Description: Eye-tracking glasses are wearable devices that incorporate advanced technology to track and analyze the user’s eye movements. These glasses are equipped with sensors and cameras that capture gaze direction, blink frequency, and other ocular patterns. Their ergonomic and lightweight design facilitates prolonged use, making them a valuable tool in various applications. The ability of these glasses to interpret visual attention and user interaction with their environment opens up a range of possibilities in fields such as research, medicine, education, and entertainment. Additionally, their integration with specialized software allows for the collection of precise data that can be used for behavioral studies, usability analysis in various interfaces, and the development of assistive technologies for people with disabilities. In summary, eye-tracking glasses represent an innovative intersection between wearable technology and neuroscience, offering a new way to understand and enhance human interaction with the digital and physical world.
History: Eye-tracking glasses have their roots in research on eye movement that began in the 19th century. However, the development of portable devices started in the 1990s when the first eye-tracking systems that could be used in natural settings were introduced. Over the years, technology has significantly evolved, with advancements in miniaturization and precision, allowing for the creation of glasses that are more accessible and functional. In 2005, the first commercial model of eye-tracking glasses was launched, marking a milestone in their evolution.
Uses: Eye-tracking glasses are used in a variety of fields, including market research, where they help understand how consumers interact with products and advertisements. In the medical field, they are used to assess visual disorders and in the rehabilitation of patients with brain damage. They are also valuable tools in education, allowing researchers to study attention and learning in students. In entertainment, they are employed in video games and virtual reality experiences to enhance user immersion.
Examples: An example of eye-tracking glasses is the Tobii Pro Glasses 2 model, which is used in behavioral and usability research. Another example is the EyeLink system, which is used in psychological and neurological studies to analyze visual attention and cognition.
