[Synopsis]A simple and high-speed modulation technique using a white LED for illumination light communication are proposed to enable Ubiquitous Network. The proposed modulation technique enable a 110Mb/s operation. Experimental results show that the proposed system can play a key role in high-speed illumination light communication.

[Abstract] Mechanism of motion generation of human upper limb has puzzled scientists for a long time because of its high redundancy on mechanical structure and various factors from the environment. It was reported that illusion exerts a strong effect on the human upper limb motion based on the planning-control model of Glover hypothesis. In this study, we investigated the influence of Müller-Lyer visual illusion on the upper limb movement by changing the fingertip contact conditions.

This paper presents a method for measuring the spatial cognitive ability of the moving distance of the human hand by using motion capture (MoCap). To improve the measurement accuracy of MoCap, a method involving the use of an upper limb model is proposed in this paper. The proposed method has many advantages such as the use of a small number of markers,and better alternatives for marker sticking positions that can reduce inaccuracies due to small muscular deformation. To investigate the cognitive ability of the moving distance of a human hand, both horizontal and vertical hand movements are measured using the proposed protocol for six subjects. The results demonstrate that the average moving distances obtained in both directions become coloser to the standard length compared with the results obtained in the previous study. The experimental results also demonstrate a strong relationship between error of the hand moving distance and manipulability of the upper limb. Moreover, the maximum velocity observed during horizontal and vertical movements are compared; and the result implies that the gravitational force exerted on the arm evidently atlects the hand movement in the blindfolded state during vertical movement.
