摘要：
This investigation was an attempt to evaluate the effectiveness of an electronic obstacle-detecting (O/D) device for the blind. Ss [subjects] were 26 totally blind individuals. Three series of training sessions on the O/D were conducted. Performance was assessed in 1 pretraining session with the customary mode of travel a*d 3 posttraining sessions with the O/D. Ss were also given several psychological tests and 2 interviews. Using the O/D on a standard obstacle course, Ss took longer to walk than with customary aid, but errors were the same. Ss who walk unassisted made many fewer errors with the O/D than without it. For those Ss using a cane or a dog. the O/D was of little help. After more training on the use of the O/D, Ss reduced the time to walk the obstacle course while errors remained about the same. On the field tests Ss made fewer errors but took longer with the customary mode of travel than with the O/D. About 1/2 of Ss indicated a desire to own the instrument.
