The present invention relates to a mixed reality device for the purpose of quantifying and improving the sense of equilibrium for the treatment of dizziness and a method of performing the same. More specifically, it measures the movement of the eye and is damaged or functioning in the vestibular system. The apparatus for finding diminished parts and for providing a patient with an exercise method suitable for the degree of injury and the degree of function reduction, and for providing an evaluation for correctly performing the proposed exercise method. The present invention relates to a mixed reality device and a method of performing the same for the purpose of quantification and improvement.

In general, the frequency of dizziness more than once in a lifetime is 10-20%, more than 50% over 60 years old. According to the 2010 National Nutrition Survey, more than 30% of Koreans aged 65 or older felt severe dizziness more than once a year. However, the reality is that the diagnosis and treatment of dizziness is not yet active.

Dizziness can range from simple stress, inner ear disease, or stroke to a variety of causes, including subjective complaints such as acute, dazed, shaken, back, or floating. The most important body organs are the vestibular organ and vestibular nerve in the inner ear, the nerves in the brain, including the cerebellum and brain stem, the visual and eye movement nervous systems including the eyes. It is difficult to quantify the symptoms because the organs involved are widespread in the body, and it is important to find and cure the obvious causative diseases, but the symptoms rarely disappear completely with surgery / drug treatment. As in other diseases, proper rehabilitation should be followed after surgery / drug treatment.

Recently, due to the development of IT technology, the medical field is actively performing surgery or education using virtual / augmented reality. In patients with hemiplegia due to brain injury, exercise methods using virtual reality devices help to improve patient compliance through motivation and interest, and primitive virtual reality exercise services using TV screens have been commercialized overseas.

The virtual / augmented reality device currently being developed for games, etc. is an effective device for stimulating a wide range of nervous systems related to dizziness and outputting a response.

The importance of rehabilitation treatment is already known to dizziness patients, but domestic hospitals are unable to prescribe rehabilitation treatment for each individual's symptoms and causes due to lack of labor, shortage of medical service, and short medical time. In some cases, the traditional exercise method is introduced through the distribution of invitations, but due to lack of motivation and lack of interest, it may be hardly implemented. Therefore, a more interesting and easy rehabilitation exercise device is needed. Had a problem.

Accordingly, the present invention is to solve the conventional problems as described above, the object of the present invention relates to a mixed reality device for the purpose of quantification and improvement of the sense of equilibrium for the treatment of dizziness, and a method of practicing the rehabilitation By using the device to check the function of the nervous system related to the impaired sense for each individual, it is possible to personalize the training centered on this, and also to accurately and artificially give the stimulus that can be given to the individual during the treatment and to the programmed stimulus Mixed reality device for the purpose of quantifying and improving equilibrium sensation for dizziness treatment that can motivate and induce interest by providing rehabilitation exercise intuitively by checking individual responses It is intended to provide a method of execution.

As described above, by using a mixed reality device and a method of performing the same for the purpose of quantifying and improving the sense of equilibrium for treating dizziness according to the present invention,

The augmented / virtual / mixed reality device, which is a virtual reality device, is an effective way to give a visual stimulus to a patient's entire field of vision in three dimensions, and can arbitrarily adjust a target to fix an eye and move head and body. Has the effect as a device that can detect the desired motion and induce the desired exercise,

It can be stimulated by artificially controlling the vestibular system, somatosensory system, and visual system of the nervous system of the human body at the same time, and furthermore, it is possible to induce interest and motivation, so it is optimized for use as a rehabilitation exercise device for dizziness improvement and treatment Can have an effect.

In addition, the game-type rehabilitation program has the effect of inducing head and body movements while continuously providing visual stimulation. Both in-hospital devices and portable devices for home care are available, plus a four-dimensional device with somatosensory devices on the feet and legs can provide an ideal vestibular rehabilitation device for all the sensory stimuli of the whole body. It is effective.
