Abstract
Official abstract text for this publication.
The present invention is an improved visual prosthesis including a video processing unit with user controls optimized for use by blind individuals. The controls include easily identifiable shapes. The controls are programmable to provide improved usability with a simple tactile interface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A visual prosthesis comprising: a camera receiving a video image and sending a video signal; a video processing unit, receiving the video signal and converting the video signal to stimulation patterns including a processor circuit altering the video signal according to user input, a housing enclosing the circuit, an indented portion in the housing configured to be identified by touch, a programmable slider within the indented portion for providing user input, the programmable slider programmable to control brightness; a transmitter receiving stimulation patterns from the video processing unit and sending the wireless signals; and an implantable portion receiving the wireless signals and suitable to stimulate visual neurons. 2. The visual prosthesis according to claim 1 , wherein the indented portion includes a beveled indentation. 3. The visual prosthesis according to claim 1 , wherein the indented portion is oval in shape. 4. The visual prosthesis according to claim 1 , wherein the housing includes tactile features in assist a blind person in orienting the housing and locate the user controls. 5. The visual prosthesis according to claim 1 , wherein the programmable slider is a variable resistor with an output connected to an analog digital converter. 6. The visual prosthesis according to claim 1 , wherein the programmable slider is a potentiostat. 7. The visual prosthesis according to claim 1 , wherein the programmable slider is programmable to control gain. 8. The visual prosthesis according to claim 1 , wherein the programmable slider is programmable to control sensitivity. 9. The visual prosthesis according to claim 1 , wherein the programmable slider is programmable to control exposure. 10. The visual prosthesis according to claim 1 , wherein the programmable slider is programmable to control contrast. 11. The visual prosthesis according to claim 1 , wherein the programmable slider is programmable to control zoom.
