“…Program designers, especially those of young ages, are not likely to be familiar with these characteristics and needs of elderly users. This poses important limitations in the design of technology for this population because taking into account the mental model of individuals with MCI is crucial for the adequate design and testing of user-friendly ICT-based applications and services [ 56 ].…”

Background: Research has supported the cost-effectiveness of cognitive training tools enhanced by information and communication technologies (ICT) in several populations, including individuals with mild cognitive impairment (MCI) and age-related cognitive decline. The implementation of ICTs in this population, however, is sometimes challenging to their cognitive and age characteristics. Ultimately, this might compromise the effectiveness of ICT-enhanced therapies in this population. The aim of this study is to test the usability and acceptability of a European project prototype for elderly care, in an attempt to explore the ICT design needs of users with MCI. Methods: Participants were 28 individuals aged 58–95 years and with a diagnosis of MCI. Results: The results showed a low perception of peripheral elements and the need to place main interaction elements in the centre of the screen. The correlation between the general level of autonomy (daily life activities) and the ICT autonomy level was significant and positive. The speed of audio help had a significant impact on performance. Conclusion: The present work contributes to the literature on ICT usability needs of users with MCI. Some usability recommendations for designing interfaces for this type of user are provided in the text.

“…Therefore, it is crucial for technologies, like ehcoBUTLER, to be developed according to user's needs, abilities and interests. Likewise, helping older people to bridge the digital divide will bring greater integration and will benefit all society [24]. The purpose of this study is to assess the acceptability of ehcoBUTLER by means of a survey delivered to potential users and actors involved in their care, as essential part of its development in the European project.…”

EhcoBUTLER is an Information and Communication Technology (ICT) solution funded by the European Union (H2020; ID: 643566) and intended especially for elderly people with mild cognitive impairment (MCI) to improve their health, independence and quality of life, particularly at the social level. The purpose of this study is to assess the acceptability of ehcoBUTLER based on a survey delivered to potential users and actors involved in their care, exploring their expectations and preferences, while anticipating the system's functional requirements. The survey was delivered online to 313 participants (11% end users, 25% informal caregivers, 48% formal caregivers and 16% administration/management staff) from eight countries. Participants rated the different functionalities of ehcoBUTLER positively, 86.1% perceiving it as an interesting and useful system. Likewise, they assessed it as a commercially attractive product (75.1%). End users expressed a stronger preference for the social module. Nevertheless, they would be ready to pay a low monthly price for ehcoBUTLER. Professionals would be willing to pay choosing its functionalities modularly, but they would also expect it to be funded by the National Health System, centres or businesses. The conclusion is that all participants found ehcoBUTLER interesting, useful and ergonomic. However, to effectively implement it, it is necessary to bridge the digital gap and address the issue of insufficient investment in products aimed at older adults with cognitive impairment. To supplement cognitive training systems with social, emotional or entertainment functionalities could improve adherence to their use.

“…Personalization and users' self-customization design paradigms can be very useful within inclusive strategies that try to address the particular needs of users with disabilities (Hendricks, 2007;Wagner et al, 2010;García-Betances et al, 2016). Many serious design challenges are related to usability issues arising from users' physical, cognitive and behavior functional limitations, and reduced abilities in general, which can significantly affect user acceptance and adherence (Eberle et al, 2011;LeRouge et al, 2013;Schraepen et al, 2017;da Costa et al, 2018).…”

_______________________________________________________________________________________________________Design of computer-based non-pharmacological cognitive healthcare interventions for people afflicted by chronic neurodegenerative impairments must be soundly informed by and clearly centered on users' distinctive disabilities. In this article we present a use-oriented analysis of those cognitive interventions intended for healthcare of patients with Alzheimer's dementia and related disorders that use human-computer interaction based on virtual reality technology. The analysis identifies the most important strengths and weakness, and describes and assesses the main key opportunities and challenges inherent to the use of this type of cognitive healthcare interventions. The most critical specific usability concerns that considerably affect these interventions are described in order to be directly addressed during a user-centered design process. Significant evaluation issues that still trouble these interventions' general acceptance are also included. On the basis of this analysis, appropriate actions are recommended to help minimize accessibility and usability issues. Finally, concrete design guidelines, and a framework with its road map are proposed to direct the design process. The proposed framework's more outstanding features and functionalities are described in relation to user-centered design conceptualization, implementation and assessment. The use of a consistent usercentered design methodology, such as the one proposed here to tackle the main critical obstacles, could turn out to become the key that allows to achieve a substantial improvement of VR-based cognitive healthcare interventions effectiveness. _____________________________________________________________________________________________________ Keywords: Computerized cognitive healthcare, Virtual reality for healthcare, Non-pharmacological cognitive healthcare, Alzheimer's dementia.
