Online video games and cloud gaming are rapidly growing in pervasiveness. Their resource
demands can put significant stress on the global communication infrastructure. And network …

In interactive systems high latency affects user performance and experience. This is
especially problematic in video games. A large number of studies on this topic investigated …

Measuring Visual Latency in VR and AR devices has become increasingly complicated as
many of the components will influence others in multiple loops and ultimately affect the …

We propose a method for accurately and precisely measuring the intrinsic latency of input
devices and document measurements for 36 keyboards, mice and gamepads connected via …

In current graphical user interfaces, there exists a (typically unavoidable) end-to-end latency
from each pointing-device movement to its corresponding cursor response on the screen …

Steering a cursor through a constrained path is required for operating graphical user
interfaces, such as when navigating a cascaded menu. Recently, the accuracy with which …

We present a low cost method to measure and characterize the end-to-end latency when
using a touch system (tap latency) or an input device equipped with a physical button. Our …

Two formulations of Fitts' index of difficulty ID are empirically compared under different
subjective speed-accuracy biases: the nominal form ID n and the effective form ID e using …

We report on the Latency Hammer, a low-cost yet highaccuracy and high-precision
automated tool that measures the interface latency of touchscreen devices. The Hammer …

Latency is an intrinsic property of all human-computer systems. As it can affect user
experience and performance, it should be kept as low as possible for real-time applications …
