Visualization systems often require large monitors or projection screens to display complex information. Even very sophisticated systems that exhibit complex user interfaces do usually not exploit advanced input and output devices. One of the reasons ...

This paper documents MultiKit: a toolkit that supports the development of sophisticated user-interfaces for applications using Near Field Communication (NFC). The usage of the toolkit is exemplified using three implemented prototypes, each with ...

With the advent of mobile devices with large displays, it is intuitive and natural for users to interact with an application on a mobile device using multi-touch gestures. In this paper, we propose that these multi-touch gestures can be streamed on-the-...

Today, one does not have to travel far to find examples of digital signage, yet the adoption of interactive gesture based public displays remains quite rare. Subsequently, not much is known about them despite a large array of potential advantages. This ...

The "iShake" system uses smartphones as seismic sensors to measure and deliver ground motion intensity parameters produced by earthquakes more rapidly and accurately than currently possible. Shaking table tests followed by field trial with approximately ...

Some mobile devices automatically fetch content from social networking services and integrate it into the device user interface. In this paper, we explore how people consume integrated social networking services in a field study with an innovative ...

With the advantage of high bandwidth and low cost, WLAN is widely regarded as an appealing technology for wireless access. However, WLAN only provides very limited coverage which is no more than hundreds of meters, making users experience intermittent ...

"There's An App For That" -- but how do we actually develop them? While smartphones and tablet PCs are getting more and more popular and their application scenarios are growing, we still develop them using only a standard integrated development ...

In past years, ubiquitous computing technologies have been successfully deployed for supporting children with special needs. One focus of current research has been on post-hoc behavior analysis based on video footage where one or multiple cameras were ...

Mobility exists in many shapes; when migrating a running application (code, states and data) from one device to another, one has achieved application mobility. In this article we combine this mobility type with context awareness, defining context ...

This paper studies the idea of selecting music by exploring preview clips in an album cover space. In the implemented prototype, the user listens to representative audio clips until the preferred musical style has been found, and the corresponding song ...

Nowadays, urban traffic congestion has become a global phenomenon, resulting in a lot of negative effects both on economy and ecology. Thus, the detection of road congestion in cities is a highly urgent problem to be solved by scientists throughout the ...

A compelling video summarization should allow viewers to understand the summary content and recover the original plot correctly. To this end, we materialize the abstract elements that are cognitively informative for viewers as concepts. They implicitly ...

Technology-mediated communication including mobile phone and video conferencing on PC enable increasing bandwidth for everyday interactions between remote people. The effectiveness and social presence with traditional video conferences have been studied ...

Unlike most of the existing studies on video streaming over WLANs, which usually focus on only one type of video streams, either stored videos or live videos, in this paper we propose a dynamic scheduling method for transmitting a mixture of live and ...

The growing popularity of location-based services for mobile smartphones requires web content to be assigned with location tags. In this paper we propose a simple yet powerful approach that assigns location information tags to online content that hasn't ...

The co-evolution of social relationships and individual behavior in time and space has important implications, but is poorly understood because of the difficulty closely tracking the everyday life of a complete community. We offer evidence that ...

Variational methods are among the most accurate techniques of optical flow computation. TV-L¹ optical flow, which is based on L¹-norm data fidelity term and total variation (TV) regularization term, preserves discontinuities in the flow field and also ...

For resource-constrained wireless scenarios, this paper proposes a cooperative cross-layer scheme to improve the performance of scalable video transmission. At the application layer, the extraction parameters of scalable video coding are first optimized ...

The layered protocol architecture lacks of flexibility to support granular QoS requirements for multi-hop mobile wireless networks with limited bandwidth. Meanwhile, research indicates that TCP behaves inefficiently in such networks. Recently ...

In this paper, we present a 3D indoor navigation service system based on smartphones. To achieve an accurate indoor navigation system in a multi-storey building, it is necessary to determine the storey where the user is. By attaching an atmosphere ...

Traditional public notice areas (PNAs) are nowadays a popular means to publicly exchange information and reach people of a local community. The high usability led to a wide-spread use in stores, cafes, supermarkets, and public institutions. With public ...

Public displays are becoming a ubiquitous resource in the urban environments due to significant price drops of large LCD panels. However, most public displays are still displaying simple advertisements in the form of slide shows or movie clips, instead ...

This paper presents the methodology and outcomes of the Collective City Memory of Oulu study that we conducted in order to research whether it is feasible to embed community shared memories in the physical landscape of a city exploiting deployed public ...

Authorities recommend the practice of moderate physical activity to improve health and quality of life, but sometimes it is difficult to find the willpower or the motivation to reserve a few minutes to exercise. In this paper we describe a new tool ...

This paper introduces the UBI Challenge that challenged the global R&D community to design, implement, deploy and evaluate novel applications and services in real world setting atop an open urban computing testbed. The paper first provides a procedural ...

Video adaptation has been considered as a promising technique to bridge the gap between network status, device capabilities and user preferences in pervasive media applications. However, conventional adaptation framework based on transcoding or multiple ...

Recent years we have witnessed the rapid advent of mobile cloud computing, in which remote software is delivered as a service and accessed by mobile device users over the Internet. However, most existing remote display technologies for high motion ...

Mobile video broadcasting is a popular application of wireless network. However, the traditional layer based approaches have limited supports to the accommodation of users with diverse channel conditions. The newly emerged Softcast approach provides ...
