tice,dignity, trust andpatient safetyand rights” [38].Respecting the individual isoneof themainprincipleofperson-centred research [39].Therefore, the term“user” shouldbe avoidedwhen referring to theolderperson in thewelfare technologycontext. Person centredmeans “putting the person in the centre (not in themiddle) as a necessarycondition forproper careandgoodandefficienthealthcare services” [40] and “standardofcare that ensures thepatient/client is at thecentreofcaredelivery” [41]. Taking these concepts into consideration, it is here where technology researchers usually fail.Most technologyresearchersdonotconsiderwhat theolderpersonneedsor desires, even if that is the goal ofwelfare technology. Previousworks have pointed out that theend-user isusuallyforgottenbecausetechnologyresearchersfocusmerelyonthe technical aspects, thusneglecting theaimofhelping theuser in theirdaily life [11]. A reason for this could be that technology researchers do not always have the op- portunity to work directly with older people. On the other hand, some technology re- searchersmaynot look forward toworkdirectlywithpeople. Workingwithpeople isnotalwaysaneasy taskfor technologyresearchers.Usually, technical education does not involve how to approach people, especially older people. Inquiringaboutwhat theolderpeopleneeds are todevelopwelfare technologydoesnot imply just asking “what do you need?”. Instead, it takes a trained person in conduct- ing interviews to obtain the correct information needed. This is where the healthcare researcherscanhelp technology researchers. In addition, healthcare science focusingon thepersoncanmake sure theolder per- son’sneeds areplacedbefore theneedsof the researchers, industry, government, or any otherparty involved. Special attentionneeds tobepaid in the topicof learning thebehaviourof theolder person inasmarthouse.HBMcouldbe invasive inmanyways to theolderperson.Their privacy and space need to be respected. It is herewhere placing the older person in the centre is crucial toprovideadignifiedenvironment for theolderperson. Nevertheless, healthcare and technology researchersmay find difficulties to com- municatewith eachother. Technology researchers assumemany things thatmaybeun- knowntothehealthcareresearcher,andviceversa,whichmaygrowintofrustrationfrom bothsides. It should not be presumed that either the technical field ismore relevant than the healthcare fieldwhen developing awelfare technology.Both areas cannot be separated if thefinal goal is to improve the lives of older people.Therefore, there shouldbemore collaborationbetweenbothfields. 5.3. On theEthicsandLegalchallenges The ethical part is an important aspectwhen developingwelfare technology due to the severalchallengesthatarise.Thesechallengesrangefromcost-effectiveness,privacy,au- tonomy, informedconsent,dignity,safety,andtrust.Otherconcernsare the legalaspects, technology acceptance, exclusion, depression and isolation, the gap between designers andusers, and technology testingandassessment [10]. AtUSN, these ethical issues are considered inorder toprovidea safe anddignified environmentforolderpeople.However, technologyhaslimitationsandthuscannotsolve all theproblems related toageing [10]. The legal aspects are another essential part ofwelfare technology.Although coun- tries havedifferent laws involvingwelfare technology, the concerns tend tobe the same V.G.Sanchez /WelfareTechnology,Healthcare,andBehaviourModelling–AnAnalysis302
