The AI that can train your dog: Researchers develop smart harness that respond to your dog's body language 
Smart harnesses have a small computer roughly the size of a deck of cards
They also contain array of sensors to monitor posture and body language
 When proper behaviour is detected, algorithm triggers release of a treat  

Researchers have developed a computer system that can train dogs without the help of a human.
The team from North Carolina State University developed a harness which contains an array of sensors to monitor posture and body language.
Using a small built-in computer to transmit data, the system can give out rewards for correct behaviour by releasing a treat from a nearby dispenser.

HOW IT WORKS 
Researchers from North Carolina State University developed a harness which contains an array of sensors to monitor posture and body language.
Each harness also has a small computer, roughly the size of a deck of cards.
The tiny computer transmits data from the sensors wirelessly, and when the proper behaviour is detected, the algorithm triggers a 'beep' and releases a treat from a dispenser nearby.
While the algorithm proved to be highly accurate, rewarding the correct behaviour 96 percent of the time, the human trainer still performed better, with an accuracy rate of 100 percent.
But, the algorithm was consistent in its response time, while the times of the human trainer varied.
Researchers say consistency is a critical component of training.
Each harness has a small computer, roughly the size of a deck of cards.
This works in conjunction with the harness's built-in sensors and a custom algorithm that triggers the rewards.
In order to fine-tune the algorithm to optimize speed and accuracy, the researchers worked with 16 volunteers and their dogs, comparing the performance of the algorithm with the timing and accuracy of a human trainer.
'Our approach can be used to train dogs efficiently and effectively,' says David Roberts, an assistant professor of computer science at NC State and co-author of a paper on the study.
'We use sensors in custom dog harnesses to monitor a dog's posture, and the computer reinforces the correct behaviour quickly and with near-perfect consistency.'
Researchers had the system reward dogs for correctly moving from a standing to sitting position.
