This study investigated the effects of video game play on aggression. Using the General Aggression Model, as applied to video games by Anderson and Bushman, [2002] this study measured physiological arousal, state hostility, and how aggressively participants would respond to three hypothetical scenarios. In addition, this study measured each of these variables multiple times to gauge how aggress...

OBJECTIVE AND BACKGROUND Objective monitoring of cough may be preferred to subjective reporting of the symptom in clinical and research settings. Therefore, a self-contained, ambulatory cough monitoring system is needed that is non-invasive, usable for children and adults of all ages, inexpensive, and highly accurate with easy to use analysis software. METHODOLOGY After development of a new d...

We report on an exploratory study where the first 60 seconds of the video recording of a user interaction are used to predict the user’s experienced task difficulty. This approach builds on previous work on “thin slices” of human-human behavior, and applies it to humancomputer interaction. In the scenario of interacting with a photocopy machine, automated video coding showed that the Activity a...

The use of violent video games has been often linked to increase of aggressive behavior. According to the General Aggression Model, one of the central mechanisms for this aggressiveness inducing impact is an emotional desensitization process resulting from long lasting repeated violent game playing. This desensitization should evidence itself in a lack of empathy. Recent research has focused pr...

This paper describes a wearable system for the assessment of swim performance focusing on the description of the system and especially on the novel method for data transmission in water, and the algorithm used for extracting some parameters for the qualitative assessment of the performance. We placed a 3-axes Inertial Measurement Unit (IMU) on the athlete’s back in a specific swimsuit, which al...

The game genre is an important feature for organizing, accessing and developing video games; however the choice of the genre during the process of video games making requires expertise and thorough study which can sometimes lead to unexpected issues due to the bad choice that can affect the final result. In this paper, we will present the application of analytic hierarchical process method “AHP...

In this paper, I present a method for determining the location of human hands from a video recording of wide gestures. This method utilizes various techniques in image processing, including color filtering, motion filtering, noise reduction, and region discovery. Additionally, it proposes the use of optical flow as additional information in determine the rough location of the hands.

BACKGROUND Providing patients with a video recording of their visit with a medical professional is a common-sense method for improving patient-provider communication. OBJECTIVE To describe the patient and provider experiences to video recording clinical medical encounters and providing the patient with a copy of the video for informational purposes. METHODS Since 2009, over 2,800 patients o...

This study was divided into two complementary parts. In Part 1, we proposed a novel paddle strokes analysis based on the force signal from a 30-s all-out tethered test; and compared these results with video recordings. In Part 2, we investigated the relationship between force data from the same test with paddle stroke results from both methods. Eleven male elite slalom kayakers (Brazilian natio...

Video-oculography (VOG) is a non-intrusive method used to estimate gaze. The method is based on a remote camera(s) that provides images of the eyes that are processed by a computer to estimate the point at which the subject is gazing in the area of interest. Normally, infrared (IR) light-emitting diodes (LEDs) are used in the system, as this light is not visible to humans. The objective of the ...
