Electrooculography (eog)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Electrooculography (EOG) is a technique for measuring the corneo-retinal standing potential that exists between the front and back of the human eye. This method captures eye movements by recording the electrical activity generated as the eyes move, typically using electrodes placed around the eyes. EOG is commonly used in clinical diagnosis, sleep studies, and research to track eye movements, detect neurological disorders, or develop brain-computer interfaces.
Key Features
- Non-invasive method for measuring eye movements
- Uses surface electrodes placed near the eyes
- Records electrical signals generated by eye movement
- Useful in clinical diagnostics and sleep studies
- Provides data on eye movement direction and amplitude
- Relatively simple setup compared to more complex eye-tracking systems
Pros
- Non-invasive and painless procedure
- Relatively affordable and easy to set up
- Effective for detecting various eye movement patterns
- Useful in clinical and research applications
- Can be combined with other diagnostic tools
Cons
- Limited spatial resolution compared to video-based eye trackers
- Susceptible to electrical noise and artifacts from facial movements
- Requires proper electrode placement for accurate results
- Less suitable for high-precision tracking needs
- Potential discomfort or skin irritation at electrode sites
