Hii everyone, could you please help so when I scan or take a picture it appears a message on the text box. For example I take a picture of a fist so the in the text box will appear "fist", or if I take a picure of an open palm, in the text box will appear "open palm". Thank you so much for you help, have a nice day 
You can try the LookExtension or PersonalImageClassifier to do this. Using these extension you can get a name of that object.
If it's does't work then you can use the PersonalImageClassifier tool where you need to click your own open palm or fist images and train a model then try it.
