Abstract

A method for preventing Computer Induced Repetitive Stress Injuries (CRSI) that records operation statistics of the computer and calculates computer user'"'"'s weighted fatigue level; and will automatically remind user of necessary guiders when the fatigue level reaches predetermined threshold, therefore CRSI is effectively prevented.

Claims

1. A method for preventing Computer Induced Repetitive Stress Injuries (CRSI) that records operation statistics of a computer and calculates computer user'"'"'s weighted fatigue level and automatically reminds user of necessary guiders to effectively prevent CRSI, comprising:

(a) starting the program and reading a plurality of predetermined settings;

(b) picking PC operation statistics within each unit time (t) and calculating weighted unit fatigue level (X) and then accumulating an effective fatigue level (Ym);

(c) starting corresponding guider when the effective fatigue level reaches predetermined threshold; and

(d) restarting said effective fatigue level (Ym) and re-calculating after said guider is finished.

2. The method for preventing CRSI of claim 1, wherein said effective fatigue level (Ym) accumulated from startup till the m-th unit time (t) is calculated with following formula:

Ym=X₁²+ . . . +X_m-1²+X_m²−

n*Z, in which;

m;

Accumulated Time;

n;

Fatigue Reduction Times when X=0;

X;

Fatigue Level within unit time (t);

Y;

Effective fatigue level; and

Z;

Predetermined Unit Fatigue Reduction Value when X=0.

3. The method for preventing CRSI of claim 2, wherein said unit fatigue level (X) within unit time (t) is calculated with following formula:

X=a*A+b*B+c*C+d*D;

in which;

a, b, c, d;

Predetermined Weighted index;

A;

Keystrokes;

B;

Clicking of the Mouse;

C;

Mouse Scroll; and

D;

Page Up and Down.

4. The method for preventing CRSI of claim 1, wherein said operation statistics comprise of at least keystrokes, clicking of the mouse, mouse scroll, page up and down, etc.

5. The method for preventing CRSI of claim 1, wherein said step (b) further comprises:

calculating a unit time (t);

picking operation statistics and classify operations in different types;

accumulating times of each operation type;

when the time reaches said unit time (t), calculating a weighted unit fatigue level (X); and

accumulating said unit fatigue level (X) to said effective fatigue level (Y_m).

6. The method for preventing CRSI of claim 1, wherein said step (c) further comprises a threshold of said effective fatigue level;

and the program will start the corresponding guider when said effective fatigue level (Ym) reaches said predetermined threshold.

7. The method for preventing CRSI of claim 1, wherein said step (c) further comprises a threshold of said effective fatigue level and a trend of operation level (Ym-Ym-1);

and the program will start the corresponding guider when said effective fatigue level (Ym) reaches said predetermined threshold and said trend of operation level (Ym-Ym-1) is a negative value.

8. The method for preventing CRSI of claim 1, wherein said step (c) further comprises a threshold of said effective fatigue level, a trend of operation level (Ym-Ym-1) and a count down user reminder;

and when said effective fatigue level (Ym) reaches said predetermined threshold and said trend of operation level (Ym-Ym-1) is negative, the program will start the corresponding guider after user confirms on the reminder.

9. The method for preventing CRSI of claim 8, wherein said step (c) further comprises:

when user does not confirm on the reminder, the program will delay the reminder for predetermined period of time and then come back.

10. The method for preventing CRSI of claim 1, wherein said step (c) further comprises a plurality of threshold values of said fatigue level corresponding to different guiders respectively.

11. The method for preventing CRSI of claim 1, wherein said guider comprises of at least an eyeball exercise and an eye blinking reminder with different threshold values of said fatigue level.

12. The method for preventing CRSI of claim 1, wherein said guider further comprises of a user-define media file for playback on screen.

13. The method for preventing CRSI of claim 12, wherein said file can be designed in form of at least text, picture and audiovisual information.

14. The method for preventing CRSI of claim 1, wherein said guider further comprises of a transparent color screen masks that gently cuts in desktop on screen.
