Modeling User Performance in Multi-Lane Moving-Target Acquisition

Modern video games often feature moving target acquisition (MTA) tasks, where users must press a button when a moving target reaches an acquisition line. User performance models in MTA are useful for quantitative skill analysis and computational game level design, but have so far been constructed only for cases where…

Hardware-Embedded Pointing Transfer Function Capable of Canceling OS Gains

When using indirect pointing devices in modern operating systems (OS), users' perception of the pointing transfer function is easily influenced by the device's hardware or OS-native transfer function settings. This could hinder users from finding and fully adapting to the transfer function that is optimal for them. We…

Effects of Computer Mouse Lift-off Distance Settings in Mouse Lifting Action

This study investigates the effect of Lift-off Distance (LoD) on a computer mouse, which refers to the height at which a mouse sensor stops tracking when lifted off the surface. Although a low LoD is generally preferred to avoid unintentional cursor movement in mouse lifting (=clutching), especially in first-person sh…

Exploring Intervention Techniques to Alleviate Negative Emotions during Video Content Moderation Tasks as a Worker-centered Task Design

Videos are dynamic and multi-modal compared to other types of content, making automatic filtering difficult, which is why content moderators play a crucial role. However, video content moderators are exposed to more profound emotional labor because videos contain rich visual information, sometimes including even harmf…

User Performance in Consecutive Temporal Pointing: An Exploratory Study

A significant amount of research has recently been conducted on user performance in so-called temporal pointing tasks, in which a user is required to perform a button input at the timing required by the system. Consecutive temporal pointing (CTP), in which two consecutive button inputs must be performed while satisfyi…

Quantifying Wrist-Aiming Habits with A Dual-Sensor Mouse: Implications for Player Performance and Workload

Computer mice are widely used today as the primary input device in competitive video games. If a player exhibits more wrist rotation than other players when moving the mouse laterally, the player is said to have stronger wrist-aiming habits. Despite strong public interest, there has been no affordable technique to qua…

Do We Need a Faster Mouse? Empirical Evaluation of Asynchronicity-Induced Jitter

In gaming, accurately rendering input signals on a display is crucial, both spatially and temporally. However, the asynchronicity between the input and output signal frequencies results in unstable responses called "jitter." A recent research modeled this jitter mathematically; however, the effect of jitter on human p…

Secrets of Gosu: Understanding Physical Combat Skills of Professional Players in First-Person Shooters

In first-person shooters (FPS), professional players (a.k.a., Gosu) outperform amateur players. The secrets behind the performance of professional FPS players have been debated in online communities with many conjectures; however, attempts of scientific verification have been limited. We addressed this conundrum throu…

Swap: A Replacement-based Text Revision Technique for Mobile Devices

Text revision is an important task to ensure the accuracy of text content. Revising text on mobile devices is cumbersome and time-consuming due to the imprecise caret control and the repetitive use of the backspace. We present Swap, a novel replacement-based technique to facilitate text revision on mobile devices. We…

Optimal Sensor Position for a Computer Mouse

Computer mice have their displacement sensors in various locations (center, front, and rear). However, there has been little research into the effects of sensor position or on engineering approaches to exploit it. This paper first discusses the mechanisms via which sensor position affects mouse movement and reports th…
