+## Timestamped gaze positions
+
+[TimeStampedGazePositions](../../../argaze/#argaze.GazeFeatures.TimeStampedGazePositions) inherits from [TimeStampedBuffer](../../../argaze/#argaze.DataStructures.TimeStampedBuffer) class to handle especially gaze positions.
+
+### Import from dataframe
+
+It is possible to load timestamped gaze positions from a [Pandas DataFrame](https://pandas.pydata.org/docs/getting_started/intro_tutorials/01_table_oriented.html#min-tut-01-tableoriented) object.
+
+```python
+import pandas
+
+# Load gaze positions from a CSV file into Panda Dataframe
+dataframe = pandas.read_csv('gaze_positions.csv', delimiter="\t", low_memory=False)
+
+# Convert Panda dataframe into TimestampedGazePositions buffer precising the use of each specific column labels
+ts_gaze_positions = GazeFeatures.TimeStampedGazePositions.from_dataframe(dataframe, timestamp = 'Recording timestamp [ms]', x = 'Gaze point X [px]', y = 'Gaze point Y [px]')
+
+```
