AI Sign is probably one of the first A.I. / machine learning app that use for recognise American sign language. AI Sign is able to recognise more than 100+ actions (Sign language in word). AI Sign has two modes: 1. Action Recognition mode: User do actions in front of the camera, and then AI Sign will try his best to predict what is your action in terms of American Sign Language. 2. Capture mode: In order to make AI Sign increase its recognition accuracy, we need more data to train our machine learning model. Therefore, we hope you can help us to generate more training data by capturing your actions. Note that we do not capture your images, all the captured data are numeric e.g. 0.1231, 0.2578 etc... Also you upload your data manually via the app. We will not automatically upload your data to our server.
