## 4 Case Study
### Typical Reporting Process  
The prototype iInspect app (Figure 8) developed in this study for smartphones using Android did not include functions (such as account management or other functions) that were not directly related to the verification The researchers presumed that an iInspect user had previously downloaded and installed the prototype and had set up a user account. In addition, iInspect is able to use GPS information from the smartphone to determine if a user has entered a building where inspection information for the building has not previously been downloaded using the app--in such a case, the app will be able to prompt the smartphone user to download inspection information for the building from the external server to view any possible inspection tasks.

When an inspect user is near a fire safety-related facility, the system will push a notification to the user, and an overview of checkable facilities will be displayed on the phone that contains additional information about the facilities to be checked. As shown in Figure 8a, each bubble in the floor plan represents a certain type of facility available for inspection; when a bubble is selected, the basic information about the associated facility and the amount of reward money for the inspection task will displayed at the bottom of the screen.  
After clicking the \"Go\" button, iInspect will show an interface of indoor navigation to guide the user to locate the facility, as shown in Figure 8b. The \"VR\" and \"BIM\" buttons in the navigation view allow the user to switch between the BIM view and the VR view if a VR view is available.

If the \"Inspect\" button is clicked, a checklist will be displayed, as shown in Figure 8c. By clicking the \"i\" icon in front of each item, a detailed explanation and the associated illustrations will be displayed at the bottom of the screen. If the user believes there is a violation for a given item and clicks the \"cross\" icon, the system will require a photograph to be uploaded as proof of the violation. If all items pass the inspection, the system will prompt the user to upload a photo of the entire facility along with a timestamp as proof of the inspection.  
A participant can upload an inspection report to the server by clicking the \"Done\" button, and fire safety management officers will be immediately notified if any safety violation is reported. As mentioned previously, an inspection report will be rated, and the RS and monetary reward (\(M\)) will be calculated. An inspect user can view his/her account to check the value of the RS and the balance of \(M\), as well as the history of inspections, as shown in Figure 8d. Inspection details will be displayed (Figure 8e) after the participant clicks any inspection history record. In addition, the ranking of the user with respect to his/her friends (Figure 8f) will also be displayed, and this information is shared on social media.
