Method and system for sustained attention assessment

Abstract

The invention discloses a method and a system for continuous attention assessment. The method comprises the following steps: when a tested person is in a simulated task state, the behavior index data, the eye movement index data and the electroencephalogram index data of the tested person are acquired; the above acquired data are input into a preset comprehensive evaluation model, and the output of the comprehensive evaluation model is adopted as one of a plurality of assessment grades. The comprehensive evaluation model is obtained in advance through the following mode: an ideal evaluation index table of the plurality of assessment grades is obtained based on the test data of tested people of a preset number in the actual task state, and a multi-input and single-output relation model is obtained through the neural network learning process under the supervision of the ideal evaluation index table. According to the invention, the continuous attention is fully fused with specific scene task characteristics, and indexes of three dimensions are adopted. A more objective and more accurate continuous attention assessment scheme is established from the representation layer to the mechanism layer, and from exogenous factors to endogenous factors.

Description

technical field [0001] The invention relates to the technical field of attention training and control, in particular to a method and system for continuous attention assessment. Background technique [0002] Special occupations with very high attention requirements, such as pilots, racing drivers, airport tower air traffic controllers, high-speed rail traffic dispatchers and other special professionals need to have a high degree of continuous attention control ability to ensure the execution control of key tasks and The precision of time. Obviously, improving the continuity or focus of attention also helps to improve the work efficiency of non-specific professionals. For example, it is also of great benefit to the training of ordinary adults or human resource departments of enterprises and institutions. [0003] In the existing attention training schemes, its applicable objects are usually aimed at specific groups of people. For example, the patent documents with publication...

Problems solved by technology

Therefore, if the continuous attention index of the high-speed train dispatcher cannot meet the predetermined needs, it will affect the punctuality rate of the train, the efficiency of the shunting operation, and even the safety of the train in the event of an emergency.

In the prior art, the training or assessment of its sustained attention usually draws on existing schemes, that is, to use sustained attention to identify the state of drivers and other personnel, mainly for the selection of indicators in a relatively static state of brain activity , Difficult, this kind of scheme considers a single factor, the granularity of training or assessment results is too coarse, it is difficult to control the accuracy, and it is difficult to avoid the influence of some individual or subjective factors, which can easily lead to continuous attention levels that do not meet the standard Workers stay at work for a long time without being discovered, which affects driving efficiency or poses safety hazards
