Cloud computing and mobile computing are two of the most influential technologies that look set to change the face of computing in the coming years. Combination of the two provides us with an unprecedented opportunity to provide highly portable and yet content-rich and computation-intensive services to the end user. In this paper we investigate the possibility of using code/task offload techniques...
The technological progress of mobile devices, the relevance of Internet in today's society and the booming mobile market have revolutionized mobile software in recent years and significantly impact the software quality of mobile interactive devices. Mobile software gets more and more capable and complex, which allows developers to apply well-established quality methods and models, e.g. from the area...
The key question of this paper is what will come as the next e-book after the present e-book, which is merely a digitalized version of the paper book? This paper suggests a new e-book model that can be realized with the advance of media technology, from the viewpoint of three elements of books. In particular, the Multi-Device e-Book prototype was made and simulated. This simulation sbggests novel...
It is a fact that mobile devices have emerged as the core interaction platforms for Human-to-Machine communication. Mixed Reality has reached mobile devices indeed. However, there are still issues regarding its consumption beyond stand-alone applications, such as Layar and Wikitude. This article states the benefits of consuming and integrating Mixed Reality with mobile services through our tailored...
Creative and ad-hoc work often involves non-digital artifacts, such as whiteboards and post-it notes. The preferred method of brainstorming and idea development, while facilitating work among collocated participants, makes it particularly tricky to involve remote participants, not even mentioning cases where live social involvement is required and the number and location of remote participants can...
When studying the use of ambient audio to generate a secure cryptographic shared key among mobile phones, we encounter a misalignment problem for recorded audio data. The diversity in software and hardware causes mobile phones to produce badly-aligned audio chunks. It decreases the identical fraction in audio samples recorded in nearby mobile phones and consequently the common information available...
In this study, basic physical activities are classified using 3-axis accelerometer signals. The system is mainly proposed for mobile devices and basically objected to detect whether a person carrying this hardware is walking, running, or travelling in a car or bus. The developed system considers the accelerometer signals in constant bins and performs a real-time classification. The proposed system...
In the past years pervasive devices, especially mobile phones, have increased in complexity. Particularly the proliferation of features is tough to handle, not least because new features might require a hardware update or conflict with existing features. In order to overcome these issues we propose an approach which tackles the problem at an early development phase by increasing the semantic requirement...
This study was conducted to compare the typing performance of subjects inputting random alphabet characters using software keyboards on touchpanel mobile devices and hardware keyboards (subjects n=67, 31.0 ± 11.1 years of age) Hardware keyboards showed significantly better performance for input speeds, error rates, and subjective rate of usability. As a result, even those who showed slow input spends...
In this paper, the design and implementation of a wireless remote power controller for home automation based on GSM is introduced. The controller can remotely control the power in our homes through TC35 module at anytime and from anywhere. The controller consists of controlling center and remote receiving module. A prototype of the controller is implemented, and the experiment results show that the...
People visiting a foreign city are often not comfortable with the public transport system. This paper describes a system designed help passengers not only to find a suitable route but also to identify the correct bus. Different ways for recognising buses are explained and examined for practicability in the city of Berlin. An actual test case for the best fitting scenario was created and tested in...
Graphics generation and display play a very important role in all functions of equipments on aircraft platform. Effective, accurate and real-time display of graphics flight parameters is an indispensable requirement for high-performance aircraft. In this paper, a graphics function lib based on OpenGL ES specification is detailedly introduced, which is designed to run on given special embedded graphics...
In this paper, we present different acceleration concepts for the Robust Header Compression version 2 (ROHCv2) algorithms in Long Term Evolution (LTE) handsets. First, we explore the potential performance improvements and energy savings by adopting scratchpad memories at various sizes. Second, dedicated hardware accelerators with different data transfer modes are compared in terms of processing speed...
In this paper, we suggest a multiple streaming method with virtualized network interface in wireless environment. A virtualization provides new interface mechanism to system by mitigating restrictions of hardware. Our virtualized system which has virtualized network interface can communicate with multiple AP(Access Point)s as system has several network interfaces in wireless environment. Each several...
IExchange is a new technology in the Motorola iDEN system. It transmits data packets over the dispatch channel and achieves very high efficiency multicast of messages. An investigation was done based on the published technical documents from Motorola. As an output of the investigation, this paper discusses the mechanism of this technology, compares it with technologies providing similar services and...
This paper proposes integration of secure agents with a secure communication infrastructure in order to provide rapid information gathering platform from various information sources and actors participating in a crisis situation. The role of agents is primarily a coordinated collection of information. The secure communication infrastructure (SCI) provides communication services for voice and data...
3D display applications are among focal topics in the field of the mobile communication, In order to transplant a variety of 3D display technologies to the real-time uses based on the existing widely used mobile platforms, in this paper we propose a good 3D flip algorithm that can be utilized on the J2ME platform. The principle of 3D flip algorithm is derived for display interface using mathematical...
The high density ofWiFi Access Points and large unlicensed RF bandwidth over which they operate makes them good candidates to alleviate cellular network's limitations. However, maintaining connectivity through WiFi results in depleting the mobile phone's battery in a very short time. We propose WiZi-Cloud, a system that utilizes a dual WiFi-ZigBee radio on mobile phones and Access Points, supported...
Incorporation of a good machine vision into mobile device can create a powerful application. With such advancement, mobile users can use their existing smartphone as their third-eye to perceive the world. This paper introduces a framework using the smartphone to increase ambient intelligence and road safety of moving vehicles through traffic sign alert application. The driver is alerted of the incoming...
Near Field Communication (NFC) technology enables devices to communicate wirelessly within proximity distance. These NFC devices are often embedded into smart posters that offer the ability to exchange small files, photos and contact details. The Nokia 6212 Classic is currently the most popular NFC phone. It allows users to easily exchange digital objects using the NFC interface. To do so, two phones...
