Description
Technical field
The present invention relates to dynamic visual acuity testing field, and in particular to a kind of with hand eye coordination reaction time compensation function
Dynamic visual acuity method of testing.
Background technology
The visual resolving power of observer when dynamic visual acuity refers to have relative motion between object observing and observer.It is dynamic
Can the quality of state eyesight be closely related with complete the task under motion state.Therefore, dynamic visual acuity detection is checking each
Class human pilot, improves driver training effect and plays an important role.Relatively new survey in current dynamic visual acuity test system
Examination technology is that KVA dynamic visual acuities are tested, in Kva dynamic visual acuity test systems, the sighting target opening direction tool in sighting target generation system
Have " upper, upper right, the right side, bottom right, under, lower-left, a left side, upper left " this eight gears, eight gears occur according to random equiprobability mode.
In traditional kva dynamic visual testing signs generation system, click on after " startup " button, the sighting target generation system completed by computer produces one
Sighting target, sighting target size is gradually increased by 1.6 minimum grades, and general 1-2 seconds sighting target becomes 0.1 grade sighting target size.
The test system simulated target is close to testee from far near, and target becomes larger therewith, when testee identifies that sighting target is opened
After mouth direction, single pole is stirred, dynamic visual acuity test system provides corresponding eyesight testing according to single pole moment sighting target size is stirred
Grade.In conventional dynamic sighting target generation system, testee stirs single pole after identifying sighting target opening direction, with now sighting target chi
Very little size is used as eyesight basis for estimation.For kva dynamic visual acuity test system sighting targets change in size quickly, due to each testee
Reaction speed is different, if two people identify sighting target opening direction simultaneously, swift people's dynamic visual acuity test result is
If 0.7, the people's dynamic visual acuity test result for reacting slow may be exactly less than 0.6, and this is not that dynamic visual acuity test system is wanted
Result.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of with hand eye coordination reaction
The dynamic visual acuity method of testing of time bias function.
Technical scheme：
A kind of dynamic visual acuity method of testing with hand eye coordination reaction time compensation function, including step：
Step 1：KVA dynamic visual acuity tests are carried out to testee by KVA dynamic visual acuities test system, and record testee
KVA dynamic visual acuities level and sighting target run time；
Step 2：The initial dynamic visual testing sign of 0.5 grade is generated by KVA dynamic visual acuities test system and the generation time is recorded,
Testee stirs handle immediately after finding sighting target, and handle sends signal to computer by serial ports, and computer recording is received
The system time at serial ports moment simultaneously calculates the hand eye coordination reaction time；
Step 3：The hand eye coordination reaction time that the sighting target run time and step 2 obtained by step 1 is obtained calculates
The time used in target is identified to testee, so as to obtain the KVA dynamic visions after testee's rejecting hand eye coordination reaction time
Power level.
The KVA dynamic visual acuities test system carries out the test of KVA dynamic visual acuities to testee：
Dynamic visual acuity test system starts, and starts to generate the sighting target of 1.6 grades, when t1 represents the system of sighting target Startup time
Between；The t2 moment is that testee identifies sighting target opening direction, stirs handle, and handle single-chip microcomputer is sent to dynamic visual testing sign generation module
Serial communication order, dynamic visual testing sign generation module receives system time during serial communication；Calculated value s=t2-t1, the value is
Sighting target run time；Sighting target size is determined simultaneously.
Beneficial effect：The present invention is in order that dynamic visual acuity test system more objectivity, in dynamic visual acuity test system
Hand eye coordination test function is added, whole system externally exports two indices, and an index is that revised dynamic visual acuity is surveyed
Test result, another index is the hand eye coordination time.So that system one side dynamic visual acuity test more objectivity, the opposing party
The respond of face tester.
Brief description of the drawings
Fig. 1 is dynamic visual acuity test system structure figure.
Fig. 2 is conventional two crucial moments of dynamic visual acuity test system.
Fig. 3 is the dynamic visual acuity testing system software flow chart for rejecting hand eye coordination.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
The dynamic visual acuity test system of the present invention is by two module compositions, including KVA dynamic visual acuities test module and trick
Concerted reaction time test module, structured flowchart is as shown in Figure 1.In the operation interface of the dynamic visual acuity test system of the present invention
Provided with hand eye coordination testing button, the hand eye coordination reaction time for testing testee.
The t1 and t2, t1 existed in KVA dynamic visual acuity test modules in two material time nodes, such as Fig. 2 represents sighting target
The system time of Startup time, the moment dynamic visual acuity test system starts, and starts to generate the sighting target of 1.6 grades；The t2 moment is
Testee identifies sighting target opening direction, stirs handle, and handle single-chip microcomputer sends serial communication to dynamic visual testing sign generation module and ordered
Order, dynamic visual testing sign generation module receives system time during serial communication.Calculated value s=t2-t1, when the value is that sighting target is run
Between.Unique sighting target size is carved with during due in KVA dynamic visual testing sign generation systems each to correspond to therewith, when the moment, s was determined, sighting target
Size is accordingly obtained.
The hand eye coordination test module of the present invention is based on KVA dynamic visual acuity test modules, and concrete operating principle is as follows：
0.5 grade sighting target is immediately generated in interface click " hand eye coordination test " button, dynamic visual acuity test system to exist
Center Screen shows, now dynamic visual testing sign generation module logger computer present system time, and the time is accurate to millisecond, time note
For t3.Testee stirs handle immediately after finding sighting target, and handle sends signal to computer by serial ports, and computer recording connects
The system time at serial ports moment is received, the time is designated as t4.Then value u=t4-t3 is the hand eye coordination reaction time.
Dynamic visual acuity method of testing is as follows in the present invention：
Obtain generating to receiving handle serial communication this section from dynamic visual testing sign by KVA dynamic visual acuity test modules first
Run time s, then hand eye coordination reaction time u is obtained by hand eye coordination testing response time module, then testee identifies
Time used in target is w=s-u.Due to sighting target initial size, it is known that for 1.6 grade sighting targets, sighting target pace of change, it is known that so
The w moment is run in dynamic visual testing sign, sighting target size is uniquely determined.It can determine that testee eliminates according to the moment sighting target size
KVA dynamic visual acuity levels after the hand eye coordination reaction time.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
