The Effects of Latency and Jitter on a First Person Shooter: Team Fortress 2

This paper describes the effects of latency and jitter on the enjoyment and performance of playing the online multiplayer first person shooter game Team Fortress 2. We ran a study to measure the performance of the player and the enjoyment of the game under various latency and jitter conditions. We analyzed data gathered from the game and questionnaires to find correlations for player performance or enjoyment at latency and high jitter versus just high latency. Our results suggest that higher latency makes a difference in gameplay, but there is no correlation for players performing better or worse with latency and jitter compared to just high latency

A Behavioral Model System for Implicit Mobile Authentication

Smartphones are increasingly essential to users’ everyday lives. Security concerns of data compromises are growing, and explicit authentication methods are proving to be inconvenient and insufficient. Meanwhile, users demand quicker and more secure authentication. To address this, a user can be authenticated continuously and implicitly, through understanding consistency in their behavior. This research project develops a Behavioral Model System (BMS) that records users’ behavioral metrics on an Android device and sends them to a server to develop a behavioral model for the user. Once a strong model is generated with TensorFlow, a user’s most recent behavior is queried against the model to authenticate them. The model is tested across its metrics to evaluate the reliability of BMS
