Haptic Information Feedback Given to Handles in Guide Dog Training

In guide dog training, trainers use haptic information transmitted through the handle of the harness worn by the guide dog to understand the dog's state. They then apply appropriate force to the handle to train the dog to make correct judgments. This tactile experience can only be felt between the dog and the trainer, making it challenging to communicate the amount of force applied to others quantitatively. To solve this problem, this study proposes a method for real-time visualization of the force exerted on the handle and quantification of the handle movement through image processing, which can be applied to actual guide dog training.
