Home Security: The Psychological Threshold, explores how a thoughtful, intelligent product design solution can psychologically affect two user groups (homeowners and intruders) into opposing emotional states; safety and intimidation.

Using available statistical data and research on home burglaries, as well as inspiration from nature, present day solutions, and the environment, a conceptual security system was designed to meet the needs of suburban homeowners.

The central product, a security system, employs the use of lighting notifications to create a variety of reactive states and monitor individuals who approach a home. Based on the users intentions the monitor can; notify surrounding people about a potential threat, signal authorized or unauthorized entry to the home, and alert others to a crime in progress.

The resulting system is titled, Threshold. The Threshold system provides a variety of emotional responses for users. A sense of comfort to the occupant of the home and community, and a warning to perpetrators considering committing a crime through the system's universally understood visible functions.
