TiltType is a novel text entry technique for mobile devices. To enter a character, the user tilts the device and presses one or more buttons. The character chosen depends on the button pressed, the direction of tilt, and the angle of tilt. TiltType consumes ...

This research demonstrates a tariff balancing technique between subscription and usage in mobile networks based on cost and demand, something which is not fully considered by operators. The cost of provisioning access in wireless networks is negligible ...

The most recent advances in ubiquitous computing technologies have brought augmentation of objects to context-aware and social supports. Although most students prefer intensive reading on tangible books, few studies have been done on augmenting reading ...

We describe a prototype implementation of a future mobile phone called CyPhone. In addition to voice calls, it has been designed to support context-specific and multi-user multimedia services in an augmented reality manner. Context-awareness has been ...

Mobile services are steadily gaining greater foothold in everyday life, both in leisure and business. However, a real mobile services breakthrough, other than voice calls and SMS, has not yet been realized. This study focuses on how different dimensions ...

Wearable computers are still a niche. Several wearable computers fail to meet the complex demands that users place on them. Multiple factors, such as usability, size, weight, safety, ruggedness, fashion, and harsh operational environments, must be addressed. ...

Present Augmented Reality systems are isolated islands with no or little capability to receive 3D information from the outside world. In this paper we describe how Google Earth can be used to transform the physical world into an AR mailbox. We demonstrate ...

Massively Multiplayer Online Game (MMOG) is the recently popular game genre that is capable of supporting more than thousands of players in a persistence game world concurrently. With the growing of mobile game market size and improvement of wireless ...

Current methods of conceiving, engineering and using mobile technology typically embody a single integrated design philosophy. This integrated design approach seeks to combine as many features and functions into a single device as possible. In this manner ...

This paper describes a system for ubiquitous interaction that does not require users to carry any physical devices. In this system, the environment is instrumented with camera/processor combinations that watch users while protecting their privacy. Any ...

This paper presents an assessment of the communication overheads of IPsec and evaluates the feasibility of deploying it on handheld devices for the UMTS architecture. A wide range of different cryptographic algorithms are used in conjunction with IPsec, ...

We propose a collaborative environment for semantic-enabled mobile devices (e.g. PDAs, cell phones, laptops) in peer to peer scenarios. Within the environment, resource discovery is performed exploiting technologies and techniques for knowledge representation ...

Throughout the last decade, there has been an alarming increase in obesity prevalence among adults and teens throughout the world. Obesity has been found to increase the risk of developing diabetes, cardiovascular diseases, and some cancers. Due to the ...

This paper reports on the challenge to extend an existing distributed camera surveillance security application with Bluetooth driven wireless communication using handheld PC's. The main focus is on the engineering aspect of the development of BlueGuard. ...

Tagged Sub-optimal code (TSC) is a new codingtechnique presented in this paper to speed up stringmatching over compressed databases on PDAs. TSCis a variable-length sub-optimal code that supportsminimal prefix property. It always determines itscodeword ...

This article describes a development CDMA LBS in order to apply to Test Bed for Control System of Underground Infrastructure Fire Accident, a part of project that "An Intelligent Convergence System of Urban Information for Smart(Ubiquitous) Cities". ...
