Objective To examine the impact of an investigative checklist on evidence collection by police officers responding to a routine burglary investigation.

Methods A randomized control trial was conducted in virtual reality to test the effectiveness of an investigative checklist. Officers in the randomly assigned treatment group (n = 25) were provided with a checklist during the simulated investigation. Officers in the control group (n = 26) did not have access to the checklist at any time. The checklist included five evidence items commonly associated with burglary investigations.

Results Officers who were randomly provided with an investigative checklist were significantly more likely to collect two evidence items located outside of the virtual victim’s home. Both treatment and control officers were about equally as likely to collect three evidence items located inside the residence.

Conclusions Investigative checklists represent a promising new tool officers can use to improve evidence collection during routine investigations. More research is needed, however, to determine whether checklists improve evidence collection or case clearances in real-life settings. Virtual reality simulations provide a promising tool for collecting data in otherwise difficult or complex situations to simulate

CVG-HOLO – WAYFINDING HOLOGRAM PROJECT

XR-Lab is working with Cincinnati/Northern Kentucky International Airport (CVG), in collaboration with UC Center for Simulations & Virtual Environments Research, to

  1. Develop and demonstrate a wayfinding hologram.
  2. Evaluate the hologram signage’s performance to augment passengers’ wayfinding experience.
  3. Develop concepts of Concourse-B store renovation, integrating emerging digital technologies related to Extended Reality
  4. Develop a digital twin model of the CVG Concourse-B store area.

The project will apply various methods, including eye-tracking, motion capture, motion tracking, and computer vision.

Tian. J., Tang, M., Wang. J., The effect of path environment on pedestrian’s route selection: A case study of University of Cincinnati..  27th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA). Sydney, Australia. April. 2022. 

The present study on the influence of the path environment on pedestrians’ route selection is mostly concentrated on the urban level while rarely discussed from the architectural level. Taking the University of Cincinnati (Ohio, US) as an example, this study aims to investigate whether the difference in the environmental settings of the route will affect pedestrians’ walking experiences and future route selection, with the ultimate goal of ascertaining the underlying relationship between the route environments and the user behavior in the process of route selection and implementation. This study selected three routes from the Langsam library to the CEAS library. The research methods included data analytics, questionnaires, and comparative analysis. Firstly, through surveys and an E4 wristband, psychological and physiological data were collected. Secondly, Analysis of Variance (ANOVA) was used to examine whether there was a significant difference in pedestrians’ walking experience among the three routes. Thirdly, through the analysis of questionnaires, the factors that play an important role in pedestrians’ route selection were determined. It can be concluded that the three routes with different environmental settings bring a different experience to participants. More specifically, the level of comfort and openness of the route significantly affects the route selection of pedestrians, while the degree of fatigue during walking does not. To sum up, for the transition space from outdoor to indoor, the factors affecting pedestrian route selection include the route’s degree of comfort and openness.
