Description:Field of Invention
The information provided concerns head-worn computer devices designed to help the blind. IOT-based ultrasonic waves detect adjacent impediments and alert people with buzzers or vibrations.

The Objectives of this Invention

This invention aims to produce a wearable device for visually impaired and dependent people. The sight-impaired can confidently traverse their environment with a bracelet that generates ultrasonic waves that buzz or vibrate around obstacles. The device was designed to be effective, simple, and light.
Background of the Invention
Eye tracking and registration are used in diagnostics and surgical procedures for the eye. The vast majority of existing solutions are either incompatible with some devices or only function with others. Modern ophthalmic procedures are highly sophisticated and include the use of multiple tools. Current registration procedures may even be rendered useless by some of these impacts. It's not easy to standardize all of the metrics. All corneal procedures, including those performed using microwave deforming devices and femtosecond lasers for cataract surgery, necessitate a completely fixed eye. Each of these procedures requires positioning the treatment area in relation to a suction ring around the eye. Automatic eye treatment with greater placement precision than human approaches is now possible thanks to the suction ring coordinate system. In (US2013/9037400B2), A momentum measurement gadget and an orientation sensor combine to create a virtual jogging stick that serves as a means of navigating predominantly for people with visual impairments. It is capable of recording the three-dimensional positions of new elements that are interesting and uploading them to an international map set of the area, all while providing angle-dependent navigational instruction recommendations to the person. In addition (US2022/0057226A1), A few elements of the invention provide a device that can be worn that can be used to calculate the position of a gadget within a space. It consists of a number of cameras attached to a framework, at least some of which are designed to make it easier for a user to wear the gadget. The number of cameras is positioned and oriented relative to each other on the structure, and at least a single processor is set up to receive image data collected by the plurality of cameras, execute a feature detection process on the image information in order to derive a first the plurality of characteristics from the image information and calculate the device's position in the space-based, at least partially, on the locations associated with the second diversity of characteristics that were gathered from picture data beforehand recorded of the an environment.
In addition (US2016/10667981B2), Head-mounted displays (HMDs) are useful tools, especially those that offer a transparent image of the surroundings. In an effort to maximize the customer experience, the see-through screen's way of displaying data might be a challenging process. To enhance user knowledge, better techniques and systems for delivering material in the see-through interface are needed.
In recent years (Sandhya et al [2021], Perspectives in Communication, Embedded-systems and Signal-processing - (PiCES), Vol. 4, Issue 11, pp. 1-5), The capacity to travel independently is a well-known difficulty for blind or visually impaired people. However, there are many opportunities to augment traditional scanners for information gathering thanks to the increasing variety of portable digital photography equipment with outstanding performance and low cost. A framework for object identification, recognition of faces, news, and reading novels is developed using cameras to provide visual aids. To assist those who are blind, it can be converted to a speech output. To enable visually challenged people to live somewhat independently, they created this system using only one camera to relay live video. In addition (Yadav et al [2022], International Journal for Research in Applied Science & Engineering Technology (IJRASET), Vol.10, Issue V, pp-1-5), The Arduino-based third eye, also known as extra eyesight for the blind, is a combination of software and hardware solutions that uses ultrasonic sound from an ultrasonic sensor and a buzzer to produce a vibration that allows the user to detect objects. The stick that blind individuals use to walk for extended periods of time has an impact on this invention since it is a measure of weakness for weak people. This is a device that can be worn and designed to help the weak and blind walk more effortlessly. Instead of needing to hold anything in their hands while walking, they can wear our creations. The Arduino is a software device that has hardware functions like a buzzer, battery, and more. The ultrasonic sensor's job is to identify objects in their immediate vicinity and give the user a signal through a buzzer that will enable them to arrive at their destination safely.
Summary of the Invention:
The Third Eye for the Blind is a device that enables blind people to live independently by making it possible for them to complete their day-to-day responsibilities in a manner that is less difficult and more self-assured, all while maintaining a high level of safety. This idea for blind people based on Arduino is not only simple, inexpensive, and portable, but it also does not require any form of upkeep.This technology has the capability to scan in all directions and identify impediments, irrespective of the height or depth at which the object is situated. Those who are blind will, with the assistance of this invention, be able to experience what it is like to see and will be able to move around freely and independently without the assistance of another person, provided that the building is constructed in the correct manner.

Detailed Description of the Invention
It is required to establish a method that will bridge the gap between the diagnostic coordinate system and the intra-surgical coordinate system in order to limit the number of errors and uncertainties that are brought about by the application of a suction ring to an eye. This may be accomplished by developing a method that will bridge the gap between the diagnostic coordinate system and the intra-surgical coordinate system. This void is filled by implementations of the invention using a method that will be described in greater detail further down the page; make sure you stay tuned for that! Implementations of the invention are able to be employed in numerous steps of ocular diagnostics and treatments (collectively referred to as ophthalmic care) to determine a consistent eye coordinate system as well as the position of various characteristics within the eye coordinate system. Ophthalmic care is an umbrella term that encompasses all of these individual processes. It is imperative that this idea be retained in mind throughout the course of the surgical process, beginning with the diagnosis and continuing through preparation, the operation itself, and eventually rehabilitation.
The eye coordinate system as well as particular eye features (limbal ring, pupil, iris, sclera vessels, and markers) can be determined from a variety of imaging modalities at a variety of points in time and over a variety of eye conditions in interaction with a variety of tools (such as a suction ring) as well as procedures, which may significantly affect the imaging content. These interactions can take place over the course of a variety of eye conditions. This is something that can be done during the course of many different eye disorders. The process of eye registration can be broken down into a number of discrete registration phases, with each of these processes culminating in a registration result, as one example of how this can be implemented. One of the embodiments is presented here. Next, the results of the numerous registrations are combined into a single result for a combined registration. This results in greater accuracy and overcomes the constraints that were presented by the prior art.
The initial reference image is then used to perform registration with the pre-surgery image, which ultimately results in the first registration result. This first registration result consists of a coordinate connection (or "displacement" in lateral and rotational directions) between the initial reference coordinate system in the initial reference image and the coordinate system (or the location of the eye) in the pre-surgery image. This initial reference coordinate system is located in the first reference image. One way to think of this "displacement" is as a relationship between the coordinate systems of the two images.
In the subsequent phase, a second registration is performed between the pre-surgery image and an "intra-surgery image," which is captured by the surgical device during the surgery, in particular in a state that alters the eye image. This image is compared to the pre-surgery image to determine whether or not any differences exist between the two. This may occur as a consequence of the insertion of a suction ring, the deformation of the eye, the bleeding of the eye as a consequence of accidents, or a combination of these and other causes. It is much simpler to perform a registration between the pre-surgery image and the intra-surgery image than it is to perform a registration between the intra-surgery image and the initial (diagnostic) reference image. This is because the "modalities" or device arrangement (camera, microscope, wavelength of illumination, etc.) are the same for both the pre-surgery image and the intra-surgery image.
These procedures can be summed up and will be referred to as "multi-level registration" in the more thorough explanation of embodiments that is to follow. This is due to the fact that the registration is completed for various combinations of stages of the ophthalmic care method and also due to the fact that these multiple registration steps (or levels) are subsequently integrated in order to generate a more comprehensive registration with a greater level of accuracy. As a result of these factors, registration is carried out for a wide variety of different configurations of the stages that make up the ophthalmic care method. This is because the process of registration is carried out for various combinations of phases that are engaged in the thalamic care approach. This is the reason why this is the case.
The approach of prior art registration will be mentioned once more in order to provide a somewhat more in-depth explanation of the relevance of this strategy. This will be done in order to fulfil the requirements of the prior art registration approach. This is done with the goal of enhancing the reader's comprehension of the material that is being presented. The wide variety of imaging modalities that can be found in diagnostic and/or surgical imaging devices is the primary contributor to the complexity that is currently associated with eye registration in the current state of the art. These many imaging modalities are distinguished from one another, among other things, by differences in the light wavelength, field-of-view, camera resolution, camera location, and integration time. Because the doctor is required to ensure that all patients have comparable eye conditions throughout the procedure, it is common practise for current registration implementations to ignore any differences in the patients' eye conditions, such as deformations, bleeding, or occlusions caused by instruments. This is done because it is common practise for current registration implementations. This is due to the fact that the doctor is obligated to make certain that all of the patients have comparable eye ailments throughout the entirety of the treatment. The support system contributes to the efficient and precise identification of barriers around the device, covering a large area of detection in the process. This contributes to the overall effectiveness of the detection process.
The Arduino-based third eye for blind people" is being developed in order to offer assistance to those who are blind in overcoming their inability to see or have a sense of vision. This device sends out a signal, both audibly and through vibrations, to inform individuals that there is an impending hazard on their route.When any object comes into proximity to the person holding the device, a beeping sound is produced by the device. The volume of the sound produced by the gadgets increases as the distance between them and the object decreases. Vibration is also initiated. Therefore, the devices serve to make the process of detection simpler for blind people, who are unable to perceive the obstacles that are approaching them because they lack eyesight.Ultrasonic pin trig is connected to Arduino UNO pin 7, ultrasonic sensor pin echo is connected to Arduino UNO pin 6, and the option to use the buzzer sound or not is controlled by a switch. The Arduino board will receive its code at the very end of the process.
