Exploring Digital Image Frames for Lifestyle Intervention to Improve Well-being of Older Adults

This contribution addresses the development of technology for senior users with the aim to improve their general wellbeing. We present a prototype system named CARE that is used for in-situ testing in a seniors home and combines functionality of a digital image frame with an active recommender mode. The purpose of the recommender is to provide the user with context-specific recommendations. Recommendations are chosen on the basis of sensor data and a well-being model to carefully decide on at which point in time what kind of activity will be most suitable to suggest.

Providing Life-Style-Intervention to Improve Well-Being of Elderly People

We report on a user-centered approach towards the development of an augmented digital picture frame - called “CARE” - for senior users with the aim to improve their general well-being. The central idea is to interleave the display of pictures with the provision of recommendations of activities that seniors may perform in addition to their ordinary daily routines. We also report on our attempt to encourage durable use of the CARE system by introducing reward schemes for recommended activities. Feedback from users suggests that reward schemes should be made individually configurable.

Theodor: A Step Towards Smart Home Applications with Electronic Noses

This paper presents preliminary results of the ongoing project TheOdor which explores the potential of electronic noses that make use of commodity gas sensors (MOS, MEMS) for applications in the smarthome, for example, to classify human activities based on the odors generated by activities. We describe the system and its components and report on classification results from first validation experiments.

Exploring Opportunistic Ambient Notifications in the Smart Home to Enhance Quality of Live

Smart home technology became more and more widespread within recent years. They aim to make life easier and taking over unwanted tasks. In traditional homes, it is often not clear whether all windows and doors of a house are closed before inhabitants leave the home or go to sleep. However, this can be easily addressed by smart homes. We present a system based on opportunistically located ambient lights that assist inhabitants of a smart home in answering this question. In this paper, we show the concept of our system and the inhabitant-centered design process behind the development. The system was installed in a one-family smart home. We report on insights gained through data collected from this deployment over a period of six months. Within interviews, we found that the ambient light system gave inhabitants a more confident feeling about open doors/windows.

Towards a Gamified Recommender System for the Elderly

Starting from our previous work on a digital picture frame - the CARE system - that interleaves a picture display mode with a recommender mode to promote a healthy life-style and to increase well-being of elderly people, this paper investigates the use of gamification as a means to increase user appreciation of the CARE system. To this end, we arranged two co-design workshops with peer-groups of senior citizens. We report on outcomes of the workshops and draw conclusions for a gamified version of CARE.

Development of a Multi-Device Nutrition Logging Prototype Including a Smartscale

In this work we present a portable system for nutrition logging that integrates multiple devices and modalities in order to facilitate food and drink tracking. The system consists of a smartphone, a smartwatch and a smartscale that can be combined flexibly by users depending on the current situation and their personal needs. Based on a requirement analysis, we present the rationale behind the design and implementation of our food and drink logger. We also report the preliminary results of an in-situ study we conducted in order to explore the potential benefits and challenges of a multi-device approach to nutrition tracking in daily life settings.
