Method and apparatus for avoiding evidence contamination at an incident scene
First Claim
1. A method for generating a guide path for an incident scene using a portable communication device, comprising:
- displaying the incident scene and evidence pertaining to the incident scene on a display of the portable communication device;
augmenting reality of the displayed incident scene with displayed selectable evidence tags, the selectable evidence tags displaying evidence attributes;
calculating a guide path that avoids contamination and damage of evidence within the augmented reality incident scene based on the evidence attributes; and
displaying the guide path as part of the augmented reality of the incident scene;
generating and displaying geofenced safeguarded areas highlighted around each piece of evidence that is vulnerable to contamination; and
sizing each geofenced safeguarded area based on evidence type and vulnerability to contamination.

Abstract
Improved incident scene investigation is provided by displaying the incident scene and evidence pertaining to the incident scene on a display of a portable communication device where the display is augmented with tagged evidence attributes and/or further augmented with geofenced safeguard areas surrounding pieces of evidence. The evidence attributes provide and display risk assessment information as to which pieces of evidence at an incident scene are vulnerable to being contaminated or damaged. The evidence attributes may further provide and display an impact factor indicator indicating whether a piece of evidence is likely to be impacted by a context factor from the incident scene. Alerts can be generated at the portable device upon approach to a geofenced safeguarded area surrounding vulnerable evidence. The augmented display of the incident scene can also redirect a user approaching a particular piece of evidence.
