Reconstruct media presentations as analysis trials

Converts contiguous Gazepoint media runs into explicit trial intervals. This provides stable person-by-item-by-trial keys even when the original export contains no behavioural response file.

Usage

build_gazepoint_media_trials(x, item_map = NULL, overwrite = TRUE)

Arguments

x

An `eye_dataset` imported from Gazepoint.

item_map

Optional data frame or CSV path containing `stimulus_id`, `item_id`, and optionally `condition_id`.

overwrite

Replace existing trial intervals.

Value

The updated `eye_dataset`.
