Smart Surveillance using PDA

The aim of this research is to develop a fast and reliable surveillance system based on a personal digital assistant (PDA) device. This is to extend the capability of the device to detect moving objects which is already available in personal computers. Secondly, to compare the performance between Background subtraction (BS) and Temporal Frame Differencing (TFD) techniques for PDA platform as to...

Personalized Adaptive Pda Interface

User demands for usability in mobile context due to the small size of personal data assistants (PDAs) challenge traditional input design. An on-screen keyboard that offers an easier and faster method of entering text with a pen on PDAs, has been developed. We have developed a method for adapting its predictive ability according to user’s personal word usage, input context and syntax rules. Freq...

Ef£cient PDA Synchronization

Modern Personal Digital Assistant (PDA) architectures often utilize a wholesale data transfer protocol known as “slow sync” for synchronizing PDAs with Personal Computers (PCs). This approach is markedly inef£cient with respect to bandwidth usage, latency, and energy consumption, since the PDA and PC typically share many common records. We propose, analyze, and implement a novel PDA synchroniza...

PDA Operating Systems

This paper describes the operating systems – OS – for personal digital assistants – PDAs. Three systems, namely Windows CE, Palm OS, and Symbian OS are discussed. At first the general features of PDA operating systems are introduced. Then the differences of the three systems are discussed from the functionality, usability, and scalability of each system. After that some future predictions are g...
