Nouse® Perceptual Vision
nose as mouse. Open your mouth for click. As simple as that.
Work with a computer hands-free, using your computer's webcam!
Gear-free, sub-pixel precision, robust to any head motion,
Highly configurable, full mouse functionality, with built-in
customizable onscreen keyboard,
Hands-free mouse alternative, which is as powerful and as it is
affordable! (See demos at left).
All this is possible with Nouse®
Perceptual Vision Interface technology,
which stands for 'Nose
as Mouse', pronounced ['naus],
and is a Canadian invention that made a difference in lives of
many people (Read
and superior to competitors, thanks to its five(!) scientific and
and extreme level of testing and customization performed in partnership
with Saint Vincent Hospital, Bruyere Research Institute, and Department
of Rebilitation Science of Univerity of Ottawa.
Nouse technology has been officially approved by the
Ontario Ministry of Health and Long-Care and added to the Ontario's
Assistive Devices Program (ADP) Product

Nouse is still in the prototype phase but Dmitry hopes it will be
available for everyone to use whether it be as an alternative to the
keyboard or for gaming. Just like its predecessor the mouse back in the
1960s, the Nouse was created to make computer operations easier for
