The effect of sensory-specific guides on the virtual training of individuals with intellectual disabilities was investigated. A virtual vocational training system was developed to provide selective sensory guides, and participants were categorized into visual or auditory groups by identifying the sensory type of cues they utilized effectively. Video models and visible objects were employed as virtual interventions. Participants who received video model interventions showed a statistically significant improvement in task performance than the other group (Kruskal-Wallis H = 7.48, p = 0.006). The visual attention group that utilized video models improved by 46.72%, while the auditory attention group that used visible objects showed a lower improvement of 23.38% (Kruskal-Wallis H = 2.92, p = 0.026). Correlation analysis of virtual intervention utilization patterns revealed that these virtual interventions were beneficial for individuals with strong visual attention. Therefore, virtual interventions and teaching methods should be tailored to the sensory characteristics of individuals.
