# A Helping Hand to the Elderly: Securing Their Freedom through the HAIE Framework
## 2 Literature Review
IoT-enabled services in the health sector are essential for patients since doctors often have to treat patients from remote locations during pandemic situations, such as the one we are currently experiencing with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [6]. The linked gadgets can aid in surveillance and disease control, as well as track dietary needs, mental well-being, self-care, and emergency services, leading to an efficient health management system. Alzheimer's disease is the most common cause of dementia, which refers to a progressive decline in thinking, behavioral, and social skills that impairs a person's ability to function independently [25]. Information and communication technology (ICT) may, however, overcome these limitations by better capturing the symptoms of Alzheimer's disease. Researchers have looked into the use of various sensors, such as video monitoring systems or audio analysis, for evaluating individuals with dementia and mild cognitive impairment (MCI). Sometimes, people worry about their elderly family members who live alone. These individuals conduct difficult tasks by themselves to survive, which can be difficult given their age. To address this issue, many IoT devices are being developed, such as the Raspberry Pi IoT device, specifically designed for elderly people. It has seven motion and temperature-humidity sensors, which are located at seven points within an elderly person's home [26]. Because of the rapidly aging population and the attendant issues in health and social care, assistive living has become a focal point. Reducing the cost of healthcare without compromising the quality of service is the main agenda of the regime. The research proposes the smart healthcare monitoring system (SW-SHMS) to address the issues of delivering home-based healthcare monitoring while avoiding hospitalization [24]. This study aims to organize the most recent data on AiP technology that supports older individuals living in communities in their daily activities. These studies examine the effects of various technologies on older people who live in their communities while taking several health-related outcomes into account [27]. The value of employing a social robot was examined in two distinct studies: in therapy sessions for children with autism spectrum disorder, and in older adults' participation and social interactions. The testing results in both situations were quite positive, demonstrating the advantages of deploying robot platforms as a support tool. Assistance provided to senior citizens is more tailored and suitable, enhancing their independence, well-being, and quality of life [28]. Figure 4: Literature review tree. Studies show that it is possible to employ technology in a way that enhances the quality of life of older people. The demand for IoT devices with advanced capabilities to perform more complex activities for elderly people is profound. Recently, the concept of smart homes has garnered significant attention from various sectors, including researchers, industry professionals, and academia. Smart home environments can be controlled through any smart gadget. Wireless communication methods are utilized to monitor and manage household functions through smartphone applications. Cloud computing provides scalable processing power, storage capacity, and applications for developing, managing, and administering home services. It also enables access to home devices from any location at any time. In order to achieve aging in place, a sophisticated modification strategy and a flexible living environment are required to meet the desires of elderly individuals and maximize the effectiveness of smart technology [14]. Cloud computing brings a virtual platform, where all resources, whether software, hardware, or data, can be easily shared among stakeholders with minimal effort. The integration of IoT and cloud computing will significantly change how people live their lives, particularly in terms of information handling.
