AI Technical Summary

Problems solved by technology

Since portable information terminals must be small enough in overall size to be easily carried, conventional key button input methods are difficult to use.

However, due to the size of most portable information terminals, a plurality of menu bars are inevitably displayed close together on the touch screen making it difficult to accurately select a desired menu, resulting in touch errors and / or erroneous selections.

Further, when such an error occurs, there is no way to correct the error.

That is, a user must typically first execute an undesired function before returning to an earlier menu to correct the error, or the touch screen does not respond to the user's input when the touch error occurs.
