We have been researching subjective evaluation experiments using Visual Analog Scale (VAS). VAS has the advantage of expressing subjectivity more intuitively. In this paper, we report an attempt of the subjective evaluation related to human lightness sense as fundamental research on what kind of color sense human has. We used VAS to obtain answers on where each gray image with different lightness corresponds to on the grayscale. Numeric values obtained by this evaluation experiment were analyzed to confirm the characteristics of the sensitivity of the individual. Moreover, at the same time, it was examined whether the VAS accurately reflected the subjective view of the person by the answer of what percentage of the grayscale was by the numeric value input. In order to conduct experiments smoothly, we developed an app that can perform VAS measurement and numeric value input simultaneously. We presented ten grayscale images to 13 subjects and obtained subjective measurements using this app. It was confirmed that when the lightness of the grayscale image is high, it can be recognized relatively accurately, but when the lightness is low, it tends to feel darker.

Smartphone was equipped with the function equal to a PC and has become an indispensable tool in the information society. In particular, many people are using it as entertainment tools such as video viewing, communication applications, and game applications while moving. There are many people using smartphone while walking on a platform or a street because they are enthusiastic about the application and cannot be interrupted. For this reason, many accidents have occurred due to the use smartphone while walking, and have been alerted not to use smartphone while walking. However, smartphone use while walking does not decrease at all. In this report, we examined the risk of using a smartphone while walking, based on changes in perception. In the experiment, we measured the effective visual field when standing without using a smartphone, standing with a smartphone, walking without using a smartphone, and walking with a smartphone. As the result, it was shown that the effective visual field was 45-56% narrower when using a smartphone than when not using a smartphone in both standing and walking. Thus, when using a smartphone, it is meant that it isn't possible to notice the changes in surrounding circumstances. Therefore, it was shown that using a smartphone while walking was dangerous.

The decline in students' reading comprehension is a hot topic. Noriko Arai has proposed a unique indicator called RST (Reading Skill Test) for evaluating text reading comprehension and has evaluated it in six fields. In addition, in beginner programming exercises, there are many students who are expected to be unable to do programming tasks because they cannot read the problem sentence. However, although it can be judged that programming problems cannot be made, the reason why programming is not possible has not been deeply pursued. Therefore, we propose reading comprehension indicators with reference to the indicators of RST, and classify students into multiple types based on the indicators. It is expected that the learning effect will be enhanced by preparing multiple question sentences according to the classified student type and letting students tackle the programming tasks that match them. It is costly to make several kinds of question sentences for the same task, but the learning effect is assumed to increase.

This study aimed to evaluate the effectiveness of an exercise on the people with autism spectrum disorder using the NeuCube spiking neural network (SNN) architecture. We collected EEG patterns during perception and imitation of facial expressions for each emotion. Comparing the collected data in perceiving and mimicking facial expressions, EEG patterns of typically developed person were very similar. This fact suggest that it seems that there are mirror neurons on facial expression in the human brain. Recently, some studies have been reported that mirror neuron system does not work well in the case of subjects with brain disorders. In this paper, we observed mirror neurons during normal perception and imitation of facial expressions in typically developed subjects (TP), ASD subjects who exercise regularly (ASDe), and ASD subjects who don't exercise regularly (ASDn). As a result of experiments, we confirmed the mirror neuron activities of ASDe subjects tend to be close to ones of TP subjects compared to ones of ASDn subjects. The results in the experiments imply the effects of regular exercise on autism spectrum disorder.
