What is an "Intype" you use daily?

 
Project Abstract - Research
 
The Intypes (Interior Archetypes) Research and Teaching Project, initiated in 1997 at Cornell University, creates a typology of contemporary interior design practices that are derived from reiterative historical designs that span time and style and cross cultural boundaries. The argument for the significance of a typology of historic and contemporary interior design practices is based on eleven years of experiments that have already produced approximately 70 archetypes developed by the principal investigators and graduate students. Intypes identify contemporary design practices that have not been named, thereby providing designers with an interior-specific, history-specific, and contemporary design-specific vocabulary. The project also offers an innovative approach to further design criticism and design sustainability. The Interior Archetypes Project produces a new knowledge base for the creative dimension of design. It is the first project of its kind to assemble contemporary design theory in a searchable database using primary source imagery. The key deliverable is its web site—www.intypes.cornell.edu.
 
INTYPE - in definition
Intypes represent ideal examples of a historical and culturally determined practice of design internationally; identify contemporary design practices that have not been named; provide designers with an interior-specific, history-specific, contemporary design-specific vocabulary; provide a new knowledge base for the creative dimension of design; offer an innovative approach to further design criticism and sustainability studies.
For Example:
CAMOUFLAGE:
Camouflage refers to the application of a consistent pattern to the wall, floor, and ceiling planes, as well as furnishings. Wrapping the interior with a continuous pattern effectively blurs the transition between horizontal and vertical planes or between planes and furnishings.
