[Tactile technology for pain evaluation in blind people]

Area of Science:

• Pain perception research
• Sensory evaluation studies
• Human-computer interaction

Context:

• Assessing pain intensity in visually impaired populations presents unique challenges.
• Existing pain scales may not effectively cater to tactile sensory experiences.
• The Ceará Blind People Association provided valuable participant input.

Purpose:

• To explore blind individuals' perceptions of a novel 'Tactile Scale' prototype for pain evaluation.
• To understand how tactile sensory attributes influence pain intensity assessment.
• To identify cultural meanings and practical applications of the scale within the blind community.

Summary:

• A descriptive study utilized semi-structured interviews with blind individuals to gather feedback on the Tactile Scale prototype.
• Key themes included pain perception at fingertips, the role of texture, shape, and size in tactile scale evaluation, and prototype refinement.
• Participants' tactile sensory experiences offered new insights for pain research and improved the scale's communication effectiveness.

Impact:

• Blind people's tactile perception can inform the development of more inclusive pain assessment tools.
• The study highlights the potential for sensory-based tools to enhance pain communication for visually impaired individuals.
• Findings can guide future iterations of the Tactile Scale for improved user satisfaction and clinical utility.
