Abstract

Disclosed is a user interface system without extra hardware for detecting more than three types of mouse-like click operations (e.g., a double-click with a mouse's left button) on a touch-panel attached to the operation panel of an industrial machine, ATM terminal, multi-media kiosk terminal, or some such device. Whereas a conventional touch-panel interface system, for which a single finger is used, can detect only one type of click operation on a touch-panel screen, the new system is unique in using the following two means to detect more than three types of click operations: o The length of time that one finger presses a touch-panel screen o Another finger's click selection

Touch-Panel Interface System for Detecting More than Three Types
of Click Operations

      Disclosed is a user interface system without extra hardware for
detecting more than three types of mouse-like click operations (e.g.,
a double-click with a mouse's left button) on a touch-panel attached
to the operation panel of an industrial machine, ATM terminal,
multi-media kiosk terminal, or some such device.  Whereas a
conventional touch-panel interface system, for which a single finger
is used, can detect only one type of click operation on a touch-panel
screen, the new system is unique in using the following two means to
detect more than three types of click operations:
  o  The length of time that one finger presses a touch-panel
      screen
  o  Another finger's click selection

      Fig. 1 shows the algorithm used in this system to detect clicks
with respect to time.  Its key points are as follows:
  o  A touch of sufficiently short duration is regarded as a
      double-click.
  o  A touch of sufficiently long duration invokes a pop-up-menu
      next to the position at which the finger touches the screen,
      and a second finger can select a click operation from the
      menu as shown in Fig. 2.

      More than three types of click operations on a touch-panel
screen can be detected as follows, through the use of preset periods
Ta and Tb and a pop-up-menu.
  Double-click
  o  A user presses a finger against a point on...
