Story

Introduction

1.1 Motivation

Paralysis patients often face significant challenges in communicating with their caregivers due to their limited mobility and speech impairments. This can lead to frustration, isolation, and a reduced quality of life. However, advancements in technology, particularly in the field of Internet of Things (IoT), have the potential to revolutionize healthcare for paralysis patients by enabling improved communication, remote monitoring, and timely alerts to caregivers.

1.2 Objectives

The primary objectives of this project are:

To enhance communication between paralysis patients and their caregivers, enabling patients to express their needs and concerns more effectively.
To increase independence for paralysis patients by providing them with a user-friendly system that allows for hands-free operation.
To provide timely alerts to caregivers in case of emergencies or changes in the patient's condition, ensuring prompt and appropriate care.

1.3 Background

Existing healthcare systems for paralysis patients often rely on traditional methods, such as letter boards or eye-tracking devices, which can be time-consuming and labor-intensive for both patients and caregivers. The advancements in IoT technology, including the use of sensors, microcontrollers, and wireless communication, have enabled the development of more efficient and user-friendly systems for remote health monitoring and communication.
