An apparatus configured to perform object recognition is provided that includes a camera, an assistance feedback device, and processing circuitry. The processing circuitry may be configured to receive the plurality of images from the camera and repeatedly determine characteristic features within the plurality of images and compare the characteristic features within the plurality of images to an object identification dataset to determine object matches for identified objects within the plurality of images. The processing circuitry may be further configured to determine a name for identified objects from the object identification dataset, output, using the assistance feedback device, a position indicator for identified objects, and output the name of identified objects within the assistance feedback device field of view.

Object recognition and presentation for the visually impaired

Apparatuses, systems, and methods for object recognition and presentation are provided. An example apparatus may include a camera, an assistance feedback device, an input device, and processing circuitry. The processing circuitry may be configured receive an image from the camera, compare characteristic features within the image to an object identification dataset to identify object matches for a plurality of objects within the image, receive a selected name of an identified object from the user via the input device, and transmit assistance feedback to the user indicating a position of the selected object within the field of view via the assistance feedback device.

An observation system for viewing light-sensitive tissue includes an illumination system configured to illuminate the light-sensitive tissue, an imaging system configured to image at least a portion of the light-sensitive tissue upon being illuminated by the illumination system, and an image display system in communication with the imaging system to display an image of the portion of the light-sensitive tissue. The illumination system is configured to illuminate the light-sensitive tissue with a reduced amount of light within a preselected wavelength range compared to multispectral illumination light, and the image of the portion of the light-sensitive tissue is compensated for the reduced amount of light within the preselected frequency range to approximate an image of the light-sensitive tissue under the multispectral illumination.

Programmable multispectral illumination system for surgery and visualization of light-sensitive tissues

An apparatus for improving performance of a retinal implant may include processing circuitry. The processing circuitry may be configured to receive image data corresponding to a camera field of view, determine whether a particular object is detected within the camera field of view, perform image data processing to enable a representation of a portion of the image data corresponding to an implant field of view to be provided on a retinal implant where the implant field of view is smaller than the camera field of view, and, responsive to the particular object being located outside the implant field of view, provide a directional indicator in the implant field of view to indicate a location of the particular object relative to the implant field of view.

Face detection, augmentation, spatial cueing and clutter reduction for the visually impaired

An illumination system includes a light source, an optical waveguide that has a proximal end and a distal end such that the proximal end is arranged to receive light from the light source and the distal end is suitable to illuminate an object of interest; and an optical coupler constructed and arranged to couple light from the light source into the optical waveguide. The optical coupler includes a reflective surface that reflects at least some light diverging from the light source to be coupled into the optical waveguide.
