The project aims at integrating miniaturised physiological sensors into hearing glasses device with ambient sensors in order to gather ambient and physiological data and transform them into relevant information through the implementation of specific algorithms. This information will be used for providing customised services to the end-users in order to improve the quality of their daily life, for tele-recalibration of hearing devices as well monitoring physical conditions. To achieve the best results within the AHEAD project, end-users will be involved in the development process right from the beginning to guarantee a maximum usability, perceived usefulness, acceptance and accessibility of the proposed AHEAD system. The consortium is ensuring their involvement from the very beginning of the project based on the user-centred design approach (UCD). End-user involvement in the pilots allows us to assess the benefit of the proposed solution.
