Heat Rate Variability (HRV) which is a physiological index has been investigated to evaluate the riding comfort of baby and parents who use strollers and wheelchairs, The HRV of the subjects who rode a wheelchair was measured through their electrocardiograms as well as the riding comfort. The subjects were six men whose ages were from 22 to 24 years old. The subjects and the wheelchair were traveled on the three kind roads to measure the HRV, the vibration of the subjects and the riding comfort. The items for evaluating the riding comfort consisted of the feeling of the vibration of each body part (head, chest, abdomen, upper-legs and lower-legs), the feeling, of stability, the feeling of getting tense, the feeling of stability, the feeling of tiredness and the synthetic riding comfort. As a result, it was confirmed that the vibration would increase the LF/HF if the wheelchair was moved on the interlocking road rather than on the general paved road with a significant difference. The relationships between the LF/HF and the riding comfort also suggested that the feeling of vibration at chest, the feelings of tiredness and stability would affect the LF/HF. Furthermore, at 3.2Hz, the correlation between the transmissibility from the wheelchair to around the subjects' chest and the LF/HF showed that there was a significant correlation. The result has showed that the riding comfort could be affected with the increment of the LF/HF which would be caused by the vibration of the subjects' body seating in the wheelchair from around 3 to 4Hz, and it has suggested that the LF/HF could be a physiological index which quantitatively describes the riding comfort. Finally, a stroller has been proposed according to the knowledge obtained through the above-mentioned experiments and the investigations into the existing strollers and wheelchairs.

为了评价婴儿车和轮椅上婴儿和父母乘坐舒适性的生理指标--心率变异性(HRV)，对坐轮椅的受试者的心率变异性进行了心电测量和乘坐舒适性的测定。受试者为6名男性，年龄从22岁到24岁不等。受试者和轮椅在三种不同的道路上行驶，测量受试者的心率变异性、受试者的振动和乘坐舒适性。评价乘车舒适性的项目包括身体各部位(头、胸、腹、大腿、小腿)的振动感、稳固感、紧张感、稳固感、疲劳感和综合乘车舒适感。结果证实，如果轮椅在联锁道路上移动，而不是在有显著差异的普通铺装道路上移动，振动会增加低频/高频。低频/高频与乘坐舒适性的关系也表明，胸部的振动感、疲劳感和稳固感会影响低频/高频。此外，在3.2赫兹，从轮椅到受试者胸部周围的传播率与低频/高频之间的相关性显示出显著的相关性。结果表明，受试者坐在轮椅上的身体在3~4赫兹左右的振动会引起低频/高频的增大，从而影响乘坐舒适性，提示低频/高频可以作为定量描述乘坐舒适性的生理指标。最后，根据上述实验和对现有婴儿车和轮椅的调查，提出了一种婴儿车。
