2 Vol.3 No.2(2015)pp.12- Introduction operation carried out under non-visual. We've been studying the minimum required Subjects and Methods amount of physical activity required to maintain the disabled elderly of vascular function up to now. The effect of the warning of physical inactivity showed effectiveness in their blood vessel hardness. In particular, they reported the effect of sleep at the time of the body movement as evidence of severe of prevention of elderly people with disabilities. Both the maintenance of low-intensity physical activity amount at the time of awakening and body movement time of sleep stage 2 was reported that help to maintain vascular function 1). However, the person who was blind from diabetes, there is a difficult problem. Maintenance of their waking time of low-intensity physical activity is a considerable difficulty. They need to make a conscious exercise in addition to the activities of daily living. When the blind to acquire a new movement, is often very appeal the slow operation and strong anxiety at the same time. They may be difficult to acquire low-intensity aerobic exercise. Therefore, the present study is simulated The subject is simulated visually impaired five subjects in which the eye mask (mean age 21 ± 2 years) Study design: experimental study Setting: Motion analysis laboratory in Institute Specific steps 1) A simulated visual impairment subjects the eye mask to stand on top of the square of one side 30 cm platform, by flexion-extension movement of the knee and hip joint at any speed, move the center of gravity so-called squat motion up and down to repeat five times an operation to. To instruct the "as soon as possible, to repeat the same operation". Once this session every week, it performed 8 weeks. On the basis of the Matsubara * 3 of the program, focusing on the object recognition loop in 3 bytes / pixel in the sequence RGB0 ~ 255 of the data in the non-compressed image data, when the information latent by adding a loop to skip from 1 to 8 pixels the making, make the variable at the time of information latency is the liver of the experimental. blind attempts to perception generation of the image of the whole body image using tactile information by the object recognition technology. Purpose The purpose of this study is to clarify the effect of suppressing the significant enhancement of the sense of insecurity and sympathetic function that occurs with the Figure 1 Artificial vison-tactile output system

3 Vol.3 No.2(2015)pp.12-2) leads to the object recognition technology out at IBMSPSSv21 (IBM, USA). measurement vary frequency measurement of RR wave the heart rate and the feeling of Results insecurity Visual Analog Scale in two conditions, a group of conditions that do not give a condition for giving the self-body image (VAS) by (LF / HF). Table1 operational stability duration of body position as a (result of motor learning): the first time as a baseline, at the start of the operation of the last time 8 weeks and operation stability All participants signed an informed consent form, and the study was conducted in after the end of five minutes, the mean and the variance value accordance with the Declaration of Helsinki. Main outcome measurements 1) Motion stability (performance of the motor learning): to measure the duration of body position in five of the operation, was the mean and variance value. Table2 VAS and LF / HF: the first time as a baseline, at the start of the operation of the last time 8 weeks, and after the end of 5 minutes Time leading to the lowermost point from the lowered starting point of the body position (re-elevation point) (Phase 1), the time that has continued the lowermost point (Phase 2), leading to the re-rise point and then re-raised from the lowermost point time (phase 3), the time that continues uppermost point (phase 4). Table3 2) A sense of insecurity Visual Analog Scale (VAS) and heart rate variability frequency measurement of the measured RR wave (LF / HF) Statistical analysis For the outcome between the two conditions group, the first time as a baseline, at the start of the operation of the last time 8 weeks and operation stability after the end of five minutes, the unpaired t-test for VAS and LF / HF was carried out. Statistical processing was carried Discussion Mirror image object recognition using a camera with a dedicated computer capable of object recognition (object recognition) of the tactile information of the spatial localization information experiment was successful. In

4 Vol.3 No.2(2015)pp.12- simulated visually impaired subjects who had an eye mask, the system gave a self-body image. Position on the support base surface of the subject, position on the sagittal plane, before issuing the position information on the par table, feeling of anxiety Visual Analog Scale, VAS, and heart rate variability frequency measured as the autonomic nervous system activity and (LF / HF) synchronization the data acquisition was made possible. Very interestingly, in simulated visually impaired, at the time of execution of the squat-like behavior of the tempo of 4Hz with the adjustment of speed, VAS suppression effect was observed. If the subject has given during the tactile information latency of localization of limit trunk leaning forward that does not fall from the base of support of 30 cm square during the operation carried out in the variable, and found that the VAS of relief occurs. We are on the basis of the Matsubara 2) of the program, focusing on the object recognition loop in 3 bytes / pixel in the sequence RGB0 ~ 255 of the data in the non-compressed image data, by adding a loop from 1 skip 8 pixels create a time of information latent, was sure to make a variable at the time of information latency is the liver of the experimental. Also convey the spatial orientation in the verbal instructions, reduction of sympathetic hyperactivity was not observed. This finding, using valid tactile latency information of dynamic localization by the mirror image object recognition to reduce that anxiety inhibition factor of the acquisition of low-intensity aerobic exercise for the blind to find the self-health (object recognition) It suggests the possibility of motor learning. As a previous study of the technical aspects, Shimada from the point of view of information security to help the visually impaired for knowledge acquisition, Shinohara, Shimizu, Shimojo et al., Many years there is a study of useful haptic devices 3), touch resolution effect of the map while being examined, the effect of the latency of the operation in the localization information is not considered. Required resolution of the case actually convey the localization information to motor learning support method to reduce the significant sense of insecurity due to the inexperience of the body operation in the blind tactile devices, from operating a long if pixels that do not involve walking 40 even at a resolution of 30 pixels, it was considered fully satisfies the conditions. When determining the time changes every moment to affect the sympathetic activity optimum information latent, it is possible to adjust the output time by changing the density of the object recognition loops can reveal this condition. This study, on the effects of scientifically still unknown human motor learning and anxiety, localization information under non-visual is intended to clarify the latency timing of information to work to sympathetic hyperactivity suppression, human speed It becomes breakthrough of mechanism elucidation of time to win a behavior that require adjustment. Very Interestingly, in simulated visually impaired, at the time of execution of the squat-like behavior of the tempo of 4Hz with

5 Vol.3 No.2(2015)pp.12- the adjustment of the speed, the effect of suppressing heart rate variability frequency (LF / HF) analysis on the significant sympathetic hyperactivity was observed case the admitted. This finding, to use a valid tactile latency information of dynamic localization by the mirror image object recognition to reduce that anxiety inhibition factor of the acquisition of low-intensity aerobic exercise (object recognition) for the blind to find the self-health on the continuation of the movement in the image of the whole body image can be expected. Conclusion As a way to reduce the "sense of insecurity and that occurs in association with the performance non-visual under operating significant enhancement of the sympathetic nerve function", mirror-image object recognition using a camera with a dedicated computer capable of object recognition (object recognition) space localization information successful in experimental tactile information and thereby obtain good results. In simulated visually impaired subjects who had an eye mask, the system gave a self-body image. Position on the support base surface of the subject, position on the sagittal plane, and before using the position information on face value, a sense of insecurity Visual Analog Scale, VAS of suppression is expected. Actually possible adaptation to the visually impaired has been shown.
