If it is inequality that the tester judges the first stimulation sites signal and the second stimulation sites signal, then by the "No" button;
(h) the feedback signal acquisition module is gathered the feedback signal that "Yes" button or "No" button are produced, and obtains tester's response time and carry out to judge according to described feedback signal:
If it is in full accord with the numbering in each vision that produces the second stimulation sites signal and haptic signal source 1 to produce the numbering in each vision of the first stimulation sites signal and haptic signal source 1, and the tester then represents tester's correct judgment by the "Yes" button in step (g);
If it is in full accord with the numbering in each vision that produces the second stimulation sites signal and haptic signal source 1 to produce the numbering in each vision of the first stimulation sites signal and haptic signal source 1, and the tester then represents tester's misjudge by the "No" button in step (g);
If it is not quite identical with the numbering in each vision that produces the second stimulation sites signal and haptic signal source 1 to produce the numbering in each vision of the first stimulation sites signal and haptic signal source 1, and the tester then represents tester's misjudge by the "Yes" button in step (g);
If it is not quite identical with the numbering in each vision that produces the second stimulation sites signal and haptic signal source 1 to produce the numbering in each vision of the first stimulation sites signal and haptic signal source 1, and the tester then represents tester's correct judgment by the "No" button in step (g);
(i) the feedback signal acquisition module sends to data processing module with the resulting tester's of step (h) response time and judged result by the feedback signal sending module, finishes one time test loop this moment;
(j) data processing module accumulative total test loop number of times if the test loop number of times sets value less than total number measured, then returns execution in step (c) and carries out test loop next time; If the test loop number of times equals described total number measured setting value, then execution in step (k) is not restarted test loop;
(k) data processing module carries out statistical disposition to tester's response time and judged result, and the statistical disposition result is preserved.Data processing module calculates the average and the variance in response time that the tester makes the circulation correspondence of correct judgement, and the correct cycle-index of judging accounts for the percentage ratio (accuracy) of total number measured, and these statistical results and initial data are presented in the tabulation mode.
As preferred embodiment of the present utility model, at first carry out six parameter settings in PC: total number measured is set at 60 test loop (60 trail); Stimulus type is set at single tactual stimulation; Stimulate quantity to be made as and cause 3 of tactual stimulationes in 8 signal sources at random; Stimulus intensity is made as 200hz; Presentative time is set at 500ms; Be set at 800ms blanking time.After six parameter settings finished, stimulus signal produced at random, made each test (trail) be presented on stimulation sites randomization in 60 circulations on tester surface---promptly in 8 positions, present 3 tactile vibrations sources wherein at random; And in 60 tests that require to present, the situation that whether identical the first stimulation sites signal is with the second stimulation sites signal respectively accounts for half, if twice signal is inequality, represents that then it is inconsistent having and only have one in three positions.As the first stimulation sites signal among Fig. 3 is 235, promptly be numbered 2,3,5 position for stimulating position of appearing, and the second stimulation sites signal is 236.Each test is made up of three phases, comprise that as Fig. 3 the first stimulation sites signal presents stage A, the interval presents Phase I SI and the second stimulation sites signal presents stage A ', the presentative time of stage A is 800ms for the blanking time of 500ms, Phase I SI, stage A ' presentative time identical with stage A, be present stage or present at the second stimulation sites signal and finish in the t millisecond (t can adjust voluntarily), the tester need judge whether the tactual stimulation position that presents for twice is in full accord.If be judged as the "Yes" button that " unanimity " then presses the right hand; If be judged as the "No" button that " inconsistent " then presses left hand.After the tester pressed the button, tester write down tester's response time automatically and judges whether correctly, simultaneously these two feedback signals is sent to and presents in the upper PC and preserve.At this moment, a test loop finishes.If the tester does not make the button reaction in the t millisecond time, then this test loop also stops automatically, and system default is a misjudge.
After a last test loop finished, 1s next one test just beginning circulation presented at interval.After each test loop finishes, the corresponding raw data results of computer recording.60 test loop finish, and tester stops test automatically, and show corresponding initial data with form in upper PC, and calculate accuracy, the meansigma methods in response time and the variance yields of 60 tests automatically.Data result presents in the mode of tabulation, and the preservation of forms such as support Microsoft Excel, text text, spss form is preserved in prompting.
According to the method for testing that this utility model provides, the testee of certain sample size is tested.The scope of sense of touch, visual sensitivity that draws all ages and classes colony through substantive test is as shown in table 1.
Table 1. test result
After utilizing this utility model to look the sense of touch tester to obtain more substantial test data, also can generate the mathematical model of subject variable, stimulation time, stimulus frequency and reaction performance, to use as testing standard by above-mentioned method of testing.
