Input Method for Considering Human Response-Time

      Disclosed is a method for considering human response-time in
selection from a menu.

      Selection from a menu is an effective input method wherein menu
items are displayed and one of the items is selected.  When the
number of items is large and they cannot all be displayed
simultaneously, the user must iteratively select and display items to
reach an item that he or she wants to input.  The disclosed method
solves the following problem related to this case.

      An example of the case is handwritten input of the names of
states in the USA.  The Figure shows the candidate display when a
user writes "M", and "i".

      If the user selects a state after writing "i", the selection
occurs in one of the intervals A, B, and C. Interval B shows the
human response time, which is the time needed to look at the display,
judge which item to select, and move the arm and hand.

      A problem may occur if the user selects "Missouri" in interval
B: it is possible that the user wants to select not "Missouri," but
"Michigan." The reasons are that (1) the human response time has not
elapsed since the display of the second candidate, and it is
therefore
not possible for the user to respond to it, (2) the user may find
"Michigan" while writing "i", and point to "Missouri," which is
displayed
in the same position as "Michigan." However, since the user has input
"Mi," the existing methods interpret the operation...
