Abstract
Biometric feedback systems and methods for measuring user reaction to the indoor or outdoor environment are described. In some embodiments, one or more user(s) wears a body-worn sensor and the user's heart rate variability or other indication of stress is monitored as the user travels along a pre-determined route.
Claims16
A method of ascertaining autonomic stress relative to a location comprising:
- a) using a plurality of biometric sensors to ascertain autonomic stress over time from a plurality of subjects while the plurality of subjects move about a plurality of locations;
- b) using a plurality of location sensors to track the locations of the plurality of subjects over time while the plurality of subjects move about the plurality of locations, at least some of said subjects at least partially overlapping locations;
- c) generating and displaying a heat map which indicates elevated autonomic stress by shading to depict the autonomic stress by geographic location along a particular route to correlate at least some of the plurality of locations with an autonomic stress level, wherein the shading is graphically depicted as continuous and non-gradated along the particular route;
- and
- d) physically altering the environment at one or more of the geographic locations, wherein each subject is wearing a respective biometric sensor and a respective location sensor during steps a) and b.

A method of assigning autonomic stress to a location comprising:
- a) using a plurality of heart rate monitors to collect heart rate data from a plurality of subjects over time while the plurality of subjects move about a travel path, each subject wearing a heart rate monitor;
- b) using a plurality of location sensors to track the location of the plurality of subjects over time while the plurality of subjects move about the travel path;
- c) grouping the heart rate data based on location and filtering out physically-induced stress from the heart rate data, said step of filtering out physically-induced stress comprising calculating each subject's heart rate variability and applying an algorithm to the heart rate data;
- d) displaying on an electronic screen a heat map which indicates elevated autonomic stress by shading to depict autonomic stress levels for a plurality of geographic locations along the travel path based, at least in part, on step c), wherein the shading is graphically depicted as continuous and non-gradated along the travel path;
- and
- e) physically altering the environment at one or more of the geographic locations having an autonomic stress level, wherein each subject is wearing a respective heart rate monitor and a respective location sensor during steps a) and b).
