 ABSTRACT

This project entails the design and implementation of an advanced AI voice assistant bot aimed
at revolutionizing user interaction through cutting-edge natural language processing (NLP) and
machine learning (ML) technologies. The voice assistant is engineered to perform a wide array
of tasks, including but not limited to setting reminders, providing answers to factual questions,
managing smart home devices, scheduling events, and offering personalized recommendations.
The system integrates state-of-the-art speech recognition and synthesis technologies to ensure
high accuracy in both understanding and generating human speech. Speech recognition
components are based on deep learning models that can adapt to various accents and speaking
styles, while speech synthesis components generate natural and expressive responses. A key
feature of the AI voice assistant is its contextual awareness, which allows it to maintain
coherent and relevant multi-turn dialogues. This is achieved through sophisticated dialogue
management systems that track the context and intent of conversations over time.
Personalization is another critical aspect, as the bot learns from user interactions to tailor its
responses and actions to individual preferences and habits.

METHODOLOGY

3.1 PLANNING AND RESEARCH

The project began with a planning and research phase, where the existing health
appointment apps were analyzed to identify gaps and opportunities. The user needs and
preferences were also gathered through surveys and interviews with healthcare providers,
patients, and administrators.

To gather user needs and preferences, surveys were conducted with a diverse group
of patients, healthcare providers, and administrators. The surveys aimed to understand the
challenges and pain points associated with traditional appointment scheduling processes and
identify the key features and functionalities that users desired in a digital health appointment
app

In addition to surveys, in-depth interviews were conducted with healthcare

providers, patients, and administrators to gather more detailed and qualitative insights.
These interviews provided valuable information on the workflows, challenges, and
opportunities for improvement in the appointment scheduling process.

The research phase also involved reviewing existing literature on patient

engagement, patient-centered care, and digital health technologies. This helped to inform
the development of the app and ensure that it was aligned with best practices and evidence-
based guidelines.

Some of the key findings from the research phase included:

a. Patients want a user-friendly and intuitive app that allows them to easily schedule,
reschedule, and cancel appointments

b. Healthcare providers want an app that streamlines their workflow, reduces no-shows,
and improves patient engagement

c. Administrators want an app that integrates with existing electronic health records
(EHRs) and provides robust analytics and reporting capabilities

ABOUT APP

4.1 BUILT WITH

 Kotlin - We developed this project using Kotlin in backend & XML to implement
designs into code. The app was developed in Android Studio. We have also used
some open-source libraries like ZXing for QR Code, Chart and some UI libraries.
 Java - As Java and Kotlin are interoperable, we used a Java class that encrypts the
user data while saving in the app storage using AES Encryption. This way we prevent
any data leak.
 Firebase - Firebase is a free tool for developers so we used it to authenticate users
using their email and perform similar operations. We also used firebase to store user
data as well as their appointment details, and etc. Not only that, we also used firebase
to store docs that are uploaded by the users (Prescriptions).
 Figma - We used Figma to design the UI / UX during the designing & prototyping
phase of our project. The design we used is minimal as well as clean. People with
colorblindness will have no issues using it.

Coroutines - For asynchronous calls and tasks to utilize threads.

 Android Architecture Components - Collection of libraries that help you design

testable, and maintainable apps.
 View Model - Stores UI-related data that isn't destroyed on UI changes.
 View Binding - Generates a binding class for each XML layout file present in that
module and allows you to more easily write code that interacts with views.
 Live Data - Live Data was used to save and store values for view Model calls and
response of method calls.
 Navigation Components - Navigation Component was used to navigate between
fragments and pass parcel able objects
 Material Components for Android - Material Components for Android (MDC-
Android) help developers execute Material Design. Developed by a core team of

DEPT OF CSE, GEC HAVERI 2023-24 Page14

 Digital Health Appointment Android Application

engineers and UX designers at Google, these components enable a reliable

development workflow to build beautiful and functional Android apps.
 ZXing - QR Code Generator - ZXing's QR Code generator library to generate QR
Code from Strings

4.2 APP FEATURES

 Appointment Booking: The user can search doctors by their name, phone or email
to book an appointment. The users have to answer some questions regarding their
issue, this way the appointment is booked.
 Appointment Sorting: We designed an algorithm that analyses the user data, makes
some calculation and sorts the patient queue according to the priority. This way
every patient gets priority equally.
 Prescription: The user uploads their latest prescription in the app, so when booked
an appointment, the doctor can check their recent prescription and hence carrying
prescription is not required.
 Statistics: The user can add and monitor their past 5 data of health reports which
is displayed using charts.
 Instant UPI: When asked about the fee amount, it sounds quite unprofessional for
doctors when they have to talk about it. But from now, the Doctor can add their
fee details and the app generates a QR Code itself.
 Appointment / Patient Queue List: The users can check their appointment list of
all doctors to which they booked appointment. The patient queue is a list that is
sorted using our algorithm and displayed.
