Within the areas of distributed, off-grid, and decentralized energy, there is a growing interest in local energy exchanges. A crucial component of an energy exchange is a return provided by an energy-receiver to an energy-giver for the energy provided. The existing energy literature on such returns is primarily limited to monetary returns and...

The energy and building research community acknowledges the importance of including occupants' wellbeing in the evaluation of building energy performance. Particularly in office buildings, occupants' comfort assessment is not yet a common practice, partially due to the shortcomings of the comfort assessment activities. Contextual factors such as...

Shorter hospitalisation is a strategy that healthcare services have adopted to solve the problem of high demand for hospitalisation under conditions of insufficient resources. Early discharge demands patients to self-manage their recovery at home, while recovery is still perceived a clinician’s responsibility. This often results in an extra...

Many energy researchers and practitioners envision householders to have an active role in local energy distribution in emerging energy systems. In the energy literature, the dominant view of local energy distribution, grounded in the rational choice perspective, sees exchanges of energy between households as energy trading. The existing...

Local generation, distribution and consumption of renewable energy within neighborhood is an emerging application context for the concept of `sharing'. This position paper introduces a cross-cultural approach to enable `new' social practices of renewable energy sharing in neighborhoods. The approach is being developed based on ongoing field...

In the near future, human-like social robots will become indispensable for providing support in various social tasks, in particular for healthcare (e.g., assistance, coaching). The perception of realism, in particular human-like features, can help facilitate mediated social interaction. The current study investigated the effects of form realism...

With the advent of Smart Energy Systems and Energy Cooperatives in the Netherlands and elsewhere, sharing of renewable energy within neighbourhoods is likely to gain wide prominence in the near future. Today the concept of 'Energy Sharing' is often limited to householders 'selling' their surplus of locally generated energy to the energy grid....

Data collection and reflection are considered an integrated process in Personal Informatics to help users take action towards changing behaviour. Facilitating the collection and visualization of large data sets has been a major technical challenge to guarantee meaningful and effortless information to users. However this focus results in a...

In this paper we present preliminary outcomes concerning the design of a support system for midwives in the Netherlands to carry out daily activities. The purpose of our design is to make the workflow of midwives more efficient. Our user studies confirm that the current workflows of midwives to support pregnant women lack efficiency. The most...

In this paper we describe the design of a home energy and comfort management system. The system has three components such as a smart plug with a wireless module, a residential gateway and a mobile app. The combined system is called a home energy management and comfort toolkit. The design is inspired with the fact that making energy visible and...

In this paper we present our approach for informing the design of ubiquitous computing by using pattern languages of human practice. By linking ethnography and design, this approach makes it possible to tackle the social dimension of ubiquitous computing in the design processes. Adding to the existing research on patterns of human practice for...

Sometimes, the way in which we interact with products implicitly communicates how we feel. Based on previous studies on how emotions can be detected and communicated via product interaction, we discuss how an interactive product could influence affect by responding and changing behaviors expressing affect. We discuss the proposal of the...

This paper presents a study about a ‘serious game’, “Energy Battle”, as a means to influence energy-related behavior in households. The Energy Battle is designed to engage home occupants in a fun way in energy conservation via a competition with other households. The challenge enabled home occupants to gain insight in their energy consumption...

Recent field experiments on acceptability of notifications in the home showed that people generally want to be informed of urgent messages as soon as possible, whereas non-urgent messages should not be presented at all. A possible way to improve the acceptability of a notification might be to adjust the presentation mode and the timing of...

A recent focus is on creating engaging user experiences with digital products and services such as voicemail. This study aims to design towards increased levels of engagement in voicemail browsing by using the ‘Richness, Control and Engagement’ (RC & E) framework. This framework explains the levels of engagement in terms of the levels of...

A field study in ten homes was conducted to understand what influences users’ acceptability of notifications in the home environment. The key finding is that perceived message urgency is the primary indicator of acceptability of notifications in the home—if people think a message is urgent, they want the message to be shown immediately,...

The complex control problem of creating home atmospheres using light, music, and projected wall-art can be reduced by focusing on desired expe- rience, rather than product functions and features. A case study is described in which subjective interpreta- tions of living room atmospheres were measured and embedded into a prototype display system....
