A portable system that allows blind or visually impaired persons to interpret the surrounding environment by sound or touch, said system comprising: two cameras separate from one another and configured to capture an image of the environment simultaneously, and means for generating sound and/or touch output signals. Advantageously, the system also comprises processing means connected to the cameras and to the means for generating sound and/or touch signals. The processing means are configured to combine the images captured in real time and to process the information associated with at least one vertical band with information relating to the depth of the elements in the combined image.

A wearable device that pulses vibrators located on the user's back with different frequencies based on the distance of objects from the user. This distance is found via distance sensors on the hands and feet. The vibrating element that pulses is determined by the position of each sensor around the user's body. The combination of all these functions allow the wearer to get a sense of their surrounding without having to touch or see anything. The advantages of the device are a person with visual impairments can sense where things are without having to touch anything like all prior art requires and allow them to be totally immersed in their environment.

A method of at-home monitoring of eye conditions using a head mounted display that is capable of establishing a visual model associated with a patient. The visual model may include data related to a quality of the patient's vision. The patient may use the system to establish a visual model periodically, such as daily, and the system may compare the visual model to previous visual models and send an alert to the patient's physician if changes meeting a given criteria are detected. This may allow the physician to immediately take steps to save the patient's eyesight where a delay in treatment may result in vision loss.

Systems of presenting environmental data include a frequency emitting device, a frequency receiving device, wherein the frequency receiving device is tuned to receive a reflected signal from the frequency emitting device, a processor, and a sound emitting device adapted to play a sound transmission. The processor is programmed to compile data from the reflected signal and convert the data from the reflected signal into a sound transmission.

A processing unit includes a direction decision unit and a guide information generation unit. The direction decision unit decides a direction in which a person who behaves without a sense of sight walks. The guide information generation unit generates guide information for the person who behaves without the sense of sight to walk in the decided direction. The present technology is applicable, for example, to a smartphone or the like used by the person who behaves without the sense of sight.

A method of using an intraocular implant device for comprehensive intraocular vision advancement is provided. The implant includes an intraocular implant body shaped for positioning inside a lens chamber of an eye. In some embodiments, the implant includes an optical adjustable base accommodating lens configured to provide both base adjustment and accommodation. In further embodiments, the implant includes a photoelectric sensor operable to receive incident light through the cornea and to convert the received light into electrical energy for use with one or more circuit components disposed on the body, and wherein the photoelectric sensor is also operable to convert the received light into image data. The intraocular implant device may include a projector for projecting an image onto the retina of a user.
