# A Helping Hand to the Elderly: Securing Their Freedom through the HAIE Framework
## 6 Results and Discussion
### Critical Analysis  
The analysis and assessment of various models referenced in the literature study demonstrate the efficacy of the HAIE model. The distinctions between the HAIE model and the other models referenced in the critical analysis are seen in Table 1. A total of five components are illustrated in Table 1.  
* Eliminates or minimizes: formal care, informal care, self-care. * Meets expectations: older person, family, formal/informal care. * Time of formal/informal care required: hourly, daily, weekly. * Cost: low, moderate, costly. * Cloud-enabled. The names of many models that were referenced in the literature review are listed in the \"Model\" column in Table 1. The \"Eliminates or minimizes\" column in Table 1 shows

The \"Met expectations\" column in Table 1 demonstrates the level of acceptance and belief in the model by the older person, their family, and caregivers. The \"Formal/Informal Care Required\" column illustrates when (and how much) formal/informal care is required for the older person who relies on the model. The \"Cost\" column in Table 1 illustrates how reasonably priced the model is. * Eliminates or minimizes: formal care, informal care, self-care
* Meets expectations: older person, family, formal/informal care. * Formal/informal care required: hourly, daily, weekly. * Cost: low, moderate, costly. * Cloud-enabled. The model proposed by HAS (2005) satisfies self-care and meets the expectations of older persons, but it requires hourly-based care at a high cost. The IoT-CHO (2015) model is also engaging, targeting older people who require daily care at a high cost. IoT-H2U (2016) adds self-care as an option to informal care, meeting the demands of elderly persons for high-quality care but at a high price. The proposed model HS-IoT (2017) satisfies self-care for older persons with formal/informal care at a low cost. In 2018, the ICE model with the same functionality as IoT-H2U but with a moderate cost was proposed. ICE (2018) focuses on meeting the expectations of the family. Along with ICE, the HAST (2018) model addresses the requirements of formal care, self-care, older persons, family, and daily care, at a reasonable price. The HAIE model reduces the older person's requirement for formal, informal, and self-care. For example, [PERSON]'s smartwatch reduces the need for formal care by regularly monitoring his vitals and sending reports to his doctor and daughter. Another example is [PERSON]'s smart voice assistant, which assists her in remembering daily tasks and reduces the need for informal care. The HAIE model effectively meets the needs of older individuals, their families, and caregivers. [PERSON]'s voice assistant has met her expectations by helping her remember things and live a more independent life. [PERSON], [PERSON]'s daughter, also had her expectations met as she received regular updates on her father's health through the smartwatch. Generally, an older person using the HAIE model requires formal care once a week and informal care once a day. For instance, [PERSON]'s smartwatch requires daily informal care for charging, and his vitals are sent to the doctor weekly for routine check-ups, requiring formal care once a week. The HAIE model incorporates devices with a range of affordable to moderately priced options. For instance, smartwatches are available at various price points in the market, ranging from INR 2000 to INR 6000.
