Description: Gaze-Based Interaction refers to techniques that use gaze tracking to enhance user experience in various technological applications. This form of interaction allows devices to interpret the user’s gaze direction, thus facilitating navigation and control of interfaces without the need for physical contact. Through cameras and sensors, it can accurately track where a user is looking, opening up a range of possibilities in designing more intuitive and accessible interfaces. This technology is based on the principle that gaze can be a powerful indicator of user attention and intent, allowing systems to respond more effectively to their needs. Gaze-Based Interaction not only improves accessibility for people with disabilities but can also enrich the user experience in virtual and augmented reality environments, where natural interaction is crucial. Its use is also being explored in marketing and advertising, where understanding where a consumer looks can provide valuable insights into their preferences and behaviors. In summary, Gaze-Based Interaction represents a significant advancement in how humans interact with technology, making interfaces more natural and aligned with how we perceive the world.
History: Gaze-Based Interaction has its roots in eye-tracking research that began in the 1960s. However, it was in the 1990s that the first practical applications were developed, thanks to advances in camera technology and image processing. In 1996, the eye-tracking system ‘GazeTracker’ was one of the first to be used in research settings. Since then, the technology has evolved significantly, with the introduction of more compact and precise devices in the 2000s, allowing its use in a variety of fields, from healthcare to advertising.
Uses: Gaze-Based Interaction is used in various applications, including accessibility for people with disabilities, where it allows control of devices through gaze. It is also applied in virtual and augmented reality environments, enhancing user immersion. In marketing, it is used to analyze consumer behavior, allowing companies to better understand their customers’ preferences. Additionally, its use is being explored in education, facilitating interaction in digital learning environments.
Examples: An example of Gaze-Based Interaction is the eye-tracking software used in usability research, which allows researchers to see where users look on a screen. Another example is the use of devices like the Tobii Eye Tracker, which allows users to control applications and video games with their gaze. In advertising, some companies have used eye-tracking technology to analyze which ads capture consumers’ attention the most.
