摘要： In an electrical stimulation device and an electrical stimulation method thereof, electrical stimulation can be adjusted more in real time, and stability and safety of the electrical stimulation can be more improved. An electrical stimulation device includes an electrode an electrical signal supply section, a skin impedance detection section, and an electrical signal controller. The electrical signal supply section supplies an electrical signal for generating the electrical stimulation to the electrode. During the supply of the electrical signal, the electrical signal controller acquires information associated with skin impedance through the skin impedance detection section in a cycle shorter than a supply period of the electrical signal, and adjusts the electrical signal to be supplied to the electrode in the next cycle based on the acquired information associated with skin impedance.

摘要： The invention relates to a technique for reducing computation time for force vector calculation. A force vector reconstruction method that uses an optical tactile sensor, comprises a step for obtaining a marker image by taking an image of behavior of colored markers when an object contacts a contact surface of an elastic body, a step of obtaining information relating to the marker behavior from the marker image, the information being more than the number of force vectors to be obtained, and a step of obtaining force vectors as outputs by inputting information relating to the obtained marker behavior to a transfer function. The step of obtaining force vectors comprises calculating force vectors using only information relating to behavior of markers neighboring region A1 of a position A where it is desired to obtain force vectors.

摘要： In a touch sensor, one ends of optical fibers are disposed at positions corresponding to respective pressure sensing points on a sensor sheet. The optical fibers in a bundled form are connected in a detection unit. The detection unit includes therein a camera that takes an image showing a change in luminance at the other ends of the optical fibers. A transmissive body is disposed to contain the other ends of the optical fibers and light sources. Upper and side faces of the transmissive body are covered with antireflection members. The transmissive body has substantially the same refractive index as the core of each optical fiber. A force applied to the sensor sheet is detected based on the change in luminance at the other ends of the optical fibers shown in the image taken by the camera.
