The eHome project was started in order to find out how a smart home would perform under normal everyday conditions. A network of ubiquitous devices and user interfaces were installed in a regular 52 m apartment, where two young people lived and used the equipment in their everyday lives. The goal was to study what a smart space should contain and how users(More)
Aging people are in risk of social isolation due to direct or indirect effects of aging. Social isolation decreases the quality of life, health and acts against independent living, which is important for both the elderly people and society. Social networking can provide elders a sense of presence with their relatives, friends and healthcare personnel which(More)
In smart homes, unobtrusive monitoring of user position and activity are important but challenging tasks. With the current state of technology, this task is especially hard to carry out in private areas where video surveillance is considered undesirable or even offensive. Even though some alternative methods for passive and unobtrusive monitoring of people(More)
In pervasive context recognition and user identification applications, unobtrusive recognition of user height and posture is difficult. With the current state of technology, this becomes even harder in environments where cameras are not desired or allowed. This paper answers this problem by presenting a simple, unobtrusive, and low-cost system for measuring(More)
Aging people are in risk of social isolation due to direct or indirect effects of ageing. Social isolation decreases the quality of life, affects health and acts against independent living, which is important for both the elderly and the society. Social networking can provide elderly a sense of presence with their "safety-net", that is, relatives, friends(More)
Speech is a natural form of interaction for people, and smart environments offer good possibilities for experimenting with new kinds of interaction with users and devices. Speech control can offer more intuitive and easy forms of interaction with the environment compared to traditional graphical or physical user interfaces. This paper describes the(More)
As user interfaces are becoming more ubiquitous and abundant, users may feel perplexed by the pure number of user interfaces surrounding them. In order to increase user acceptance, ubiquitous user interfaces should be designed to be as calm and nonintrusive as possible. This paper presents the design and evaluation of a calm user interface prototype, Living(More)
The BluePost is an enhanced car heating post, an electrical distribution box used for heating car engines during cold weather. We saw a need for enhancement of current models, since the design has been relatively unchanged for decades and the user interface is somewhat restricted to simple mechanical on/off control. The BluePost provides additional(More)
