Abstract
A vision-assist device may include one or more sensors configured to generate data corresponding to one or more objects present in an environment, and a processor communicatively coupled to the one or more sensors. The processor is programmed to identify one or more objects present in the environment based on the data generated by the one or more sensors, classify the environment based on the one or more identified objects, and modify at least one parameter of the vision-assist device based on the classification of the environment.
Claims20
A wearable vision-assist device configured to be wearable by a visually-impaired user about a neck and shoulder region of a visually-impaired user, the wearable vision-assist device comprising:
- an image sensor configured to generate image data corresponding to an environment surrounding the wearable vision-assist device;
- a location sensor configured to generate location data corresponding to the environment;
- an audio device;
- a tactile feedback device;
- a processor communicatively coupled to the image sensor, the location sensor, the audio device, and the tactile feedback device, the processor being programmed to:
- identify a first object and a second object present in the environment based on the image data;
- identify a preliminary classification of the environment based on the first and second objects using an object correlation algorithm;
- and
- modify a setting of the audio device or the tactile feedback device of the wearable vision-assist device based on the preliminary classification of the environment based on the first and second objects;
- determine a classification of the environment based on at least the preliminary classification and the location data;
- and
- in response to the environment classification, modify an allocation of a processing capacity of the processor via a modification of allocation with respect to and between at least the audio device and the tactile feedback device, wherein the modification of allocation is based on the environment classification.
