Vehicle Information

A transit vehicle information system that delivers estimated departure times for buses at user-selectable geographic locations to Internet-enabled mobile devices is reported. The system is not merely schedule based; it makes use of real-time vehicle position reports to predict travel times to future locations. How the physical restrictions of mobile devices (e.g., screen size and input options) affect user interaction and data presentation is discussed. The system is hosted on the World Wide Web and is freely available. An overview of the system architecture is provided and some preliminary usage results are presented.

This chapter examines the adoption of free wireless Internet parks (iPark) by Qatari citizens as a means of accessing electronic services from public parks. The Qatar government has launched the iPark concept with a view of providing free internet access for all citizens while enjoying the outdoors. This concept is enabled by an ICT infrastructure and broadband facilities, which is considered as regional good practice. By offering free wireless Internet access, the Qatari government encourages its citizens to actively participate in the global information society with a view of bridging the digital divide. Using a survey based study this research set out to examine the Qatari citizens’ perceptions of the iPark initiative. Results of the survey showed that there is a positive level of relation between the independent variables, usefulness, ease of use, Internet safety, and Internet speed/response time and one dependent variable, intention to use the iPark in Qatar. The chapter provides a discussion on the key findings, research implications, limitations, and future directions for the iPark initiative in Qatar.

Efficient Video

In recent years, mobile phones have become the de facto system of communication across the planet. Mobile phones have helped increase economic growth and critical response in many parts of the world. Mobile phones are even being used for data transmission. However, little academic research has been done on the specific problem of streaming real time video originating from the cameras of mobile devices over cell phone networks. There are many factors that complicate this problem including the limited computational resources of mobile phones, the low and variable bandwidth of cell phone networks, and the need for video compression and streaming algorithms that can be supported by both the mobile phones and cell phone networks. This chapter examines the problems involved and discusses on-going research on the topic. The main goal of this chapter is to identify the real time constraints and challenges of compressing and streaming video from mobile devices for the purpose of designing efficient video compression and streaming techniques that are able to work within the constraints of the limited computational resources and bandwidth available to mobile devices.
