The review reports, citing Hahn et al. (2019), a study of 22 BVIs comparing a Samsung multimodal tablet with tonal and vibration feedback against tactile representations of the same graphics; "there was no significant difference in the number of correct answers in either group." No effect size printed; equivalence was not tested.

"Hahn et al. (2019) used a Samsung multimodal tablet in combination with Google Classroom to ask 22 BVIs questions about graphics. Some students were provided with the tablet, which had tonal and vibration feedback, while others were given tactile representations of the same graphics. The authors found that there was no significant difference in the number of correct answers in either group."
