Background technology
Recognition tests are the important means for carrying out personnel ability's characteristic research and selecting training.Spread out in laboratory research
Numerous recognition tests devices are born.Current recognition tests use computer technology in large quantities, and recognition tests software is with unification
The specific operation reaction unit such as set computer, keyboard, mouse or handle can complete various recognition tests, make general
Property preferable test platform, while record test data using computer software, can cause data record more accurately, data adopt
Collection also more enriches.But becoming the spy such as gravity environment because in environment, the general computer recognition test device in laboratory becomes
It is inapplicable.Because in these environment, not adding computer, mouse, keyboard, handle of special constraint etc. under the home of laboratory
The position of device can all be changed, and tested personnel body posture in itself is not also fixed, and cause test to be difficult normal development.
For example, in the change gravity environment that aircraft parabolic flight causes, tested personnel easily send out with respect to the attitude of computer screen
It is raw to change, cause tested personal observations' screen angle to fix, influence the observation to visual stimulus；Tested personnel are carried out
Operate the position of the devices such as mouse, keyboard, the handle of reaction also easily to change, cause tested personnel to be difficult normally to go out for drill
React.Becoming gravity environment can also produce some other testing requirements for being different from normal experimental situation.For example, normal real
Test in room environmental, recognition tests are typically configured by main examiner person, started, tested personnel are grasped according to the requirement of main examination
React, main examiner person can also exercise supervision and intervene when necessary to the test process for being tested personnel；And such as become weight
It is main to try often stablize to be configured by the side of, start and supervise in tester during the spy of force environment etc. is because of environment, and need
Independently carry out test by tester.Meanwhile, in zero gravity airplane etc. becomes gravity environment, in addition it is also necessary to automatically carry out gravity state
Identification and record, with distinguish the specific test result of tested personnel be under which kind of gravity condition carry out obtain.Te Yin
Specific demand under environment prevents existing recognition tests equipment from meeting testing requirement.

Remove, obtain ratio P (t), nearest 5 times detection P (t) values are averagely obtained into P per 0.5s1If, P1>=1.5, it is judged to " overweight ", if P1
≤ 0.5 is judged to " weightlessness ", if 0.5 ＜ P1＜ 1.5, is judged to " normal gravity "；
C, automatic presentation stimulate, suspend and data automatic recording
Changed in gravity：" normal gravity " is arrived " weightlessness ", or " weightlessness " is arrived " normal gravity ", or " normal gravity " is arrived
" overweight ", or " overweight " is arrived " normal gravity ", or " normal gravity " is arrived " overweight ", or " overweight " arrives 2s after " normal gravity ",
The notebook computer screen starts to present and stimulates, and it is anti-that tested personal observations by the handle do button on request after
Should, automatic pause when test lasts till that setting time or gravity state change so is one group of recognition tests；The cognition
Test software while automatic record test data, the corresponding gravity state of also automatic minute book group recognition tests；According to weight
Power condition change frequency, whole test bag contains multigroup recognition tests.
This test device can also can be suitably used for the cognitive survey of laboratory environment suitable for the recognition tests of change gravity environment
Examination, testee reduces influence of the attitude change to recognition tests result with respect to the attitude stability of computer screen in test.
This method of testing is fitted after comprehensive descision being carried out to current context information and subject's attitude information according to various kinds of sensors information
Preferably start, suspend stimulation and present and carry out data syn-chronization and record automatically, enhance spy because of the intelligence of recognition tests in environmental testing
Can property and independence.
