Abstract

Disclosed is a system for an ergonomic keyboard which provides computer users with comfortable and safe typing work. This keyboard detects not only the number of typing strokes but also the intensity of typing (i.e., typing pressure). If a user continues with intensive typing, the keyboard detects an intensive threshold which can be specified by the users, and warning message(s) will be issued to alert the user. This feedback system can help to prevent computer users from occupational diseases such as Repetitive Stress Injury (RSI).

Ergonomic Keyboard with Warning Function

      Disclosed is a system for an ergonomic keyboard which provides
computer users with comfortable and safe typing work.  This keyboard
detects not only the number of typing strokes but also the intensity
of typing (i.e., typing pressure).  If a user continues with
intensive typing, the keyboard detects an intensive threshold which
can be specified by the users, and warning message(s) will be issued
to alert  the user.  This feedback system can help to prevent
computer users from  occupational diseases such as Repetitive Stress
Injury (RSI).

      The Figure shows an example of this system.  The keyboard
detects the number of typing strokes and the intensity of typing, and
if an upper limit of a continuous intensive typing is reached, a
warning message from the speaker on the keyboard and/or a warning
flash on the  Light Emitting Diode (LED) of the keyboard will be
issued.  Another example of the warning is a pop-up message on the
display of Personal Computers (PCs) and/or auditory feedback from the
speaker of the PC.  Three examples for detecting the intensity of
typing are introduced:
  1.  Use Force Sensitive Resistors (FSRs) which are equipped
       on the matrix sheet of the keyboard.
  2.  Use acceleration sensors which are equipped inside the
       housing of the keyboard.  The acceleration sensors detect
       the shock caused by typing, because the shock is related
