Along with the emergence of health smart home services for elderly people, it becomes crucial to study their energy consumption in order to minimize it. This paper presents a framework, as “a structured way of understanding health smart home services.” Four aspects of the framework are identified--“human-computer interaction, cognitive and physical ability of users, domestic [home] setting [...], and smart technologies” that capture the settings of health smart home services--each of which is further categorized, together with individual elements identified for studying its implications--for example, service effectiveness--for health smart home services.

An energy consumption awareness system that incorporates mobile augmented reality (MAR) was introduced and a simulation was conducted using electrical devices with meters that monitor energy consumption. The results suggest that MAR could provide more intuitive and multimodal interaction.
