摘要:
The invention provides a system for artificial retinal prosthesis with color vision comprising an artificial retinal prosthesis implanted in a user's body. The artificial retinal prosthesis comprises a plurality of pixel units and a color shutter integrated with the plurality of pixel units structurally. The plurality of pixel units are used to receive an external visual image that enters the eyes of the user, and output a spatiotemporal electrical stimulation to the user's optic nerve according to the external visual image. The color shutter connects with the plurality of pixel units, and determines a spectrum that is allowed to enter the eyes to allow the user to generate a color image perception. By allowing stimulation of the artificial retinal prosthesis to vary with different spaces and times, and synchronously controlling the spectrum that is allowed to enter the eyes, thereby assisting the patient in obtaining color visual perception.

Examples are disclosed that relate to a head-mounted device configured to perform virtual echolocation. The head-mounted device is configured to cast an array of rays at specified angles from a position derived from a pose of the head-mounted device in a physical environment, identify a plurality of intersection points of the rays with a virtual model of the physical environment, for each identified intersection point, modify an audio signal based on a head-related transfer function corresponding to the intersection point to produce a plurality of spatialized audio signals, for each spatialized audio signal, determine a time-of-flight adjustment based upon a distance between the corresponding intersection point and the position from which the rays were cast, and output each spatialized audio signal to one or more speakers with a delay based on the time-of-flight adjustment.

A wearable image manipulation system comprising a camera input system, an image projection system, where the image projection system is capable of being worn by a user, and a processor in communication with the camera input system and the image projection system such that the processor is capable of receiving an image from the camera input system, modifying the image to produce a modified image, and displaying the modified image on the image projection system. The camera input system may comprise a contact lens with a camera mounted thereon. Additionally or alternately, the system may be capable of tracking a user's eye movement to accurately capture where the user is looking with the camera input system.

Devices and a method are provided for providing feedback to a user. In one implementation, the method comprises obtaining a plurality of images from an image sensor. The image sensor is configured to be positioned for movement with the user's head. The method further comprises monitoring the images, and determining whether relative motion occurs between a first portion of a scene captured in the plurality of images and other portions of the scene captured in the plurality of images. If the first portion of the scene moves less than at least one other portion of the scene, the method comprises obtaining contextual information from the first portion of the scene. The method further comprises providing the feedback to the user based on at least part of the contextual information.

Intraocular apparatus is provided, having an anterior side and a posterior side, and configured for use with an extraocular imaging device. The intraocular apparatus includes a photovoltaic energy receiver, or an RF energy receiver, on the anterior side which receives energy from outside the eye to power the intraocular apparatus. Additionally, the intraocular apparatus includes a photodiode on the anterior side of the intraocular apparatus which receives data from the extraocular imaging device. An application-specific-integrated-circuit (ASIC) is positioned on the posterior side of the intraocular apparatus and includes (i) circuitry configured to process the data from the photodiode into an image, (ii) an electronic display, e.g., a light-emitting diode (LED) display, which emits light representing the image, and (iii) at least two through-silicon vias connecting the ASIC to the photovoltaic energy receiver and to the photodiode. Other applications are also described.

Methods, systems, and products estimate distances to aid a visually impaired user of a mobile device. As the user carries the mobile device, a camera in the mobile device captures images of a walking cane. The images of the walking cane are analyzed to infer a distance between a tip of the walking cane and the mobile device. The distance may then be used by navigational tools to aid the visually impaired user.

A system for producing a depiction of an image is provided. The present invention includes camera operable to capture an image and a laser projector operable to project a laser beam in an x and y direction. The present invention further includes a computer having a microprocessor and a memory. A software may be saved on the memory and may operate the computer to scan the image to locate edges of objects depicted in the image and direct the laser projector to project the laser beam along x and y coordinates of a plane. The x and y coordinates outlines the edges of the objects and thereby forms the depiction of the image.

A method of representing visual images by alternative senses is provided herein. The method includes the following stages: obtaining an image of an environment having a background and physical objects distinguishable from the background; slicing the image into a plurality of slices; identifying, for each slice at a time, and slice by slice in a specified order, if at least a portion of the physical objects being contained within the slice; applying, in the specified order, a conversion function to each identified portion of the physical objects for generating a sound or tactile object-dependent signal; associating a sound or tactile location-dependent signal unique for each slice; superpositioning, in the specified order, each object-dependent signal with a respective location-dependent signal for creating a combined object-location signal; and outputting the combined object-location signal to a user via an interface in a form usable for a blind or visually impaired person.
摘要:
Visual impairment, or vision impairment, refers to the vision loss of an individual to such a degree as to require additional support for one or more aspects of their life. Such a significant limitation of visual capability may result from disease, trauma, congenital, and/or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, such as eyeglasses or contact lenses, medication, or surgery. According to embodiments of the invention a method of augmenting a user's sight is provided comprising obtaining an image of a scene using a camera carried by the individual, transmitting the obtained image to a processor, selecting an algorithm of a plurality of spectral, spatial, and temporal image modification algorithms to be applied to the image by the processor, modifying the image using the algorithm substantially in real time, and displaying the modified image on a display device worn by the individual.
