In this paper we analyze the interaction of blind users with the iPad, the popular mobile tablet device that (thanks to its pre-installed VoiceOver screen reader) is also accessible to the blind. Specifically, we consider the gestures offered by VoiceOver to make the device usable by the blind users. Our analysis confirms that VoiceOver makes the iPad device basically accessible to blind users,...

This study aimed to investigate the use of iPads as a learning tool for college-level EFL students and to explore these language learners’ perceptions of iPad reading. Drawn from an intermediate EFL reading class, three students with limited experiences of iPad reading participated in this study. Data from weekly journals and interviews showed that the iPads’ palm size, light weight, and access...

In recent years, numerous vision and learning tasks have been (re)formulated as nonconvex and nonsmooth programmings (NNPs). Although some algorithms have been proposed for particular problems, designing fast and flexible optimization schemes with theoretical guarantee is a challenging task for general NNPs. It has been investigated that performing inexact inner iterations often benefit to spec...

OBJECTIVES The use of effective contraception can decrease the incidence of unplanned pregnancy among adolescents. This study aims to examine the effectiveness of an iPad-based application (app) on improving adolescent girls' sexual health knowledge and on its ability to influence their intentions to use effective contraception. STUDY DESIGN This was a prospective study of girls aged 12 to 18...

mobile ad-hoc networks (manets) by contrast of other networks have more vulnerability because of having nature properties such as dynamic topology and no infrastructure. therefore, a considerable challenge for these networks, is a method expansion that to be able to specify anomalies with high accuracy at network dynamic topology alternation. in this paper, two methods proposed for dynamic anom...

Many new melodic instruments use a touch sensitive surface with notes arranged in a two-dimensional grid. Most of these arrange notes in chromatic half-steps along the horizontal axis and in intervals of 4ths along the vertical axis. Although many alternatives exist, this arrangement, which resembles that of a bass guitar, is quickly becoming the de facto standard. In this study we present expe...

Inter-Device Multiplayer and Performance Optimization in Games for Modern Mobile Devices In this thesis we explore the use of a large-screen mobile device, the iPad, in multiplayer games across multiple modern mobile devices. Specifically, the Wi-Fi capability on these devices are used to implement and evaluate multiplayer where the iPad acts as a game surface while smaller devices such as the ...
