MMORPGs and Their Effect on Players

The purpose of this essay is to explore the popularity and effects of video games in the MMORPG genre. Games and play have been a part of human culture for an exceptionally long time, and in the recent decades video games have a become a large medium to continue this. Studying how video games, such as MMORPGs, can be used in order to advance life skills is important to understand the future of human development. By researching other studies done on various topics of related to MMORPG, I developed the idea that this genre of video games could be very impactful on future human development. The skills taught while playing a MMORPG can have real world applications and have shown preliminary success in doing so. Such skills include rapid decision making, civic responsibility, and social skills have been shown to improve as players play in this fantasy world. As such, further research into the full impact of MMORPGs needs to be done to fully understand the full scope of skills being utilized and developed during this form of play

Realtime Multilevel Crowd Tracking using Reciprocal Velocity Obstacles

We present a novel, realtime algorithm to compute the trajectory of each pedestrian in moderately dense crowd scenes. Our formulation is based on an adaptive particle filtering scheme that uses a multi-agent motion model based on velocity-obstacles, and takes into account local interactions as well as physical and personal constraints of each pedestrian. Our method dynamically changes the number of particles allocated to each pedestrian based on different confidence metrics. Additionally, we use a new high-definition crowd video dataset, which is used to evaluate the performance of different pedestrian tracking algorithms. This dataset consists of videos of indoor and outdoor scenes, recorded at different locations with 30-80 pedestrians. We highlight the performance benefits of our algorithm over prior techniques using this dataset. In practice, our algorithm can compute trajectories of tens of pedestrians on a multi-core desktop CPU at interactive rates (27-30 frames per second). To the best of our knowledge, our approach is 4-5 times faster than prior methods, which provide similar accuracy
