Unity developers, what to do?

Question

Unity

Hello everyone. I need help or have a question about Unity development. I recently started learning Unity and did a little augmented reality project. The essence of the project is that when the camera sees a letter on a sheet, a 3D object appears above the sheet. Made it on the Vuforia framework. I have an idea to expand the project: when let's assemble a word from these letters on a sheet, the camera should recognize the word and display it on the screen, and the application could, for example, search for this word in the database and return a model / drawing for this. Is it possible? Please advise where to start or what to do.
Upd. I heard about machine vision, who will say if this algorithm is suitable?

Answer 1

You make targets for each letter in the vuforia, in the update you take a list of recognized targets, sort them by position on the x-axis in screen space, replace the targets with letters, get a word, and then do whatever you want.
