Background technology
Nowadays, the pressure of students is increasing, especially middle college admission examination.It is inevitably applied with parent in workload
Pressure, student group study till all hours, mental very tired, the learning efficiency of such case Students ' also cannot be guaranteed.
Medical research also indicates that：Mental fatigue not only reduces study and work efficiency, and can psychologically cause psychological barrier
Hinder, psychological out of control or even mental crisis；Apathetic, absent-minded or even psychiatric disorder can be caused in spirit.According to statistics
District of Shanghai scientific research personnel's age at death in 1994 is 67 years old, dead 3.26 years old more early than the crowd that generally obtains employment, wherein 15.6% 35
The morning dead age bracket in year to 54.This illustrates that mental fatigue lower can equally endanger body accumulating over a long period to ignore for a long time.
Likewise, over fatigue will also result in driver group great harm, over fatigue can cause Drowsy drivers, i.e.,
This microsleep is made to only last for 2 to 3 seconds, is also enough to cause a miserable traffic accident for the vehicle of normally travel.There is research
Think that the 35% to 45% of traffic fatalities are attributable to driving fatigue.
So how to obtain a kind of quickly and effectively mental fatigue Tachistoscope device and method, to be increasingly becoming people gradual
A problem being increasingly concerned about.

Take tester absorbed degrees of data and loosen degrees of data, then successively with default first, second sets of threshold values of focus allowance
Cooperation is compared, so as to judge that tester is in normal condition, micro- fatigue state or severe fatigue state immediately.And pass through
Display module gives display feedback in real time.
Display feedback includes level of fatigue and shows that (for example, normal mode shows that micro- Fatigue pattern shows for amber light for green light
Show, severe Fatigue pattern is shown for red light), voice show that (for example, normal mode can report " normal ", " good ", micro- fatigue
Pattern can be reported " taking a good rest ", severe Fatigue pattern can continue report " taking a good rest "), alarm indication (for example, weight
Degree Fatigue pattern can be alarmed in the form of flicker alarm or alarm).In this way, tester either student or work
Author can very be visually known the degree of fatigue of itself at the first time, and tester is promoted to adjust oneself study in time
The rhythm of work helps tester that can initiatively alleviate mental fatigue in time, it is ensured that the study and work stabilised efficiency of oneself is effective.
