Template repository for matlab analysis project

This script runs a simple routine that will display a red square on the screen that the user can move and rescale till it feels their whole field of view (FOV) on the screen. This can prove useful when the FOV is partly obstructed (like in an fMRI) experiment and hard to measure.

How to install and run

Install

git clone --recurse-submodules https://github.com/cpp-lln-lab/estimate_visual_FOV.git

Set parameters in setParameters.m

Run

mainScript

Experimenter control

When run in cfg.userIsExperimenter = true mode, the experimenter can use the keys

• LeftArrow to move the FOV left
• RightArrow to move the FOV right move the FOV
• UpArrow to move the FOV up
• DownArrow to move the FOV down
• p to scale the FOV up
• m to scale the FOV down

Otherwise check the cfg.keyboard set up in setParameters.

IMPORTANT

Make sure that the values you use in this script are the same as the one you will use in the experiment where you need to adapt the FOV.

    cfg.screen.monitorWidth = FIXME % in cm
    cfg.screen.monitorDistance = FIXME; % distance from the screen in cm
