Research On The Evaluation Method Of Children's Sports Sensibility Based On Somatosensory Interaction

As one of the fundamental personal qualities, sports agility quality refers that the body can, under emergencies, change their motion and position quickly and accurately according to their physical, psychological or external requirements to adapt to the sudden external environmental changes. Agility quality is a comprehensive ability, which not only responses flexible degree of a person's brain, but also reflects the concord of individual action, the balance of the body, the observation power of the eyes, judgment and decision-making ability of the brain. Experts at home and abroad are generally believed that 7to 12-year-old is the key to develop the children's sports agility quality. So it is essential for the children of this age to measure accurately.Literature survey shows that the evaluative methods of sports agility quality at present mainly include the imaging measurement method, computer aided assessment and the method of biological signal feedback. But from the assessment object, the evaluation is suitable for athletes and college students and the children aged 7 to 12 apply to it rarely at present. From environmental assessment, the most of current belongs to the enclosed test, which can't satisfy the mutation of the key requirements of sensitivity, leading to the inaccuracy. It is difficult to play the real level of the children due to the simple and boring test contents, and depressive test environment. To solve these problems arising from the evaluation method, the paper is based on the body and feeling interaction technology of computer aided assessment, using Unity3d to create virtual situation and Kinect to realize the interaction of computer and testee. The assesment items including certain tasks would be designed by assesment indexes and then the motion sensitive quality of the tested children would be evaluated through their performance. Through experimental analysis and verification of the assesment items, the feasibility and applicability of the assesment system can get tested. The results showed that the assesment system of children's motion sensitive quality based on somatosensory interaction was suitful for the test of children's motion sensitive quality because of its good reliability and validity. This study conbined the somatosensory technology with traditional computer-aided assesment, which enhanced the sense of immersion and operation during the evaluation, improving the assesment results, enriching the assesment methods and also providing a new way of thinking to put somatosensory technology into educational applications.
