A Technology System to Help People With Multiple Disabilities Increase Contact With Objects and Control Environmental...

Area of Science:

• Assistive Technology
• Disability Studies
• Human-Computer Interaction

Background:

• Individuals with severe-to-profound intellectual disability and sensory-motor impairments often exhibit passivity and detachment.
• This detachment can limit their interaction with and engagement in their immediate environment.

Purpose of the Study:

• To evaluate a novel technology system designed to detect responses (e.g., hand contact) in individuals with severe intellectual disability.
• To assess the system's ability to deliver contingent environmental stimulation (e.g., music) based on detected responses.
• To determine if this technology can increase object interaction and environmental control for this population.

Main Methods:

• An ABACB design was employed with 8 adults with severe to profound intellectual disability and motor/visual impairments.
• The technology system, incorporating a webcam, provided contingent stimulation during intervention (B) phases and no stimulation during baseline (A) phases.
• A control (C) phase involved continuous stimulation, while sessions were limited to 5 minutes.

Main Results:

• Participant responses per session significantly increased from a mean of 3-6.5 during baseline to 10-18 during the first intervention phase.
• Responses declined during the second baseline and control phases, indicating the intervention's effect.
• A further increase in responses was observed during the second intervention phase, ranging from 13-19.5.

Conclusions:

• The assessed technology system demonstrates potential as an effective tool for increasing object interaction.
• The system may empower individuals with intellectual and sensory-motor disabilities by providing greater control over their environmental stimulation.
• This technology offers a promising avenue for enhancing engagement and reducing passivity in individuals with significant disabilities.
