PURPOSE To quantify the central attention-diverting effect of hands-free cellular phone conversation on visual field awareness. DESIGN Experimental study. METHODS Twenty male and 21 female healthy participants performed a pretest and baseline Esterman visual field examinations with the Humphrey Systems Visual Field Analyzer II. During the consequent third examination, each participant engag...

In this number of Clinics we highlight an intriguing study by Narayanan et al., triggered by the tremendous expansion of the use of cellular phones. They exposed Wistar rats to frequent bursts of the vibratory stimulation (no ring tone) produced by cellular phones and found that such stimulus induces a deficit of spatial memory performance using the Morris water maze test. Both groups did exhib...

Dual-task studies assessed the effects of cellular-phone conversations on performance of a simulated driving task. Performance was not disrupted by listening to radio broadcasts or listening to a book on tape. Nor was it disrupted by a continuous shadowing task using a handheld phone, ruling out, in this case, dual-task interpretations associated with holding the phone, listening, or speaking, ...

In this chapter, a campus information providing system (CIPS) for cellular phones is proposed. By using this system, the search time to find the necessary information in the campus is reduced. Users can access the system using the cellular phone terminal and by clicking the links or by inserting a keyword in the form they can get easily the campus information. The system has four agents, which ...

We propose a virtual network computing (VNC) based architecture for accessing the desktops of remote computers from a cellular phone. A viewer is provided on the cellular phone that enables the user to see and manipulate the desktop of various remote systems such as MS Windows, Macintosh, and UNIX. The system to be accessed must be running a VNC server and it must be attached to a network. A pr...

Mobile phone use and wireless communication technology have grown explosively over the past decades. This rapid growth has caused widespread global concern about the potential detrimental effects of this technology on human health. Stem cells generate specialized cell types of the tissue in which they reside through normal differentiation pathways. Considering the undeniable importance of stem ...

Advances in the Internet and telecommunications technologies have spurred many research efforts in integrated communication systems which integrate heterogeneous devices (such as desktop phone, cellular phone, PSTN phone or pager) and networks (like the Public Switch Telephone Network, cellular networks, or the pager networks) on top of the Internet and enables communications among any devices ...
