Problems solved by technology

However, in actual situations, objects seldom maintain a complete shape during movement. It may be due to its own shape change, or it may disappear due to occlusion, or it may move jointly with other objects.
The aforementioned test methods are mostly limited to a single form of simple multi-object tracking paradigm, and cannot completely and effectively obtain evaluation results for actual situations, lacking referenceability

Embodiment 1

[0056] Multiple markers are 8 gray balls, and target markers are any 4 of them. After the test subject presses the button, 8 small balls are displayed on the screen, and any 4 small balls are controlled to flash 3 times for a total of 1.2 seconds as the target mark. Then control 8 small balls to move randomly at a certain speed for 6 seconds. After the balls are at rest, the test subject identifies the 4 balls he thinks as confirmation marks, and presses the Enter key to confirm. The computer obtains the correct rate of the test object according to the target mark and the confirmation mark, and displays it on the screen.

Embodiment 2

[0058] Multiple markers are 8 gray balls, and target markers are any 4 of them. After the test subject presses the button, 8 small balls are displayed on the screen, and any 4 of them are controlled to flash 3 times for a total of 1.2s as the target mark. Then control 8 small balls to move randomly at a certain speed for 6 seconds, and control each of the 8 small balls to disappear randomly for 0.5 seconds during the movement. After the balls are at rest, the test subject identifies the 4 balls he thinks as confirmation marks, and presses the Enter key to confirm. The computer obtains the correct rate of the test object according to the target mark and the confirmation mark, and displays it on the screen.

Embodiment 3

[0060] Multiple markers are 8 gray balls, and target markers are any 4 of them. After the test subject presses the button, 8 small balls are displayed on the screen, and any 4 of them are controlled to flash 3 times for a total of 1.2s as the target mark. Then control 8 small balls to move randomly at a certain speed for 6 seconds, and control each of the 8 small balls to randomly turn into a ring twice for 0.5 seconds during the movement. After the balls are at rest, the test subject identifies the 4 balls he thinks as confirmation marks, and presses the Enter key to confirm. The computer obtains the correct rate of the test object according to the target mark and the confirmation mark, and displays it on the screen.

[0061] Embodiment three

[0062] The multiple marks are 4 straight lines, and the target mark is one end of the 4 straight lines. After the test subject presses the button, 4 straight lines are displayed on the screen, and a small ball is controlled to flash...

Abstract

The invention discloses an evaluation method and apparatus of multiple object tracking capability. The evaluation method of multiple object tracking capability includes the steps: receiving a test starting command which is generated from the key operation of a test object; according to the test starting command, displaying multiple marks on a screen, and selecting the target mark from the multiplemasks in a flashy mode; controlling the multiple masks to move for a first preset time period in the screen range; after the multiple marks become motionless, receiving a determination command whichincludes the determination mark identified by the test object from the multiple marks; and comparing the determination mark with the target mark to obtain the multiple object tracking capability evaluation result of the test object. The evaluation method and apparatus of multiple object tracking capability can effectively discriminate and screen the MOT (Multiple object tracking) capability of different individuals from the population, and can record the data sets of large samples, thus being convenient for knowing about the relative level of the test scores in the population.

Description

technical field [0001] The embodiments of the present invention relate to brain science technology, and in particular to a method and device for evaluating multi-object tracking ability. Background technique [0002] In daily life, multiple object tracking (Multiple object tracking, MOT for short) is a common activity, for example, a mother takes care of two children playing in a square. Sometimes as a professional, MOT ability is a necessary skill. For example, athletes on the basketball court need to keep an eye on multiple opponents at the same time; air combat personnel need to accurately monitor the trajectory of multiple enemy aircraft at the same time. The simple MOT task found that there are individual differences in MOT ability (Oksama and 2004). Moreover, MOT activities in real life are diverse, and there are obstacles of different degrees, such as occlusion and deformation of objects. [0003] Most of the current MOT test tasks are simple to simultaneously tra...
