The objective of this paper is to extend and apply the technology acceptance model (TAM) to connected healthcare technologies for the elderly. As far as the methodology is concerned, we distributed our survey by post. We targeted elderly people using connected health technologies (assistive alarm, telecare, sensors, etc.) at home and receiving health care at home. We received 213 questionnaires back. As we had several latent variables, we used partial least squares (PLS). The results show that the level of trust in these technologies impacts significantly the perception of usefulness and the degree of intrusiveness. In parallel, the degree of usefulness of these technologies impacts positively elderly people’s intention to accept their usage. Finally, one can claim that the perception of the social presence with the use of these technologies impacts positively the degree of perceived usefulness, trust, and intrusiveness.
