Algorithm 1 QR code mapping to VR canvas.

Input:  InputQR[x,y] coordinates of a QR code tracked by Vuforia. Output:  Position[x,y]                ▹ Pointer position on canvas  let n be a top left corner position[x,y] of a QR image  let m be a bottom right corner position[x,y] of a QR image  if QR code IS tracked by Vuforia then       let $minX$, $minY$, $maxX$, $maxY$ be the 4 boundaries of the pointer canvas       $newPos$ = Unity.ScreenPointToLocalPointInRectangle(n,m,InputQR,canvas);              ▹ Mapping from QR coords to a point in the VR canvas       if ($minX\le newPos.X\le maxX$) and ($minY\le newPos.Y\le maxX$) then           position[x,y] = [$newPos.X,newPos.Y$] ▹ Updates pointer position on the canvas       end if  else if QR code IS NOT tracked by Vuforia then       position[x,y] = [$(maxX+minX)/2,(maxY+minY)/2$] ▹ Pointer is set to canvas center  end if
