Pen Mounted Microphone for Pen and Tablet Computers

       The invention disclosed here enables the acquisition of
high-quality speech from the user of a pen-and-tablet system, without
the use of a headset-mounted microphone. The essence of the invention
is the placement of a microphone in the pen of a pen-and-tablet
system.  The invention is applicable to both tethered and wireless
pens.

      Speech is of strategic importance as a way of getting
information into a computer, either for controlling the computer or
for storing and/or transmitting the speech in digitized form.  Speech
and pen input are especially powerful in combination, because of
their complementary nature.
           Pen input is particularly suitable for selection tasks
where high accuracy and speed are required, such as selecting an item
from a menu that can fit on a screen.
           Speech input is particularly suitable for selection tasks
where the number of choices is too large to be displayed, such as
specifying a file name.
           Pen input is particularly suitable for two-dimensional
graphical input, such as editing by means of proofreader's marks.
           Speech input is particularly suitable for input of whole
words, phrases, and sentences, such as dictation.
           Pen input can also be stored and/or transmitted in
digitized form, such as for freehand graphics or document annotation.
           Speech input can also be stored and/or transmitted in
digitized form, such as for voice mail or document annotation.

      Speech and pen input are sometimes required simultaneously:
for example, an application may call for the user to point with the
pen while giving commands using speech.  The invention described here
is not intended for applications where speech and pen input are
required simultaneously or in rapid alteration.

      Conventional microphone arrangements are not suitable for a
pen-and-tablet system.
           A tablet-mounted microphone is undesirable, because the
tablet is relatively far from the user's mouth and is not in a fixed
relationship to the user.
           Any separate microphone, whether hand-held, head-mounted,
or lavalier, is undesirable because it adds clutter, weight, and
manufacturing cost.
           A separate hand-held microphone is further undesira...
