The advancement of ubiquitous computing technologies has greatly improved the availability of digital resources in the real world. Here, the authors investigate mobile interaction with tagged, everyday objects and associated information that's based on the Internet of things and its technologies. Their framework for integrating Web services and mobile(More)
Although mobile services can be used ubiquitously, their employment and the interaction with them are still restricted by the constraints of mobile devices. In order to facilitate and leverage mobile interaction with services, we present a generic framework that combines semantic Web service technology and physical mobile interaction. This interaction(More)
Mobile devices are more and more used for mobile interactions with things, places and people in the real world. However, so far no studies have discussed which interaction techniques are preferred by users in different contexts. This paper presents an experimental comparison of four different physical mobile interaction techniques: touching, pointing,(More)
Mobile interaction with objects from the real world is gaining in popularity and importance as different mobile technologies increasingly provide the basis for the extraction and usage of information from physical objects. So far, Physical Mobile Interaction is used in rather simple ways. This paper presents a comparison and evaluation of more complex and(More)
The advancement of Ubicomp technologies leverages mobile interaction with physical objects and facilitates ubiquitous access to information and services. This provides new opportunities for mobile interaction with the real world, but also creates new challenges regarding the complexity of mobile applications, their interaction design and usability. In order(More)
In current authoring tools for location-aware applications the designer typically places trigger zones onto a map of the target environment and associates these with events and media assets. However, studies of deployed experiences have shown that the characteristics of the usually invisible ubiquitous computing infrastructure, especially limited coverage(More)
The interaction between mobile devices and physical objects in the real world is gaining more and more attention as it provides a natural and intuitive way to request services associated with real world objects. We currently see several approaches for the provision of such services. Most of them are proprietary, designed for a special application area or(More)
Near Field Communication (NFC) is a technology for mobile, touch-based interaction with tagged objects that can serve as physical user interfaces (UI). Dynamic NFC-displays use a grid of NFC-tags as a physical UI and combine it with a projected application UI to enable direct interactions between mobile devices and large screens. In this paper, we explore(More)
Mobile interactions with the real world, meaning a person using her mobile device as a mediator for the interaction with smart objects, is becoming more and more popular in industry and academia. Typical technologies supporting this kind of interactions are Radio Frequency Identification (RFID), Near Field Communication (NFC), visual marker recognition, or(More)
