This innovative device, a haptic vest, utilizes vibrations too guide visually impaired dogs safely, providing a new level of independence. The project highlights remarkable engineering, including a custom circuit board and vision-processing capabilities, offering a safer navigation solution and emphasizing human-animal bond. News Directory 3 is proud to share this uplifting story. Discover how this ingenious solution can possibly revolutionize navigation for visually impaired canines.
Rice University students Design Haptic Vest for Blind Dogs
Inspired by Kunde, a Houston dog who lost his sight, Rice University engineering students have developed a high-tech vest to aid visually impaired dogs. The wearable technology aims to provide a safer and more autonomous way for these animals to navigate their surroundings.
Grant Belton and AJ Price, Kunde’s owners, approached Rice University’s oshman Engineering Design Kitchen seeking a solution for their dog’s glaucoma-induced blindness. Four students, Adam Vuong, Cristiana De Sousa, Issy Tsai, and Santiago Brent, formed “Kunde’s Friends” to tackle the challenge.
The team created a lightweight vest that uses vibrations to warn the dog of obstacles. Linear resonant actuator motors, similar to those in smartphones, vibrate at varying intensities based on an object’s proximity. This innovative approach to wearable technology replaces the need for physical contact with obstacles.
Stereoscopic cameras mounted near the dog’s head capture real-time depth information. A custom-printed circuit board and vision-processing computer analyze this data, triggering corresponding vibrations in the vest.
Tsai, a freshman electrical engineering major, said the cameras create a depth map, “Kind of like giving Kunde a second set of eyes.” She added that the closer the obstacle, the stronger the vibration.
The team focused on creating a pleasant, durable, and effective device. They had to carefully integrate sensitive electronics without causing overheating or adding excessive weight, while also ensuring the vest could withstand Houston’s climate and Kunde’s playful nature. de Sousa, a junior mechanical engineering student, described it as “a real exercise in creative problem-solving” to embed electronics into a breathable, soft, and rugged vest.
Brent, a junior electrical engineering major, spearheaded the stereo imaging and data processing. vuong and De Sousa concentrated on system integration and vest design. Tsai optimized the vibration motors for efficiency and minimal bulk.
