Design for Youth's Flourishing: Intervention design strategies to enhance teenagers’ mental resilience and well-being

The urge to promote mental health and well-being is gaining increasing importance and attention in recent years. Adolescents, who are among the most vulnerable under this aspect, are experiencing an increase in mental health complaints and need of youth care in the Netherlands. In addition, they perceive current means of care as inappropriate to...

Repairable smartphones: Developing a Product-Service System that stimulates consumers to choose for repair over replacement

The increasing global need for environmental preservation calls for new methods to increase the material efficiency of products. One way to do this, is by extending the use cycle of a product, by making the product more repairable. This thesis has studied existing use cycle extension strategies to propose a new smartphone ProductService System...

Comfort and discomfort during smartphone use on a bed

BACKGROUND: The number of smartphone users is immense. People can do ever more with a smartphone. Smartphones are used everywhere, including in bed and on the sofa. The awkward postures taken in these situations affect comfort and discomfort. In designing a bed, it might be useful to know which position is comfortable for smartphone use on a...

Indoor Localization through Pedestrian Dead Reckoning and Activity Recognition: A smartphone-based proof of concept

Pedestrian indoor localization is a problem yet to have a solution that is as generally accepted as the Global Positioning System is for outdoor localization. An infrastructure-independent option is to leverage the data from Inertial Measurement Unit (IMU) sensors to determine position. An advantage of this approach is that these sensors are...

An auditory dataset of passing vehicles recorded with a smartphone

The increase of smartphones over the past decade has contributed to distraction in traffic. However, smartphones could potentially be turned into an advantage by being able to detect whether a motorized vehicle is passing the smartphone user (e.g., a pedestrian or cyclist). Herein, we present a dataset of audio recordings of passing vehicles,...

Smartphone controlled home environments

This master thesis “Smartphone controlled home environments” aimed the integration of gesture control in the context of Smart living. Gesture control as one of the Natural User Interface, shows a limited usage, by mainly being used in the entertainment industry. The property of gesture control was seen to be potential to contribute to smart...

Domestication of smartphones and mobile applications: A quantitative mixed-method study

Smartphones are finding their way into our daily lives. This paper examines the domestication of smartphones by looking at how the way we use mobile applications affects our everyday routines. Data is collected through an innovative quantitative mixed-method approach, combining log data from smartphones and survey (perception) data. We find that...

Design a total concept that integrates online and offline retailing for Pets Place

Pets Place is the largest pet retail chain in the Netherlands. It is a franchor with about 170 stores in the Netherlands. Apart from the physical stores, Pets Place also has a website containing a webhop, the online store. More and more products are bought online at the expense of the physical retailers. The internet can be seen as a threat, but...

Automatic registration of iPhone images to laser point clouds of urban structures using shape features

Fusion of 3D airborne laser (LIDAR) data and terrestrial optical imagery can be applied in 3D urban modeling and model up-dating. The most challenging aspect of the fusion procedure is registering the terrestrial optical images on the LIDAR point clouds. In this article, we propose an approach for registering these two different data from...

Batch Scheduling for Energy-Efficient Sensing in Smartphones

Sensing in smartphones consumes a significant amount of energy and leads to quick depletion of the battery. Most of the existing solutions to overcome the short battery lifetime caused by periodic sensing are personalized. They tend to learn and predict the user activities. Thus, fewer samples are required to recognize user state and sensing...

Offline Trace Synchronization for Smartphone Energy Profiling

Energy profiling is a means to effectively understand the power behavior of smartphone applications. However, no tool that effectively combines portability, accuracy and automation has been proposed yet. In this thesis a new approach is proposed, which sets the basis for such a tool by solving a trace synchronization problem. TRAce Merger uses...

Design for Enhancing the Efteling Experience for Deaf and Hard of Hearing People

The Efteling has been welcoming and entertaining its visitors since the opening of the Sprookjesbos in 1952. The Efteling is accessible for every guest. It offers special facilities for wheelchair-dependent people, but people with hearing loss are not supported by any facilities. The company is advised to tackle this problem early on, because...
