Bayesian Hierarchical Pointing Models

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 hierarchical pointing model and compare it with the typical pooled pointing models (i.e., treating all observations as the same pool), an…

Select or Suggest? Reinforcement Learning-based Method for High-Accuracy Target Selection on Touchscreens

Suggesting multiple target candidates based on touch input is a possible option for high-accuracy target selection on small touchscreen devices. But it can become overwhelming if suggestions are triggered too often. To address this, we propose SATS, a Suggestion-based Accurate Target Selection method, where target sel…

Variance and Distribution Models for Steering Tasks

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 distribution of MT to ID. In this paper, we propose and evaluate models that predict the variance and distribution of MT based on ID for…

Modeling Two Dimensional Touch Pointing

Modeling touch pointing is essential to touchscreen interface development and research, as pointing is one of the most basic and common touch actions users perform on touchscreen devices. Finger-Fitts Law [4] revised the conventional Fitts’ law into a 1D (one-dimensional) pointing model for finger touch by explicitly…
