Description

The present invention relates to a method for improving the vision performance of a user and to a device suitable therefor.SUMMARY OF THE INVENTIONMuch of the population relies on visual aids. These include, in addition to eyeglasses, contact lenses. Eye physicians and ophthalmic opticians ensure that eye diseases and immunodeficiencys are recognized and corrected or alleviated or overcome with the aid of these visual aids. Nevertheless, there are many vision deficiencies which cannot be corrected with vision aids. This is often due to a malfunction in the interaction of the eyes or to an inadequate processing of the optical information in the brain. Concentration problems and headaches are the result. The problem can be counteracted with a targeted visual training.For example, syntonics light training has been known for more than one century, in which the eyes are stimulated with colored light.Furthermore, the document DE 10 2011 119 361 B4 discloses a device for improving the vision performance, in which a corresponding method is also described. Here, by including attention-forming stimuli such as games, a moving grid composed of grid elements is displayed for improving vision performance. The invention enables measurements to be triggered automatically and also automated data analyses to be carried out. The obtained measurement data can also be made directly usable, whereby the efficiency of improving the vision performance can be increased. However, not all physical effects on vision are observed, so the efficiency of this disclosure is still more enhanced.EP 1 246 596A1 discloses systems and methods for evaluating, quantifying, and improving a person's visual perception capabilities.WO 2017 / 089 903 A1 discloses a method and a system for determining the gaze stability of the patient during head movements of the patient.The invention is based on the object of bringing about a method for increasing the vision performance of a user which is more efficient than comparable methods according to the prior art. In addition, the object is to provide a device for carrying out this method.The object on the process side is achieved with the features of claim 1, wherein dependent claims 2 to 4 describe further embodiments. The solution of the object on the device side is achieved by the device having the features according to claim 5. The further subclaims represent further embodiments of the device.In the method according to the invention for improving the vision performance of a user, a display device is used for displaying at least one moving grid consisting of grid elements, which the user has to look at during the course of the method. The display device displays the moving grid consisting of grid elements. At the same time, the detection of the posture resulting from the center of the body reflecting the visual perception of space takes place by means of at least one pressure sensor. The detection of the user's eye activity is carried out in a common manner during the viewing of the display device by the user, for example by means of an eye tracking system, so that the interaction of the two eyes can be determined. Processing of the sensed posture and eye activity and the determination of improvements in the representation of the moving grid comprised of grid elements is performed. In adapting the representation of the moving grid consisting of grid elements, this is done with regard to shape, size, direction of movement and speed of movement. The direction of the movement of the grid and the speed of movement become noticeable in the posture of the user, so that the pressure sensor responds again here. The measured values can now be detected again several times in order to achieve further improvements in the display. These steps are repeated until a significant improvement in the representation can no longer be determined. Thus, with comparatively simple means, an individual setting dependent on the user can be carried out, with which a maximum success in eye training can be achieved.In one embodiment of the method according to the invention, in addition to the detection of the body movements, a detection of the body resistance on the skin is also carried out. Sensors, e.g. at the wrists, thus sense the status of the autonomic nervous system, which also cannot be without influence on vision. In this case, the control unit uses the detected values of the body resistance to determine the body activity. By means of the possibilities described at the beginning for stimulating the optic organ via colored light, further influence can be exerted on the training of the eyes. For this purpose, when adapting the display, a colored marking now takes place on the display device in addition to the grid. This colored marking stimulates the user's eye, the stimulation resulting from the malposition of the eye (EXO, ESO, heightphoria) and the status of the autonomic nervous system. Thus, red light stimulates the sympatheticus, resulting in an EXO reaction of the eyes, and blue light stimulates the parasympatheticus, resulting in an ESO reaction.According to a further embodiment of the method according to the invention, further body values such as, for example, pulse and ECG are recorded. These may also have an influence on the representation of the moving grid or the colors or other displays, so that it leads to an improvement of the method.According to a further embodiment of the method according to the invention, an audio stimulation of the user additionally takes place. Thus, with the aid of, for example, individualized hearing training after johanses with audio stimulation, visual problems can be influenced. Besides, audio problems are solved.The device according to the invention for carrying out the method according to claim 1 comprises a display device for displaying at least one moving grid consisting of grid elements and at least one gaze detection device for determining the viewing direction of at least one eye and a control unit for controlling at least the display on the display device. In a use position, at least one pressure sensor or at least one pressure sensor plate is connected to the control unit so that the center of the user's body can be detected in order to thus obtain an optimum adaptation of the visual stimulation. The control unit is configured to interpret measurement data of the at least one pressure sensor or of the at least one pressure sensor plate in such a way that the representation of the moving grid consisting of grid elements is adapted. The lattice is adapted individually according to the user's requirements with regard to shape, size, direction of movement and speed of movement.In a particular embodiment of the device according to the invention, the display device is a device for displaying virtual or augmented reality, in particular a pair of VR glasses or an AR display device. With the aid of VR glasses, but also with other display devices from the area of augmented reality, visual functions can be measured. These include, for example, the vision (the vision), malpositions of the eyes in far and near vision and straight-ahead perception.According to a further embodiment of the device according to the invention, a device for detecting the body resistance on the skin is connected to the control unit. These can be sensors on the wrists, with which the status of the autonomic nervous system can be detected.According to a further embodiment of the device according to the invention, further devices for detecting vital values of the body are connected to the control unit. Thus, an ECG can be measured, the pulse can be detected or similar values can be determined which have an influence on the vision abilities.Finally, according to a further embodiment of the device according to the invention, the control unit is a provider-side unit in the form of a server or a cloud server. All other parts of the device are user-side devices, wherein the control unit and user-side devices are connected to one another by means of a data line or data radio connection. It is thus possible that the method can also be used over long distances, so that complicated paths of the user to the eye trainer can be omitted. A central processing unit can perform the calculation more quickly for a large number of users, provided that a corresponding processing power is available. This leads to an improvement in training efficiency.
