On Facebook, Instagram, Facebook Messenger and WhatsApp, users upload more than 2 billion photos a day, but for blind or visually impaired people, photos on Facebook and other platforms can only be read by screen readers. The "photo" of the word, the image content is never known. Now, through artificial intelligence technology, Facebook wants to “speak†image content to the blind or visually impaired.
The new feature launched by Facebook is called "automaTIc alternaTIve text", which uses machine learning technology to create algorithms to help artificial intelligence learn to recognize image content and feed millions of examples with a correctness of 80. In the case of %, the image is marked so that the artificial intelligence system can recognize the content in the image on the platform and interpret the image through voice. After the automatic text substitution function recognizes the image content, it then uses the iPhone's VoiceOver function to read the photo content to the user in a voice narrative.
Although this function is still in its infancy, it has been able to identify images including vehicles (cars, boats, airplanes), natural phenomena (sunset, snow, ocean), sports (basketball), food, etc. Describe the face features. As in the case of Facebook, if there is a pair of couples wearing sunglasses standing at the beach and smiling (pictured left), then Facebook’s automatic alternative text function will read “two people, smile, Sunglasses, outdoor, water", as for the first picture right, what is read is "pizza, food."
For content that is more sensitive and potentially controversial, such as race, Facebook said it will be particularly careful. If it is not highly grasped, it will not mark such images and avoid disputes.
Currently, the automatic text substitution feature is only available on the iOS platform, and the language part only supports English voice, but Facebook said it will launch and provide more languages ​​on other platforms as soon as possible. Although this feature is still in its infancy, it is undoubtedly a window for the blind or visually impaired to use their social platform.
