Abstract

A portable communication device receives evidence information pertaining to an incident scene along with a plurality of incident scene contextual factors pertaining to the evidence information and the incident scene. An optimum search pattern is calculated and displayed as part of an augmented reality of the incident scene. The contextual factors can be weighted to generate an optimum search pattern, such as for different individual user-investigators working at an incident scene or for certain tools being used at an incident scene.

Claims

1. A method of searching an incident scene, comprising:

displaying an augmented reality view of the incident scene to a display of a portable communication device;

calculating a search pattern based on context factors pertaining to the incident scene;

adjusting the displayed calculated search pattern based on attributes associated with each individual investigator and

displaying the calculated search pattern as part of the augmented reality view to the display.

2. The method of claim 1, further comprising:

adjusting the displayed search pattern based on weighted factors associated with different context factors.

3. The method of claim 1, further comprising:

assigning the calculated search pattern to an investigator based on user context; and

transferring the calculated search pattern to another more appropriate investigator based on user context.

4. The method of claim 1, further comprising:

automatically requesting, via the portable communication device, a specialist for predetermined types of evidence.

5. A portable communication device, comprising:

a controller for receiving evidence information pertaining to an incident scene along with a plurality of incident scene context factors pertaining to the evidence information and the incident scene, the controller calculating a search pattern in response thereto based on attributes associated with an individual investigator; and

a display for displaying the calculated search pattern as part of an augmented reality of the incident scene.

6. The portable communication device of claim 5, wherein the incident scene context factors comprise:

weather forecast, evidence type, incident scene type, individual resources, tools, and time associated with the incident scene.

7. The portable communication device of claim 5, wherein the calculated search pattern is adjusted and displayed based on weighted factors associated with different context factors.

8. The portable communication device of claim 5, wherein the calculated search pattern is adjusted and optimized based on real-time changes to the incident scene.

9. A communication system, comprising:

an evidence database for storing evidence context information entered during an initial walkthrough of an incident scene;

a search pattern calculation engine for generating a calculated search pattern based on contextual information pertaining to the incident scene, the stored evidence context information, and based on attributes associated with each individual investigator; and

a portable communication device having a display for dynamically displaying and updating an augmented reality of the incident scene including the calculated search pattern, the calculated search pattern being updated in response to changes in the contextual information of the incident scene.

10. The communication system of claim 9, wherein the portable communication device communicates with the evidence database over a wireless network.

11. The communication system of claim 9, wherein the portable communication device comprises one of:

a heads mounted display (HMD), a smart watch, a portable radio, a smart phone, or a tablet.

12. The communication system of claim 9, further comprising:

databases having stored user-investigator context information for a plurality of user-investigators; and

the communication system transferring the calculated search pattern to a more appropriate user-investigator upon arrival of that more appropriate user-investigator to the incident scene.
