mark a rectangle over playing video

Hello guys, my goal is to be able to play a video frame by frame and then let the user mark with a rectangle chosen object (for example the user should be able to choose faces and chairs from the movie that is beeing displayed) then I would like to find a way to save the properties of the rectangles selected by the user (for example in frame 11 - [x,y,width,hight] of the marked rectangle) but for some reason the rectangle selection appears on a different window, why? how do I resolve this?

this is my code so far:

 videoFReader = vision.VideoFileReader('sample.avi');
videoPlayer = vision.VideoPlayer;
hold on;
imrect;
daspect([1,1,1])
while ~isDone(videoFReader)
  videoFrame = step(videoFReader);
  step(videoPlayer, videoFrame);
end
release(videoPlayer);
release(videoFReader);
