Description: Physical interaction in the context of augmented reality (AR) and virtual reality (VR) refers to the user’s engagement with virtual elements through physical movements or gestures. This type of interaction allows users to manipulate and experience digital environments in a more intuitive and natural way, using their bodies as a means of control. In AR, users can interact with virtual objects overlaid on the real world, while in VR, interaction occurs in a completely immersive environment. Technologies that facilitate this interaction include motion sensors, haptic controllers, and eye-tracking devices, which enable a richer and more engaging experience. Physical interaction not only enhances the usability of AR and VR applications but also boosts user immersion and emotional connection with digital content, making the experience more memorable and effective. As these technologies continue to evolve, physical interaction becomes an essential component for the development of applications across various fields, from entertainment to education and professional training.
History: Physical interaction in AR and VR began to develop in the 1960s with the creation of the first virtual reality systems, such as the Sensorama and Ivan Sutherland’s flight simulator. Over the years, technology has advanced significantly, with the introduction of devices like the Nintendo Wii in 2006, which popularized the use of motion controllers. In the last decade, the arrival of devices like Oculus Rift and Microsoft HoloLens has taken physical interaction to new levels, enabling more immersive and natural experiences.
Uses: Physical interaction is used in various applications, including video games, training simulations, education, therapy, and design. In video games, it allows players to interact more dynamically with the environment. In education, it facilitates hands-on learning through immersive simulations. In therapy, it is used to help patients overcome phobias or improve motor skills.
Examples: An example of physical interaction in virtual reality is the game ‘Beat Saber’, where players use motion controllers to hit blocks to the rhythm of the music. In augmented reality, applications like ‘IKEA Place’ allow users to place virtual furniture in their home using their mobile device’s camera, physically interacting with the real environment.
