  They tried that until they realized that there were plenty of reddit mods who would pay them to remote control the spray if they put a little camera in there. >

  Hmm, there are a couple of approaches I can see:
  
  Simple IR map looking for the hole, this could potentially be easy if they have high enough resolution. 
  Image recognition, this would mean creating a dataset with a LOT of feces stained buttholes and somebody would need to identify which spot is it. 
  Set up a training model on a test rig, then use human testers to 'reward' the system when they have it right. Over time the model should be stable and ready to be shipped
  Build the model with real data from 1 or 2. Potential privacy nightmare
  'Low' tech solution, save the setting each time people sit on the seat, detect weight distribution and whether people adjusted the pressure / angle. 
  
  All in all, really depends on budget constraints and what type of sensors are available to the company. >
  
  I don’t see why the buttholes would need feces in the pics. I assume smart bidets are just directing the spray at the butthole, not checking to see if there’s fecal matter left/highest concentration
