Research Project - VR Environments

Task 5 Antisaccade Street

In this task users will be placed in a city environment. In front of the user there will be two roads. In these roads, we present cars in different colours (randomly generated). User’s task is to look in the opposite direction of where we present the car and press the opposite button of the VR controller depending on where the car is presented. If the car is presented on the left road, user should look on the right road and press the right button of the controller. Same for the right side. Once the car is shown, user looks at the opposite direction where it is shown and after car dissapears, user should look in the light in the park in front of them.

Aims:
To understand users ability to focus on a sustained attention task and their response strategy, response inhibition, or motor impulsivity.

Groups of participants:
-Controls
-People with ADHD/ADHD traits
-People who stutter

Task Details:
For this tasks, there will be city ambient sounds, people talking sounds, birds sound. In front of them there will be people talking, people walking, birds flying. At certain time we also show a plane flying. 50 cars in total will be randomly presented (25 on the left – 25 on the right side) with random colours. Each car will show for 1.15 second and the delay between the cars is 1.15 second. Task is 3:20 minutes long.

Questionnaire:
Q1: Pressing the button for the wrong car direction affected my next responses.
Q2: It was difficult to look and click in the opposite direction of the car.
Q3: I think I did very well in completing this task.
Q4: I think I didn’t do very well in completing this task.
Q5: The task was interesting and was similar to a scenario that can happen in our day-to-day life.
Q6: I felt present and involved in VR.

Data Collected:
-From the task (only when they press the button of the controller, we save username, car shown (left or right), arrow pressed (left or right), accuracy if they were correct/wrong, reaction time (from car shown to their button press), timestamp)
