The Focus of Attention (FOA) Problem is, given a set of targets and a set of sensors in the plane, to track the targets with ‘maximum possible accuracy’. The accuracy is measured in terms of the angle subtended by the sensor pairs at the assigned targets. In this paper, we consider a scenario in which we are given n targets on a line l and 2n sensors on a line m such that l || m and the objecti...

In this report we present an approach to low bitrate video teleconferencing by focusing attention on important information. We show that by selectively degrading the quality of less important regions, more important regions can be sent without loss of quality but with greatly reduced bandwidth requirements. Low bitrate transmission for real-time video delivery over a dynamic network is achieved...

newell's learning stages model is a learning model based on dynamic systems theory which is divided to three stages based on the relationship among learners' degree of freedom. the aim of this study was to investigate the effect of attention focus of instruction on learning a simple skill (throwing darts) and a complex skill (non-dominant foot chip shot). thestudyconsistedoftwoexperim...

Background. Previous studies have shown that an external versus the internal focus of attention is an effective and efficient method to improve athleteschr('39') performance under anxious conditions. Objectives. The current study aimed to assess the effect of the practice with a distinct focus of attention on the penalty kicking performance of adolescent soccer players with different expertise...

the aim of this study was to investigate the effect of focus of attention on learning dart throwing in mentally retarded children.in this quasi-experimental study, 22 mentally retarded boys (age 10-12 years old) were randomly selected according to iq (50-70) and were assigned to two homogenous attention (internal, external) groups after the pretest and a training session according to the obtain...

Detriments to performance under pressure are common in many settings, from public speaking skilled sports or music performances. In the last few decades, scientists have suggested that quality and accuracy of movements can depend on what performer attends while executing action, with an external focus attention directed at effects movement environment resulting better than internal focus, where...
