Pen Mouse Optical
The Optical V-Mouse takes computer navigation to another level by
combining the best of all functions into one easy-to-use ergonomic
device. And with an optical sensor instead of a track ball, you'll
never have to clean out lint and dirt.
Includes specially designed mouse pad with built-in magnetic stand
to keep your mouse upright when not in use. Because it utilizes
plug-and-play USB technology, all you have to do is plug it
in.

Software included:
RitePen: www.evernote.com
The ritePen can turn any handwritten words and sentences into text,
as well as symbols and numbers. The ritePen will recognize cursive,
print, or a combination of print and cursive writing and change it
from a hand written note into text. The software does not have to
be trained.
RiteMail: www.evernote.com
RiteMail gives users the option of taking endless pages of
handwritten notes and sending handwritten e-mails. riteMail also
provides a "copy" and "copy to text function", which can be used
for signing electronic signatures (*copy signature written on
riteMail to any text based program that requires a signature) and
changing the entire handwritten notes to text. The program even
offers a "Shape Up" feature that automatically changes hand drawn
shapes into more neatly designed shapes.
Web-Memo (Finger IE Memo):
This is a truly unique program that allows the users to draw notes,
highlight areas of interest and capture items displayed on a web
page. If there is an interesting article the user would like to
share with his/her friends, the user can make notes or highlight
right on the web site. The user, then, can send the captured
note(s) in the e-mail.
Finger White:
The Finger White works like the Web-memo. However, instead of being
able to highlight, take notes, and capture those notes right on a
web page, the Finger White will allow the user to draw notes,
highlight areas of interest and capture images in any program, a
phenomenal tool for professionals who give lectures and
presentations.
All the above is now possible with this invention...
