| Abstract | As computer based on-line education contents such as mathematics, languages, and sciences are being further developed, off-line based physical education contents need other type of skills or methods to be combined with on-line contents. One of the benefits of physical education system is that education contents can be shown and explained to all or to a group of students at the same time. Although this is a strong argument of the offline educational method, there is a lack to it. Taking the science hall as an example in which a number of various educational items such as chemical experiment, space and nature are displayed, it is very difficult or rather impossible to manipulate the object or change the experimental method of the exhibited items. From this point of view, input methods play an important role in operating contents. This paper suggests a new input method to control education programs displayed on large screens and located from a long distance. This non-touchable input method is implemented using general laser pointers with computer vision. Introduction From the early invention of computer, many scientists and engineers have developed various kinds of input and output devices to control the computer and its related devices. According to the development, people use several kind of devices (e.g. keyboard, mouse, trackball and joystick) when playing a game or studying on the Internet through the e-learning system. For example, the force feedback module of a racing game gives the vibration of a car to the gamer so that the player feels the car’s motion. Equally, chemical education books equipped with gripper and booklet can represent the molecule and manipulate it as if it would be manipulated in the real world. These devices are used not only to manipulate the desktop sized personal computer, but also to control the screen that is connected to the computer but cannot be found around the screen. [3][6][7][8][9][10][11][12][13]. Using a general input device in large screen based applications are not efficient to take the inputs from the many users. Put it another way, it is difficult to obtain the input data to manipulate a specific content from the user using e.g. a keyboard or a joystick. For instance, the virtual fishes of the aquarium at a science hall may usually provide touch screen monitors or switches as input devices which would enable us to control the systems. As we know that engineers and developers use them when some input data from the visitors are needed. Though we may control the system it would be impossible to control the system if the screen is placed at a long distance. In this respect, switches and touch screen monitors are not suitable as input devices, since screens are large and control computers are installed at different places in the science halls or museums. Moreover, monitors of touch screen are not larger than 21inches of size, |
