title: Android app that identify an object
body: <p>Is there any possible way to develop and implement an app that will only show us text message/details on the camera screen:</p>
  
  <ol>
  <li>When we are pointing our devices on that particular object.</li>
  <li>When we have set the distance between the user and the object say 20 metres.</li>
  </ol>
  
  <p>I know we can use image recognition to do this but I was wondering if there is any other feasible approach? Any suggestions would highly appreciated.</p>
  
  <p>Thanks.</p>
