Tourism studies have noted that insufficient attention has been paid to the experience and practices of the tourist. Tourism research does not help to explain the nature of modern mass tourism. The most detailed research that has been done is tourist information seeking, but the literature has tended to avoid detailed qualitative description, focusing more on broad categorizations of tourist practice...
Instead of the original wired IP networks, the mobile networks are used as the return channel in IP-QAM VOD system to take the advantage of their wireless data communication function and full coverage in cities. The mobiles are used as a virtual remoter of STB for demanding video programs and controlling their playing. The function of complex query for programs can be realized based on the mobile's...
FrontlineSMS and Ushahidi are both free and open source tools which allow for the collection, dissemination and visualization of data collected to and from the field. This paper outlines details of live demonstrations of the tools at the ICTD 2009 conference in Qatar.
This low-cost indoor navigation system runs on off-the-shelf camera phones. More than 2,000 users at four different large-scale events have already used it. The system uses built-in cameras to determine user location in real time by detecting unobtrusive fiduciary markers. The required infrastructure is limited to paper markers and static digital maps, and common devices are used, facilitating quick...
Recently, the damages from malware on the mobile devices are increasing rapidly though commercial anti-virus software detects the malware. Generally, the anti-virus program checks and heals well-known malware based on their signature which can identify itself. Though the malware attacks are evolved fast enough, anti-virus software based on signature cannot detect it effectively when they cannot update...
Along with the development of wireless technology and especially 3Gpsilas throw into commercial, the mobile value-added services gradually popular used, such as mobile automatic question and answer (Q/A) system. But the current mobile Q/A system mainly based on FAQ database, the question and answer can not be validated and updated by itself. So this paper attempts to implement a p2p based model updatable...
GUI of mobile application software has been used as important elements that users easily operate the software functions. Since it becomes established as an important factor of software success, GUI test is required for the software success. But its test takes much efforts and time. Therefore, we propose a method and automatic tool for mobile GUI test.
Considering the high packet losses and low, varying bandwidth of GPRS/EDGE network and limited computation power of handheld devices, we present and implement a novel SVC video-on-demand system for hand-held devices over GPRS/EDGE network. For the purpose of handling varying bitrate, we propose a priority based layer switching (PLS) adaptation scheme for SVC stream, which not only performs online...
