The user participatory design resulted in valuable input from persons with dementia, informal carers and professional carers/dementia experts, based on which a first prototype Rosetta system was built.
All participants found Rosetta a very useful development for future care, and would consider using it. Since Rosetta was still in development during evaluation, a discrepancy between expectations and actual functioning of Rosetta existed, which may explain the lack of findings on the impact of the system and the low appreciation of user-friendliness. Implications for Rehabilitation People with dementia and carers find assistive technology (AT) a useful future development and they are willing to use it in the future. People with dementia and carers have little privacy issues with AT. If they have concerns, they are willing to accept the trade-off of reduced privacy in exchange for the ability to live in their own homes for longer. Given that a system works flawlessly, informal carers indicate that integrated AT can reduce their burden and stress. This can in turn help informal carers to provide better care for a longer period of time.
In this paper we present a web services-based platform that facilitates and speeds up the development and deployment of context-aware, integrated mobile speech and data applications. The platform is capable of handling different types of context and offers sophisticated personalization mechanisms. To illustrate the usefulness of the platform and to validate the claim that cross-platform application development, in particular mobile, context-aware applications, is easier and faster with web services technologies, we present a demonstration application. It serves tourists with interesting information and services in their specific context, and contributes to the achievement of their current goals. Finally, we present a number of problems that we experienced in the implementation process as well as the feedback that we received from real users who tested our application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
