Keyboard Design for Portable PCs

      Because of the size and weight restrictions, the keyboards of
the portable PCs are required to be compact.  The design though ideal
for the portability, is not exactly an ergonomic/orthopedic design
especially when considering users who routinely travel and use it for
several hours at a time.

      This invention proposes a simple but innovative enhancement to
the keyboard: namely a specially designed inflatable air-bag.

      Many people who routinely use computer (and keyboard) for long
hours in their daily work activity at home or in the office
potentially face a health hazard which can create an arthritis like
syndrome in their fingers.  This is a common form of the occupational
health hazard especially among the computer professionals.

      Proper positioning of the arm while typing can alleviate,
albeit partially, this health hazard.  Often the keyboard is made
especially larger to support the arm or a separate, long armrest is
placed by the keyboard.  Both solutions are not acceptable in the
portable PC market because of obvious reasons.

      The solution proposed is rather a bold one:  A specially shaped
long air bag can emerge from the keyboard.  The air bag will be along
the length of the keyboard.  The air bag can be made of rubber-like
material.

      If the user so prefers, at the touch of a button the 'balloon'
will pop from the edge of the keyboard.  The arm can rest on this
cushion...
