Portuguese law enforcement organizations currently face a significant technology gap. Research has shown that some law organizations, such as Polícia Judiciária (PJ) and Polícia de Segurança Pública (PSP), often criticize the lack of technology to support the Police work in all kinds of fields, from criminality prevention to minor infractions. This study aims to determine how augmented reality (AR) technology can be used to ease/improve the day-to-day tasks of the law enforcement forces and how do the end-users perceive this new type of information. Based on a review of the literature and implementations on AR technologies to aid law enforcement organizations, a proof-of-concept smartphone application was developed in order to aid the police infraction ticket issuing process. The developed solution was analysed to infer its usability. As such, various users tests were conducted with a total of thirty users including police personnel and nonassociated users. The users were then asked to answer a questionnaire contemplating the System Usability Scale (SUS) questions. The responses were analysed and then combined with the Quantitative Evaluation Framework (QEF) in order to extrapolate the proof-of-concept’s final value. The results suggest that the ticket issuing process was fully integrated in the proofof-concept and was well received amongst the users. The system contemplates the possibility to scale to other devices other than the smartphone, for example surveillance cameras or wearables, as well as including new features to perform different tasks such as recognizing vehicles through AR and Depth.
