TWM488060U - Computer input device for muscular dystrophy patient - Google Patents

Claims (3)

A computer input device for use in a muscle atrophy patient, comprising: an identification mark coupled to a user's head; a camera continuously capturing an image of a user's face; a host electrically connected to the camera, the host receiving the The image captured by the camera, and the coordinate position of the identification mark in the image is determined according to the received image; and a screen is electrically connected to the host, and the host is based on the coordinate position of the identification mark in the image on the screen A corresponding position of a mouse cursor is displayed thereon; thereby, the movement and click state of the mouse cursor are controlled by the computer input device. The computer input device used by the muscle atrophy patient according to claim 1, wherein the camera sequentially captures the facial image of the user n times; the host captures the identification mark in each image of the camera, and sequentially identifies The center point coordinates (X1, Y1) to (Xn, Yn) of the different positions of the identification mark are viewed, and the host calculates the displacement amount of the center point coordinates of the previously obtained identification sticker and the coordinates of the center point of the identification sticker obtained afterwards. And when it is determined that the displacement amount is less than a set value, the host controls the mouse cursor on the screen to be in an unmovable waiting click state. The computer input device used by the muscle atrophy patient according to claim 2, wherein the host continuously recognizes the offset point of the center point coordinate of the identification sticker obtained last time and the coordinate point of the identification sticker obtained at the next time is n times small After the set value, the camera continues to capture the user's facial image for m times in sequence, and the host continues to capture the identification mark in each image of the camera, and sequentially identifies the center of the different positions of the identification mark. Point coordinates (X1, Y1) to (Xm, Ym), and calculate the coordinates of the center point of the previously obtained identification sticker in the Y-axis direction, and the coordinates of the center point of the identification sticker obtained in the next time are relative to the previous time in the Y-axis direction. When the coordinate position is up, the host controls the mouse cursor state on the screen to perform a click action.
