People with visual impairments (VIPs) rely on hearing for orientation, but individual sensory preferences and environmental factors significantly influence their wayfinding strategies during orientation and mobility (O&M) training.
Area of Science:
- Human-Computer Interaction
- Assistive Technologies
- Sensory Perception
Background:
- Orientation and Mobility (O&M) training helps people with visual impairments (VIPs) navigate environments.
- Understanding VIPs' wayfinding preferences is crucial for effective O&M training.
- Current knowledge lacks clarity on factors shaping VIPs' wayfinding experiences.
Purpose of the Study:
- To map individual differences in sensory modality preferences for orientation and mobility in VIPs.
- To identify personal and environmental factors influencing these sensory preferences.
- To inform O&M training strategies based on individual needs.
Main Methods:
- Conducted interviews with eleven Dutch VIPs.
- Included participants with varying visual impairment onset, ontology, and severity.
- Employed thematic analysis to interpret interview data.
Main Results:
- Hearing is the primary sensory modality for orientation among VIPs.
- Reliance on other senses, knowledge, aid, or help varies individually.
- Environmental factors (weather, crowds, familiarity) impact sensory modality use.
- Energy management needs may mediate strategy and preference choices.
Conclusions:
- Findings offer insights for O&M instructors to tailor training strategies.
- Individualized approaches are essential for effective VIP wayfinding.
- Understanding sensory preferences enhances O&M training effectiveness.
