The goal of this study is to introduce the theoretical foundation of a new concept in medical technology that is centered on the cellular phone. The concept was conceived with the needs of medically underserved regions of Mexico in mind. The application introduced here deals with undetected intraperitoneal bleeding that is responsible for the death of one of four women who die at childbirths an...

PROBLEM Assessment of drivers' on-road workload is an important traffic safety consideration. This study was conducted to examine the effects of cellular phone communication on driving performance, with particular emphasis on variations in task demand in different traffic situations. METHOD Twelve participants were asked to drive on urban roads and motorways with or without concomitant mathem...

In this paper, we propose a novel feature optimization method to build a cascade Adaboost face detector for real-time applications on cellular phone, such as teleconferencing, user interfaces, and security access control. AdaBoost algorithm selects a set of features and combines them into a final strong classifier. However, conventional AdaBoost is a sequential forward search procedure using th...

Cellular phones can be used as mobile sensors, continuously logging users’ behavior including movement, communication and proximity to others. While it is well understood that data generated from mobile phones includes a record of phone calls, there are also more sophisticated data types, such as Bluetooth or cell tower proximity logging, which reveal movement patterns and day-to-day human inte...

This paper describes our efforts towards cross-domain acoustic training for Large Vocabulary Continuous Speech Recognition (LVCSR) systems. We used weighted multi-style training by pooling insufficient telephony landline and cellular data with down sampled wide band clean data to develop better hybrid acoustic models. We explored the effects on decision tree size to accuracy by approximately 10...

In this study, 150 subjects observed a 25-minute video driving sequence containing 45 highway traffic situations to which they were expected to respond by manipulation of simulated vehicle controls. Each situation occurred under five conditions of distraction: placing a cellular phone call, carrying on a causal cellular phone conversation, carrying on an intense cellular phone conversation, tun...

This paper addresses the problem of speech recognition through telephonic networks. When the communication channel is unknown, the important mismatch between training data and signal encountered in recognition phase decreases drastically the performances of the recognition systems. In this context, we compare a classical approach: the noise compensation method with novel robust networks modelli...

The number of cellular phone subscribers is increasing every year and there have been reports of health disorders related to the high-frequency radio waves. This paper considers the dependence of Thai university and high school students on cellular phones. A survey form (cellular phone dependence questionnaire: CPDQ) was distributed to 181 female and 177 male Thai university students and to 240...

We describe the implementation of a cellular-phone based speech translation system without telephone quality speech database or special CT hardware. The purpose is to quickly build a prototype service system that can be used for data collection with real users. To train the acoustic model for the speech recognition system, available high-quality databases were made usable by 1.) appropriate dow...

In this work we present a simulation system to control a mobile robot using a cell phone. We exploit the cellular telephony technology to communicate and command a robot provided with a modem in a simulation environment. The system considers telerobotics can be performed using phone tones or sending text messages via SMS. Due the cellular telephony is expensive, the simulation system give us th...
