One of the most useful tools in human-computer interaction is the task model, a structured
decomposition of user actions toward a goal. Task models can predict average human …

The design of Fitts' historical reciprocal tapping experiment gravely confounds index of
difficulty ID with target distance D: Summary statistics for the candidate Fitts model and a …

Bayesian hierarchical models are probabilistic models that have hierarchical structures and
use Bayesian methods for inferences. In this paper, we extend Fitts' law to be a Bayesian …

Background Training surgeons to use surgical robots are becoming part of surgical training
curricula. We propose a novel method of training fine‐motor skills such as Microscopic …

Touch pointing is one of the primary interaction actions on mobile devices. In this research,
we aim to (1) model touch pointing for people with Parkinson's Disease (PD), and (2) detect …

The tradeoff between speed and accuracy of human movements has been exploited from
many different perspectives, such as experimental psychology, workspace design, human …

The “crossing time” to pass between objects in lassoing tasks is predicted by Fitts' law. When
an unwanted object, or obstacle, intrudes into the user's path, users curve the stroke to avoid …

Steering law reveals a linear relationship between the movement time (MT) and the index of
difficulty (ID) in trajectory-based steering tasks. However, it does not relate the variance or …

Fitts' law, which relates movement time MTin a pointing task to the target's dimensions D and
Wis usually expressed by mimicking Shannon's capacityformula MT= a+ b log 2 (1+ D/W) …

Considering 3D interactions in Virtual-Reality (VR), it is critical to study how visual
awareness of real hands influences users scaled interaction performance in different VR …
