[0011]

By the way, the display device 1
Since the display image of the display target terminal device 71 is enlarged and displayed as it is on the screen 3, the pointer 61a 'displayed on the screen 3 and the pointer 74a' displayed on the display target terminal device 71a ' Although the dimensions were different, the shapes, colors, patterns, etc. were the same. Similarly, the pointer 61b 'and the pointer 74b' or the pointer 61c 'and the pointer 74c' have different dimensions but the same shape, color, and pattern.

For example, when using a computer for each of the display target terminal devices 71, the same model may be used for all the computers, or different models may be used for each. When the same model is used for each display target terminal device 71, for example,
When a PC having the same OS is used for all of the display target terminal devices 71, as shown in FIG. 6, the pointers 74 displayed on the display target terminal device 71 usually have the same shape as each other.
The colors and patterns are the same. Therefore, as described above,
The shape and color of the pointer 61 displayed on the display device 1
The patterns are the same as each other.

There was a problem that it was difficult to perform. Specifically, for example, when the screen windows 31 displayed on the screen 3 are images similar to each other, the identification between the screen windows 31 is determined by the shape, color, and pattern of the pointer 61 displayed on the screen window 31. It depends heavily on such things. Therefore, the pointer 6
If the shapes, colors, patterns, etc. of the screen windows 1 are the same, it is difficult to identify each screen window 31. As a result, when performing work while checking a plurality of screen windows 31 alone,
, It is difficult to understand whether the user is operating the display target terminal device 71 corresponding to, and it becomes difficult to perform the task.

On the other hand, when different models are used for the respective display target terminal devices 71, for example, when different OSs are used for all of the display target terminal devices 71, the display is performed on the display target terminal devices 71. Pointer 74
Usually have different shapes from each other. If the shapes of the pointers 74 are different from each other, as described above, the screen 3 of the display unit 2
Are different from each other. When one operator operates a plurality of display target terminal devices 71 while watching the screen 3, the pointer 61 on the screen 3
Are different from each other, it is difficult to operate the pointer 61 on the screen 3. Specifically, when the position of the pointer 61 is specified for the object displayed on the screen 3 while looking at the screen 3, if the shape of each pointer 61 is different, the position for specifying the position It is different for each 61, and it is difficult for the operator to operate the pointer 61.
