Nouse Phase II testing at SCO commences.

Feb-May 2007:
Over 20 additions and upgrades to the Nouse-PVI (v.1.0.1 - v.2.6.2) delivered to SCO.

Jan. 26, 2007:
Nouse-PVI (v.1.0) delivered to SCO for pre-testing.

History of Nouse development:


  • Winter: Stereo-Tracking project is launched to combine the expertise of a new member of the Computational Video group, D. Gorodnichy - a recent graduate from  University of Alberta where he worked on feature tracking for robot navigation and automated detection of eyes in photo-pictures, with the expertise of Gerhard Roth on stereo 3D reconstruction. The hope is that by using two cameras, facial feature tracking could be improved, as available at the moment face tracking techniques left much to be desired.
  • Spring: In experimenting with different facial motions in 3D,  tracking of the nose tip is found most robust compared to all other facial features. Tracking technique  specially  tailored for tracking the convex shape of the nose is then designed. First demo programs showing that it possible to write with the nose as with finger are developed.
  • 5am on a July night of 2001: after several weeks of searching for a name for the new technology, the Nouse [naus] occurs as combination of Nose and Mouse.
  • Summer: NousePaint and BubbleFrenzy point-n-shoot game developed. First public demos of writing with the nose.
  • Sept 5: "Introducing Nouse". An opening talk on the NouseTM technology made at IIT-NRC on Sept 5, 2001 - html.
  • Fall:  work on conference papers on Nouse begins.

  • May: Application for patent coincides with the birth of Dmitry's first daughter.
  • Double Blink  is conceived as a click replacement mechanism (later experiments with SCO patients showed that this technique can't be used for most of them due to eyeglasses. NouseBlink will be then proposed in 2006)


  • The idea Feedback providing cursor is conceived. First implementation (flying box with changing colours) is implemented.
  • " It is a convincing demonstration of the potential uses of cameras as natural interfaces." - The Industrial Physicist, Feb. 2003 (pdf, html)
  • Nouse is the cover feature of the August issue of Planeta Digital, Brasil ("Hope without limits", in portuguese) which rates it top over other vision-based cursor control programs.

  • NouseBoard is conceived, as a board that maps onto the range of nose motion.


  • Phase I Nouse user variability study is performed by SCO and video data provided to NRC for adapting the technology
  • NouseClick, NouseEditor is developed. Many overall improvements are made based on the data provided by SCO.


  • NouseTyper and NouseChalk are developed.
  • Nouse is delivered to SCO for testing, as Phase II Nouse testing commences.
