Visually impaired students face challenges in geography learning due to traditional visual teaching methods. This study explores the use of augmented olfactory feedback to enhance their learning outcomes. By introducing scents related to debris flow, an important topic for daily life and disaster prevention, this study aims to improve memory retention and engagement. Fourteen visually impaired junior and senior high school students with normal olfactory abilities participated. The experimental group received geography lessons enriched with scents, while the control group did not. Results indicated that while olfactory feedback did not significantly enhance geography learning or olfactory imagery, interviews revealed it could boost student interest, comprehension, and memory. Additionally, scent feedback may assist students in self-study environments like libraries. This research offers insights into the potential of olfactory feedback to improve learning for visually impaired students and suggests avenues for further exploration in other subjects.
