DESCRIPTION

PROCEDURE TO CORRECTLY DISPLAY THE DISPLAY OF ELECTRONIC DEVICES WITHOUT USING GLASSES OR OTHER VISUAL CORRECTION INSTRUMENTS BY USERS WHO NEED THEM

OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to a procedure to correctly display the screen of electronic devices without wearing glasses or other visual correction instruments by users who need them, which will be described in detail. later and supposes a remarkable novelty in the current state of the art.

The object of the present invention focuses, specifically, on a procedure whose purpose is to provide a means for users who need glasses to be able to read correctly and clearly see the image shown on the screen of a computer, electronic tablet, telephone or other electronic device, they can do it without them, facilitating their use at any time and situation, especially to those who do not always use them, but only to read or see closely, although without being limited to it, said means consisting, fundamentally, in a software, either from the operating system itself or from the specific computer program, that modifies and distorts the image to adapt it to the needs of a user based on the previously introduced parameters of their specific visual impairment.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the industry sector dedicated to the manufacture of electronic devices and devices with screens.

BACKGROUND OF THE INVENTION

As is well known, it is very common that, in order to read a text or see an image on computer monitors, on electronic tablet screens or on mobile phone screens, many people have to wear glasses or use some kind of corrective lens of your vision.

A very clear example of this is presbyopia or tired eyesight, which affects almost 100% of people over 45 or 50 years old.

For those affected by presbyopia, it is practically impossible to read a text without the corrective lenses, since without them they see everything blurred and without any precision.

A person affected by a disease or vision defect, when he goes to the eye doctor for not being able to read well, an eye exam is done, placing that person at some distance from letters or symbols and putting on glasses where a series of lenses is incorporated that the optician changes until the patient can see them accurately. Based on the built-in lenses, the graduation required by the person under examination is determined. Today, this procedure, in many cases, is replaced by an automatic device that, analyzing the eye in detail, indicates the graduation and specific disease of the

patient.

The fact is that, without the lenses attributed by the optician, the patient can barely read or see a monitor or screen clearly. Although it is common that if you can do other activities without putting on your glasses, you should always have them on hand to use them whenever you want or that you have to read or look at the computer, the electronic tablet and the mobile phone, which is not always comfortable, especially in the case of the mobile, since its use is often carried out in unforeseen places or in circumstances of all kinds in which the glasses are not always at hand.

It is desirable, therefore, to be able to make use of electronic devices by said persons at any time and place without ever having to resort to the use of glasses to be able to see quickly and read the texts on them, being the objective of the present Invention the development of a procedure specifically aimed at it.

On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other procedure or invention of application similar to the one claimed herein is unknown.

In that sense, it is worth mentioning that, as a closest antecedent of the state of the art, currently in the operating system of some electronic devices, there is a section, which is usually called accessibility, where you can set appearance preferences for the letter to be larger, there is more contrast on the monitor or screen, that it is only in black and white or others, but nothing is known to minimize or suppress focus defects or other defects that many people have in their vision to be able to read or see correctly

EXPLANATION OF THE INVENTION

The procedure to correctly visualize the screen of electronic devices without wearing glasses or other visual correction instruments by users who need them that the invention proposes is configured, then, as a novelty within its field of application, since according to Its implementation satisfactorily achieves the stated objectives, the stages thereof and the characterizing details that make it possible conveniently included in the final claims that accompany the present description.

Specifically, what the invention proposes, as noted above, is a procedure that, based primarily on computer software, is intended to provide a means for users who need glasses or other optical corrective instruments to be able to see and read correctly. and with clarity the images of the screen of the computer, electronic tablet or mobile device, can do it without them, thanks to the fact that said software is the one that distorts the image shown so that, depending on the defect or visual deficiency and the graduation of a user concrete, adapt to it.

For this, the necessary data is provided to said software referring to the specific visual deficiency of the user who is going to use it, which is preferably done manually, that is, by entering the corresponding data on the visual defects that This is the subject's eye graduation, as well as the distance at which it will normally be placed to display the screen, since this is an important factor to take into account to adapt the distortion of the

image correctly.

As a result, the image or visible content of the screen is distorted in such a way that the person who has indicated the visual defect and their graduation sees said content correctly without wearing glasses at the indicated distance, which will vary according to the type of device (for example 30 cm for mobile phones), while the rest of the people who can see this screen and have no visual defect or have another will see the content of the same deformed.

Thus, the method of the invention comprises at least one stage where the software deforms the image it shows on the screen of the device in which it is incorporated according to the needs of the user's visual impairment and the distance at which said user is located. from the screen.

Particularly, the following parameters are indicated to the software: type of defect or defects that the user has (hypermetropha, astigmatism, presbyopia, ...), the graduation of the defect or defects in each eye (0.7 diopters, 1 dioptna, ...) and the distance at which, normally, you will look at the screen of the device in question (20 cm, 25cm, ...). Based on all this, and by means of the corresponding calculation, deforms the image by appropriately distorting it to adapt it in such a way that it corrects the image distortion suffered by the user who has provided the data and sees it correctly without glasses or corrective lenses.

It also contemplates the possibility of incorporating, in the software itself and in the device, means, for example, consisting of a laser sensor conveniently associated with the software, to automatically detect the distance at which the user of the screen in

each moment, allowing this to vary according to the circumstance of use and it is not necessary for the user to enter said data previously in a restricted way.

Thus, the procedure optionally also includes a previous stage where the computer software program automatically detects the distance the user is from the screen.

Likewise, it is also provided that, advantageously, the software incorporates means for, from a previous examination based on questions about the correct visualization of alphanumeric signs or symbols shown on the screen, to determine the type of visual impairment and the graduation necessary to correct the vision defects of the user to whom you must adapt the deformation of the image so that you see it correctly without glasses, preventing it from being the one who introduces them previously, since it may be the case that the user himself has varied said deficiency or Do not remember or do not know exactly the graduation you need.

With this, the procedure also includes, optionally, another previous stage where the software performs a vision test to the user and based on it automatically detects the visual impairment to which the image deformation has to be adapted.

Logically, the software is designed to allow the image to be the original one again, or adapt to other needs of a different user, simply by canceling or replacing the distortion parameters introduced, so that other users can normally use the electronic device that incorporates

It should be noted, finally, that the aforementioned computer software that contemplates the procedure is developed as part of the operating system of the electronic device to which it is incorporated, be it the computer, electronic tablet or mobile phone, or it consists of a program or informatic application specifically designed for the purpose that is implemented additionally.

In any case, with the procedure of the invention, it can be avoided that people who routinely use a specific computer or a specific mobile or other electronic device, always have to be with the glasses or corrective lenses on or always have to travel with they are in your pocket to, for example, be able to read your cell phone while eating at the restaurant or doing any other activity.
