| Popis: | 95 This study developed a system that can actively remind the computer user to let his/her eyes take a break. This system uses a PC camera on top of the computer monitor to capture the image of the computer user and the environment. It applies Recognition technology of Eigenfaces to validate user’s status. In order to objectively estimate how long a person continuously uses the computer, the system can both determine whether the person uses the computer through face recognition technology and detect the signal of keyboard or mouse. At the same time, the system uses a built-in timer to record how long the user has worked on the computer, and another time is used to record how long the user has left. When the user is using computer, the system can not only detect the visual distance and eye’s blinking by the facial feature information, but also detect the illumination of your working area by color image transform. Furthermore, this system can detect the signal of keyboard and mouse by Win Hook. If the user doesn’t keep a proper visual distance from the monitor of computer, or his/her eyes blink too often or too less, or his/her has used the computer for a long time, or illumination is too bright or too dark according to background lighting behind the user, or the user uses computer within a improper time, the system will pop up a warning message via words/picture/voice to inform the user. Therefore, this developed system can initiatively be used to protect Computer user’s eyes from harm. |
