AOI_seq {eyetools}R Documentation

Sequence analysis of area of interest entries

Description

Analyses the sequence of entries into defined AOI regions across trials. Can only be used with fixation data with a "fix_n" column denoting fixation events.

Usage

AOI_seq(data, AOIs, AOI_names = NULL, participant_ID = "participant_ID")

Arguments

data

A dataframe with fixation data (from fixation_dispersion). Either single or multi participant data

AOIs

A dataframe of areas of interest (AOIs), with one row per AOI (x, y, width_radius, height).

AOI_names

An optional vector of AOI names to replace the default "AOI_1", "AOI_2", etc.

participant_ID

the variable that determines the participant identifier. If no column present, assumes a single participant

Value

a dataframe containing the sequence of entries into AOIs on each trial, entry/exit/duration time into AOI

Examples


data <- combine_eyes(HCL)
fix_d <- fixation_dispersion(data, participant_ID = "pNum")

AOI_seq(fix_d, AOIs = HCL_AOIs, participant_ID = "pNum")
