Augmented Reality Investigation Challenges

Augmented Reality Investigation Challenges

Augmented Reality (AR) presents an opportunity and a challenge for investigators. AR adds or subtracts information so as to make the human sensory impression of a phenomena more effective. In the first instance AR may be used to find and actuate qualities in evidence. It may also be applied to locate and more clearly communicate digital evidence that is obscured within a context or meaningless without a context. Visualisation tools and court room walk through presentations are examples of the application of AR. All manner of digital evidence is collected by AR devices such as surveillance cameras, mobile phones, and so on, after processing the evidence may also be presented in digital formats. AR allows the investigator and the expert witness to augment the evidence to emphasis the key points in the same way that AR is used in sports reporting. Such capabilities are advantageous; however, they also carry similar risks as advertising where AR can distort the real to such an extent that the representation becomes factually incorrect. The presentation of scenarios by providing the court room with headsets so each member can virtually walk through a crime scene, by managing views, and drilling down on items of interest. By pointing to a blood splatter or bullet holes the user is able to tag points of interest, access information, and build a 3D visualisation of the crime scene. Documentation may also be included with video and audio tracks. This sort of virtual record may be entered into the court room for projection onto screens or goggles, have AR overlays, providing the opportunity to virtually walk through crime scenes.
