Crime Scene Investigation. Story

Transcription

1 Crime Scene Investigation Story Joe works as Detective in the Crime Scene Unit (CSU), which is a part of the SPD Detective Bureau's Forensic Investigations Division in Smallville City Police Department. He usually begins his shift by checking out his Case list. He chooses the Case, which he currently work on, checks and update information about it. Some information is stored in Police database, and some information on the case is conducted on paper (such as Reports, Notes etc.). Therefore, Joe has lots of paper work to do, which is boring and takes a lot of time. When Joe needs to find some specific information on the Case he must look through lots of papers, which also steals his precious time, which he could spend investigating crimes. Joe does some investigation activities, than adds some new Evidence / Suspect info / interrogation of suspect s records when he is back to Police station. He would like very much to have simple application on his smartphone or tablet, so he could record, update and overview crime cases he responsible of, even from remote locations. Application would enable CSI professionals and police officers to glance at their current cases and get more detailed information and status of every case. App would contain structured information of every case, including evidence list, crime scene information, suspect profiles and witnesses records. It enables to upload pictures and video related to the case. New Lab researches also can uploaded to corresponding case. When enough evidence collected and suspect can be charged with a crime, the Case is referred to court. Officer change case status and paste all materials to District Attorney. In addition, if Joe could see statistic of his solved/unsolved cases as simple graphic feature of this app, it would greatly motivate him to improve his efficiency.

4 Point of View Joe West, the Detective in Smallville Police Department needs a way to record, update and quickly overview all information about his every Case (even from remote locations) so than he could concentrate on investigation process. Mock Up A Design for the application was created using the Prototyping kit. In my Application, I used Split Screen Layout. Master Page (on the left side) contains Cases that is being investigated by detective. It shows short information about the Case, such as ID, short description, classification, Status, date and address of the Crime. Detail Page (on the right side) contains more detailed information about the Case. Information grouped and structured with Icon Tab Bar. Each Tab contains corresponding amount of information, which can displayed when you switch tabs.

5 Incident Overview Tab displays Case overview. Attachments Tab displays different attachments files related to selected Case, such as Photo, images, video files, text protocols. Notes Tab displays Notes, done by Detective while Investigation process.

6 Related Persons Tab contains detailed information about Persons involved in the Case, which divided by following groups: Suspects, Witnesses and Victims. By clicking on person, listed here, you will navigate to that person s Profile page, which contains all available information about that person.

7 Lab Research Tab contains information about Evidence, which was found at Crime scene and transferred to Police Laboratory for research. Pictures of such evidence and Lab research results displayed here. Study Link to my Study: ch/participant/3f977e3fa23f1d370babfba0 Link to my PROTOTYPE (Suspects and Witnesses Details pages added): otype/snapshot/latest/index.html#/ _s0 SAP Web IDE App Navigation I exported my App Project from BUILD tool and used mock-data for my CSI app as recommended. For better understanding, I will explain names of my application s pages: Master Page _S0, Detail Page _S1, Witnesses Details Page _S3, Suspects Details Page _S4. Here I will demonstrate and explain navigation from Involved persons Tab of the Detail Page ( _S1) to Suspects Details Page ( _S4). Therefore, in order to connect those two screens, we need to choose navigation area of the Details Page (in my case, it is Column List Item, which I highlighted with yellow color). Then, on the right side in Web IDE, I chose Events Pane and selected one of existing

8 Event handlers from the controller: _onpressnpsapmcolumnlistitem m. This event handler triggers navigation to Suspects Details Page, which we will see when we Go to Code in the corresponding controller.js file. As we can see in code, this event handler triggers navigation to _S4 - Suspects Details Page. SAP Web IDE App Implementation I will demonstrate the implementation of additional Tab Filter (Reports Tab) and will add Feed Input Control, which will serve as Create & Send Report feature. 1. Open Detail Page ( _S1) in Layout Editor 2. From the Controls tab on the left, drag&drop new Icon Tab Separator, after that drag&drop new Icon Tab Filter

9 3. In Properties Pane on the right, I changed Icon and Icon Color, so it would more correspond to Reports Tab. I also removed Text and Count of the Tab Filter using Properties Pane. 4. From the Controls tab on the left, I dragged Feed Input Control and dropped it under the corresponding Icon Tab Filter (my new-added Report Tab). After that, I have chosen Feed Input Control by clicking on it and made changes in Properties Pane on the right (such as: changed default icon and default text). 5. After that, I Saved changes and Run my CSI project in Preview mode with mock-data, which I made. All changes saved successfully and we can see new customized Tab Filter with Feed Input control in it, displayed in Preview mode.
