Description: Gaze interaction is a method of interaction that allows users to control elements in a digital environment simply by looking at them. This approach is based on eye tracking technology, which detects the user’s gaze direction and translates that information into commands or actions within an interface. Gaze interaction has become a powerful tool in the fields of augmented reality (AR) and virtual reality (VR), where immersion and natural interaction are fundamental. Through this technique, users can select objects, navigate menus, or activate functions without the need for traditional input devices like mice or keyboards. This not only enhances the user experience but also allows for a more intuitive and fluid interaction, especially in environments where hands may be occupied or where a more immersive experience is sought. Gaze interaction can also be used to gather data on user attention and interest, which can be valuable in various research and marketing applications. In summary, this form of interaction represents a significant advancement in how users engage with technology, making the digital experience more accessible and natural.
Uses: Gaze interaction is used in various applications, especially in the fields of augmented reality and virtual reality. In virtual reality, it allows users to interact with three-dimensional environments more intuitively, facilitating object selection and navigation in virtual spaces. In augmented reality, it is employed to overlay digital information onto the real world, enabling users to interact with virtual elements simply by directing their gaze at them. Additionally, this technology is used in areas such as market research, where consumer attention is analyzed, and in accessibility, helping individuals with disabilities interact with digital devices.
Examples: A practical example of gaze interaction can be found in virtual reality devices where users can select objects in the virtual environment simply by looking at them. Another case is the use of eye-tracking technology in marketing applications, where researchers study how consumers visually interact with advertisements and products. Additionally, in the field of accessibility, there are systems that allow individuals with limited mobility to control computers and devices through gaze tracking.
