Parking Control Experiment Instructions
Please carefully read the instructions below.
In this experiment, you will be playing a simple game where you try to park a car at a target parking spot, shown by a blue square. The computer knows how to perform this task, and at certain points, will provide you demonstrations of how to park the car and ask you to practice in order to help you improve at the task.NOTE: You must be on a laptop or computer to participate. Additionally, it is important that you do NOT refresh or close the page during the experiment.
The game interface is shown below.
The goal of the game is to park the car in the spot marked by a blue square. To successfully park the car, you must stop the car over the blue square in a vertical orientation (parallel to parking lines). To control the car, you can use your mouse to control the joystick toggle on the interface. The x-axis controls steering (left and right) of the wheel (black circle at front of car). The y-axis controls the forward acceleration of the car.
The experiment consists of three phases.
Phase I: In Phase I, you will have a pre-test with two chances to try parking the car from start to finish. Use the joystick to control the car.
Phase II: In Phase II, you will practice 5 different skills needed to park the car. For each skill, you will alternate between watching a demonstration of the computer performing the skill (Skill Demonstration), either in isolation or combined with another skill, and practicing that particular skill (Skill Practice). There are 5 skills in total. The following two paragraphs give more details on Phase II.
— Skill Demonstrations.
During skill demonstrations, you will watch a video of how the computer completes that skill.
To help you understand how the computer is controlling the car,
the control joystick will move in the direction the computer chooses, and the vehicle will respond accordingly.
The trajectory the car is following is shown in light gray.
You should not touch any controls during these demonstrations.
— Skill Practice.
During skill practice, you will have a chance to practice the same skill that was demonstrated to you by the computer.
To control the car, you should control the joystick on the interface with your computer mouse.
The joystick will move accordingly, as it did during the skill demonstrations.
The trajectory the car should follow from the demo is shown in light gray.
Phase III: In Phase III, you will try to park the car from start to finish. You should try to apply the skills you learned in Phase II. Phase III has five rounds. Use the joystick to control the car.
