Abstract
Line length perceptual characteristics have been studied from various viewpoints: for example, the person's initiative in the movements, and the sensations such as the proprioceptive sensations that return the physical states of joint rotations, the muscle activity sensations with extension and flexion, and the cutaneous sensations. However, in the existing works, there have been limited within specific aspects. Therefore, from the viewpoints of covering the above-described factors generally, two-dimensional line segment perceptual characteristics were examined by using a 2-D Cartesian coordinate liner actuator. The Line length perceptual characteristics shall be applied to line drawing presentation systems for visually impaired persons in the future.
