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.

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