For biomedical professionals the eye tracking systems is known as Video-Oculography (VOG) and Video-Nystagmography (VNG), based on video recording techniques. It replaces formally used Electro-Nystagmography (ENG), which used electrical recording of retina potentials. These systems are used to record involuntary and voluntary eye movements, which provides useful insights for the diagnosis of balance disorders, neurological disorders, psychiatry, and just started to use in the field of ophthalmology, for ocular motility disorders in particular.
The main advantage of FineGaze is NO CALIBRATION and SIMPLICITY of the test. FineGaze is a painless, noninvasive and absolutely a risk-free assessment VOG and VNG system. FinGaze offers a very light weight portable hardware, express test and analysis of ocular and head movements, vestibular function evaluation. It can be also used for s ocular motor training with different customized software designed for specific purposes.
Small video cameras mounted on disposable frame allow to observe and record horizontal, vertical and torsional eye movements along with head movements in light and in darkness, due to infrared (IR) illumination.
Note: Classical VNG devices are not suitable for a number of applications. They are not fully portable and need qualified personnel to operate. Most devices require complicated and time consuming calibration procedures, which, in most cases, are not appropriate for patient's condition. For example, calibration always requires excellent positional fixations, which may not be possible to perform for patients affected by specific disorders such as ocular motility disorders and brain traumas. On the contrary, FingeGaze is a calibration-free device. FineGaze is easy to operate and highly portable, thus can be used not only in specialized centers but also on the field for example on pitch (for concussion), in unconventional research settings.
Due to sophisticated digital signal processing technique, it is possible to create inexpensive, yet accurate system for sport or even consumer use. FineGaze is very convenient for express screening because of portability, ease of use and really affordable price.
