This study evaluated the feasibility of supporting independent indoor travel using reduced frequencies of auditory cues with two persons having total blindness and profound intellectual disability. For these persons, who had acquired satisfactory travel performance with cues occurring every 8 sec., the cue frequencies were reduced to one-half or one-third of the original level. Analysis showed that both participants could manage accurate travel under the new cue conditions, even though their travel time (efficiency) seemed negatively affected. Implications of the findings were discussed.
本研究评估了对两名全盲且有严重智力障碍的人使用减少频率的听觉提示来支持其在室内独立出行的可行性。对于这些在每8秒出现一次提示时已获得满意出行表现的人，提示频率降低至原来水平的二分之一或三分之一。分析表明，尽管他们的出行时间（效率）似乎受到了负面影响，但两名参与者在新的提示条件下都能进行准确的出行。讨论了研究结果的意义。
