The number of older people in the EU (65 years and older) will increase to 149 million by 2050 compared to the current 101. A large percentage of this population has not followed the transition to the world of ICT. Even for application specially aimed at the elderly, the adoption is low. This suggests that despite numerous design guidelines published for designing interfaces for elderly, there is still work to be done. In this paper, we look at existing Technology Adoption Models, especially that of Lee et al. that focuses on elderly, and investigate whether current user interface design guidelines cover the adoption factors. For this, we did a literature survey on user interface design guidelines for elderly and found a rather heavy focus on the Usability factor while the others adoption factors were hardly covered. We propose to augment the set of existing user interface guidelines with guidelines that also support the other adoption facts of Lee. For this purpose, we present a first version of a reference model that could be used to organize guidelines, but also as a guide to uncover new ones.
