Rice University students create a high-tech vest to assist blind dogs in navigating

Rice University students craft a vest to help blind dogs safely navigate using haptic technology and cameras.

: A group of Rice University students developed a high-tech vest to aid blind dogs like Kunde, who became sightless due to glaucoma, in navigating safely. The vest employs vibration motors and stereoscopic cameras to alert dogs to obstacles by varying vibration intensity based on proximity. This innovative device, created by students Adam Vuong, Cristiana De Sousa, Issy Tsai, and Santiago Brent, demonstrates potential for broader applications in medical support and rehabilitation. The project involved complex engineering to ensure the vest's comfort, durability, and ability to function in challenging environments, such as humid weather.

Rice University engineering students crafted a unique high-tech vest designed to aid blind dogs in navigating their environment without fear or frustration. Kunde, a playful dog belonging to Grant Belton and AJ Price, lost his sight to glaucoma, prompting this innovative project. This vest could potentially transform the lives of visually impaired animals, offering new freedom without the discomfort associated with traditional aids.

X's status involves cutting-edge collaboration and creative problem-solving demonstrated by Adam Vuong, Cristiana De Sousa, Issy Tsai, and Santiago Brent, collectively known as Kunde's Friends during this project. Their approach uses a lightweight vest equipped with linear resonant actuator motors and stereoscopic cameras, creating a dynamic feedback system for the dog. The setup allows for real-time depth analysis and vibration alerts, simulating a second set of eyes for the animal, according to freshman Tsai, responsible for the motor control system.

The vest’s design balances comfort, weight, and durability, crucial for maintaining the dog’s playfulness and ensuring it can withstand Houston's hot, humid climate. As De Sousa remarked, the team faced the challenge of embedding electronics in a wearable, breathable, and rugged form. This design is not only a prototype for assisting animals like Kunde but also a model for wearable technology applications in human rehabilitation, where real-time feedback can aid therapy.

The team exhibited their work at the 2025 Huff OEDK Showcase in April. Their project highlights the potential for easily scalable designs by using open-source machine learning and affordable, widely available electronics. The vest currently boasts a range of up to eight meters with a battery life of about two hours, promising a future with fewer collisions and more freedom for Kunde.

This innovation story highlights broader implications for wearable tech in various domains, from medical assistance to consumer electronics. The students’ achievement is a testament to Rice University's commitment to translating academic knowledge into practical solutions. With emerging technologies and creative problem solving, devices like this vest might soon extend to a variety of applications, enhancing the quality of life for both animals and humans.
