document: Using virtual reality to teach disability awareness A desktop virtual reality -LRB- VR -RRB- program was designed and evaluated to teach children about the accessibility and attitudinal barriers encountered by their peers with mobility impairments . Within this software , children sitting in a virtual wheelchair experience obstacles such as stairs , narrow doors , objects too high to reach , and attitudinal barriers such as inappropriate comments . Using a collaborative research methodology , 15 youth with mobility impairments assisted in developing and beta-testing the software . The effectiveness of the program was then evaluated with 60 children in Grades 4-6 using a controlled pretest/posttest design . The results indicated that the program was effective for increasing children 's knowledge of accessibility barriers . Attitudes , grade level , familiarity with individuals with a disability , and gender were also investigated
