REACH considers integrated consideration of privacy, ethics, legal, and security aspects, as a key element to gain large-scale acceptance and market success of the solutions it has developed.
The REACH system incorporates two strands of technological elements; on the one hand, sensing and monitoring elements, and, on the other hand, motivational and physical engagement elements. For both types, user acceptance is critical allowing for a user experience that leads to (intrinsic, extrinsic, etc.) motivation to more physical activity. Acceptance and user experience in REACH are created by a coordinated interplay of a) high usability and convenient accessibility, b) accommodating need for privacy and autonomy, while counter-balancing this with the need for monitoring to secure the health and responsible care; and finally, c) personalized design for behavior change.
In addition, REACH has enlisted legal and ethical know-how and skills to analyze and formalize the implications of the use of various forms of machine learning and artificial intelligence in the context of providing care and health services to older persons.
REACH has made initial attempts to formalize its outcomes with regard to acceptability considerations in a REACH specific extensions of the unified theory of acceptance and use of technology (UTAUT).
