Augmented Reality (AR) eyeglasses can help individuals with low vision better navigate their surroundings as the eye-wearable apparatus was able to boost function and mobility in patients that suffer from peripheral vision or viewing at low light, say investigators.
The group from Keck School of Medicine at the University of Southern California (USC) discovered that accommodated AR eyeglasses could enhance patients’ freedom by 50 percent and grasp functionality by 70 percent.
“With another strategy – using assistive technologies to improve, not replace, natural perceptions – our staff accommodated AR eyeglasses that job vivid colors onto patients’ retinas, corresponding to neighboring barriers,” Humayun educated.
Patients with retinitis pigmentosa wore accommodated AR eyeglasses since they navigated via a barrier test.
Utilizing video of every evaluation, researchers recorded the amount of occasions patients collided with challenges, in addition to the time required to finish the program.
The patients averaged 50 percent fewer collisions using the accommodated AR eyeglasses.
Patients also were asked to get a wooden peg from a black backdrop – situated behind four additional wooden pegs – without even touching the front products. They demonstrated that a 70 percent increase in grasp functionality with the AR eyeglasses.
Patients with retinitis pigmentosa have diminished peripheral vision and difficulty viewing in low light, making it tricky to recognize barriers and grasp items.
“They frequently need mobility aids to browse, particularly in dark surroundings,” Anastasios N. Angelopoulos, research project guide, said in a university statement.
he AR system overlays objects inside a six-foot wireframe using four vivid, different colors.
In doing this, the eyeglasses deliver visual color cues which assist individuals with constricted peripheral eyesight to interpret complicated environments, like avoiding obstacles in densely populated surroundings.
To achieve this, researchers used a procedure called simultaneous mapping and location, letting the AR eyeglasses to render the 3D arrangement of an area in real-time completely.
Based on Humayun, while significant technical and cost problems remain, this kind of assistive technology may finally become more functional for everyday use in the not too distant future.
