Vision-assist devices and methods of detecting a classification of an object
First Claim
1. A vision-assist device configured to be worn by a user, comprising:
- at least one image sensor for generating image data corresponding to a scene;
a processor, wherein the processor is programmed to;
receive the image data from the at least one image sensor;
perform object recognition on the image data to determine a classification of a detected object that is present within the scene;
determine a confidence value with respect to the classification of the detected object, wherein the confidence value is based on a confidence that the classification of the detected object matches an actual classification of the detected object; and
generate an auditory signal based on the confidence value; and
an audio device for receiving the auditory signal from the processor and for producing an auditory speech message configured to be heard by the user from the auditory signal, wherein the auditory speech message is indicative of the classification of the detected object and a qualifying statement associated with a sub-increment comprising the confidence value.

Abstract
Vision-assist devices and methods are disclosed. In one embodiment, a vision-assist device includes an image sensor for generating image data corresponding to a scene, a processor, and an auditory device. The processor is programmed to receive the image data from the image sensor, perform object recognition on the image data to determine a classification of a detected object that is present within the scene, and determine a confidence value with respect to the classification of the detected object. The confidence value is based on a confidence that the classification of the detected object matches an actual classification of the detected object. The processor further generates an auditory signal based on the confidence value. The audio device receives the auditory signal from the processor and produces an auditory message from the auditory signal. The auditory message is indicative of the classification of the detected object and the confidence value.

13. A method of detecting a classification of an object comprising:
-
receiving image data of a scene from at least one image sensor configured to be worn by a user; determining from the image data, by a processor, a classification of a detected object that is present within the scene; determining a confidence value with respect to the classification of the detected object, wherein the confidence value is based on a confidence that the classification of the detected object matches an actual classification of the detected object; and producing an auditory speech message configured to be heard by the user that is indicative of the classification of the detected object and a qualifying statement associated with a sub-increment comprising the confidence value. - View Dependent Claims (14, 15, 16, 17, 18)

19. A vision-assist device configured to be worn by a user, the vision-assist device comprising:
-
at least one image sensor for generating image data corresponding to a scene; a processor, wherein the processor is programmed to; receive the image data from the at least one image sensor; perform object recognition on the image data to determine a classification of a detected object that is present within the scene; determine a confidence value with respect to the classification of the detected object, wherein the confidence value is based on a confidence that the classification of the detected object matches an actual classification of the detected object and the confidence value is selected from a confidence value range on a confidence value scale including a plurality of sub-increments respectively spanning a plurality of confidence values on the confidence value scale and respectively associated with an audio speech description comprising a qualifying statement; and generate an auditory signal based on the confidence value and a sub-increment comprising the confidence value; and an audio device for receiving the auditory signal from the processor and for producing an auditory speech message configured to be heard by the user from the auditory signal, wherein the auditory speech message is an audible voice message configured to be heard by the user and is indicative of the classification of the detected object, the confidence value, and the qualifying statement associated with the sub-increment comprising the confidence value; wherein the processor of the vision-assist device is programmed to store in a memory communicatively coupled to the processor at least one of the classification of the detected object, the confidence value of the detected object, and image data of the detected object based on positive user feedback to the auditory speech message.
