Electronic display devices such as iPad and Kindle have recently attracted considerable attention as, reading media. Although the display performance and, business model concerning the contents have been discussed, there has been little discussion on comfortability, and - kansei like readability. In this paper, we conducted task performance investigation and impression evaluation among electrophoretic displays, liquid crystal displays and paper in order to examine readability for electronic displays, especially electrophoretic displays. In the task performance investigation, the reading speed, error detection rate and comprehension were measured. In the impression evaluation, the impression of the display, reading media and sense of fatigue were examined. As a result of task investigation, it was shown that the electrophoretic display was more comprehensible than that of the liquid crystal display. In the impression evaluation, the following results were obtained; 1) Although the display properties for the electrophoretic display almost passed muster, there was room for improvement in the beauty of the display. 2) The electrophoretic display was easier to read and concentrate on than the liquid crystal display. 3) The electrophoretic display was less likely to cause eyestrain and stiff-neck than other media. Principal component analysis revealed that the synthetic readability for the electrophoretic display was superior to the liquid crystal display, and moreover, the novelty of the electrophoretic display was superior to that of the other media.

In this paper, we discussed the particle based mechanical model for numerical simulation of clothing pressure. Human body and clothing were represented as an elastic body by particle system, collision between human body and clothing was represented by impulse force based model. The two simulations were conducted to evaluate the validity of the suggested model. In the first simulation, clothing pressure on the elastic cylinder covered with cloth was predicted to evaluate the precision of static clothing pressure prediction. As a result, it was confirmed that it had the accuracy of 0.08 kPa, but there was a room for improvement to predict on the edge of cloth. Although it is considered that the mesh resolution (particle distance) caused the problem, it is important to decide a suitable mesh resolution for purpose because it is directly with calculation time. In the second simulation, we conducted the simulation that winding elbow with sleeve to evaluate the precision of dynamic clothing pressure prediction. As a result, it was observed that clothing pressure changed with elbow flexion. However it was not able to obtain the accurate result caused by numerical instability in the case of fast elbow flexion. It is considered that time step and collision model between clothing and human body on the simulation caused numerical instability. Improvement and implementation of the simulation considering whole body motion for dynamic clothing pressure prediction are our future work.
