Abstract: A method for measuring motion postures of lower limbs of an automobile collision dummy continuously collects lower limb images of the automobile collision dummy during a collision in a real automobile collision test; identifies an edge contour in each lower limb image; samples a plurality of points from the edge contours for fitting to obtain a lateral thigh expression, a lower medial thigh expression, a lateral lower leg expression, and a lower medial leg expression respectively; determines various bone positions, various joint positions, and various bone angles of each lower limb; and associates the various bone positions, the various joint positions, and an included angle between two ends of each joint in the plurality of lower limb images in a chronological order to form a series of two-dimensional human rod-shaped model diagrams.

Abstract: A tactile sensation providing method and device. The tactile sensation providing method includes: generating a first tactile sensation based on information of a contour attribute of a visual object; generating a second tactile sensation based on information of a texture attribute of the visual object; and generating a third tactile sensation based on information of a roughness attribute of the visual object.
