Computerized assessment of preference for severely handicapped individuals

Area of Science:

• Assistive Technology
• Rehabilitation Engineering
• Human-Computer Interaction

Background:

• Assessing preferences for individuals with severe handicaps is challenging due to communication barriers.
• Traditional methods may not capture the nuanced preferences of this population.
• Developing objective and systematic assessment tools is crucial for personalized interventions.

Observation:

• A computerized assessment procedure was developed using a computer program to interpret microswitch activations.
• The program generated three distinct sensory feedback events: visual, auditory, and tactile.
• A multiple baseline and multiple treatment design was employed across three subjects.

Findings:

• The computerized assessment effectively identified unique preference patterns for each of the three subjects.
• Data analysis revealed idiosyncratic preferences, highlighting individual differences.
• The system demonstrated reliability in capturing preference data.

Implications:

• This computerized approach offers a systematic and objective method for assessing preferences in individuals with severe handicaps.
• Findings suggest potential for improved personalized care and intervention strategies.
• The technology can be adapted for various applications requiring preference assessment in individuals with limited communication abilities.
