In 2022, ODUS Plus featured cutting-edge computer vision AI and a resilient, user-friendly design.

According to the World Health Organization, an estimated 2.2 million people globally are suffering from a visual impairment or total blindness. Although millions have an inability to see, there is a lack of a practical product on the market which is both cost effective and efficient in assisting the visually impaired population. The Object Detection Universal System Plus (O.D.U.S.+) was designed to be that solution, allowing, and providing the wearer with freedom and safety in movement, as well as extending their capabilities with Computer Vision Artificial Intelligence.

The device was programmed with the programming language Python, and utilized two Raspberry Pi microcomputers, 4 ultrasonic sensors, 4 vibration motors, and a camera. O.D.U.S.+ works by collecting distance data using ultrasonic sensors and parsing it to provide alerts if an object is within 3-feet of the wearer, through 3 methods. These alerts are vibrations created by vibration motors on the glove, with data being received over BLE, or Bluetooth Low Energy, a series of beeps from a buzzer, and a computer-generated voice produced through a text-to-speech program. Furthermore, by using the TensorFlow LITE database, coupled with the programming library, OpenCV, the device can accurately describe objects in front of the wearer, providing an added sense of awareness.
