The drive-recorder records automobile accidents and/or near-misses data. To realize the practical use of drive-recorders in automobiles, a fleet test was conducted on 202 cars and trucks that were in regular use on roads. Some of the tested drive-recorders were video drive-recorders (VDR) equipped with a video recording unit to obtain visual data on accidents and near-misses from the driver's v...

The paper presents our approach to studying collaborative practices of trauma teams during trauma resuscitation, a fastpaced and information-laden process of evaluating critically injured patients early after injury. We conducted a series of studies in a Level 1 trauma center using field observations and video recording. Our ability to use video recording was limited since human subject protect...

Video game play has become a common leisure activity all around the world. To reveal possible effects of playing video games, we measured saccades elicited by video game players (VGPs) and non-players (NVGPs) in two oculomotor tasks. First, our subjects performed a double-step task. Second, we asked our subjects to move their gaze opposite to the appearance of a visual target, i.e. to perform a...

Digital television and digital video recorders (DVRs) open up new possibilities for interactive television (iTV) advertising. Little is known about whether iTV advertising will be more effective than traditional linear TV advertising and what iTV ad models are more effective than others. This paper summarises the few studies that have been published so far. However, the main contribution of thi...

The aim of this study was to analyse the adjustments in technique made by a basketball player when shooting against an opponent. The subjects used consisted of 10 professional basketball players of the Spanish First Division League. Three-dimensional motion analysis based on video recordings (50 Hz) was used to obtain the kinematic characteristics of basketball jump shots with and without an op...

BACKGROUND Most wearable devices that measure movement in workplaces cannot determine the context in which people spend time. This study examined the accuracy of Bluetooth sensing (10-second intervals) via the ActiGraph GT9X Link monitor to determine location in an office setting, using two simple, bespoke algorithms. METHODS For one work day (mean±SD 6.2±1.1 hours), 30 office workers (30% me...

While comparative research on contagious yawning has grown substantially in the past few years, both the interpersonal factors influencing this response and the sensory modalities involved in its activation in humans remain relatively unknown. Extending upon previous studies showing various in-group and status effects in non-human great apes, we performed an initial study to investigate how the...

A kinematical model of the ski jumper's body pose at the beginning of take-off was proposed. A method of measuring skier's body coordinates based on the results of video recordings and office information technologies was created. Kinematical parameters of the skier's body pose at the beginning of take-off were determined using sport competition results of 33 ski jumpers. Five parameters of the ...

In some young children brought by their parents for diagnosis of acute life-threatening events investigations suggested imposed apnoea as the cause rather than spontaneous occurrence. Covert video surveillance of the cot in which the baby was monitored allowed confirmation or rebuttal of this diagnosis. That parents were not informed of the video recording was essential for diagnosis and we ass...

The origins of the bilingual advantage in various cognitive tasks are largely unknown. We tested the hypothesis that bilinguals' early capacities to track their native languages separately and learn about the properties of each may be at the origin of such differences. Spanish-Catalan bilingual and Spanish or Catalan monolingual infants watched silent video recordings of French-English bilingua...
