3 Abstract Severe Mental Illness is one of the rising cause of concerns throughout the world. In India, the family members of an individual suffering from SMI (like bipolar disorder, Schizophrenia, etc.) play a significant role in the treatment and lifelong management of their illness. The family caregivers face remarkable challenges in providing appropriate support to the person suffering from SMI due to lack of understanding and knowledge about the illness. In this project, we aim to fill the knowledge gap for the family caregivers of the individuals suffering from Schizophrenia by developing an android application - Information Capsule. This application will serve as a communication point between the doctors and the caregivers by providing medically authentic information about the disorder in Hindi and providing the caregivers with an opportunity to post their queries. Keywords: Design, Human Computer Interaction, Android, Nodejs, SMI, Schizophrenia

6 Chapter 1 Introduction Recovery from an illness involves not only getting better, but also achieving a full and satisfying life. Education can accelerate your recovery process in that it broadens your intellectual, social and emotional horizons. When you go to classes, you not only have an opportunity to expand your knowledge on a wide variety of topics that interest you, but you also have a chance to meet new people. Completing tasks and graduating from courses can give you a sense of pride in your accomplishments. Education can also further your goals in other areas of your life as well - it can help you get a job, and it can help you understand more about things that impact your life such as finances or health. The task of educating a mentally challenged person can be daunting. The usual methods of teaching and overseeing might not necessarily apply, and you may encounter frustrating moments in which you feel you are getting nowhere. It s important to know and understand a person s disability and learn to work within its confines, rather than expecting the disability to go away. Learning a person s strengths and helping him/her compensate for weaknesses will play a important role in fostering success. Most of the people feel, they move from not knowing to becoming more aware of themselves and their place in the world as they gradually recover. This has been called cluing in (Schreiber 1996). People became clued in in all manner of ways, and this cluing in actually helped them to be more positive about themselves. 1.1 Problem Statement Severe Mental Illness like Schizophrenia and bipolar disorders involve lifelong management of the illness. Individuals suffering from SMI are dependent on their family from early symptoms detection to treatment initiation and psychosocial support. Right now, many caregivers have limited knowledge about the kind of disorder their patient is going through. They are not able to manage the illness, react appropriately in a given situation (manic episode) and answer the queries their patients have regarding the illness. So, why not educate these caretakers to act as a communication gap between the doctors and the patients for any kind of information? Our application focuses on the patients dealing with Schizophrenia. It is not a terribly common disease but it can be a serious and chronic one. It often includes psychotic experiences, such as hearing voices or delusions. Although schizophrenia is not as common as other mental disorders, it can be very disabling. Approximately 7 or 8 individuals out of 1,000 will have schizophrenia in their lifetime. Worldwide about 1 percent of the population is diagnosed with schizophrenia, and approximately 1.2 of Americans (3.2 million) have this disorder. 1

7 1.2. OBJECTIVES 1.2 Objectives My application will lay emphasis on important features that would be easily understood by an average person and will contain important information that can prove to be useful for the recovery of a particular patient dealing with Schizophrenia. Create an android mobile application containing static information articles about Schizophrenia. What is Schizophrenia? Causes of Schizophrenia Symptoms of Schizophrenia How to diagnose Schizophrenia? Prevention from Schizophrenia Misconceptions about Schiziphrenia Allow the user to mark his/her favorite articles and also remove them as favorites. This will ensure that important information is never lost and always secured for later visits. Allow the user to enter the patient s personal information like primary and alternate contact numbers in case of any emergencies. Maintain a local logs database of all the interactions the user makes with the application and periodically sync it with the main server database. Maintain a local logs database of all the questions asked by the user and periodically sync it with the main server database. Allow the user to post their queries. Create an IVR (Interactive Voice Response) system where the user can directly call at a helpline number for any kind of questions and answers. Maintain the application to work under offline circumstances as well. (IVR calling, logging, etc.) 2

8 Chapter 2 Features 2.1 Google Authentication A person opening our application will be asked to authenticate his identity using his Google account. This is done with the help of the Google Drive API using GoogleApiClient provided by Google. To integrate Google Sign In in our project, there is a certain process that needs to be followed if we want to make authorized API calls: Create your Android Project. Generate the SHA1 Signing certificate In a terminal, run the Keytool utility to get the SHA1 fingerprint for your digitally signed.apk file s public certificate. The Keytool prints the fingerprint to the shell. For example: Register your application with Google API Console Open Credentials Page Click Create credentials OAuth client ID. 3

9 2.2. FAVORITE ARTICLES CHAPTER 2. FEATURES Select Android. In the Package name field, enter your Android app s package name. Paste the SHA1 fingerprint into the form where requested. Click Create. 2.2 Favorite Articles A user will browse through the all the articles and will have an option of either saving that particular article for later use or removing it from his/her favorites list. The artciles are shown using a RecyclerView library provided by Android. The cards in the Recycler View are placed side to side in a GridViewLayout using GridViewLayoutManager RecyclerView Android RecyclerView is more advanced version of ListView with improved performance and other benefits. Using RecyclerView and CardView together, both lists and grids can be created very easily. Below is the RecyclerView widget with necessary attributes. After adding the RecyclerView widget, we need the adapter class to render the data. RecyclerView adapter is same as ListView but the override methods are different. The GridView Layout GridView layout in one of the most useful layouts in android. Gridview is mainly useful when we want show data in grid layout like displaying images or icons. This layout can be used to build applications like image viewer, audio or video players in order to show elements in grid manner. 4

10 2.3. EDIT PROFILE CHAPTER 2. FEATURES 2.3 Edit Profile If a user sign In for the first time, he/she asked to fill his/her personal details on Edit Profile page. Here, we are obtaining some information of the person directly though his Google account His name using getsigninaccount().getdisplayname() His id using getsigninaccount().get () His profile image using getsigninaccount().getphotourl() His unique Google Id using getsigninaccount().getid() The rest of the information on the edit profile page such as Gender, Age, Primary Contact and Alternate Contact needs to be filled in by the user. This information is being stored in SharedPreferences Shared Preferences SharedPreferences is an API from Android SDK to store and retrieve application preferences. SharedPreferences are simply sets of data values that stored persistently. Persistently which mean data you stored in the SharedPreferences are still exist even if you stop the application or turn off the device. 5

11 2.4. HINDI LOCALE CHAPTER 2. FEATURES 2.4 Hindi Locale Our whole application is in Hindi language to cater to the needs of the caretakers working in Indian hospitals. By default the language is in Hindi and there is no option of changing the language. To change the language of the application, you need to change the locale of the application. One of the examples is given below. 2.5 Logging Currently, all the logs of the interactions done by the user are being stored on the local DB Sqlite provided by Android. Also, all the user personal details including his Google Id are being stored on the main server. Apart from the interactions, all the questions asked by a particular user are also being stored on the local DB. For the server side requirements, I am using node.js. Node.js is a server-side platform built on Google Chrome s JavaScript Engine (V8 Engine). The following is being stored on the User Logs Table : TimeStamp, User s Google Id, User s Id, Log data The following is being stored on the User Info Table : User s Google Id, User s Id, User s Gender, User s Age, User s Primary Contact Number, User s Alternate Contact Number, User s saved articles The following is being stored on the User Questions Table : TimeStamp, User s Google Id, User s Id, Question asked by the user 2.6 Retrofit To make server API calls, I am using Retrofit. interface. For example : Retrofit turns your HTTP API into a Java 6

13 Chapter 3 Implementation 3.1 Details Meetings with doctors My PhD mentor conducted several meetings with doctors working at the psychiatric ward of AIIMS, Delhi. Some of the key inputs given by the doctors : Application should be in Hindi Minimum number of views should be there in the application. Every required feature should be right in front of the eyes and the user should not get confused. After conducting few focus groups with the caregivers, some of the key inputs that came to light were : Only required information should be present Minimum user input Application should be in Hindi language Minimum number of clicks Audio calling feature is a must Low Fidelity Prototypes There were ateast 3-4 iterations of prototyping to reach the final result. The first iteration was the hand drawn mockups where I designed the wireframes according to the inputs retained from the surveys. 8

14 3.2. FINAL PROTOTYPES CHAPTER 3. IMPLEMENTATION The second iteration involved the making of the low-fi greyscale prototypes in Adobe Photoshop without any icons or colors. The third iteration was the improvement of the 2nd iteration greyscale prototypes. Most of the design changes took place in this iteration. The fourth and the last iteration involved the use of colors and icons. The final workflow was fixed in this iteration Coding After the final iteration and taking approval from my advisor, I started the coding phase of the application. I used Android Studio for the frontend part along with Node.js for the server side requirements. 3.2 Final Prototypes After a lot of iterations of low fidelity and high fidelity prototypes, we came up with the final prototypes that has been implemented in the current version of my android application Phase 1 Prototypes 9

18 Chapter 4 Discussion 4.1 Conclusion In the first part of the BTP, I had developed most of the features including favorite articles, edit profile, google authentication sign In. I developed a lot of knowledge about Android Studio and its components. On the frontend side, learned about many Android components such as Recycler View, Grid View Layout, Edittext, Floating Buttons, Menu options, etc. On the backend side, learned about SQLite database in Android, how to log entries into the database, Retrofit library used for making API calls to the server, network scheduling, services, etc. In the second part of my BTP, I have developed the QA part where the user can post their queries. I have created the functionality of creating the CSV in the internal memory of the phone of all the logs of user interactions and user questions. Also, I have added the functionality of periodically syncing these logs with the main server. Apart from that, I have replaced the cover images of all articles with my own images. The application is currently up on the server and will be deployed on Google Play Store in coming 2 weeks. It has been given for review to doctors working at AIIMS, Delhi. Their inputs along with new features will be incorporated in the next part of my BTP. 4.2 Future Work In next phase of the BTP, I plan to develop IVR calling feature, personal discussion forum and FAQs page. With each consecutive development, I plan to conduct user studies and based on those user studies, I will do a complete qualitative analysis on the results to write my research paper. 13
