This app has been tested on the Nexus 4 and Nexus 5 phones. The convolutional neural network inside the app can understand 1000 classes based on ImageNet classes. The app has been downloaded by over 26k users (as of Oct 2018). This app has been said to “represent the New Frontier of Assistive Technology” by the Massachusetts Association for the Blind and Visually Impaired and has also been called “Shazam for the world around you” by Fast Company Magazine. When using this app the user will wave the phone around you until you feel it vibrating more and more which means you are getting closer to an object it understands.
I developed an Android app for the blind that tells the user what the camera is looking at and vibrates based on how confident it is. In 2015 the ability to perform object classification locally on a cell phone allowed for a new kind of tool for the blind to be developed.
