I'm always wondering what my dog is up to when I'm not around. Now computer scientists have developed a special harness that might tell me.
Fitted with sensors, the harness tracks a dog's position and body language. It even collects information such as heart rate and body temperature, which are good indicators of emotional state.
The inventors think it's useful for handlers of assistance dogs, which are trained not to show signs of stress or excitement. Handlers can communicate with their dog through small vibrations in the harness. It's also great for nosy dog owners like me.
