In an exciting development at the University of British Columbia (UBC), stroke survivors in British Columbia are gearing up to test a revolutionary technology designed to boost their recovery and bring back the functionality of their limbs and hands. This groundbreaking endeavor involves the use of a remarkable "smart glove" that tracks hand and finger movements during rehabilitation exercises. The brainchild of UBC electrical and computer engineering professor Dr. Peyman Servati and his team at Texavie, a Vancouver startup, this innovative glove is set to redefine the landscape of stroke rehabilitation.
Dr. Janice Eng, a distinguished stroke rehabilitation specialist and UBC professor of medicine, will oversee the rehabilitation exercises where participants will don this state-of-the-art smart glove. The glove stands out due to its incorporation of highly sensitive sensor yarns and pressure sensors, seamlessly woven into a comfortable and stretchy fabric. This intricate network enables the glove to meticulously track, capture, and wirelessly transmit even the most delicate hand and finger movements.
Dr. Eng explains the significance of this advancement, stating, “With this glove, we can monitor patients’ hand and finger movements without the need for cameras. We can then analyze and fine-tune their exercise programs for the best possible results, even remotely.” The glove's ability to offer precise monitoring without the intrusion of cameras makes it a game-changer in stroke rehabilitation.
Dr. Servati sheds light on the technical prowess behind the smart glove, highlighting its unmatched accuracy in tracking hand and finger movement and grasping force. He emphasizes the role of machine learning models in achieving this level of precision. The glove's capability to determine angles of finger joints and wrist movement, coupled with its accuracy of at least 99%, rivals that of expensive motion-capture cameras.
What sets this smart glove apart in the market is not only its precision but also its wireless and comfortable design. An added convenience is its washable feature – a unique quality that allows users to clean the glove after removing the battery. Dr. Servati and his team have implemented advanced manufacturing methods, enabling the production of these smart gloves at a relatively low cost locally.
Looking beyond stroke rehabilitation, Dr. Servati envisions a broader scope for the smart glove. He foresees its seamless integration into the consumer market with ongoing improvements and collaboration with various industrial partners. The team also identifies potential applications in virtual reality, augmented reality, animation, and robotics.
The possibilities are vast and intriguing. Dr. Servati paints a vivid picture, saying, “Imagine being able to accurately capture hand movements and interactions with objects and have it automatically display on a screen. There are endless applications. You can type text without needing a physical keyboard, control a robot, or translate American Sign Language into written speech in real time, providing easier communication for individuals who are deaf or hard of hearing.”
As this innovative smart glove undergoes testing among stroke survivors, it not only signifies a breakthrough in stroke rehabilitation but also opens doors to a myriad of applications in the ever-expanding realm of wearable technology and human-machine interaction. The journey from stroke recovery to broader societal impacts showcases the potential of collaborative efforts in pushing the boundaries of technological innovation.
