Backgrounds: People with blindness (PB) are increasing in proportion to the increase in the number of patients with diabetes in the Asian region. They frequently fall from train platforms Purpose: To make the PB use the electric-stimulation alert device(energizer) in a simulated station platform environment and elucidate the ability to avoid collision with objects during walking. Subjects and method : PB were included as subjects of the study（n=10). Design: Double-blind randomized control trial. The endpoint was experimental success for each trial condition (success rate). Intervention: The subjects were set so that the driving condition of the device was unknown. Random shock and order of standby of the device and the combination were randomized. Intervention conditions were set to provide information when circuits from the sensor of the device were connected to the energizer on dropping the impact ball. Control condition was same as the intervention condition of the subject, but the circuit was not connected from the sensor of the device to the energizer at the time of dropping the impact ball, and no information was provided. (CTR-ID: UMIN000027880) Results: Eight participants were successful in setting up the equipment and environment during the experiment. The result was an 80% success rate, which was significantly higher when comparing device performance in control conditions. Eight among 10 trials were successful in the intervention condition, and 29 out of 46 were failed in the control condition. Limitation: This experiment is small number study, but the high number of trial times (frequency) makes the less c error item pooling value. Conclusion: This experiment was able to create an environment called simulated station platform and showed a significant success rate of avoiding object collision of 80% by using the device.
