Using an orientation system for indoor travel and activity with persons with multiple disabilities

Area of Science:

• Assistive technology research
• Rehabilitation engineering
• Disability studies

Background:

• Individuals with profound intellectual disability and blindness or severe visual impairment often face challenges with independent indoor mobility.
• Existing orientation and mobility (O&M) strategies may not fully address the complex needs of this population.
• Technological advancements offer potential solutions for enhancing independence in daily living activities.

Purpose of the Study:

• To evaluate the efficacy of a novel orientation system in facilitating independent indoor travel and activity.
• To assess the system's ability to support individuals with profound intellectual disability and blindness or severe visual impairment.
• To explore the potential of programmable control devices with acoustic and light cues for enhancing mobility.

Main Methods:

• A programmable control device linked to acoustic and light sources was developed.
• The system was tested on two participants with profound intellectual disability and blindness or severe visual impairment.
• An alternating treatment design (baseline vs. orientation phases) was employed to measure the system's impact.

Main Results:

• Both participants successfully reached designated destinations using the orientation system.
• Independent travel and activity completion improved significantly during the orientation phases.
• The system demonstrated effectiveness in guiding users through indoor environments.

Conclusions:

• The developed orientation system shows promise for promoting independent indoor travel and activity in individuals with multiple disabilities.
• This technology has significant implications for improving the quality of life for people with profound intellectual disability and visual impairment.
• The findings suggest potential applications for rehabilitation and care centers to enhance resident autonomy.
