For the visually impaired, navigating a fresh environment usually takes repeat practice to comprehend the layout, so to reduce safety issues, new virtual reality technology is now able to provide a safer, more flexible practice environment.

To help them, assistant professor of gaming Rongkai Guo is  to create innovative and immersive simulation training.

鈥淚magine being able to use virtual reality to instantly map a room with technology sensors that could warn individuals about where furniture is positioned,鈥� said Guo.

The virtual reality exercises developed by Guo and his team of researchers in Kennesaw State鈥檚 College of Computing and Software Engineering will expand sensory experiences and build strong mental representations to help the visually impaired in coping with daily challenges.

The team鈥檚 high-tech virtual reality research stretches into the area called Head-Related Transfer Function (HRTF), which is how the ear receives sound from a point in space. Using two earphones, the HRTF becomes prominent in sensing sound differentiation at a position in virtual environments.

鈥淭he VR programs we鈥檝e developed provide relevant spatial audio feedback, and this 3D audio technique, using HRTF, will help the visually impaired better use their auditory senses,鈥� said Guo, who works with graduate research assistant Maio Dong and undergraduate research student Jerome Lester. One of their training games mimics a ball bouncing around a room, encouraging the user to follow the toy鈥檚 movement using only sound clues.

For the past year, Guo has been working with the  in Atlanta to understand the needs of those with visual disabilities. He analyzes behavior and movement to create real-world adaptations in virtual reality.

鈥淭his research is an opportunity to use innovation and new technologies to try to solve some of the challenges for adults who are newly blind and visually impaired,鈥� said Anisio Correia, vice president of programming at the Center for the Visually Impaired.  鈥淯sing virtual reality for vision rehabilitation is exciting, especially to see how the application of this training will enhance their mobility, and how it enables them to practice in a safe, yet realistic environment.鈥�

According to the Center, the majority of visually impaired lose their eyesight later in life as adults, due to illness or injury.

鈥淭he life skills they鈥檝e come to expect as normal now have to be relearned in a new way,鈥� Guo explained. These include crossing a street or making their way around a room.

Visually impaired individuals use guide dogs and white canes to assist them in managing life鈥檚 daily events by providing real-time, and nearly continuous, feedback. Guide dogs provide a reaction when something is not safe, and white canes provide instant audio feedback, depending on the environment of the cane鈥檚 tapping area.

鈥淲e developed our virtual reality technology to have a similar focus, which is providing continuous feedback,鈥� Guo said. 鈥淭he virtual reality practice helps individuals focus more using their auditory senses which helps them master certain skills before encountering those daily experiences in real situations.鈥�

鈥淭hey can practice at home and it gives them self-confidence,鈥� he added. Training for the visually impaired has traditionally included professional trainers, which can cost upwards of $100 per hour.

The 石榴直播 research team also reconstructed a 3D version of a busy intersection, simulating moving traffic, braking vehicles and audible crosswalk warnings.

Without delays in the technology鈥檚 feedback during the training, the researchers agree that virtual reality can bring more accurate representations of real-world scenarios to the visually impaired.  

According to Guo, a new wave of virtual reality products are hitting the market later this month, like Google鈥檚 Tango, which allows for the instant mapping of a room, and Microsoft鈥檚 HoloLens, which blends interactive 3D holographic content and the physical world.

Though expensive, these high-tech tools 鈥� with their highly immersive software 鈥� are the technological advancements that Guo said his research will lean on in the future to benefit this particular population.

Guo has researched virtual reality for people with multiple sclerosis for the past seven years, but embarked specifically on mobility development for the visually impaired with his 石榴直播 research team in 2015.  He hopes to develop potential applications to improve the daily life quality for people with visual impairments, including practice environments, training systems and educational games for children.
