    The Effects of Auditory Latency on Experienced First-Person Shooter Players
    (Mensch und Computer 2022 - Tagungsband, 2022) Halbhuber, David; Köhler, Annika; Schmidbauer, Markus; Wiese, Jannik; Henze, Niels
    Latency is inherently part of every interactive system and is particularly critical in video games. Previous work shows that visual latency above 25 ms reduces game experience and player performance. However, latency does not only affect visual perception but also may influence auditory elements of video games. It is unclear if auditory latency impairs the gaming experience and player performance with the same magnitude as visual latency. Therefore, we conducted an experiment with 24 participants playing a first-person shooter game. Participants played with four levels (0 ms, 40 ms, 270 ms, and 500 ms) of controlled auditory latency to reveal effects on game experience and player performance. Our analysis shows that auditory latency in video games increases the perceived tension, decreases positive feelings towards the game, and on its highest tested level (500 ms), even causes significantly stronger associations with negative feelings towards the game. Furthermore, we found that the negative effects of auditory latency are particularly pronounced for high-skilled players. We conclude that auditory latency negatively affects video games and their players. Therefore, researchers should investigate it with the same rigor as visual latency

    Faster Might Not be Fast Enough: Improving Users’ Experience and Performance through Negative Latency
    (Mensch und Computer 2023 - Workshopband, 2023) Henze, Niels; Halbhuber, David; Wiese, Jannik
    All interactive systems have latency. Previous work showed that reducing latency has a wide range of positive effects and suggests that the benefits of reduced latency might continue even when approaching 0 ms of latency. Previouswork also developed approaches to predict users’ inputs and showed these predictions to reduce latencies’ negative effects. We propose to investigate the effects of predicting beyond a system’s latency which would essentially result in negative latency. Our recent work revealed that there is at least one task where negative latency could be beneficial. In this position paper, we discuss the potential impact and identify three challenges for future work.

    Predicting Mouse Positions Beyond a System's Latency Can Increase Throughput and User Experience in Linear Steering Tasks
    (Mensch und Computer 2023 - Tagungsband, 2023) Wiese, Jannik; Henze, Niels
    Latency is present in all interactive systems and decreases user experience and performance. Previous work developed approaches that predict user actions and show these predictions to reduce latencies’ negative effects. While this can increase user experience and performance, it is unclear if predicting beyond a system’s latency results in further improvements. Therefore, we investigated the effects of predicting beyond a system’s latency. We collected data from 60 participants performing Steering Law tasks to systematically train an artificial neural network (ANN) that predicts 100ms into the future. We integrated the ANN into the Steering Law task and buffered users’ inputs to simulate latency between 50ms and -50ms. A study with 30 participants showed that decreasing latency beyond the system’s latency increases throughput up to -50ms. Subjective measures improved up to -16.67ms without negative effects on agency. Overall, we show that predicting beyond a system’s latency can increase performance and user experience.
