[0004]

However, except for the artificial adjustment of the amount of input / output information, that is, the information input / output between humans and humans, the input / output speed and form of the information are fixed, and even if multimedia is used. Since the information balance between the media is fixed, there is a possibility that uniform information input / output must be performed for different users.

[0005] Therefore, as the information to be handled increases, the man-machine interface through which the user inputs and outputs information becomes:
It could be a bottleneck to limit the effectiveness of the function.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to automatically set an input / output speed of media information and a media balance suitable for each user, thereby making the connection state of the man-machine interface dense, and making the user close. Another object of the present invention is to provide an information input / output device capable of realizing a large amount of information input / output per unit time without increasing the load on the device.

[0008]

The information input / output state of the output means and the input means is monitored by the information monitoring means, and the input / output state of the information of the output means and the input means or the media balance is adjusted by the adjusting means according to the monitoring result. To adjust.

As described above, the information input / output state between the user and the apparatus is monitored, and if the result of the monitoring satisfies any of the preset conditions, the information input / output state can be adjusted. Since there is an information input / output state adjustment content that is registered in the adjustment means that registers the information input / output state, it is possible to use the information without increasing the load on the user. High-speed and high-efficiency information input / output of information between a user and a device can be realized. For example, scrolling speed of text information, playback speed of audio, amount of information of video, etc.
By adjusting to the individual difference or physical condition of the user, the sense of redundancy or oversight of information can be improved, and high-speed information reception can be realized.

01 indicates that 20% is required for reading an English sentence, 50% for translating, and 30% for inputting a Japanese sentence. Next, when the display scroll of the English sentence is advanced (the output information amount is increased) in order to increase the translation speed, the state 18
02. That is, 30 to read
%, 35% for translation, and 35% for input.
However, in the case of this user, assuming that only 60% of the brain processing capacity, that is, the width 1803, is required for translation, the translation speed decreases and the amount of input information decreases. Therefore,
The display scroll speed (output information amount) is adjusted so as to be in the state 1804. Conversely, if the scroll speed is low and the state is as shown in state 1805, the scroll speed is increased to return to state 1804.
