Mobile health (mHealth) innovations are considered by governments as game changers toward more sustainable health systems. The existing literature focuses on the clinical aspects of mHealth but lacks an integrated framework on its sustainability. The foundational idea for this paper is to include disciplinary complementarities into a multi-dimensional vision to evaluate the non-clinical aspects of mHealth innovations. We performed a targeted literature review to find how the sustainability of mHealth innovations was appraised in each discipline. We found that each discipline considers a different outcome of interest and adopts different time horizons and perspectives for the evaluation. This article reflects on how the sustainability of mHealth innovation can be assessed at both the level of the device itself as well as the level of the health system. We identify some of the challenges ahead of researchers working on mobile health innovations in contributing to shaping a more sustainable health system.

We propose a process reference model for UX (UXPRM), which includes a description of the primary UX lifecycle processes within a UX lifecycle and a set of supporting UX methods. The primary UX lifecycle processes are refined into objectives, outcomes and base practices. The supporting UX methods are refined into related techniques, specific objectives and references to the related documentation available in the literature. The contribution of the proposed UXPRM is three-fold: conceptual, as it draws an accurate picture of the UX base practices; practical, as it is intended for both researchers and practitioners and customizable for different organizational settings; methodological, as it supports researchers and practitioners to make informed decisions while selecting UX methods and techniques. This is a first step towards the strategic planning of UX activities.

This paper presents the Keep-In-Touch project, which aims at developing an integrated Ambient Assisted Living (AAL) solution assisting and monitoring elderly people in their daily-life activities, supporting personal autonomy and well-being, and maintaining social cohesion. The focus of this paper is the integration of interactive user modeling, the benefit of the combination of user-centered development method and fast prototyping implementation in order to develop a solution which fits the end-user. The key elements to achieve this goal are: multimodality, accessibility, adaptability to user profile and changes, and usability. We will show how our approach addresses these needs.
