An experiment comparing grids and item-by-item formats in web surveys completed through PCs and smartphones

Some respondents already complete web surveys via mobile devices. These devices vary at several levels from PCs. In particular, we expect differences when grid questions are used due to the lower visibility on mobile devices and because in questionnaires optimized to be completed through smartphones, grids are split up into an item-by-item format.This paper reports the results of a two-wave experiment conducted in Spain in 2015, comparing three groups: PCs, smartphones not-optimized, or smartphones optimized.We found similar levels of interitem correlations, longer completion times for grid questions for smartphone respondents, and sometimes less non-differentiation for PCs. Thus, using the item-by-item format for smartphones and PCs seems the most appropriate way to improve comparability.     

Implementation of an open platform for 3D spatial information based on WebGL

VWorld is run by the Ministry of Land, Infrastructure, and Transport of South Korea and provides national spatial information, such as aerial images, digital elevation models, and 3D structural models. We propose herein an open platform for 3D spatial information based on WebGL using spatial information from VWorld. WebGL is a web‐based graphics library and has the advantage of being compatible with various web browsers. Our open platform is also compatible with various web browsers. Accordingly, it is easily accessible via the VWorld site and uses the three‐dimensional (3D) map program. In this study, we describe the proposed platform configuration, and the requests, management, and visualization approaches for VWorld spatial information data. Our aim is to establish an approach that will provide a stable rendering speed even on a low‐end personal computer without a graphics processing unit based on a quadtree structure. We expect that users will be able to visualize 3D spatial information through the VWorld open platform, and that the proposed platform will become the basis for various applications.     

The Feasibility of Navigation Algorithms on Smartphones using J2ME

Embedded systems are considered one of the areas with more potential for future innovations. Two embedded fields that will most certainly take a primary role in future innovations are mobile robotics and mobile computing. Mobile robots and smartphones are growing in number and functionalities, becoming a presence in our daily life. In this paper, we study the current feasibility of a smartphone to execute navigation algorithms and provide autonomous control, e.g., for a mobile robot. We tested four navigation problems: Mapping, Localization, Simultaneous Localization and Mapping, and Path Planning. We selected representative algorithms for the navigation problems, developed them in J2ME, and performed tests on the field. Results show the current mobile Java capacity for executing computationally demanding algorithms and reveal the real possibility of using smartphones for autonomous navigation.

Modeap: Moving Desktop Application to Mobile Cloud Service

Thanks to the availability of various mobile applications, lots of users shift from desktop environments, e.g., PCs and laptops, to mobile devices, e.g., smartphones and tablets. However, there are still some desktop applications without counterparts on mobile devices, such as some integrated development environments (e.g., eclipse) and automatic industry control systems. In this paper, we propose Modeap, a platform-independent mobile cloud service that can push all desktop applications developed for various operating systems from cloud servers to mobile devices. Modeap follows a design principle of complete detachment and regeneration of desktop user interface, i.e., the essential graphical primitives of the original desktop applications will be intercepted and then translated into standard web-based graphical primitives such that the interactions between users and remote cloud applications become possible via mobile web browsers. In this way, all desktop applications built upon the same set of graphical primitives can be used on mobile devices in great flexibility without installing any new software. We have developed a proof-of-concept prototype that provides Windows applications from cloud server to mobile web browsers. The results of extensive experiments show that the proposed framework can achieve our design goals with low latency and bandwidth consumption.     

云计算环境下的流量控制和负载均衡策略

传统的web应用使用专用的硬件资源,这些硬件资源仅为某种特定的应用提供服务。而在云计算环境下,许多不同的web应用需要共享云平台资源。因此,当将传统的web应用迁移到云平台下时,将会出现一系列的挑战,主要的问题是面对大量不同应用请求时的流量控制和负载均衡控制。基于此,提出了云计算环境下的分布式路由系统Distributed Routing System(DRS),DRS主要用于解决当许多web应用在云环境下同时运行时面临的流量控制和负载均衡问题。实验表明DRS能够有效地转发应用请求到后台轻负载服务器,并且有着较低的时延。     

A smartphone‐centric platform for remote health monitoring of heart failure

Heart failure is a chronic disease that alternates intense and weak phases and requires repeated and frequent hospital treatments. The use of automatic instruments for a remote and ubiquitous monitoring of biological parameters relevant to heart failure pathophysiology offers new perspectives to improve the patients' quality of life and the efficacy of the treatment. The platform described in this paper represents an implementation of an automatic remote monitoring tool where smartphones play a crucial role. They are not employed just to communicate through traditional client‐server applications and they are not only the hub of information sent by sensors, but they also act as intelligent processors and autonomous sensors of the patients' motion through a high‐accuracy activity recognition algorithm. The proposed platform combines the evolution of health systems and the consequent needs of modern telemedicine with the current context‐aware capability of recent smartphones, obtained by implementing specific algorithmic solutions, and with the anything, anytime, and anywhere communication capability of the pervasive communications paradigm. Performance evaluation focuses on the accuracy of the activity recognition estimation, on its applicability to real life, and on the data exchange between smartphones and medical server, allowing to envisage the potential of the designed platform.
