We describe a highly portable head-mounted display designed for use in action sports such as skiing and snowboarding. The low field-of-view, monocular display is designed to keep distraction to a minimum and not impede the mobility of the wearer. Implications of the location of the monocular display are discussed. The driving electronics and power source are small enough so that no tethering is needed,...
Mobility models play an influential role in the simulation studies of mobile ad hoc networks (MANETs). Realism and simplicity are two attractive properties of mobility models, and achieving both together in modeling mobility has been a challenging task. Recently, a framework of moblity models called destination guided mobility (DGM) models for MANETs was proposed. This framework can be used to develop...
Traditional E-Commerce applications have evolved in the last years due to the growth of the mobile environment, creating a new research area known as U-Commerce. The application of these techniques in the banking environment has been a direct outcome in order to enhance the services offered to end users. In this paper, we present a context-aware mobile recommender system based on real banking data...
Proxies can be used as gateways between remote resources and mobile devices to deal with the challenges resulted from disconnections and the limited resources of mobile devices. This paper describes a proxy-based infrastructure that provides proxy services to support mobile device applications. Proxy services can be thought of as a library of functions where the functions execute on a proxy and serve...
In this paper, we describe a mobile application that synchronizes the playback of a video stream among a group of mobile devices while the video playback is controlled (e.g. pause, resume, seek) by one of the devices. This feature allows a group of people to collaborate remotely in real-time through watching the same video on their mobile devices. To make this application work for heterogeneous mobile...
Participatory sensing (PS) systems are a new emerging sensing paradigm based on the participation of cellular users. While they present interesting characteristics, such as spatiotemporal granularity and low cost, they also create new problems and challenges. One key challenge in PS systems is that of the determination of the locations and number of users where to obtain samples from so that we can...
Music Information Retrieval (MIR) is a crucial topic in the domain of information retrieval. According to major characteristics of music, Query-by-Humming system retrieves interesting music by finding melody that contains similar or equal melody to the humming query. Basing on the designed fuzzy inference model a novel Query-by-Humming/Singing system is proposed to extract pitch contour information...
