Abstract: PURPOSE: A 3D human body model generating system and method thereof are provided to generate a human body model by using a deducted parameter according to an analysis based on a real human body model obtained through 3D scanning. CONSTITUTION: A pose changing device(300) extracts the location coordinates of human body parts including the shoulder, elbow, and knee based on the location coordinates of a plurality of feature points included in a 3D body model. The pose changing device generates a 3D human body skeleton model by connecting the location coordinates of the extracted human body parts. A human body modeling device(400) partitions the 3D human body skeleton model into a human body unit which has a meaning such as an arm, a leg, or a body. The human body modeling device generates a dynamic human body model by allocating a human body joint location coordinate corresponding to a vertex which is distinguished according a previously set divided plane.

Abstract: PURPOSE: A handsfree bicycle is provided to carry out steering by changing the centroid of a rider and braking by reversely rotating the pedals without manipulation by hands. CONSTITUTION: A handsfree bicycle comprises a front body part, a driving part, a rear body part, and a connection part. The front body part includes pedals(107) and a front wheel(103) which are fixed to the front upper and lower parts of a front frame(101), respectively. The driving part connects a chain(106) connected to the pedals to the front wheel with a gear and transfers power. The rear body part has a rear wheel(104) fixed to both sides of a rear frame(102). The upper part of the rear wheel inclines toward the center of the bicycle. The connection part connects the front body part, the rear body part, and a rotation connector with a suspension.
