various applications, including education, where it allows students to interact with 3D models of complex concepts. In the entertainment sector, it is employed in video games and mobile applications that combine the real world with virtual elements. It is also used in industry, for example, in data visualization and employee training through interactive simulations.
Examples: A notable example of interactive overlay is the Pokémon GO app, which allows players to capture virtual creatures in the real world. Another example is the IKEA Place app, which enables users to visualize furniture in their home before purchasing it, overlaying 3D models in their physical environment through their device’s camera.
