This is a skeleton jQuery script (not yet plugin) for polling mouse position and populating a js object with the results, including time stamps and participant id for JSON consumption by a backend data collection system

Result() data object

This is a 'class' for result object, containing all point-wise data

This class has no methods, only properties, which keeps the JSON representation simple and clean.

Attributes:

• participant_id: unique id of participant (researcher-assigned)
• num_points: helper count of the number of recorded datapoints. This is redundant with len(mouse_pos.x), len(mouse_pos.y) and len(time_stamp)
• mouse_pos: Point object with separate arrays of x and y values
• time_stamp: array of time stamp for each point

The JSON representation:

result = {
    participant_id: 'string',
    num_points: int,
    mouse_pos: {
        x: [int,int,...],
        y: [int,int,...]
    },
    time_stamp: [int,int,...]
}
