Solar Rays | © Wouter van den HoogenThis research project, part of the Sound Lighting theme, focuses on beneficial effects of (natural) light for human functioning and wellbeing. It builds on earlier research reporting beneficial effects of windows and sunlight on mental wellbeing (stress relief, decreased depression),  and research reporting activating and alertness inducing effects of artificial lighting. We investigate such effects and the underlying mechanisms, on the one hand by studying the independent contribution of (natural) light, weather and a view to the outside, on the other hand by studying the independent contribution of characteristics of artificial lighting (e.g., illuminance, colour temperature) on human functioning. The project entails experimental research, aiming to measure effects of light on vitality, stress, alertness and performance and to investigate personal preferences as a function of time of day and mental status. In addition, it encompasses surveys, field studies, and experience sampling methodologies to capture light’s relevance in real life.

Knowledgeable Service Robots for Aging (KSERA)

Project Leader: Raymond Cuijpers
Researchers: Raymond Cuijpers, Lydia Meesters, Jim Juola, Elena Torta and David van der Pol

NAO robot interaction | © Wouter van den HoogenBy 2050 37% of the EU population will be over 60 years of age and it is expected that there will be fewer than two persons of working age per elderly person of 65 or older. This will lead to both an increasing demand for care and a shortage of care‐givers. Elderly people need support due to their declining capabilities but also to age‐related illnesses such as Chronic Obstructive Pulmonary Decease (COPD). COPD typically manifests itself at a later age (from 40 years on). According to the World Health Organisation (WHO) COPD will be the third major cause of death in 2030. Intelligent home environments are one of the key facets to counterbalance the reduced number of caretakers and increase the QoL of elderly.

In the KSERA project the aim is to seamlessly integrate smart home technology with socially assistive robots. The main research question addressed in this project is how to obtain a successful, effective interaction between the human and the mobile robot (http://www.aldebaran-robotics.com) to guarantee acceptance and adoption of service robotics technology and offer added value of the ubiquitous monitoring services.

Sound Lighting – sustainable light application for human health and performance

Project Leaders: Yvonne de Kort, Cees Midden
Researchers: Femke Beute, Antal Haans, Jaap Ham, Yvonne de Kort, Daniel Lakens, Cees Midden, Karin Smolders

Sound lighting is the name of one of the four program lines in the interdepartmental Intelligent Lighting Institute, focused on the sustainable application of light for human health and performance. It encompasses a multidisciplinary range of research projects, fundamental and applied. Human-Technology Interaction is managing this program line and is responsible for a substantial part of the research performed under this theme. For HTI this research centres on psychological mechanisms through which light – natural or artificial, coloured or white – impacts human affect, cognition, and behaviour. For instance, such mechanisms could be associative, evaluative, or related to individuals’ beliefs regarding light and health. The research adopts an integrative approach to light research by examining these psychological mechanisms, their interplay with biological processes, and the individual differences and contexts in which light impacts mood, cognitive performance, restoration, stress and sleep quality.

Sustainability and behavior by means of human-technology interaction

Project leader: Cees Midden
Researchers: Cees Midden, Ron Broeders, Jaap Ham

The goal of the project is to make people's behavior more sustainable toward their environment. Part of this project is focused on reducing littering behavior. Based on social-psychological theories behavioral interventions regarding littering in public places are designed. At the core of our ideas is the belief that littering behavior also can be a result of an automatic instead of a deliberate process. Recent observations have shown that people often are unaware of their behavior when they litter. The ultimate aim of the project is to develop several interventions that clasp on this personal unawareness regarding littering behavior, thereby persuading individuals in an unconscious manner to bin their garbage. The main challenge of the research is developing fundamental theoretical social psychological insights, by means of lab experiments, and translating this knowledge to applications in the field. The project is conducted in cooperation with "Stichting Nederland Schoon" and the City Council of Eindhoven.

Persuasive Agents: Persuading the members of a household to save energy.

Project Leader: Cees Midden
Researchers: Jaap Ham, Peter Ruijten, Maaike Roubroeks

This research project, part of a larger project in which teams of psychologists (Eindhoven) and computer scientists (Tilburg) collaborate with Smart Homes, the Dutch Expertise Centre on Home Automation & Smart Living, is designed to develop novel techniques for persuading members of households to conserve energy. Specifically, the aim is to develop personalized agents in the form of avatars or robotic interfaces that provide feedback and suggestions in an attractive and non-disturbing way (i.e. not interfering with daily activities).
From a theoretical point of view, psychology and technology are combined to form an effective and efficient way of developing the persuasive agents, and this will be tested through experimental research. From a more practical viewpoint the to-be-developed techniques will be tested in a realistic environment to test whether techniques keep their persuasive power in practice. In the department of Human-Technology Interaction, theories are tested by means of empirical experiments. Our topics of interest in this project are to optimize the user-agent interaction and to set up persuasive interventions to convince people to conserve energy in their households.

Perception of Haptic Feedback in Telesurgery

Project leader: Dik Hermes
Researchers: Don Bouwhuis, Dik Hermes, Wijnand IJsselsteijn, Koen Crommentuijn

At the Department of Mechanical Engineering at Eindhoven University of Technology a new system for teleoperated surgery is being developed. The HTI group carries out user studies to assist in the design of this system. With teleoperated surgery, or telesurgery for short, a surgeon sits behind a console from which he/she controls two robotic surgical instruments. Because of teleoperation, only small incisions are required and motion scaling and tremor filtering can be applied.

With current telesurgical systems, however, the sense of touch is lost. Surgeons do not experience the forces that occur when controlling the robotic instruments. Restoring force information is one of the main features of the teleoperation system being developed at the department of mechanical engineering. Forces encountered by the robotic instruments will be fed back to the surgeons through a haptic interface. Currently, only basic guidelines exist as to what specifications a teleoperation system must satisfy. An example of such a guideline is that haptic interface should have low internal friction. To what level friction should be reduced is however, unknown.

It is the goal of this project to identify system characteristics that affect the surgeons’ ability to accurately and comfortably perform telesurgery. User performance studies are carried out to determine optima for the identified system characteristics in order to provide designers and control engineers with specific guidelines for a telesurgical system.

MyMedia: Dynamic personalization of multimedia

Project Leader: Martijn Willemsen
Researchers: Martijn Willemsen, Dirk Bollen, Lydia Meesters, Bart Knijnenburg

MyMediaWe are drowning in a sea of information overload. Television channels, books and music assault our senses with far too much content. How do you find content that matters to you? How do you discover multimedia information and entertainment in a way that suits you personally? Isn’t there an easier way? MyMedia recommendations will help solve this “crisis of choice”. The MyMedia project seeks to advance the state of the art in several areas including creating a software framework for building recommender systems, creating a protocol for plugging in multiple content catalogs, and pluggable recommender algorithms that can be targeted at specific needs. The project will work on new algorithms, new ways to model user preferences, provide the ability to incorporate aspects of social networking to create media centric communities, and research enhancements in the use of metadata for recommender systems. The researchers in Eindhoven focus mostly on psychological aspects underlying recommender systems, user preference modeling, and on a generic evaluation framework that is used to evaluate the recommender systems tested in the field trials.

Persuasive Technology, Allocation of Control, and Social Values

Project leader: Anthony Meijers
Researchers: Anthony Meijers, Andreas Spahn, Jilles Smids, Cees Midden, Jaap Ham, Frank Verberne, Maarten Steinbuch, Theo Hofman

Driving SimulatorModern-day technologies are capable of introducing intelligent automation in vehicles, ultimately leading to the possibility of a driverless vehicle. Such intelligent automation can have several advantages such as saving energy and increasing safety on the road. In this multidisciplinary project (covering psychology and philosophy), we investigate persuasive technology that encourages people to hand over control to intelligent automation. We investigate psychological factors that influence people’s willingness to hand over control to intelligent automation. Furthermore, we investigate philosophical aspects that play a role in handing over control to intelligent automation, such as the morality of persuading people to give up control and responsibility of accidents as a result of the use of automation. A driving simulator will be used to measure actual use of several intelligent automation technologies.

Dode hoek Detectie en Signalerings Systemen (DDSS): Concepten van signalering

Project Leader: Jaap Ham
Researchers: Dr. E.S. Wilschut, Ing. V. Meijering, B. Merkus, Dr. W. IJsselsteijn, Dr J. Ham

blind spotThis project investigates what kind of blind spot detection and signaling system (DDSS) provides the best way to signal the truck driver and/or the vulnerable road user, after detection of a dangerous situation. A lot is already known from the literature about human information processing of system signals, in which trust, acceptance and persuasive technologies play an important role. The main aim is to determine through theoretical research in which way the driver can be optimally informed and warned. Leading to the most adequate reaction and thereby preventing possible accidents. From literature about internal and external motivation it is known that when a system is less intervening to reach a behavioral change, better results are achieved on a long term. Therefore a DDSS should be intervening as little as possible in early stages e.g. only suggesting where possible bicycles are in the blindspot. But when the situation becomes more urgent and dangerous the DDSS should warn more strongly and act more directive.
