Virtual carers for the elderly: A case study review of ethical responsibilities

Intelligent digital healthcare systems are becoming an increasingly considered approach to facilitating continued support of our ageing population. Within the remit of such digital systems, 'Virtual Carer' is one of the more consistent terms that refers to an artificial system capable of providing various assistive living and communicative functionalities, embodied within a graphical avatar displayed on a screen. As part of the RITA (Responsive Interactive Advocate) project - a proof of concept for one such virtual carer system - a series of semi-structured discussions with various stakeholders was conducted. This paper presents the results of these discussions to highlight data security, replacement of human/physical care and always acting in the user's best interest. These three ethical concerns and designer responsibilities are identified as highly relevant to both individuals and groups that may, in the future, utilise a system like RITA either as a care receiver or provider. This paper also presents some initial, theoretical safeguard processes relevant to these key concerns.
