视力丧失会对身体、社交和情感健康产生严重影响。盲童的教育带来了问题，因为许多学术学科（例如几何、数学）通常严重依赖视觉来教授。基于触摸的辅助技术是向盲人用户提供图形内容、提高学习可能性和社会包容性的潜在工具。凸起线图仍然是黄金标准，但刺激无法重新配置或调整，盲人不断需要帮助。尽管许多研究涉及技术发展，但很少有工作涉及教育和康复背景下可编程触觉图形的评估。在这里，我们在可编程触觉显示器上设计了旨在评估空间记忆技能和形状识别能力的测试。测试涉及一组盲人和一组低视力儿童和青少年，为期四个星期的纵向计划。在确定特定主题的难度级别后，我们观察到两组的跨课程表现均显着提高。学习效果与凸纸控制测试相当：然而，我们的设置需要最少的外部帮助。总的来说，我们的结果表明，可编程地图是在教育/康复环境中显示图形内容的有效方式。它们至少可以与传统纸质测试一样有效，同时提供卓越的灵活性和多功能性。
Vision loss has severe impacts on physical, social and emotionalwell-being. The education of blind children poses issues as many scholar disciplines (e.g., geometry, mathematics) are normally taught by heavily relying on vision. Touch-based assistive technologies are potential tools to provide graphical contents to blind users, improving learning possibilities and social inclusion. Raised-lines drawings are still the golden standard, but stimuli cannot be reconfigured or adapted and the blind person constantly requires assistance. Although much research concerns technological development, little work concerned the assessment of programmable tactile graphics, in educative and rehabilitative contexts. Here we designed, on programmable tactile displays, tests aimed at assessing spatial memory skills and shapes recognition abilities. Tests involved a group of blind and a group of low vision children and adolescents in a four-week longitudinal schedule. After establishing subject-specific difficulty levels, we observed a significant enhancement of performance across sessions and for both groups. Learning effects were comparable to raised paper control tests: however, our setup required minimal external assistance. Overall, our results demonstrate that programmable maps are an effective way to display graphical contents in educative/ rehabilitativecontexts. They can be at least as effective as traditional paper tests yet providing superior flexibility and versatility.
