Abstract
A slide presentation system and a method of performing the same which are capable of providing a real-time interaction among conference presenter and attendees are disclosed. When a projector projects at least one slide to as map a screened image generated from a host, an image identifying unit identifies a pointer after an image capturing unit imaging the content expressed on the projected slide. After the pointer is identified, an orienting unit detects a two-dimension coordinate value with reference to where the pointer is pointed on the projected slide as the same as the screened image of the host. Then, the two-dimension coordinate values are transmitted to the host for determining an action of the pointer according to the two-dimension coordinate value with reference to the screened image of the host. By the present invention, the pointer pointing on the projected slide can be directly implemented as functioning a mouse.
