While visualization has been widely used as a data presentation tool in both desktop and mobile devices, the rapid visualization of information from images is still underexplored. In this work, we present a smartphone image acquisition and visualization ...

The ubiquity of the smartphones makes them ideal platforms for generating in-situ content. In well-attended events, photos captured by attendees have diverse views that could be subjected to occlusion and abnormal lighting effects that could obscure the ...

Advanced 3D mobile devices attract a lot of attentions for 3D visualization nowadays. Stereoscopic images and video taken from the 3D mobile devices are uncomfortable for 3D viewing experiences due to the limited hardware for stereoscopic 3D ...

Augmented reality (AR) aims to render the world that users see and overlay information that reflects the real physical dynamics. The digital view could be potentially projected near the Point-of-Interest (POI) in a way that makes the virtual view ...

Augmented reality (AR) applications have recently become popular on modern smartphones. We explore the effectiveness of this mobile AR technology in the context of grocery shopping, in particular as a means to assist shoppers in making healthier ...

Pervasive social networking (PSN) supports online and instant social activities and communications in a universal and pervasive manner on the basis of heterogeneous networks. However, at the same time, when mobile users expect useful and valuable ...

Participatory sensing is a promising sensing paradigm that enables collection, processing, dissemination and analysis of the phenomena of interest by ordinary citizens through their handheld sensing devices. Participatory sensing has huge potential in ...

In this work we have developed a photography model based on machine learning which can assist a user in capturing high quality photographs. As scene composition and camera parameters play a vital role in aesthetics of a captured image, the proposed ...

The aim of this article is to present and discuss an innovative methodology aimed at accessing digitized copies of historical tape music audio documents; the methodology leverages on the multimedia and multisensory capabilities of mobile devices to ...

Driving is an integral part of our everyday lives, but it is also a time when people are uniquely vulnerable. Previous research has demonstrated that not only does listening to suitable music while driving not impair driving performance, but it could ...

On-screen gamepads are increasingly used as controllers for video games on distant screens, yet lack the typical tactile feedback known from hardware controllers. We conducted a comparative lab study to investigate four smartphone gamepads inspired by ...

This article describes how an experimental platform for social, mobile and ubiquitous computing has been used in a wide-ranging longitudinal “in the wild” case study of the platform with a set of third-party services. The article outlines some of the ...

The need for human-centered, affective multimedia interfaces has motivated research in automatic emotion recognition. In this article, we focus on facial emotion recognition. Specifically, we target a domain in which speakers produce emotional facial ...

This article considers the problem of cross-modal retrieval, such as using a text query to search for images and vice-versa. Based on different autoencoders, several novel models are proposed here for solving this problem. These models are constructed ...
