## 4 Acceptance of New Gerontechnologies for Assisted Living  
The technology acceptability models, selected to be compatible with applications for older people to accept and use a technology, starts with the very classical TAM model [73]. TAM explains the user'sbehavior when using ICT can be used to understand the usefulness of technology via the attitudes of the use. The usefulness of TAM comes from understanding users' adoption and use of emerging technologies, which is predicated by the person's perceptions of the benefit from using the technology the and ease of use. A model depicting various gerontechnology usage factors discussed in [74], including those of multi stakeholder collaboration in older people communities [75] is illustrated in Figure 5.  
Judging from a literature reviewed (e.g., see [76]), we can establish that the acceptance of the IoT based gerontechnology within older people users is largely dependent on the following elements. First, the older people users must already have some motivation (as cognitive state and physical condition often are the limiting interaction factors) and perception of the added value. Motivation greatly influences the extent to which older people use their experiential and deliberative skills to make the technology-related decisions [77]. However, motivation often has a personal dimension, i.e., unless the tasks are personally relevant, older people will tend to minimize their cognitive effort. Today, motivation often comes from the social perspective, starting from easy communication with relatives and grandchildren, social network features, social, online, entertaining content and finishing with health-related telecare solutions. In the 21 st century, the elderly population often bravely start experimenting with and embracing the new (although sometimes only for themselves) technology. Depending on the facilitating conditions

Social networks and virtual communities can help older people to support an interest and a positive feedback among the older AAL users as well as to bridge the digital divide between older people and the younger generations [78]. Therefore, the proposed model envisions a possible feedback gathered from the rejected technology solutions. Considering the active aging paradigm, it is essential to develop and implement new strategies and technologies, even if typical barriers, such as lack of experience (or even fear) of modern technology in general, and the gerontology self-efficacy and anxiety, in addition to age and cognitive abilities. In this regard, we can hypothesize that a familiar environment, like a home of the elderly user, can become intelligent and provide various forms of monitoring, from localization and fall detection to non-intrusive healthcare, services, which are vital for our target audiences. Current technology allows customization to the user preferences and takes less strain on environment (smart systems lead to less consumption). The acceptance model is based on the claim, that IoT can serve as smart eyes, ears and hands assisting our elderly person and capable of providing necessary and needed health at appropriate times and situations. The main facilitating factors can be distinguished like the ease of use, as well as general user familiarity with technology (including fear of technology), possible improvement of care service (very important in digitized e-health services), low technical demands and an option to personalize to each elderly person as often the disabilities (if exists) varies, in addition to living, cultural, economic and environmental factors.
