Abstract

The CrimAR application is a system using augmented reality technology and tangible interaction in presenting criminals in 3D. CrimAR allows a flexible and natural means for inspection by witnesses in the process of suspect recognition. To identify usability factors in interacting with the 3D models and to discover features and further areas of usage in criminal investigation, we conducted a usability evaluation consulting experts on both 3D interface design, and criminal investigation. The CrimAR application was very positively received by both group, and is on a whole considered a significant contribution in simplifying and improving the process of recognition. Three usability problems are identified, with solutions. Two new features deemed necessary by the investigators are introduced, and two other areas of usage in criminal investigation are proposed. A schedule for implementation and further testing of these various components are presented.
