CodeComprehension dataset [Alakmeh et al., 2024].

This dataset includes eye-tracking-while-code-reading data from a participants in a single session. Eye movements are recorded at a sampling frequency of 1,000 Hz using an EyeLink 1000 eye tracker and are provided as pixel coordinates.

The participant is instructed to read the code snippet and answer a code comprehension question.

name

The name of the dataset.

Type:

str

long_name

The entire name of the dataset.

Type:

str

has_files

Indicate whether the dataset contains ‘gaze’, ‘precomputed_events’, and ‘precomputed_reading_measures’.

Type:

dict[str, bool]

resources

A list of dataset gaze_resources. Each list entry must be a dictionary with the following keys: - resource: The url suffix of the resource. This will be concatenated with the mirror. - filename: The filename under which the file is saved as. - md5: The MD5 checksum of the respective file.

Type:

dict[str, list[dict[str, str]]]

filename_format

Regular expression which will be matched before trying to load the file. Namedgroups will appear in the fileinfo dataframe.

Type:

dict[str, str]

filename_format_schema_overrides

If named groups are present in the filename_format, this makes it possible to cast specific named groups to a particular datatype.

Type:

dict[str, dict[str, type]]

column_map

The keys are the columns to read, the values are the names to which they should be renamed.

Type:

dict[str, str]

custom_read_kwargs

If specified, these keyword arguments will be passed to the file reading function.

Type:

dict[str, dict[str, Any]]

Examples

Initialize your Dataset object with the CodeComprehension definition:

>>> import pymovements as pm
>>>
>>> dataset = pm.Dataset("CodeComprehension", path='data/CodeComprehension')

Download the dataset resources:

>>> dataset.download()

Load the data into memory:

>>> dataset.load()
