accuracy: Compute Gaze Accuracy

In ETDQualitizer: Automated Eye Tracking Data Quality Determination for Screen-Based Eye Trackers

Compute Gaze Accuracy

Description

Calculates the angular offset between gaze and target directions.

Usage

accuracy(azi, ele, target_azi, target_ele, central_tendency_fun = mean)

Arguments

azi	Gaze azimuth in degrees.
ele	Gaze elevation in degrees.
target_azi	Target azimuth in degrees.
target_ele	Target elevation in degrees.
central_tendency_fun	Function to compute central tendency (default: mean).

Value

A list with offset, offset_azi, and offset_ele, the total, horizontal and vertical offset of gaze from the target (in degrees).

Examples

accuracy(c(1, 2), c(1, 2), 0, 0)
