Variability in wrist-tilt accelerometer based gesture interfaces [PDF]
In this paper we describe a study that examines human performance in a tilt control targeting task on a PDA. A three-degree of freedom accelerometer attached to the base of the PDA allows users to navigate to the targets by tilting their wrist in ...

Fitts Law as a Restrained Random Walk
Fitts law, one of the rare quantitative relations in psychology, describes the time it takes for a human being to aim at and hit a target of a given size, starting from a given remote position.

Independent Influences of Movement Distance and Visual Distance on Fitts' Law
Fitts’ Law is one among a small number of psychophysical laws. However, a fundamental variable in Fitts’ Law – the movement distance, D – confounds two quantities: the physical distance the effector has to move to reach a goal, and the visually perceived

Performance is not Related to Perception of Target Width in Fitts’ Law
We report a new experiment in a series of studies in which research participants perform a Fitts’ Law repetitive task, and then are required to judge the width of the target that was utilized.

Gaze and head tracking, or pointing, in head-mounted displays enables new input modalities for point-select tasks. We conducted a Fitts' law experiment with 41 subjects comparing head pointing and gaze pointing using a 300 ms dwell (n = 22) or click (n =

The Investigation of Laparoscopic Instrument Movement Control and Learning Effect [PDF]
Laparoscopic surgery avoids large incisions for intra-abdominal operations as required in conventional open surgery. Whereas the patient benefits from laparoscopic techniques, the surgeon encounters new difficulties that were not present during open ...

A Control Model: Interpretation of Fitts' Law [PDF]
The analytical results for several models are given: a first order model where it is assumed that the hand velocity can be directly controlled, and a second order model where it is assumed that the hand acceleration can be directly controlled.
