Guide Dog AR: A Tactile and Auditory Assisting Device Design with the Motif of a Guide Dog for the Visually Impaired

This study introduces "Guide Dog AR," an AR device inspired by the handle of a guide dog's harness. The device and its associated content aim to provide visually impaired individuals with the experience of walking with a guide dog, serving as both a practical tool and a foundation for entertainment. The device offers an augmented walking experience through tactile and auditory sensations. The device was assessed with the factors "effectiveness" and "immersiveness." The evaluation for effectiveness involved creating a simulated virtual path. The level of immersion was evaluated based on how deeply users were engrossed in the augmented content provided by the device. The success rate was determined by how well users navigated this virtual path using the device's feedback. In assessing immersion, in-depth interviews were conducted with visually impaired participants who experienced the virtual path. These interviews compared their experiences to actual walks with guide dogs, discussing similarities, differences, and overall immersion.
