Machines are now being trained to be attentive to shape, texture and sweetness. These decisions up to now have been made by experienced workers. Blueberries for example have a standard color palette and are very delicate so they can bruise easily. BBC Technologies of New Zealand has invented machinery that can separate blueberries by color and size which until now was time consuming and done by workers with nimble hands. The software takes from 2400 individual images of what a firm and proper color of a blueberry should look like. The color can also determine the sweetness which is another factor on how they are priced and packaged. Artificial intelligence can distinguish the difference from a stem hole and that which has been pecked by a bird and will soon rot. It can separate fruit that should be eaten within a week as opposed to the berries that can travel longer distances. PepsiCo is teaching machines sensory perception. Lasers are bounced off of potato chips to capture the sound of crunchiness in order to replicate someone biting into a potato chip. I wonder if the day will come when we walk into our home and see a machine sitting on our couch munching on chocolate chip cookies.
