Abstract
A cursor control system includes a cursor control device and a computer host. The cursor control device includes an operating plate, a blood vessel sensing unit, and a controlling unit. The operating plate is used for placing a palm and a finger of a user thereon. The blood vessel sensing unit is used for detecting the finger at different positions, thereby acquiring plural blood vessel images of the finger. According to the plural blood vessel images, a finger displacement amount is acquired by the controlling unit. In addition, a cursor moving signal corresponding to the finger displacement amount is transmitted from the controlling unit to the computer host. According to the cursor moving signal, the cursor is correspondingly moved.
Claims13
A cursor control device in communication with a computer host for controlling a cursor of said computer host, said cursor control device comprising:
- an operating plate for placing a palm and a first finger of a user thereon, wherein said first finger comprises plural first blood vessels;
- a first blood vessel sensing unit disposed on said operating plate for detecting said first finger at different positions, thereby acquiring plural blood vessel images of said first finger, wherein a first blood vessel image of said plural blood vessel images of said first finger is acquired by said first blood vessel sensing unit when said first finger at a first position is detected, wherein a second blood vessel image of said plural blood vessel images of said first finger is acquired by said first blood vessel sensing unit when said first finger at a second position is detected;
- and
- a controlling unit disposed within said operating plate and connected with said first blood vessel sensing unit, wherein said controlling unit acquires a first finger displacement amount of said first finger according to said first blood vessel image of said first finger and said second blood vessel image of said first finger, wherein a cursor moving signal is generated by said controlling unit according to said first finger displacement amount, and said cursor is moved by said computer host according to said cursor moving signal.
A cursor control system, comprising:
- a computer host with a cursor, wherein a database program is installed in said computer host, and a finger database is established within said computer host by executing said database program;
- and
- a cursor control device in communication with said computer host for controlling said cursor, wherein said cursor control device comprises:
- an operating plate for placing a palm and a first finger of a user thereon, wherein said first finger comprises plural first blood vessels;
- a first blood vessel sensing unit disposed on said operating plate for detecting said first finger at different positions, thereby acquiring plural blood vessel images of said first finger, wherein a first blood vessel image of said plural blood vessel images of said first finger is acquired by said first blood vessel sensing unit when said first finger at a first position is detected;
- and
- a controlling unit disposed within said operating plate and connected with said first blood vessel sensing unit and said computer host, wherein said controlling unit issues a cursor moving signal to said computer host according to said plural blood vessel images of said first finger, so that said cursor is moved by said computer host according to said cursor moving signal, or said controlling unit transmits said first blood vessel image of said first finger to said computer host, wherein after said first blood vessel image of said first finger is received by said computer host, said database program analyzes said first blood vessel image of said first finger to acquire a blood vessel message corresponding to said first blood vessel image, and said database program assigns a user code to said blood vessel message, wherein said user code and said blood vessel message are further stored in said finger database.
