The embrace of pervasive devices accounts for the production of a massive amount of location data. While multitudes of algorithms have been used for location clustering, most of them focus on the proximity clustering of locations rather than on their ...

We present a framework for large-scale crowdsourcing of first-person viewpoint videos recorded on mobile devices. Collecting videos at a massive scale poses a number of major issues in terms of network planning. To improve the scalability with regards ...

Mobile messaging applications, such as WhatsApp, provide a free alternative for mobile texting on smartphones. Mobile messengers typically also share presence information about users to indicate when a user is online. We investigated the privacy ...

Mobile devices are capable of acting as smart assistances not only to serve their users but also to collaborate with each other remotely via wireless Internet to accomplish common goals. The latter is achieved by establishing a Social Private Cloud (SPC)...

Even though human activities may involve physical injuries, there is not much discussion in the academy of how ubiquitous computing could assess the risk related to them. This paper proposes an approach to evaluate the risk of activities considering two ...

Domestic food wastage is a growing problem for the environment and food security. Some causes of domestic food wastes are attributed to a consumer's behaviours during food purchasing, storage and consumption, such as: excessive food purchases and ...

A recent study revealed that every fourth German adult drinks less than 1.5 litres a day. Insufficient fluid intake can cause headache, lack of energy and lightheadedness. Signals can be used to be reminded of drinking. However, these are often missed ...

Using mobile phones while walking for activities that require continuous focus on the screen, such as texting, has become more and more popular in the last years. To avoid colliding with obstacles, such as lampposts and pedestrians, focus has to be ...

Tourists become increasingly dependent on mobile city guides to locate tourist services and retrieve information about nearby points of interest (POIs) when visiting unknown destinations. Although several city guides support the provision of ...

Mobile stereoscopic 3D (S3D) user experience (UX) design has not yet been widely studied. Stereoscopy in today's products is used for visual design purposes, whilst the potential for holistic interaction design and utilitarian aspects have been ...

This paper presents a scenario-based user study of mobile application concepts that would encourage interaction between people within close proximity. The scenarios demonstrate three themes of digital tickets-to-talk: informing who and what are around, ...

Social Devices (SDs) are mobile devices that are proactive in social settings and aim to encourage social interaction between co-located people. We conducted a study of people's reactions to SDs with an audio-based interface on a semi-functional ...

We report a pre-study and a three-week in-the-wild deployment of a non-moderated interactive public display prototype designed as a communication extension for an established community. A pre-study was conducted to map existing practices in order to ...

Pervasive games represent an exciting development in gaming which leverages the use of sensor, visualization and networking technologies to provide immerse live-action game experiences. The field of pervasive games has been intensively researched in the ...

Commercial apps for nearby search on mobile phones such as Qype, AroundMe, Foursquare, or Wikitude have gained huge popularity among smartphone users. Understanding the way how people use and interact with such applications is fundamental for improving ...

While privacy is often treated as an information centric issue, privacy issues in ubiquitous and mobile computing also encompass physical or territorial aspects, i.e., the right to be left alone or undisturbed. Disturbances that affect privacy often ...

Device-to-Device (D2D) communication is a potential strategy to release the mobile network from unnecessary data transfer, accelerate the responsiveness of end-to-end apps, and decentralize the provisioning of traditional services. D2D coordination is a ...

In order to invent and investigate new approaches for the use of enjoying live video, we suggest a combination of emerging mobile webcasting with artistic ambient video, which would enable a form of user generated broadcasts from individually selected ...

Recent years have seen a growing interest in supporting learning activities/scenarios that go beyond the traditional classroom context as well as the development of pervasive computing scenarios supported by display installations. In order to explore ...

This paper describes a user evaluation study of automated creation of mobile video remixes in three different event contexts. The evaluation contributes to the design process of the Automatic Video Remixing System, deepening knowledge to wider usage ...

This article presents an exploratory case study with a mobile application devised to promote social inclusion of visually impaired people through collaborative mapping considering changes in the local environment. General strategies and technological ...

In the future, transparent displays can be utilized as information and communication channels in our everyday environments. Home windows form an interesting, yet unexplored platform, which could be utilized in the future e.g. as a mixed reality display ...

Computer Vision (CV) approaches, e.g., as the basis for mobile Augmented Reality (AR), depend on continuous Internet access for image uploads and large-scale Internet databases to perform image recognition against comparison images. This dependency ...

Research efforts into indoor localisation have focused on improving the accuracy of location estimates. In this paper, we propose a novel approach called SIB that uses RSSI values from low-power transmissions to exclude the noisy measurements from usual ...

When users consult a trip planner, map or navigation system for directions, they are presented with several route options which often are evaluated based on shortest path or shortest duration. However, in some cases, users may require the choices of ...

Using online multimedia content on mobile devices is a power hungry activity and drains battery power very quickly. This poses a big challenge in using mobile devices with limited battery power for learning purposes using online educational multimedia. ...

Wireless sensor technologies have become popular in recent years as the cost of electronics decreases. In addition, various sensors were incorporated into a smartphone, which caused the integration of many applications into one device. Navigation is a ...

Finding a suitable time for a meeting is a common practical problem. The existing software solutions either cannot be used across heterogeneous calendar systems and organizations, or require manual effort and waiting. We employ design science to study ...

Public displays that allow users to interact with them through mid-air gestures are still relatively rare, as many applications rely on touch-based interaction. This paper introduces Information Wall, a gesture-controlled public information display that ...

Motion and location activities are essential to understanding human dynamics. This paper presents a method for discovering significant locations and individuals' daily routines from WiFi data, a data source considered more suitable for analyzing human ...
