Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The system of the present invention is made up of computer, audio equipment and Kinect camera head. The user logs in by entering relevant personal information, enters each sub-item for evaluation, and finally submits the system to output the evaluation results. The flow chart of the whole evaluation system is as follows: figure 1 shown.

[0026] Each evaluation item of the present invention is all in certain situation, evaluates the attention level of the subject by the situation of task completion by the subject, so the following mainly from the design and realization of the test task, the design and realization of the test environment and the final test The analysis and evaluation of the results will introduce t...

Abstract

The invention discloses an attention scenario evaluation system based on Kinect interaction. The system comprises the implementation steps of (1) utilizing the multimedia analogue simulation technology for presenting a scenario similar to real life, introducing a lifelization interaction scenario into a test system, (2) utilizing a Kinect camera for conducting dynamic capture on a user, converting user information into a skeleton tracking system through image recognition, drawing a human skeleton which is placed into the scenario in the first step, (3) tracking motions of the user through changes of positions of articulation points of the human skeleton, adding event monitoring at the same time, constantly drawing new skeletons in the scenario, (4) achieving communication between hardware and designed scenario application programs through the AIR Kinect middleware, and (5) completing items in the Kinect interaction mode by the user, wherein the system evaluates the situation that the user completes the items by comparing the motions with standard motions. According to the attention scenario evaluation system based on the Kinect interaction, testing is completed in the Kinect interaction mode, attention of the detected user under the real-world situation can be reflected, and assistance by professionals is not required.

Description

technical field [0001] The invention relates to a system for assessing attention by adopting a situational method, in particular to a system based on Kinect somatosensory technology and using the most natural human-computer interaction method to realize attention assessment, which can be used for assessment of children's attention and for attention deficits. Provide supplementary medical treatment and evidence for diseases. Background technique [0002] Attention deficit hyperactivity disorder is a common disorder in children and adolescents. According to research, the incidence rate of this disease among school-age children in my country is as high as 5.83%. Due to factors such as environment and education, the incidence rate is increasing year by year. Therefore, timely measurement of children's attention to achieve early prevention has become an important issue. [0003] At present, the commonly used methods of attention measurement are paper-and-pencil task test metho...
