摘要： The present invention is a depth sensing visual prosthesis. By depth sensing objects within an image, items located at a certain depths from the user can be removed to declutter an image. The resulting image presents only objects within a range of depth from the visual prosthesis user. Depth sensing can be accomplished in various ways including structured light, time of flight, or preferably, a stereo camera pair.

摘要： The invention is a method of automatically adjusting a visual prosthesis electrode array to the neural characteristics of an individual patient. By recording electrically evoked responses to a predetermined input stimulus, one can alter that input stimulus to the needs of an individual patient. A minimum input stimulus is applied to a patient, followed by recording an electrically evoked response to the input stimulus. By gradually increasing stimulus levels, one can determine the minimum input that creates a neural response, thereby identifying the threshold stimulation level. One can further determine a maximum level by increasing stimulus until a predetermined maximum neural response is obtained.

摘要： The present invention is an improved spatial fitting and training system for a visual prosthesis. The system of the present invention maps projected locations of percepts, where a person perceives a percept from a visual prosthesis to the intended location of the percepts. The projected location may vary over time. These test results can be used to correct a visual prosthesis or spatially map the visual prosthesis.
